Question 1:

• Correct answer: C — test (e.g., test security-policy-match).

• Explanation: The test CLI command simulates traffic through the firewall and reveals exactly which elements would be triggered—Security policy rule, NAT translation, static route, or PBF rule—for a given source/destination/service.

Question 6:
Question 6 asks which agreement type defines the time frame in which a vendor needs to respond. The correct answer is:

• Answer: B — SLA (Service Level Agreement)

• Quick tip: In cases with class imbalance, you might also look at precision, recall, or F1-score, but for this question, accuracy is the i

• Answer: C — linkage to business area objectives.

Why this is the most important:

• Senior management cares about how security supports business goals. Linking the governance process to business objectives shows how security enables value, not just protects assets.
• It aligns risk management with business priorities (revenue, availability, regulatory requirements), helping secure funding and sponsorship.

Why the other options are less critical as the sole focus:

• Knowledge required to analyze each issue: important for depth, but not what senior management needs to judge governance effectiveness.
• Information security metrics: useful, but only meaningful when tied to business objectives; metrics without context may misrepresent value.
• Baseline against which metrics are evalua
