The correct answer is C. The processors do not match. In a multi-processor server, all CPUs installed must be identical - same model, same stepping, same cache size, and same firmware revision. Even though both processors run at 3.0GHz, the existing CPU has a 1MB cache while the new CPU has a 2MB cache. This mismatch means they…
Question
A company would like to upgrade an old server to a multi-processor box. The server currently has a single 3.0GHz 1Mb cache processor in it with a single empty socket. The only processor that is available from a manufacturer is a 3.0GHz 2Mb cache model. Which of the following is the BEST reason why this upgrade will not work?
Options
- AThe socket size does not match
- BThe cache is from a different manufacturer
- CThe processors do not match
- DProcessors cannot be upgraded after server has been deployed

Explanation
In a multi-processor server, all CPUs installed must be identical - same model, same stepping, same cache size, and same firmware revision. Even though both processors run at 3.0GHz, the existing CPU has a 1MB cache while the new CPU has a 2MB cache. This mismatch means they are different processor models and the system cannot pair them in a symmetric multi-processing (SMP) configuration. The socket type may be compatible (same physical interface), the manufacturer is the same (ruling out choice B), and upgrades are certainly possible after deployment (ruling out choice D). The root cause is simply that the two CPUs are not identical, which is a hard requirement for multi-socket server operation.
