After power is restored, a server does not boot and the LED indicators flash. What is the MOST likely cause?

• A. Faulty RAM
• B. Corrupted boot sector
• C. Faulty power supply
• D. Overheating components

Answer: (C)

When a server does not boot after power is restored and you observe flashing LED indicators, the most likely cause is a faulty power supply. The power supply is essential for providing the necessary voltage and current to the server's components. If it fails or is unable to deliver adequate power, the server may not be able to initiate the boot process. Flashing LED indicators serve as diagnostic tools, often indicating that there is an issue with power distribution or that the server is unable to perform a self-test. This scenario aligns closely with power supply issues, as inadequate power can lead to erratic behavior in other components, including RAM and motherboard functions. While faulty RAM can cause boot failures, it usually triggers beep codes or error messages instead of just flashing LED indicators. A corrupted boot sector typically results in a different error message or behavior during the boot process. Overheating components may prevent a server from booting, but this is more likely to occur during extended use rather than immediately after power restoration. Thus, the symptoms described in the scenario point most strongly to a power supply issue.
