I've come across what seems to be conflicting information in a
downloaded Certkiller PDF. See two questions I've come across, below:

Question: When a bearing in the power supply fan goes out. What should
you replace?
A. Fan
B. Case
C. Bearing
D. Power Supply

Answer: A

I thought the fan was part of the power supply, and that the correct
answer is / would be (on the exam at least) "D" the Power Supply.
Even if it is possible to replace only the fan (which I'm not sure
of)... what would the answer on the exam be?

Question: Which priority settings are given to the SCSI ID number?
(CHOOSE TWO)
A. 0 lowest
B. 0 highest
C. 1 lowest
D. 15 lowest
E. 15 highest

Answer: A&E

I thought that the answer was "B & D".

Anyone know which is correct?

This is the kind of stuff that really frustrates me.

I don't work with this stuff every day, so studying / memory is all I
have to pass the exams - so incorrect information really bites.

I would usually have, in my vehicle, a couple different power supplies
out of the, maybe 6 to 8 types I might encounter. So the odds might be 1
in 4 of a success. I would usually have about four different size 12
volt fans, so the odds were better on the fan. And if I did replace the
power supply, I would take it back to the shop and replace the fan and
keep it as a spare. So anyway you hack it, the fan gets replaced. I
have not found one that I could not replace. The answer a. the fan is
correct.

I would quite reading Certkiller junk.

The fan inside the PSU is not considered a FRU. Although it is quite easy
to get at, the test answer is to replace the PSU.

B and D is correct... if I remember SCSI. It is rarley seen, and when it
is, you rarely have to contend with SCSI ID numbers (other than to make
sure no two devices have the same number).

That may be the correct technician's answer, but for the test, it is not.
This is a typical case of the book being wrong for real life.

This is also a perect example of why techs with experience often fail the
exams if they do not study for it. You know what to do for real world,
but for the test, you would fail that question (not you Dave, just the
collective "you").

FRU's are Field Replaceable Units. A PSU is a FRU, but the fan inside of
it is not. I guess the thought process is if the fan stopped, there may
be some heat damage inside the PSU. This could lead to a premature
failure of the PSU. So the idea is to replace the unit.

However, in real life, I can change a fan too- and have many, many times.

I have actually replaced a fan in the field. I keep a soldering gun and
solder with me. Some fans are not soldered into the power supply circuit
board but a lot of them are so I would go with replacing the power supply.
At least for the CompTIA A+ Cert test anyway.
Just like the correct answer is replace Montor because A+ tech is not
certified to go inside monitor and fix it.
I didn't actually see that specific question on the test I took. I guess I
was lucky!!

As I remember "A+ Fourth Edition" by Charles J. Brooks, the answer is
replace the fan in the power supply.
I kinda think the book sucks tough.

I got the scsi question completely wrong.
