Explanation
Policies (CNSS issuances) are the documents that establish criteria and assign responsibilities - they set the high-level "what must be done and by whom" framework for national security systems security.
Why the distractors are wrong:
- A. Advisory memoranda are informational and non-binding - they provide guidance or awareness but do not assign responsibilities.
- B. Directives mandate specific actions or compliance requirements but focus on directing behavior rather than establishing criteria and assigning roles.
- C. Instructions provide the operational "how-to" - step-by-step implementation details for carrying out policy requirements.
Memory tip: Think of the hierarchy as P-D-I-A (top to bottom): Policies set the rules and ownership → Directives mandate action → Instructions explain how → Advisory memos just inform. If a question mentions "criteria" + "responsibilities" together, that's policy-level language.
