Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Remote Attestation.
Why this is correct
Remote attestation is the mechanism to verify code integrity in a TEE.
- ✗
Encrypted Page Tables.
Why it's wrong here
This provides memory isolation, not integrity verification.
- ✗
Hardware Root of Trust (RoT).
Why it's wrong here
RoT is the foundation, but attestation provides the verification capability.
- ✗
Signed firmware updates.
Why it's wrong here
This ensures the platform is secure, but doesn't attest to the app state.
