player accepted to Jay insteadof an A, please follow me there
because I want to be able to doget 1000 followers so then that
(01:51):
way I can go live and do thesetype of question answers online
on Tiktok.
So for those of you who do notknow me, my name is Professor
Jay Rod.
I'm a college professor in theNew York State area and I do
these podcasts based on the comtier series of exams, a plus
that were plus, security plus, Imean I'm then will dabble into
(02:13):
cloud plus and CYSA plus and, asI you know, get further along.
I may be, you know, doing penplus and the like, but again, I
got to know how I'm doing withthe fans.
You know, with the demand isgreat, I'll do it.
You know, I'll do anything formy, for my listeners.
So if there's a particulartopic you want to go up to, you
(02:36):
want to get into, send me anemail at Professor Jay Rod at
gmailcom.
That's Professor Jay R O D atgmailcom.
As I was saying before aboutTiktok, if I get 1000 followers
on Tiktok, they will let me golive.
So, and if I go live, I can dothese questions and answers I
(02:56):
could.
You know, we'll do a couple,you know, one or two a week,
maybe three week, depending howit goes right.
It's up to you guys.
You guys have to, you know,follow me at Professor Jay Rod
on Tiktok.
So if you, if you were able todo that and we get our views up
and our followers up, I'll do alive.
I did a little sound bike onthe CompTIA, a little sound bike
(03:21):
on one of the episodes that Idid on Tiktok, and it quickly
went to 1700 views, which I wasamazed.
So it, listen, the demand isthere, just, you know, just make
sure that you hit that like andand follow me on tiktok and
I'll be more than happy to do alive question and answer
sessions.
You know, to help you with theexam.
(03:42):
I mean, I'm more than more thanhappy to do that with you guys,
but you know the demand has tobe there and you know it has to
be a reason For me to do it.
So you got to email me orfollow me on tiktok.
Listen, I'm not on thisplatform to make a million
dollars, right, I know I'm notgonna be a millionaire on this
thing, but there are someexpenses that I occur from here
(04:04):
that I, you know, if I can getit covered, be nice.
So you know, like I said, it'snot all about, it's not about
the money.
I just want to.
I like to help my students.
But you know, it'd be nice ifsome of these expenses, you know
, get covered by you know, notby you, but you know, just by by
doing other stuff, like pullingup social media and let the
(04:26):
commercials pay, right, theadvertising space.
All right, now that we got thatout of the way.
Let's go on to come to yourquestions.
These are, you know, no onequestions that I've seen on the
internet and we can go over itAll right.
So the format is I'll read thequestion and the answers, I'll
read it again and Then we'll goover it, all right.
First question is a technicianpowers out a PC and it's monitor
(04:51):
, a PC and it's monitor and seesthe following error message no
input signal detected.
The display lights on thecomputer are on.
Which of the following is apossible solution?
A change the BIOS settings.
Be changing the connectorsettings of the monitor, see
checking the power plug on themonitor.
And be Taking the power plug onthe PC.
(05:12):
So I'll read it again aTechnician powers on a PC and
its monitor and sees thefollowing error messages no
input.
Error message no input signaldetected.
Right, that's the message.
The display lights on thecomputer are on.
Which of the following is apossible solution?
A changing the BIOS settings.
Be changing the connectorsettings on the monitor see
(05:35):
Checking the power plug on themonitor and the checking the
power plug on the PC.
So and this is what I don't likeabout, come to you sometimes.
I mean, you know, it's notreally that far apart.
It is what it is.
You know, we'll I alwaysemphasize about the OSI model,
right, that you know, firstthing you want to do is do a
level one which is physicallayer Right, and in the physical
(06:00):
layer, one of the first thingsthat it's in the physical layer
is check your cables, right.
But in this case, even thoughthey have C and D, checking the
power plug on the monitor andthe check the power plug on PC,
I Think the reason why come toyou put both of these as
Possible answers, because ifthey just put one, that's the
(06:21):
one that other people gonna goto Right.
So they put both of these for areason right now, no input
signal device, but the displaylights of the computer are on,
which means you don't need tocheck the power plug on the
monitor because the monitorturns on, and also you don't
(06:42):
need to check the power plug onthe PC because the PC is on.
So you're left with a changingthe bio setting.
Error B changing the connectorsetting on the monitor.
So the answer is what, ladiesand gentlemen?
Yes, just be, that's just be.
A is incorrect because the bioscannot be seen as an input,
(07:03):
cannot be, it won't.
Should give you the error noinput signal detected.
If it was bios Right Checkingthe power plug.
While that could be a solution,the problem states that the
technician has already poweredon already and also with the PC.
So the correct answers be sinceboth the PC and the monitor on
(07:26):
on, using the monitor settingsto verify it has the right input
is the way to go.
All right question to a Companyjust bought a printer capable
of automatically printing onboth sides of the paper.
However, after installation, thetechnician can only print on
both sides of the paper on thepage manually.
(07:47):
Which of the following shouldthe technician do to fix the
issue?
A Install the most recentfirmware upgrade available for
the printer.
B contact the vendor for ourhardware replacement.
C Reinstalled the printersoftware and drivers and then we
start printer.
Or.
D we didn't installation manualand configured to click
(08:07):
settings.
I read it again a company justbought a printer capable of
automatically printing on bothsides of paper.
After installation, however,the technician can only print on
both sides of the papermanually.
Which of the following shouldthe technician do to fix this?
A install the most recentfirmware upgrade available for
the printer.
(08:27):
B contact the vendor forhardware replacement.
C, we install the printersoftware and drivers and then we
start the printer, or D we theinstallation manual and
configure duplex settings.
There's a big clue here.
To big clues is Both a printerand after installation Right, so
(08:49):
he had just bought it.
It's just installing it, right,so that will Get which one you
can knock out of there.
But you could knock out.
Contact the vendor for ourreplacement, right, you can
knock that out.
You know a, c and D, any one ofthem.
You know it's a, it's a goodone, but the firmware upgrade
(09:13):
would not do anything for theprinter, right, so you can
eliminate that.
And then you left withreinstall the printer software
on the drivers and then be selfprinter, or read the
installation manual andconfigure duplex settings, since
he just bought the printer andhe is installing Right.
Then, and there the answer is Dwe the installation manual and
(09:35):
configure duplex settings.
That is your answer.
Hopefully you got it All right.
Next question A laptop has beenreturned for screen repair.
The owner insists that thescreen is broken, but
occasionally a faded image isable to be seen in very bright
settings on the desktop.
Which of the following stepsshould the repair technician
(10:00):
take first a Replace thegraphics card.
B Replace the screen, as thecustomer insists.
C Recommend the usage of anexternal display instead.
And.
B Ensure that the backlight isfunctioning as expected.
I'll read it again A laptop hasbeen returned for screen repair
.
The owner insists that thescreen is broken, but
(10:22):
occasionally a faded image isable to be seen in very bright
settings on the desktop.
Which of the following stepsshould the repair technician
take first?
B Replace the graphics card.
B Replace the screen, as thecustomer insisted.
C Recommend the usage of anexternal display instead.
Or ensure that the backlight isfunctioning as expected.
(10:48):
When it first is the clue here,and I always tell my students it
may not be the answer, it maynot be the fix for it, what you
try first, but you always wantto try something first and that
(11:13):
might not be the answer.
But out of all of, whatever thesituation is, there's a way of
pecking order where you shouldtry.
So, for example, if you'rehaving something issue with a
battery on your laptop, you'renot going to take the RAM, the
(11:34):
hard drive, the CD out of thelaptop.
That's not going to be thefirst thing you try.
That might be the problem withthe laptop.
If it doesn't turn on.
Maybe the RAM, maybe the harddrive, something, maybe
something's loose.
That might be the problem forthe first.
That's not the first thing youwant to try, and that's an area.
You would take out the battery.
(11:55):
You see the battery today, soyou're back on.
That'll be the first thing youdo.
So just because you may chooseone answer.
It may not be the right answerfor the fix, but it's the right
answer for the idea.
Hope that makes sense.
All right, so replace thegraphics card, replace the
screen, as a customer insists,recommend the users have been
(12:16):
external display instead andensure that the backlight is
functioning as expected.
There is a clue in the questionwhere it says a fainted image
is able to be seen in verybright settings on the desktop,
which means you don't need toreplace the graphic card or the
screen.
Right, the answer is D ensurethe backlight is functioning as
(12:38):
expected.
You need to check that out.
You need to ensure thebacklight is functioning as
expected.
The technician should firstcheck the backlight, as a fact
that a fainted image can be seenin bright settings suggests
that the issue may be with thebacklight and not the screen
itself.
If the backlight is notfunctioning as expected, the
technician can then proceed withrepairing or replacing this.
(12:58):
If the backlight is functioningcorrectly, then the technician
came along to other possiblecauses of the issue, right, so
the backlight might not be theissue, but that's the one you
want to start, right, before yougo to any other possible
solution.
All right, next, a technicianreplace a motherboard on a
(13:19):
server and now the 64-bithypervisor is not loading
correctly.
Which of the following needs tobe enabled for the hypervisor
to run?
A hardware prefetcher B,hyperthreading C, d-pro D, bd,
dash D.
I'll read it again A technicianreplace a motherboard on a
(13:41):
server and now the 64-bithypervisor is not loading
correctly.
Which of the following needs tobe enabled for the hypervisor
to run?
A hardware prefetcher B,hyperthreading C, d-pro D, bd,
dash D.
What do you think?
The answer is, ladies andgentlemen.
The answer is D, bd dash D,which stands for virtualization
(14:10):
technology, for directed item O.
That needs to be enabled forthe hypervisor to run.
Vt dash D is a hardware leveltechnology that enables direct
assignments of physical devicesto virtual machines.
This allows for improvedsecurity and isolation of a
virtual environment, which iscritical for running a
(14:33):
hypervisor.
If VD dash D is not enabled,the hypervisor may not be able
to access the physical hardwareresources in need, causing
issues with loading and runningcorrectly.
So for that one, the answer isD, alright, next one.
This one is a little easy, thisone, you should get it.
(14:57):
Users mobile phone gets reallyhot to the touch and does not
retain a charge.
The user also reports that thephone is very slow, especially
while charging.
Which of the following is mostlikely causing these systems A
broken charging port, bdigitizer failure, c CPU
overheating and D defectivebattery.
(15:19):
I'll read it again Our usersmobile phone gets really hot to
the touch and does not retain acharge.
The user also reports that thephone is very slow, especially
while charging.
Which of the following is mostlikely causing these symptoms?
A broken charging port, ddigitizer failure, c CPU
overheating and D defectivebattery.
(15:41):
So the reason why I picked thisquestion, ladies and gentlemen,
because it has one word that youalways have to remember and
come to you and that's the wordend.
Right the word, and when yousee that in com to you, it, or a
comma, right it, has twoconditions that you, that the
(16:05):
answer must be.
The answer must be bothconditions.
So here is a user's mobilephone gets really hot to the
touch and it does not retain acharge, right.
And then the other issue isalso, reports of the phone is
very slow, especially why chargeit.
So in here you actually havethree conditions, which is, you
(16:28):
know, for a one Question.
You know usually they choose towhen they have a couple issues.
But we can work with this,right, let's see.
So a broken charging port Willnot get it.
You know I might do some ofthese things Right, you know
(16:48):
broken charging port will not,does not retain the charge right
, could do that, and the reportsof the phone is slow while
charging, but it's not gonna abroken charging for it's not
gonna get the phone top.
So that's how.
Digitizer failure is not gonnado any of these.
So that's how CPU overheatingand you have you the defective
(17:12):
battery.
All right, what do you do?
The answer is things in general.
Those are the two choices,right.
What do you think it is?
You got it All right.
The answer is D the effect ofbatteries, most likely the cause
of the symptoms described forthe user's mobile phone Getting
really hot to the touch, notretaining a charge and being
(17:34):
very slow, especially bycharging.
A defective battery may nothold the charge properly,
leading to the phone running outof power quickly and the need
for frequent charging.
The defective battery may alsocause the phone to overheat,
especially while charging, asthe battery attempts to charge
fulfills to hold the charge,resulting in the battery
(17:55):
continuing to draw power andgenerating heat.
A Broken charging port ordigitizer failure would not
cause the phone to get hot oraffect ability the batteries
ability to hold the charge.
Cpu overheating may cause thephone to get hot, but it's less
likely to affect the battery'sability to hold the charge.
My CPU and battery are twodifferent things, so the answers
(18:16):
is D All right.
Next one this is the one thatsome students of mine they
usually have a little bit of anissue with, so let's go through
it.
Which of the following networkdevices is used to separate
broadcast domains?
A switch be wireless accesspoint C router, d hub.
(18:39):
Again, I read again which ofthe following network devices is
used to separate broadcastdomains?
A switch be wireless accesspoint C router the hub.
What do you think?
The answers?
Think what you think and theanswer is See router.
(19:01):
Right, a router is used toseparate broadcast domains.
A Router operates at the layerthree of the OSI model, which is
the network layer and access aboundary between different
networks, uses routing tables todetermine the best path for
data to travel from one networkto another.
Routers also allow the use ofNAT network address table or
(19:23):
translation to translate privateIP addresses public IP
addresses, allowing multipledevices on a private network to
access the internet using asingle public IP.
Additionally, routers are usedto separate broadcast domains,
which means that broadcasted byone device in the network are
not forwarded to other deviceson the same network.
(19:44):
They go out a different network, effectively limiting the size
of the broadcast domain andreducing congestion.
So the answer is C router.
All right, that was a good one,all right.
Here is a printing questionwhich is com Tia.
It is very Like it's actuallythe last question the com Tia
(20:07):
likes to to give you Laserprinter questions.
Right, laser printer questionsare out of all the four.
You know they have a duplex,they have Different kind of
printers.
Move, I can't Impact printerlaser, printer, 3ds and 3ds.
(20:33):
Now, what do you call those,those ones, those hot ones?
I'm throwing a blank,embarrassing, but there's a
couple that we have there.
So it, this is good, all right.
So just remember what laser is.
(20:53):
Number one, right?
Laser is the one that you haveto be Most focused mostly on.
So it'll be good if youConcentrate.
If you're gonna concentrate onprinters, concentrate on that,
on laser and how they print.
You know what could go wrongdifferent.
(21:13):
You know if you, if you'remissing a toner, toner.
You know what happens if theroller stops working.
What happens.
You know if your Corona wirestops working, if you transfer
wire stops working.
Those stuff like that they wantto know.
They're very heavy on that forlaser first, all right.
(21:34):
Last question a user in amedical office contacts a
technician regarding a printerthat's used to print a four size
labels.
I.
After the labels are printed,they mistakenly contained a
white space in the middle of thepage.
Which of the following willmost likely be the cause?
A Contaminated user.
(21:55):
B Warned rollers.
C, a mince feed or D Pageorientation.
I'll read it again A user in amedical office contested a
technician regarding a printerthat is used to print an
A4-sized label.
After the labels are printed,they mistakenly contained white
space in the middle of the page.
(22:17):
Which of the following willmost likely be the cause?
A Contaminated user.
B Warned rollers.
C, a mince feed and D Pageorientation.
So one of the things that theydo here is like, sometimes they
give you information that'suseless, right and I call that
(22:37):
the MacGuffin.
That's something that they usein movies Right, when they give
you kind of like too muchinformation or information
that's useless, like a user inthe medical office, right,
ignore that, right, that doesn'tmean anything, right, just
because he's in the medicaloffice, you know, that doesn't.
It's not anything special.
(22:57):
And sometimes Contia will throwthose in Thinking that you
would say, wow, it's a medicaloffice.
I gotta think you know adifferent way, you don't, right,
it's just medical office,lawyer's office, it's the same
thing, it's an office, right?
So don't make too much of a bigdeal about that.
(23:20):
It's a medical office, soalright.
So what do you think it is?
So you think it's contaminatedrollers, worn rollers, sorry,
(23:41):
contaminated fuser, worn rollers, a misfeed page or a page
orientation.
Well, a misfeed is a misfeed,right?
That means you know it'sjamming, right?
So we're not gonna worry aboutthat, right, that's out,
automatically out, because amisfeed is a misfeed.
(24:03):
Worn rollers will do what to it, to your printer?
If your rollers are worn, thatactually will cause your paper
to jab.
Hence a misfeed, right.
So you left with pageorientation and contaminated
(24:24):
fuser.
So the and remember it has awhite space in the middle right.
The most likely cause of labelsprinted with white space in the
middle of HD, in the middle ofthe page, is deep Page
orientation.
A contaminated fuser mightcause issues with the quality of
the print or leading to smudge,but it's unlikely to result in
(24:47):
white space in the middle of thepage.
Worn rollers can cause paperfeed issues or paper jams, but
they usually don't result inwhite space in the middle of the
page.
A misfeed can cause the paperto be improperly fed through the
paper, leading to print issues,but it's not the primary cause
of the white space in the middleof the page.
(25:08):
If the page orientationsettings in the printer driver
or software are not correctlyconfigured to match the label
size A4, it can lead to whitespace in the middle of the page.
For example, if the software isset to print labels in portrait
mode while the labels aredesigned for landscaping
(25:30):
printing, you may see whitespace in the middle of the page
because the printer is expectinga different layout.
This, ladies and gentlemen, ishow you tackle these types of
questions.
On CompTIA Now.
I just want to remind everyonethat, please.
(25:50):
I hope you enjoyed thequestions right.
If you got them all right,you're on your way for passing
the 1101.
If you struggled a little bit,hey, this is what we're here for
.
It's practice.
Let's tell my students let'smake our mistakes here.
So when we pay for our exams wedon't make the mistakes there.
(26:12):
So we can make all the mistakesthat we want here.
And I encourage mistakes.
Even I make mistakes.
You know I'm not perfect.
These podcasts are definitelynot perfect, but you know we are
trying very hard to improve it.
So, as a reminder again, pleasefollow me on TikTok.
(26:32):
I have Professor J-RodS-P-R-O-F-E-S-S-O-R-J-R-O-D.
If I get a thousand followers,according to several students of
mine, I will be able tobroadcast live, and I would like
to broadcast live thesequestions so that we can go over
(26:54):
.
It'll be nice.
This will be something nicethat I would like to do for you
guys and we can do.
You know, a-plus, that we'replus three, plus right, it's all
up to you.
And you know I'll send out timeand date and all that.

went to 1700 views, which I wasamazed.
So it, listen, the demand isthere, just, you know, just make
sure that you hit that like andand follow me on tiktok and
I'll be more than happy to do alive question and answer
sessions.
You know, to help you with theexam.
(03:42):
I mean, I'm more than more thanhappy to do that with you guys,
but you know the demand has tobe there and you know it has to
be a reason For me to do it.
So you got to email me orfollow me on tiktok.
Listen, I'm not on thisplatform to make a million
dollars, right, I know I'm notgonna be a millionaire on this
thing, but there are someexpenses that I occur from here
(04:04):
that I, you know, if I can getit covered, be nice.
So you know, like I said, it'snot all about, it's not about
the money.
I just want to.
I like to help my students.
But you know, it'd be nice ifsome of these expenses, you know
, get covered by you know, notby you, but you know, just by by
doing other stuff, like pullingup social media and let the
(04:26):
commercials pay, right, theadvertising space.
All right, now that we got thatout of the way.
Let's go on to come to yourquestions.
These are, you know, no onequestions that I've seen on the
internet and we can go over itAll right.
So the format is I'll read thequestion and the answers, I'll
read it again and Then we'll goover it, all right.
First question is a technicianpowers out a PC and it's monitor
(04:51):
, a PC and it's monitor and seesthe following error message no
input signal detected.
The display lights on thecomputer are on.
Which of the following is apossible solution?
A change the BIOS settings.
Be changing the connectorsettings of the monitor, see
checking the power plug on themonitor.
And be Taking the power plug onthe PC.
(05:12):
So I'll read it again aTechnician powers on a PC and
its monitor and sees thefollowing error messages no
input.
Error message no input signaldetected.
Right, that's the message.
The display lights on thecomputer are on.
Which of the following is apossible solution?
A changing the BIOS settings.
Be changing the connectorsettings on the monitor see
(05:35):
Checking the power plug on themonitor and the checking the
power plug on the PC.
So and this is what I don't likeabout, come to you sometimes.
I mean, you know, it's notreally that far apart.
It is what it is.
You know, we'll I alwaysemphasize about the OSI model,
right, that you know, firstthing you want to do is do a
level one which is physicallayer Right, and in the physical
(06:00):
layer, one of the first thingsthat it's in the physical layer
is check your cables, right.
But in this case, even thoughthey have C and D, checking the
power plug on the monitor andthe check the power plug on PC,
I Think the reason why come toyou put both of these as
Possible answers, because ifthey just put one, that's the
(06:21):
one that other people gonna goto Right.
So they put both of these for areason right now, no input
signal device, but the displaylights of the computer are on,
which means you don't need tocheck the power plug on the
monitor because the monitorturns on, and also you don't
(06:42):
need to check the power plug onthe PC because the PC is on.
So you're left with a changingthe bio setting.
Error B changing the connectorsetting on the monitor.
So the answer is what, ladiesand gentlemen?
Yes, just be, that's just be.
A is incorrect because the bioscannot be seen as an input,
(07:03):
cannot be, it won't.
Should give you the error noinput signal detected.
If it was bios Right Checkingthe power plug.
While that could be a solution,the problem states that the
technician has already poweredon already and also with the PC.
So the correct answers be sinceboth the PC and the monitor on
(07:26):
on, using the monitor settingsto verify it has the right input
is the way to go.
All right question to a Companyjust bought a printer capable
of automatically printing onboth sides of the paper.
However, after installation, thetechnician can only print on
both sides of the paper on thepage manually.
(07:47):
Which of the following shouldthe technician do to fix the
issue?
A Install the most recentfirmware upgrade available for
the printer.
B contact the vendor for ourhardware replacement.
C Reinstalled the printersoftware and drivers and then we
start printer.
Or.
D we didn't installation manualand configured to click
(08:07):
settings.
I read it again a company justbought a printer capable of
automatically printing on bothsides of paper.
After installation, however,the technician can only print on
both sides of the papermanually.
Which of the following shouldthe technician do to fix this?
A install the most recentfirmware upgrade available for
the printer.
(08:27):
B contact the vendor forhardware replacement.
C, we install the printersoftware and drivers and then we
start the printer, or D we theinstallation manual and
configure duplex settings.
There's a big clue here.
To big clues is Both a printerand after installation Right, so
(08:49):
he had just bought it.
It's just installing it, right,so that will Get which one you
can knock out of there.
But you could knock out.
Contact the vendor for ourreplacement, right, you can
knock that out.
You know a, c and D, any one ofthem.
You know it's a, it's a goodone, but the firmware upgrade
(09:13):
would not do anything for theprinter, right, so you can
eliminate that.
And then you left withreinstall the printer software
on the drivers and then be selfprinter, or read the
installation manual andconfigure duplex settings, since
he just bought the printer andhe is installing Right.
Then, and there the answer is Dwe the installation manual and
(09:35):
configure duplex settings.
That is your answer.
Hopefully you got it All right.
Next question A laptop has beenreturned for screen repair.
The owner insists that thescreen is broken, but
occasionally a faded image isable to be seen in very bright
settings on the desktop.
Which of the following stepsshould the repair technician
(10:00):
take first a Replace thegraphics card.
B Replace the screen, as thecustomer insists.
C Recommend the usage of anexternal display instead.
And.
B Ensure that the backlight isfunctioning as expected.
I'll read it again A laptop hasbeen returned for screen repair
.
The owner insists that thescreen is broken, but
(10:22):
occasionally a faded image isable to be seen in very bright
settings on the desktop.
Which of the following stepsshould the repair technician
take first?
B Replace the graphics card.
B Replace the screen, as thecustomer insisted.
C Recommend the usage of anexternal display instead.
Or ensure that the backlight isfunctioning as expected.
(10:48):
When it first is the clue here,and I always tell my students it
may not be the answer, it maynot be the fix for it, what you
try first, but you always wantto try something first and that
(11:13):
might not be the answer.
But out of all of, whatever thesituation is, there's a way of
pecking order where you shouldtry.
So, for example, if you'rehaving something issue with a
battery on your laptop, you'renot going to take the RAM, the
(11:34):
hard drive, the CD out of thelaptop.
That's not going to be thefirst thing you try.
That might be the problem withthe laptop.
If it doesn't turn on.
Maybe the RAM, maybe the harddrive, something, maybe
something's loose.
That might be the problem forthe first.
That's not the first thing youwant to try, and that's an area.
You would take out the battery.
(11:55):
You see the battery today, soyou're back on.
That'll be the first thing youdo.
So just because you may chooseone answer.
It may not be the right answerfor the fix, but it's the right
answer for the idea.
Hope that makes sense.
All right, so replace thegraphics card, replace the
screen, as a customer insists,recommend the users have been
(12:16):
external display instead andensure that the backlight is
functioning as expected.
There is a clue in the questionwhere it says a fainted image
is able to be seen in verybright settings on the desktop,
which means you don't need toreplace the graphic card or the
screen.
Right, the answer is D ensurethe backlight is functioning as
(12:38):
expected.
You need to check that out.
You need to ensure thebacklight is functioning as
expected.
The technician should firstcheck the backlight, as a fact
that a fainted image can be seenin bright settings suggests
that the issue may be with thebacklight and not the screen
itself.
If the backlight is notfunctioning as expected, the
technician can then proceed withrepairing or replacing this.
(12:58):
If the backlight is functioningcorrectly, then the technician
came along to other possiblecauses of the issue, right, so
the backlight might not be theissue, but that's the one you
want to start, right, before yougo to any other possible
solution.
All right, next, a technicianreplace a motherboard on a
(13:19):
server and now the 64-bithypervisor is not loading
correctly.
Which of the following needs tobe enabled for the hypervisor
to run?
A hardware prefetcher B,hyperthreading C, d-pro D, bd,
dash D.
I'll read it again A technicianreplace a motherboard on a
(13:41):
server and now the 64-bithypervisor is not loading
correctly.
Which of the following needs tobe enabled for the hypervisor
to run?
A hardware prefetcher B,hyperthreading C, d-pro D, bd,
dash D.
What do you think?
The answer is, ladies andgentlemen.
The answer is D, bd dash D,which stands for virtualization
(14:10):
technology, for directed item O.
That needs to be enabled forthe hypervisor to run.
Vt dash D is a hardware leveltechnology that enables direct
assignments of physical devicesto virtual machines.
This allows for improvedsecurity and isolation of a
virtual environment, which iscritical for running a
(14:33):
hypervisor.
If VD dash D is not enabled,the hypervisor may not be able
to access the physical hardwareresources in need, causing
issues with loading and runningcorrectly.
So for that one, the answer isD, alright, next one.
This one is a little easy, thisone, you should get it.
(14:57):
Users mobile phone gets reallyhot to the touch and does not
retain a charge.
The user also reports that thephone is very slow, especially
while charging.
Which of the following is mostlikely causing these systems A
broken charging port, bdigitizer failure, c CPU
overheating and D defectivebattery.
(15:19):
I'll read it again Our usersmobile phone gets really hot to
the touch and does not retain acharge.
The user also reports that thephone is very slow, especially
while charging.
Which of the following is mostlikely causing these symptoms?
A broken charging port, ddigitizer failure, c CPU
overheating and D defectivebattery.
(15:41):
So the reason why I picked thisquestion, ladies and gentlemen,
because it has one word that youalways have to remember and
come to you and that's the wordend.
Right the word, and when yousee that in com to you, it, or a
comma, right it, has twoconditions that you, that the
(16:05):
answer must be.
The answer must be bothconditions.
So here is a user's mobilephone gets really hot to the
touch and it does not retain acharge, right.
And then the other issue isalso, reports of the phone is
very slow, especially why chargeit.
So in here you actually havethree conditions, which is, you
(16:28):
know, for a one Question.
You know usually they choose towhen they have a couple issues.
But we can work with this,right, let's see.
So a broken charging port Willnot get it.
You know I might do some ofthese things Right, you know
(16:48):
broken charging port will not,does not retain the charge right
, could do that, and the reportsof the phone is slow while
charging, but it's not gonna abroken charging for it's not
gonna get the phone top.
So that's how.
Digitizer failure is not gonnado any of these.
So that's how CPU overheatingand you have you the defective
(17:12):
battery.
All right, what do you do?
The answer is things in general.
Those are the two choices,right.
What do you think it is?
You got it All right.
The answer is D the effect ofbatteries, most likely the cause
of the symptoms described forthe user's mobile phone Getting
really hot to the touch, notretaining a charge and being
(17:34):
very slow, especially bycharging.
A defective battery may nothold the charge properly,
leading to the phone running outof power quickly and the need
for frequent charging.
The defective battery may alsocause the phone to overheat,
especially while charging, asthe battery attempts to charge
fulfills to hold the charge,resulting in the battery
(17:55):
continuing to draw power andgenerating heat.
A Broken charging port ordigitizer failure would not
cause the phone to get hot oraffect ability the batteries
ability to hold the charge.
Cpu overheating may cause thephone to get hot, but it's less
likely to affect the battery'sability to hold the charge.
My CPU and battery are twodifferent things, so the answers
(18:16):
is D All right.
Next one this is the one thatsome students of mine they
usually have a little bit of anissue with, so let's go through
it.
Which of the following networkdevices is used to separate
broadcast domains?
A switch be wireless accesspoint C router, d hub.
(18:39):
Again, I read again which ofthe following network devices is
used to separate broadcastdomains?
A switch be wireless accesspoint C router the hub.
What do you think?
The answers?
Think what you think and theanswer is See router.
(19:01):
Right, a router is used toseparate broadcast domains.
A Router operates at the layerthree of the OSI model, which is
the network layer and access aboundary between different
networks, uses routing tables todetermine the best path for
data to travel from one networkto another.
Routers also allow the use ofNAT network address table or
(19:23):
translation to translate privateIP addresses public IP
addresses, allowing multipledevices on a private network to
access the internet using asingle public IP.
Additionally, routers are usedto separate broadcast domains,
which means that broadcasted byone device in the network are
not forwarded to other deviceson the same network.
(19:44):
They go out a different network, effectively limiting the size
of the broadcast domain andreducing congestion.
So the answer is C router.
All right, that was a good one,all right.
Here is a printing questionwhich is com Tia.
It is very Like it's actuallythe last question the com Tia
(20:07):
likes to to give you Laserprinter questions.
Right, laser printer questionsare out of all the four.
You know they have a duplex,they have Different kind of
printers.
Move, I can't Impact printerlaser, printer, 3ds and 3ds.
(20:33):
Now, what do you call those,those ones, those hot ones?
I'm throwing a blank,embarrassing, but there's a
couple that we have there.
So it, this is good, all right.
So just remember what laser is.
(20:53):
Number one, right?
Laser is the one that you haveto be Most focused mostly on.
So it'll be good if youConcentrate.
If you're gonna concentrate onprinters, concentrate on that,
on laser and how they print.
You know what could go wrongdifferent.
(21:13):
You know if you, if you'remissing a toner, toner.
You know what happens if theroller stops working.
What happens.
You know if your Corona wirestops working, if you transfer
wire stops working.
Those stuff like that they wantto know.
They're very heavy on that forlaser first, all right.
(21:34):
Last question a user in amedical office contacts a
technician regarding a printerthat's used to print a four size
labels.
I.
After the labels are printed,they mistakenly contained a
white space in the middle of thepage.
Which of the following willmost likely be the cause?
A Contaminated user.
(21:55):
B Warned rollers.
C, a mince feed or D Pageorientation.
I'll read it again A user in amedical office contested a
technician regarding a printerthat is used to print an
A4-sized label.
After the labels are printed,they mistakenly contained white
space in the middle of the page.
(22:17):
Which of the following willmost likely be the cause?
A Contaminated user.
B Warned rollers.
C, a mince feed and D Pageorientation.
So one of the things that theydo here is like, sometimes they
give you information that'suseless, right and I call that
(22:37):
the MacGuffin.
That's something that they usein movies Right, when they give
you kind of like too muchinformation or information
that's useless, like a user inthe medical office, right,
ignore that, right, that doesn'tmean anything, right, just
because he's in the medicaloffice, you know, that doesn't.
It's not anything special.
(22:57):
And sometimes Contia will throwthose in Thinking that you
would say, wow, it's a medicaloffice.
I gotta think you know adifferent way, you don't, right,
it's just medical office,lawyer's office, it's the same
thing, it's an office, right?
So don't make too much of a bigdeal about that.
(23:20):
It's a medical office, soalright.
So what do you think it is?
So you think it's contaminatedrollers, worn rollers, sorry,
(23:41):
contaminated fuser, worn rollers, a misfeed page or a page
orientation.
Well, a misfeed is a misfeed,right?
That means you know it'sjamming, right?
So we're not gonna worry aboutthat, right, that's out,
automatically out, because amisfeed is a misfeed.
(24:03):
Worn rollers will do what to it, to your printer?
If your rollers are worn, thatactually will cause your paper
to jab.
Hence a misfeed, right.
So you left with pageorientation and contaminated
(24:24):
fuser.
So the and remember it has awhite space in the middle right.
The most likely cause of labelsprinted with white space in the
middle of HD, in the middle ofthe page, is deep Page
orientation.
A contaminated fuser mightcause issues with the quality of
the print or leading to smudge,but it's unlikely to result in
(24:47):
white space in the middle of thepage.
Worn rollers can cause paperfeed issues or paper jams, but
they usually don't result inwhite space in the middle of the
page.
A misfeed can cause the paperto be improperly fed through the
paper, leading to print issues,but it's not the primary cause
of the white space in the middleof the page.
(25:08):
If the page orientationsettings in the printer driver
or software are not correctlyconfigured to match the label
size A4, it can lead to whitespace in the middle of the page.
For example, if the software isset to print labels in portrait
mode while the labels aredesigned for landscaping
(25:30):
printing, you may see whitespace in the middle of the page
because the printer is expectinga different layout.
This, ladies and gentlemen, ishow you tackle these types of
questions.
On CompTIA Now.
I just want to remind everyonethat, please.
(25:50):
I hope you enjoyed thequestions right.
If you got them all right,you're on your way for passing
the 1101.
If you struggled a little bit,hey, this is what we're here for
.
It's practice.
Let's tell my students let'smake our mistakes here.
So when we pay for our exams wedon't make the mistakes there.
(26:12):
So we can make all the mistakesthat we want here.
And I encourage mistakes.
Even I make mistakes.
You know I'm not perfect.
These podcasts are definitelynot perfect, but you know we are
trying very hard to improve it.
So, as a reminder again, pleasefollow me on TikTok.
(26:32):
I have Professor J-RodS-P-R-O-F-E-S-S-O-R-J-R-O-D.
If I get a thousand followers,according to several students of
mine, I will be able tobroadcast live, and I would like
to broadcast live thesequestions so that we can go over
(26:54):
.
It'll be nice.
This will be something nicethat I would like to do for you
guys and we can do.
You know, a-plus, that we'replus three, plus right, it's all
up to you.
And you know I'll send out timeand date and all that.
That we can do it.
You know I won't forget myEuropean fans out there.
(27:14):
We can do it Also.
You can chime in, would love todo this for you guys to do the
form of media.
I'll still do the podcasting,of course, but I would love to
see you guys on TikTok as well.
Don't know how to use it, butyou know we'll learn.
I guess you guys will teach meRight.
