Question 1
A technician is troubleshooting a server that is exhibiting unusually slow performance. After
gathering information from users and reproducing the issue, what is the technician's NEXT step
according to the CompTIA troubleshooting methodology?
A) Immediately restart the server to clear temporary issues
B) Establish a theory of probable cause
C) Document the findings and escalate to a senior engineer
D) Replace the server's RAM modules
-” detailed answer 100 % correct :-”B) Establish a theory of probable cause
Rationale: Following the CompTIA troubleshooting methodology, after identifying the problem
(gathering information and reproducing the issue), the next step is to establish a theory of
probable cause. This involves considering likely causes before testing theories or implementing
solutions.
Question 2
What is the octal equivalent of the decimal number 42?
A) 52
B) 42
C) 62
D) 50
-” detailed answer 100 % correct :-”A) 52
Rationale: To convert decimal 42 to octal (base 8), divide by 8: 42 ÷ 8 = 5 remainder 2, so the
octal representation is 52 (5 × 8¹ + 2 × 8⁰ = 40 + 2 = 42).

Question 3
Which of the following sequences correctly represents the computing cycle of a basic computer
system?
A) Storage → Processing → Input → Output
B) Output → Input → Storage → Processing
C) Input → Processing → Output → Storage
D) Processing → Storage → Input → Output
-” detailed answer 100 % correct :-”C) Input → Processing → Output → Storage
Rationale: The fundamental computing cycle follows the sequence: Input (data entry) →
Processing (data manipulation by CPU) → Output (presentation of results) → Storage (persistent
data saving). This represents the flow of data through a computer system.
Question 4
A technician is documenting system specifications and records a value as 0x3F. What decimal
value does this hexadecimal number represent?
A) 39
B) 63
C) 61
D) 57
-” detailed answer 100 % correct :-”B) 63
Rationale: Hexadecimal 0x3F converts as: 3 × 16¹ = 48 and F = 15 × 16⁰ = 15, totaling 63.
The 0x prefix indicates hexadecimal notation.
Question 5
A user reports that their computer "won't turn on." The technician asks what happened just
before the issue started. This action falls under which troubleshooting step?
A) Establishing a theory of probable cause
B) Testing the theory
C) Identifying the problem
D) Documenting findings
-” detailed answer 100 % correct :-”C) Identifying the problem
, 4
Rationale: Asking the user what happened before the issue occurred is part of identifying the
problem, which includes gathering information from the user and questioning the obvious. This
is the first step in the CompTIA troubleshooting methodology.
Question 6
Which of the following correctly describes the difference between binary and hexadecimal
number systems?
A) Binary uses base-10; hexadecimal uses base-16
B) Binary uses base-2; hexadecimal uses base-16
C) Binary uses base-16; hexadecimal uses base-2
D) Binary and hexadecimal are identical
-” detailed answer 100 % correct :-”B) Binary uses base-2; hexadecimal uses base-16
Rationale: Binary is a base-2 number system using only 0 and 1. Hexadecimal is a base-16
system using digits 0-9 and letters A-F. Each hexadecimal digit represents exactly 4 binary digits,
making it a convenient shorthand for binary.
Question 7
After implementing a solution to resolve a network connectivity issue, the technician verifies
that the user can now access all required resources. What is the FINAL step in the
troubleshooting process?
A) Close the ticket and move to the next issue
B) Document findings, actions taken, and outcomes
C) Inform the user that the issue is resolved
D) Reboot the system to ensure stability
-” detailed answer 100 % correct :-”B) Document findings, actions taken, and
outcomes
Rationale: After verifying full system functionality, the final step in the CompTIA
troubleshooting methodology is to document findings, actions, and outcomes. Proper
documentation creates a knowledge base for future reference.
Question 8
The value 11111111 in binary represents which decimal number?
