In which circumstance would a penetration tester perform an unauthenticated scan of a target?

In which circumstance would a penetration tester perform an unauthenticated scan of a target?

• when user credentials were not provided
• when the number of false positive vulnerability reports is not required
• when time is limited and faster scans are required
• when only targets with UDP services are to be scanned

Explanation: Unauthenticated vulnerability scans do not use credentials to scan a target, so they are more likely to be used when a user or root-level credentials are unavailable or unknown.
