EXAM QUESTIONS
Q1: A technician is building a new gaming PC and needs to select a motherboard that supports
the latest Intel Core i9-13900K processor. Which socket type must the motherboard have?
A. LGA 1151
B. LGA 1200
C. LGA 1700
D. AM4
Correct Answer: C [CORRECT]
Rationale: The Intel Core i9-13900K uses the LGA 1700 socket, which supports Intel's 12th and
13th generation processors. LGA 1151 and LGA 1200 are older Intel sockets, while AM4 is an
AMD socket.
Q2: A user reports that their computer takes an unusually long time to boot and frequently
shows "Disk 100% usage" in Task Manager. The system has a 1TB 7200 RPM mechanical hard
drive. What would be the MOST effective hardware upgrade to improve performance?
A. Install additional SATA cables
B. Replace the motherboard
C. Add more RAM
D. Replace the HDD with an NVMe SSD
Correct Answer: D [CORRECT]
Rationale: Upgrading from a mechanical HDD to an NVMe SSD provides exponentially faster
read/write speeds (up to 3500 MB/s vs ~150 MB/s for HDDs), dramatically reducing boot times
and resolving disk bottleneck issues. The other options do not address the storage speed
bottleneck.
,Q3: A technician is installing RAM into a new system and notices the motherboard has four
DIMM slots color-coded black and gray in alternating pairs. The technician installs two matching
8GB DDR4 modules in slots A1 and B1 (both gray). What configuration is being implemented?
A. Single channel
B. Dual channel
C. Triple channel
D. Quad channel
Correct Answer: B [CORRECT]
Rationale: Installing matching RAM modules in corresponding color-coded slots (A1 and B1)
enables dual-channel memory operation, which doubles the memory bandwidth from 64-bit to
128-bit. Single channel would use adjacent slots, and triple/quad channel require specific
chipset support.
Q4: Which power supply efficiency rating indicates that the PSU delivers at least 87% efficiency
at 20% load, 90% at 50% load, and 87% at 100% load?
A. 80 PLUS Bronze
B. 80 PLUS Silver
C. 80 PLUS Gold
D. 80 PLUS Platinum
Correct Answer: C [CORRECT]
Rationale: 80 PLUS Gold certification requires 87% efficiency at 20% load, 90% at 50% load, and
87% at 100% load. Bronze is less efficient (82%, 85%, 82%), Silver is slightly better (85%, 88%,
85%), and Platinum is more efficient (90%, 92%, 89%).
Q5: SCENARIO: A computer emits a series of beeps on startup (one long, two short) and the
screen remains blank. The system was working fine yesterday, but now it will not display
anything.
Q5: Based on the beep code sequence (one long, two short), which component is MOST likely
the cause of the issue?
A. Power supply failure
B. CPU overheating
, C. Video card failure
D. RAM not seated properly
Correct Answer: C [CORRECT]
Rationale: The one long, two short beep code on most systems (particularly AMI BIOS) indicates
a video card error or display adapter failure. This could be due to a loose connection, faulty
GPU, or insufficient power to the video card. Power supply issues typically produce no beeps,
and RAM issues produce different beep patterns.
Q6: CONTINUING SCENARIO (refer to Q5): The technician reseats the video card and checks the
power connections, but the beep code persists. What should the technician do NEXT?
A. Replace the motherboard
B. Test the system with a known-good video card
C. Reset the BIOS using the CMOS battery
D. Test the monitor on another computer
Correct Answer: B [CORRECT]
Rationale: The next logical step in the troubleshooting process is to test with a known-good
video card to confirm whether the original card has failed. Testing the monitor (D) is a valid step
but should have been done earlier. Replacing the motherboard is premature, and CMOS reset is
unlikely to resolve a hardware beep code.
Q7: CONTINUING SCENARIO (refer to Q5): After installing a known-good video card, the system
boots normally. What is the MOST appropriate next step?
A. Reinstall the original video card to confirm the issue
B. Install the latest drivers for the new video card
C. Document the issue and proceed with replacing the failed video card
D. Run Windows Update to check for system updates
Correct Answer: C [CORRECT]
Rationale: Once the faulty component has been identified (failed video card), the proper
troubleshooting step is to document the findings and replace the failed component. Reinstalling
the faulty card would reintroduce the problem, and driver installation only applies to the
working replacement.
