Which of the following prerequisites should be met before adding a processor to a server? (Select TWO).

The operating system must have built-in support for symmetric multiprocessing (SMP) to effectively detect, configure, and utilize multiple processors for workload distribution.

For stable operation and optimal performance in multi-processor systems, it is generally required that all processors be identical, including having the same step code (revision level), to ensure perfect compatibility and synchronization.

While NUMA (Non-Uniform Memory Access) is a feature beneficial for optimizing memory access in multi-processor systems, it is not a prerequisite for the initial addition of a processor.

It is not a prerequisite that all running processes explicitly support multiple processors; the operating system's scheduler is responsible for distributing single-threaded and multi-threaded processes across available cores.

The operating system must use an SMP (Symmetric Multiprocessing) kernel to properly manage and leverage multiple processors; if it does not, the additional processor would remain unused.
