Question 1
A technician is assembling a desktop computer and must choose the component that performs most of the arithmetic
and logical operations. The technician also needs to ensure the component has adequate cooling. Which hardware
component is primarily responsible for these processing tasks?
A. The central processing unit (CPU), which executes instructions and requires appropriate thermal management
B. The hard disk drive, which stores data permanently but does not execute program instructions
C. The power supply unit, which converts electricity but performs no computation
D. The monitor, which only displays output generated by other components
Correct Answer: A
Rationale:
The CPU is the primary processing component that executes instructions. Storage, power, and display devices do not perform the
core arithmetic and logic operations.
Question 2
A user complains that a laptop runs slowly when many applications are open. The technician checks resource usage
and finds memory consistently near capacity. Which type of memory is most likely the bottleneck, and what is its key
characteristic?
A. Random-access memory (RAM), which provides temporary, high-speed storage for active programs and data
B. Read-only memory (ROM), which permanently stores firmware and cannot be written during normal operation
C. Optical disc storage, which is used only for distributing software media
D. The CPU cache alone, which is measured in megabytes and never affects multitasking
Correct Answer: A
Rationale:
Insufficient RAM forces the system to use slower virtual memory on disk, degrading performance. ROM and optical media are not
the primary working memory for open applications.
Question 3
A student is learning binary representation. The student converts the decimal number 13 into binary. Which binary
value correctly represents decimal 13?
A. 1101, calculated as 8 + 4 + 0 + 1
B. 1010, which equals decimal 10
C. 1110, which equals decimal 14
D. 1001, which equals decimal 9
Correct Answer: A
Rationale:
13 in binary is 1101 (8+4+1). The other listed patterns correspond to different decimal values.

Question 4
A computer will not boot and the technician suspects a failed power supply. Which symptom most strongly supports
this diagnosis?
A. No lights, no fan movement, and no POST activity when the power button is pressed
B. The operating system loads but one application crashes intermittently
C. The display shows a clear image but the keyboard is unresponsive
D. Network connectivity is lost while all other functions remain normal
Correct Answer: A
Rationale:
A failed PSU typically results in a completely dead system with no power indicators or fan spin. Application crashes, keyboard
issues, or isolated network loss point to other components.
Question 5
A technician must explain the difference between volatile and non-volatile storage to a client. Which statement
correctly distinguishes the two?
A. Volatile memory such as RAM loses its contents when power is removed; non-volatile storage such as SSD retains data
without power
B. Volatile storage always retains data permanently while non-volatile memory is erased on every reboot
C. Both types of storage lose data immediately when the computer is turned off
D. Non-volatile memory is used only for temporary calculations during program execution
Correct Answer: A
Rationale:
RAM is volatile and cleared on power loss; SSDs, HDDs, and flash storage are non-volatile and retain data. The other statements
reverse or misstate these properties.
Question 6
A support technician encounters a situation involving motherboard form factors and expansion slot types. Accurate
identification of hardware concepts is required to resolve the issue. Which explanation or action is most correct?
A. Apply standard hardware knowledge related to motherboard form factors and expansion slot types to diagnose or explain
the component function accurately
B. Ignore manufacturer specifications and rely solely on visual inspection without testing
C. Replace every component in the system without isolating the failing part
D. Assume all storage devices are identical in speed and reliability regardless of technology
Correct Answer: A
Rationale:
Correct handling of motherboard form factors and expansion slot types requires precise hardware knowledge. Blind replacement
or ignoring specifications wastes time and may not fix the root cause.
