You work as a systems technician at Certkiller .com. You have just installed an additional processor in a multiple processor system. Upon booting the system, you discover that the new processor is not recognized. What is the MOST probable cause of the problem?

A.
The processor is faulty.

B.
The system BIOS must be updated.

C.
The operating system must be configure for SMP.

D.
The stepping on the new processor is not the same as the existing processors.

Explanation:
The operating system must be configured for using Symmetrical Multi-Processing (SMP). Installing an additional processor in a multiprocessor motherboard without properly configuring the operating system may result in the system ignoring the additional processor.
Incorrect
Answers:
A: The new processor may be faulty but this is unlikely.
B: It is unlikely that the BIOS on a multiprocessor motherboard needs to be updated to support an additional CPU.
D: The stepping on the new processor might not be the same as the older processors but this would not prevent the new processor from being recognized.
