CompTIA A+ Certification Exam: Core 1 Sample Questions (Q396-Q401):NEW QUESTION # 396
A technician starts a recently built desktop PC for the first time, and the fans power on. However, the PC does not POST, and nothing displays on the monitor. Which of the following should the technician do NEXT to troubleshoot the issue?
A. Check for OS error codes.
B. Replace the CMOS battery.
C. Reseat the system memory.
D. Replace the monitor.
Answer: C
Explanation:
If a newly built PC powers on (meaning the fans spin up) but it doesn't POST (Power-On Self- Test) and there's nothing displayed on the monitor, it's most likely a hardware issue rather than something related to the operating system or monitor.
The most common troubleshooting step in this scenario is: Reseat the system memory.
Ensuring that the RAM modules are properly seated can often resolve POST issues. It's not uncommon for RAM to be slightly unseated during assembly, or for there to be some obstruction (like dust) in the RAM slot.

NEW QUESTION # 398
Which of the following twisted pair cables supports 10GBASE-T data transmission speed?
A. Cat 3
B. Cat 6a
C. Cat 5e
D. Cat 5
Answer: B
Explanation:
Explanation
The correct answer is D. Cat 6a.
Cat 6a (augmented) is a type of twisted pair cable that supports 10GBASE-T data transmission speed.
10GBASE-T is an Ethernet standard that can deliver 10 gigabits per second (Gbps) over copper cables. Cat 6a can support this speed up to a distance of 100 meters, which is the same as Cat 5e and Cat 6 for lower speeds.
Cat 6a has better shielding and crosstalk prevention than Cat 6, which makes it more suitable for high-frequency signals.
Cat 3, Cat 5, and Cat 5e are not capable of supporting 10GBASE-T data transmission speed. Cat 3 can only support up to 10 Mbps, Cat 5 can only support up to 100 Mbps, and Cat 5e can only support up to 1 Gbps.
These cables have lower bandwidth, higher attenuation, and more interference than Cat 6a.
