Which term describes a hardware module used for secure key storage and attestation?

• A. NVMe
• B. Backplane
• C. Trusted Platform Module
• D. RAID controller

Answer: (C)

A hardware root of trust that securely stores cryptographic keys and can attest to the system’s state is what this question is about. A Trusted Platform Module is a dedicated hardware crypto processor built to generate, store, and use keys in a way that keeps them isolated from the rest of the system. It can perform cryptographic operations inside the module and provide attestation through platform configuration data, so a remote verifier can confirm the machine booted in a known, trusted state. NVMe is just a storage interface, backplane is the physical interconnect, and a RAID controller manages disk redundancy and performance. The Trusted Platform Module uniquely fits the role of secure key storage plus attestation.
