CompTIA Network+ (N10-007) — Question 659

Which of the following should be performed to verify that unnecessary services are disabled on all switches in an environment?

Answer options

• A. Packet capturing
• B. Port scanning
• C. Log scanning
• D. Baseline review

Correct answer: B

Explanation

Port scanning is the correct choice because it actively checks which services are running on a device, helping to identify any unnecessary services that may be enabled. Packet capturing and log scanning do not specifically target the status of services, and a baseline review typically involves comparing current configurations to a known good state rather than actively discovering services.
