A technician has added another processor to a multi-processor server. When restarting, the server fails to respond. The technician has already verified the model and speed of the processor. Which of t

Whether virtual technology support is active or inactive typically affects the ability to run virtual machines efficiently, but it would not prevent a server from booting with a new processor.

Processor stepping refers to specific revisions or versions of a CPU within the same model family, which can introduce incompatibilities even if the model and speed appear identical. Different steppings often require specific motherboard BIOS updates or microcode, and mismatched steppings in a multi-processor system can prevent the server from booting properly.

Hyper-threading is a feature that allows a single core to handle multiple threads; its enablement status would not prevent a server from booting if the processor itself is incompatible.

L1 cache is an integral part of the processor's architecture, and its 'activity' is not a configurable setting that a technician would troubleshoot as a cause of a server failing to respond after a CPU installation.
