When troubleshooting a computer, you should:
Correct Answer
D. Troubleshoot from the outside in (from the peripHerals in)
Explanation
When troubleshooting a computer, it is recommended to troubleshoot from the outside in (from the peripherals in). This means starting with the external devices such as the monitor, keyboard, and mouse, and then moving towards the internal components like the motherboard. This approach helps to identify and isolate any potential issues that may be caused by external devices before delving into more complex internal problems. It allows for a systematic and efficient troubleshooting process, ensuring that all possible causes are explored in a logical order.

Which of the following error messages might you receive when there is a problem with ram? Choose all that apply.
Correct Answer(s)
A. Memory address error
B. Memory test fails
D. Memory parity error
Explanation
When there is a problem with RAM, you might receive the error messages "Memory address error," "Memory test fails," and "Memory parity error." A memory address error occurs when there is an issue with accessing a specific memory address. A memory test fails error indicates that the RAM failed a diagnostic test. A memory parity error occurs when there is a discrepancy in the parity bit, which is used for error detection in RAM. Therefore, these three error messages are all associated with problems related to RAM.
8.
Which of the following error messages might you receive when there is a keyboard problem? Choose all that apply.
Correct Answer(s)
B. Kb/interface error
C. Gate A20 failure
Explanation
When there is a keyboard problem, you might receive the error messages "Kb/interface error" and "Gate A20 failure". These messages indicate issues with the keyboard or its interface, such as a faulty connection or a problem with the A20 gate, which is responsible for allowing access to extended memory. The other options, "Checksum error" and "Fix keyboard 0 failure," do not specifically relate to keyboard problems.
9.
What does a checksum error represent?
Correct Answer
D. A problem with CMOS
Explanation
A checksum error represents a problem with CMOS. CMOS (Complementary Metal-Oxide-Semiconductor) is a small amount of memory on a computer's motherboard that stores the BIOS (Basic Input/Output System) settings. The checksum is a value that is calculated based on the data stored in CMOS, and it is used to verify the integrity of the data. If a checksum error occurs, it means that the data in CMOS has been corrupted or altered, indicating a problem with CMOS itself.

Which of the following could be used to fix windows start-up problem? Choose all that apply.
Correct Answer(s)
A. Use last know good configuration
B. Use safe mode
Explanation
The options "Use last known good configuration" and "Use safe mode" could be used to fix a Windows start-up problem. "Last known good configuration" allows the system to revert to a previous state where it was known to be functioning properly. "Safe mode" starts the computer with only the necessary drivers and services, allowing troubleshooting and potential resolution of start-up issues. Both options provide methods to diagnose and resolve start-up problems in Windows.
