Question

A server fails to recognize a newly installed PCIe NIC. What is the most likely cause?

Answers

correct

The NIC is incompatible with the OS
The NIC is not connected to a switch
The server's RAM is full
The power supply is too strong

Explanation

Correct Answer: a. The NIC is incompatible with the OS

If a server fails to recognize a newly installed PCIe NIC, the most likely cause is that the NIC is incompatible with the operating system.

Even if the NIC is properly installed physically, it may not function unless the correct drivers are available and compatible with the OS. Incompatibility can prevent the OS from detecting or properly initializing the NIC, leading to a failure in network recognition or connectivity.

Why Other Options Are Incorrect:

B. The NIC is not connected to a switch:This would prevent network communication but would not stop the server from recognizing the NIC itself. Device recognition happens internally, regardless of network connection.
C. The server's RAM is full: Even with limited RAM, the server should still detect hardware components like NICs. Full RAM might impact performance but doesn’t typically prevent device recognition.
D. The power supply is too strong: Power supplies deliver what is needed, not excess power. A higher-rated PSU doesn’t harm components. Hardware detection issues aren’t caused by a power supply being too strong.
