The correct answer is B, Port scanning.
Port scanning is the process of scanning a network to find open ports and services that are running on those ports. By performing port scanning on all the switches in an environment, one can verify that unnecessary services are disabled. This is because if a service is disabled on a switch, its associated port will be closed, which means that it will not show up during a port scan.
Packet capturing, on the other hand, is used to capture and analyze network traffic, which is not directly related to verifying that unnecessary services are disabled on switches.
Log scanning involves analyzing log files for suspicious activity, which can be useful for detecting security breaches, but it is not specifically aimed at verifying that unnecessary services are disabled on switches.
Baseline review involves comparing the current state of a network to a previously established baseline to identify changes and potential issues, but it does not specifically address unnecessary services on switches.
Port scanning is the best option among the given choices as it directly checks the status of the ports associated with the services and can detect if a service is enabled or not.
