Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Confidential
Why this is correct
Encryption at rest and in transit is the prescribed handling control for the Confidential classification, matching the stem's stated requirement exactly. Confidential data demands the strongest protective measures, whereas lower tiers such as Public or Internal do not mandate encryption in both states.
- ✗
Restricted/Top Secret
Why it's wrong here
Restricted/Top Secret is a higher tier than Confidential, reserved for data whose compromise causes severe harm and which typically demands additional controls beyond encryption, such as strict need-to-know access. It overstates the stem's stated Confidential classification.
- ✗
Internal/Private
Why it's wrong here
Internal/Private covers data whose exposure is limited to staff but which does not demand mandated encryption controls. It would fit routine internal documents, whereas the stem's explicit Confidential label and encryption requirement place the data in a higher tier.
- ✗
Public
Why it's wrong here
Public data carries no confidentiality obligation, so encryption at rest and in transit is not mandated for it. The label is tempting because classification schemes always include it, but it applies to openly shareable material such as published marketing content, not Confidential data.
