Section 1: Hardware & Peripheral Devices (Q1-16)
Q1. A technician is building a workstation for video editing and needs a CPU that can
handle multiple rendering tasks simultaneously. Which CPU specification is most
relevant to this requirement?
A. Higher clock speed only
B. More cores and threads
C. Larger L1 cache only
D. Lower thermal design power (TDP)
B. More cores and threads [CORRECT]
Rationale: Video rendering is highly parallelized; more cores and threads allow
simultaneous processing of multiple tasks. Clock speed affects single-threaded
performance, cache improves data access, and lower TDP relates to power efficiency,
not parallel processing capability.
Correct Answer: B
Q2. A user needs to transfer a 5GB video file from an external drive to their
computer. Which storage interface offers the fastest data transfer speed?
A. USB 2.0
B. USB 3.2 Gen 2x2
C. USB 1.1
D. eSATA 3Gbps
B. USB 3.2 Gen 2x2 [CORRECT]
,2
Rationale: USB 3.2 Gen 2x2 offers up to 20 Gbps, significantly faster than USB 2.0
(480 Mbps), USB 1.1 (12 Mbps), and eSATA 3Gbps (3 Gbps). It is the optimal choice
for large file transfers.
Correct Answer: B
Q3. A technician is installing a high-end graphics card into a desktop computer.
Which expansion slot type is required?
A. PCIe x1
B. PCIe x16
C. PCI (legacy)
D. AGP (legacy)
B. PCIe x16 [CORRECT]
Rationale: Modern high-end graphics cards require PCIe x16 slots for maximum
bandwidth. PCIe x1 is for low-bandwidth devices, and PCI/AGP are obsolete legacy
standards.
Correct Answer: B
Q4. A company needs to print high-volume, high-quality black-and-white documents
for a legal department. Which printer type is most appropriate?
A. Inkjet printer
B. Thermal printer
C. Laser printer
D. Impact (dot matrix) printer
C. Laser printer [CORRECT]
Rationale: Laser printers offer the best combination of speed, cost per page, and
print quality for high-volume black-and-white document printing. Inkjet is slower
and more expensive per page; thermal is for receipts; impact is for multipart forms.

Correct Answer: C
Q5. A technician notices that a computer's CMOS settings are lost every time the
system is unplugged. Which component should be replaced?
A. RAM modules
B. CMOS battery
C. CPU
D. Power supply unit
B. CMOS battery [CORRECT]
Rationale: The CMOS battery (typically a CR2032 lithium coin cell) maintains
BIOS/UEFI settings and real-time clock when AC power is removed. A dead battery
causes settings loss.
Correct Answer: B
Q6. A user wants to connect a laptop to an external 4K monitor using a single cable
that carries both video and data. Which connection type should the technician
recommend?
A. VGA
B. HDMI 1.4
C. Thunderbolt 4
D. DVI-D
C. Thunderbolt 4 [CORRECT]
Rationale: Thunderbolt 4 supports up to 8K video, 40 Gbps data transfer, and power
delivery through a single USB-C connector. VGA and DVI are analog/legacy; HDMI
1.4 supports 4K but only at 30Hz.
Correct Answer: C

Q7. A server administrator needs to configure a RAID array that provides both
performance improvement and fault tolerance using a minimum of three drives.
Which RAID level should be selected?
A. RAID 0
B. RAID 1
C. RAID 5
D. RAID 10
C. RAID 5 [CORRECT]
Rationale: RAID 5 stripes data across three or more drives with distributed parity,
providing both read performance improvement and single-drive fault tolerance. RAID
0 has no fault tolerance, RAID 1 requires only two drives, and RAID 10 requires four
drives.
Correct Answer: C
Q8. A technician is troubleshooting a computer that randomly shuts down under
heavy load. The system has adequate RAM and storage. Which component is most
likely failing?
A. Network interface card
B. Power supply unit with insufficient wattage or failing capacitors
C. Keyboard
D. Monitor
B. Power supply unit with insufficient wattage or failing capacitors [CORRECT]
Rationale: Random shutdowns under load typically indicate power delivery issues. An
underpowered or failing PSU cannot maintain stable voltage during high-demand
scenarios. Network cards, keyboards, and monitors do not cause system shutdowns.
Correct Answer: B
