Question
A technician is troubleshooting a desktop PC that is plugged into a UPS. The PC loses the system date/time after every power outage. Which of the following should the technician do to resolve the issue? (Choose two.)
- A. Run a BIOS update.
- B. Swap out the RAM.
- C. Disable NTP in the OS.
- D. Repair the backup power source. Correct
- E. Replace the CMOS battery. Correct
- F. Install a surge protector.
Explanation
The real-time clock settings survive power loss only while the CMOS battery is good, so a PC that forgets its date and time after outages needs a new CMOS battery. The PC is also on a UPS, which should have kept it powered through the outage; because it lost power, the UPS (the backup power source) is failing and must be repaired or its battery replaced. A BIOS update, new RAM or a surge protector does not keep the clock running, and disabling NTP would remove the only way the OS can correct the time.
