RFC 9334 Quiz

**Explanation:** A: The Attester produces Evidence containing claims about its Target Environment. B: The Verifier consumes and appraises Evidence. C: The Relying Party consumes Attestation Results for its decision.

**Explanation:** A: A role does not create the environment it is appraising. B: RATS does not define OAuth code issuance as the Verifier's output. C: The Verifier applies an Evidence appraisal policy and produces Attestation Results.

**Explanation:** A: The Attester creates Evidence and does not make the Relying Party's acceptance decision. B: The Relying Party evaluates Attestation Results using its result-appraisal policy. C: An Endorser supplies Endorsements used by a Verifier.

**Explanation:** A: The Verifier appraises Evidence while the Relying Party makes its own decision. B: Signature validity does not define the Relying Party's authorization policy. C: An Attestation Result is decision support and can still be unacceptable for a particular use.

**Explanation:** A: The reusable result resembles a passport carried by its holder. B: That flow describes the Background-Check Model more closely. C: Both topological patterns retain the Evidence-appraisal role of a Verifier.

**Explanation:** A: That is characteristic of the Passport Model and is not required here. B: The result returns to the Relying Party for its own appraisal and decision. C: The architecture assigns Evidence appraisal to the Verifier role.

**Explanation:** A: Nonces can support freshness but are not Reference Values. B: Reference Values are inputs to Evidence appraisal, not the final decision. C: They provide comparison material for assessing claims in Evidence.

**Explanation:** A: Timestamps, nonces, or epoch identifiers can connect appraisal to a relevant time window. B: Freshness describes timing and cannot guarantee future state. C: Freshness and source authenticity are separate properties.

**Explanation:** A: Broad disclosure increases privacy risk and may expose security-sensitive state. B: The Attester may need assurance about the Verifier before sending sensitive Evidence. C: Confidential conveyance does not appraise claim correctness.

**Explanation:** A: Self-asserted claims do not perform the architecture's independent appraisal step. B: A positive result is contextual and does not define operation scope. C: This preserves the RATS role separation and prevents attestation from silently becoming universal authorization.
