DOMAIN 1: IT CONCEPTS AND TERMINOLOGY (13%)
Question 1
A technician is documenting system specifications and encounters the memory address 0x4F.
What notational system is being used, and what is its decimal equivalent?
A) Binary; 1001111
B) Octal; 79
C) Hexadecimal; 79
D) Decimal; 4F
-” detailed answer 100 % correct :-”C) Hexadecimal; 79
, 2
Rationale: The prefix 0x denotes hexadecimal notation (base 16). To convert 0x4F to decimal: 4
× 16¹ = 64 and F = 15 × 16⁰ = 15, totaling 79. Binary representation would be 01001111, not an
option here.
Question 2
A user reports their computer is running slowly. According to the CompTIA troubleshooting
methodology, what should be the technician's FIRST step?
A) Replace the RAM modules immediately
B) Identify the problem by gathering information from the user
C) Establish a theory of probable cause
D) Document the findings and solution
-” detailed answer 100 % correct :-”B) Identify the problem by gathering information
from the user
Rationale: The CompTIA troubleshooting methodology begins with identifying the problem.
This involves gathering information from the user, questioning the obvious, and performing
initial observations before any action is taken.
Question 3
Which of the following BEST describes the difference between volatile and non-volatile
memory?
A) Volatile memory is faster; non-volatile memory is slower
B) Volatile memory loses data when power is removed; non-volatile memory retains data
without power
C) Volatile memory is used only in servers; non-volatile memory is used only in mobile devices
D) Volatile memory stores the operating system; non-volatile memory stores user files
-” detailed answer 100 % correct :-”B) Volatile memory loses data when power is
removed; non-volatile memory retains data without power
Rationale: Volatile memory (e.g., RAM) requires continuous power to maintain stored data and
loses all information when power is interrupted. Non-volatile memory (e.g., HDD, SSD, NVMe)
retains data even when power is removed.

Question 4
A technician needs to represent the decimal number 255 in binary. Which of the following is the
correct binary representation?
A) 11111111
B) 10000000
C) 11110000
D) 11111110
-” detailed answer 100 % correct :-”A) 11111111
Rationale: In binary (base 2), each position represents a power of 2. 255 decimal equals 2⁸ - 1,
which is represented as eight 1s: 11111111. This is the maximum value for an 8-bit unsigned
binary number.
Question 5
A systems administrator is troubleshooting a network connectivity issue. After implementing a
solution, what is the NEXT step according to the CompTIA troubleshooting methodology?
A) Document findings, actions, and outcomes
B) Verify full system functionality
C) Escalate the issue to a senior technician
D) Close the ticket without further action
-” detailed answer 100 % correct :-”B) Verify full system functionality
Rationale: After implementing a solution, the next critical step is to verify full system
functionality. Documentation comes after verification.
Question 6
Which of the following units of measurement is used to express processor speed?
A) GB (Gigabytes)
B) GHz (Gigahertz)
C) Mbps (Megabits per second)
D) TB (Terabytes)
-” detailed answer 100 % correct :-”B) GHz (Gigahertz)
, 4
Rationale: Processor (CPU) speed is measured in hertz (Hz), typically gigahertz (GHz). GB and TB
measure storage capacity, while Mbps measures data transfer throughput.
Question 7
A technician is explaining the computing cycle to a new hire. Which of the following represents
the correct order of the computing cycle?
A) Output → Processing → Storage → Input
B) Input → Processing → Output → Storage
C) Storage → Input → Output → Processing
D) Processing → Input → Storage → Output
-” detailed answer 100 % correct :-”B) Input → Processing → Output → Storage
Rationale: The computing cycle follows the fundamental sequence: input (data entry),
processing (data manipulation), output (results presentation), and storage (data preservation).
Question 8
What is the decimal equivalent of the hexadecimal number 1A?
A) 16
B) 26
C) 42
D) 10
-” detailed answer 100 % correct :-”B) 26
Rationale: Hexadecimal 1A converts as: 1 × 16¹ = 16 and A = 10 × 16⁰ = 10, totaling 26.
Hexadecimal uses base 16 with digits 0-9 and A-F representing values 10-15.
Question 9
A user's computer fails to boot. The technician observes that the system beeps three times
before shutting down. According to troubleshooting methodology, what should the technician
do NEXT after identifying the problem?
A) Replace the power supply immediately
B) Establish a theory of probable cause
