Welcome to Exam Notes by Dumps4shared! In this article we
will cover Core 1 objective3.8 Given a scenario, select and configure
appropriate components for a custom PC configuration that meets customer
specifications or needs.

We will look at a performance based question and explore how
that question type can address exam objective 3.8. Objective 3.8 aims at
assessing your ability to “Given a scenario, select the appropriate
components for a custom PC configuration that meets customer specifications or
needs.”
 First notice that the exam objective starts by stating “Given
a scenario…”.

This is important because this signals that CompTIA will not be
satisfied with just asking you simple knowledge based question. CompTIA will
want to see you apply this knowledge to a given situation as it would occur in
real life. This is where a Performance Based Question comes in particularly
handy.

The Performance Based Question we have used in this post can also be viewed on our YouTube Channel at

This example (as well as above video) comes from a
Dumps4shared A+ practice test for CompTIA A+ 220-1001:

A+ 220-1001 Performance Based Question (PBQ) – Custom
workstation assembly.

The above screenshot is taken from an exam in Study Mode (choose
Study Mode when you want to be able to see the answers and explanations). The
scenario that sub-objective 3.8 puts you in is one where you are asked to
perform a “custom PC configuration” based on customer specifications or needs.
In this question you are asked to configure a CAD/CAM workstation. Here is the
question as presented:

“You are assembling a CAD/CAM design workstation. From the parts
available choose those that best meet the requirements. Drag the labels to the
correct motherboard locations.”

Keep in mind that since you are configuring a CAD/CAM design
workstation from the parts available, you need to choose parts that meet the
requirements. To achieve that in this performance based question, drag the
appropriate labels to the correct motherboard location. There is a list of components
in the left pane.

A+ practice test question for Exam1 – Starting position

On the right of the screen is a motherboard with highlighted
locations. These are the targets. Here is a portion of 3.8 that highlights the
CAD/CAM design workstation requirements (you will need to know these inside and
out by the time you take the test).

CompTIA A+ 220-1001 Exam Objective 3.8
– CAD/CAM

In order to answer this question, consider making sub-objective 3.8
your virtual answer grid. Here is how we can do this. Under 3.8, CompTIA’s
requirement for a CAD/CAM design workstation is:

A) Multicore processor
B) High-end video
C) Maximum RAM

With that in mind, let’s go back to the choices presented in the
question. After consideration, here is what your A, B, and
C
 answers should be for this question:

A) The first choice is 8GB RAM which is a decent amount but
not the only good amount. Checking the rest of the choices, 32GB is available
and since the requirement is maximum RAM, the choice is simple.
Select 32 GB and drag it to the memory slots on the motherboard.

B)  The answer at the top of the list is the AMD 145 Sempron which
is a decent processor but only has a single core. We need a multicore processor.
The AMD FX-8150 has 8 cores which easily qualifies it as multicore, a label that is assigned to the
processor. Here is where you should realize that knowledge of actual hardware
specifications is as just as critically important to the exam as the exam
objective requirements.

C) The choice is between the Galaxy GeForce GTX760, with 4GB
of memory, and the Nvidia GeForce GT240 that has 1GB of memory. The GTX both outperforms
the GT and has more memory that is also faster. The GTX satisfies CompTIA’s “high-end
video
” requirement. You’ll drag the GTX card to the slot and since we are
in Study mode, we can check the answer:

Success! We get a “Question Answered Correctly” message (see green text at the bottom of the frame). There is also an explanation of what we did and why we did it.

The main take home here is that if 1) you know your components,
and 2) you know the requirements for the different workstations under exam
objective 3.8, then it’s almost hard to miss any of these questions.

Of course, this is not the only performance based question type
on the A+ Core 1 exam. There are others. There is also a distinct difference
between the performance based question in 220-1001 compared to 220-902. In
220-1001, the questions tend to be this kind of “enhanced drag and drop” while
in A+ 220-902, the performance based questions are more software
simulations within the software where you may be asked to perform tasks. Performance
based questions in A+ 220-1002 will be discussed in later.

Please see our narrated video about this question on our YouTube Channel.

We are hoping that if nothing else, you have learned that the
process of elimination combined with your hardware knowledge will allow you to master
any of the questions that address sub-objective 3.8.

That’s all for objective 3.8. Good luck on the test!
