A cloud security analyst performs a vulnerability scan on a web application server across all staging environments. According to the vulnerability scan, the web content featured on the server in the s

A penetration test plan involves simulating attacks to find exploitable vulnerabilities, which is not appropriate for validating a false positive claim.

A vulnerability test plan describes how to identify vulnerabilities, not how to confirm that a previously identified one is a false positive.

A user acceptance test plan focuses on verifying that the application meets end-user business requirements, rather than validating infrastructure configurations or security scan results.

A smoke test plan focuses on ensuring the core functionality of the application in the staging environment is intact and operational, which helps confirm that the reported vulnerability (web content on C:\) does not prevent the application from running as expected in this non-production stage. This basic functional verification supports the analyst's claim that the vulnerability scan result is a false positive for the staging environment's operational readiness.
