Question 46
A systems administrator resolves a persistent issue with a laptop. Which of the following steps should the administrator take next?
Show answer and explanation
Correct answer: B. Document the findings.
After resolving a persistent issue, the next step in the CompTIA troubleshooting methodology is to document the findings. Documentation captures what the problem was, what solution was implemented, and the results, which is critical for knowledge management and future reference. This occurs after implementation but before closing the ticket.
Why the other options are wrong
- A. Testing the theory comes before implementation, not after resolution.
- C. Creating an action plan occurs before implementation, not after the issue is resolved.
- D. Implementing the action plan is done before documenting findings, not after.
Question 47
A technician needs to install input devices while setting up a new desktop PC. Which of the following should the technician install? (Choose two.)
Show answer and explanation
Correct answer: B, C. Mouse; Keyboard
Input devices are hardware that allow users to send data and commands to a computer. A mouse and keyboard are the standard input peripherals for a desktop PC, allowing users to interact with the system.
Why the other options are wrong
- A. A printer is an output device, not an input device; it produces physical output from digital data.
- D. A CPU is an internal processor component, not a peripheral input device.
- E. A speaker is an output device that produces audio; it does not accept input from the user.
- F. An SSD is internal storage, not an input device for user interaction.
Question 48
A programmer needs to create a space in an application code to hold a value. The value will be updated periodically when the code is executed. Which of the following should the programmer use?
Show answer and explanation
Correct answer: A. Variable
A variable is a named storage location that holds a value which can be modified during program execution. This matches the requirement for space that holds a value and is updated periodically when code runs. Sequences define ordered operations, loops repeat code blocks, and constants hold fixed unchanging values, none of which allow periodic updates to their stored values.
Why the other options are wrong
- B. Sequence refers to the order of execution, not a storage location for values.
- C. Loop is a control structure for repetition, not a container for holding and updating values.
- D. Constant holds a fixed value that cannot be updated during execution.
