Understanding Cisco Cybersecurity Fundamentals (SECFND, legacy) — Question 57

Which situation indicates application-level whitelisting?

Answer options

• A. Allow everything and deny specific executable files.
• B. Allow specific executable files and deny specific executable files.
• C. Writing current application attacks on a whiteboard daily.
• D. Allow specific files and deny everything else.

Correct answer: D

Explanation

The correct answer, D, defines application-level whitelisting by allowing only specific files while blocking everything else. Option A allows everything with restrictions on certain files, which does not align with whitelisting. Option B also allows certain files while denying others, but does not embody the principle of whitelisting. Option C is unrelated to whitelisting and focuses on tracking vulnerabilities.
