What does a TPM provide on a server?
Why B is the answer
Hardware-backed keys and platform measurements
A Trusted Platform Module supports secure and measured boot.
In detail
- A TPM supports secure and measured boot.
- It supports secure and measured boot.
Use case
An illustrative scenario, not a real incident.
A server stores keys in its TPM, and measures its boot.

Why the other options are wrong
- A. A cooling control loop for the GPU tray
- It does not control cooling.
- C. Extra GPU memory for very large models
- It adds no GPU memory.
- D. A faster network path for storage traffic
- It is not a network path.
