Troubleshooting Server Issues: Power Outage, Configuration Loss, and Access Problems
Question
Following a recent power outage, a server in the datacenter has been constantly going offline and losing its configuration.
Users have been experiencing access issues while using the application on the server.
The server technician notices the data and time are incorrect when the server is online.
All other servers are working.
Which of the following would MOST likely cause this issue? (Choose two.)
A.
The server has a faulty power supply B.
The server has a CMOS battery failure C.
The server requires OS updates D.
The server has a malfunctioning LED panel E.
The servers do not have NTP configured F.
The time synchronization service is disabled on the servers.
CF.

Based on the scenario provided, the server in question is experiencing frequent power outages, losing its configuration, and has incorrect date and time when online. The fact that all other servers are working suggests that the power outage did not affect the entire data center.
The two most likely causes of the issue are:
B. The server has a CMOS battery failure: The CMOS (Complementary Metal-Oxide-Semiconductor) battery is responsible for providing power to the motherboard's real-time clock. If this battery fails, the real-time clock will lose power, and the system will not be able to keep accurate time. This can cause problems with applications that rely on time-sensitive data, such as logging and security. A failed CMOS battery can also cause the server to lose its configuration settings, which could explain why the server is going offline frequently.
F. The time synchronization service is disabled on the servers: Time synchronization is critical for servers to ensure that they are running in sync with each other and with other systems on the network. If the time synchronization service is disabled, the server's clock will not be updated automatically, and the server will not be able to keep accurate time. This could cause problems with applications that rely on time-sensitive data, as mentioned above.
Therefore, the most likely causes of the issue are a CMOS battery failure and the time synchronization service being disabled on the server. To resolve this issue, the server technician should replace the CMOS battery and enable the time synchronization service on the server.
