SECTION 1: HARDWARE & PERIPHERALS
Questions 1–30
Question 1
A workstation administrator is configuring a new system for graphics designers, and the users
have requested the fastest possible storage speed for reading and writing data. Which of the
following would be the BEST choice for this requirement?
A) 10 TB NAS
B) 8 TB HDD
C) 5 TB SAN
D) 2 TB SSD
Correct answer: D
Rationale: SSDs (Solid State Drives) have the fastest read/write speeds among storage options
because they use flash memory with no moving parts. NAS and SAN are network storage
solutions that introduce network latency. HDDs are slower mechanical drives .
Question 2
A user in the marketing department needs an LCD with the best possible color representation.
Which of the following would be the BEST choice for this requirement?
A) TN
B) CCFL
C) IPS
D) VA
,Correct answer: C
Rationale: IPS (In-Plane Switching) displays offer the most accurate and vibrant color
representation, making them ideal for professional design work. TN panels have faster response
times but poorer color accuracy. VA panels are a compromise between TN and IPS. CCFL
refers to backlight technology, not panel type .
Question 3
A technician is upgrading the RAM on a laptop computer. Which of the following would BEST
describe the memory required for this upgrade?
A) SSD
B) SO-DIMM
C) CMOS
D) ECC
Correct answer: B
Rationale: SO-DIMM (Small Outline Dual In-line Memory Module) is the smaller form factor
memory used in laptops. SSD is storage, CMOS stores BIOS settings, and ECC is
error-correcting memory typically used in servers .
Question 4
Which type of connector is commonly used to connect an external storage device?
A) F-connector
B) ST
C) eSATA
D) Molex
Correct answer: C
Rationale: eSATA (External Serial Advanced Technology Attachment) is specifically designed for
connecting external storage devices with SATA-like performance. F-connectors are for cable TV,
ST is fiber optic, and Molex is an internal power connector .
, Question 5
What is the maximum throughput of USB 3.0 (SuperSpeed USB)?
A) 480 Mbps
B) 5 Gbps
C) 10 Gbps
D) 20 Gbps
Correct answer: B
Rationale: USB 3.0 (SuperSpeed USB) has a maximum theoretical throughput of 5 Gbps. USB
2.0 is 480 Mbps, USB 3.1 Gen 2 is 10 Gbps, and USB 3.2 Gen 2×2 is 20 Gbps .
Question 6
A PC technician has been asked to replace the LCD on a touch-screen laptop computer. Which
of the following would be the MOST important component to test after this replacement?
A) Digitizer
B) Keyboard
C) Audio controls
D) System memory
Correct answer: A
Rationale: The digitizer is the component that converts touch input to digital signals. After
replacing a touch-screen LCD, the digitizer must be tested to ensure touch functionality works
properly .
Question 7
A user has attempted to charge their iPhone, but the charging icon does not appear when
connecting the charging cable. A working cable from another iPhone exhibits the same
symptoms. Which of the following is the MOST likely reason?
A) The screen is locked
B) An iOS update is pending
C) The iPhone has low signal
D) The Lightning port is damaged
