A server is having problems booting into the operating system. Which of the following can provide important information to begin to troubleshoot the cause?

System logs (e.g., Event Viewer in Windows, syslog in Linux) are generated by the operating system after it has successfully loaded, so they are not available if the server fails to boot.

Firmware updates are actions taken to modify or improve the firmware, not a source of troubleshooting information when a boot failure occurs.

POST messages are generated by the system's firmware (BIOS/UEFI) during startup to check essential hardware components such as the CPU, memory, and storage. If the server fails to boot into the operating system, these messages or beep codes can pinpoint which hardware component is preventing successful initialization, making them crucial for early troubleshooting.

Application logs are created by specific software applications running within the operating system, making them irrelevant if the OS fails to boot.
