CompTIA A+ Core 1 (220-1001) — Question 411

A user notices the system clock is changed every morning. The computer is shut down daily. A technician checks the time zone and finds it is correct, and then checks the BIOS settings and finds the time to be incorrect.
Which of the following is MOST likely the problem?

Answer options

• A. The CMOS battery does not have a charge.
• B. Daylight savings time is not enabled.
• C. BIOS time is set to Universal Time Coordinated.
• D. The NTP server has gone offline.

Correct answer: A

Explanation

The most likely problem is that the CMOS battery does not have a charge, which would cause the BIOS to lose the time setting when the computer is powered off. The other options are less likely; for example, daylight savings time being disabled would not cause a total loss of time, and the BIOS time being set to UTC or an NTP server being offline would not affect the internal clock maintained by the CMOS battery.
