A security administrator suspects there may be unnecessary services running on a server. Which of the following tools will the administrator MOST likely use to confirm the suspicions?
Correct Answer: A
Nmap, or Network Mapper, is a network scanning and security auditing tool that is commonly used to discover and map network resources, such as servers and devices, and to identify the services running on those resources. It can be used to scan a single host or a range of hosts to determine which ports are open and which services are running on those ports. This information can be used to identify services that may be unnecessary or potentially insecure, and to take appropriate action to mitigate any security risks. In this case, the administrator can use Nmap to scan the server and confirm whether there are any unnecessary services running on it.
