Which tool includes a script that performs the basic enumeration of any open port?

• A. SuperEnum
• B. RPCScan
• C. Dig command
• D. NSLookup

Answer: (B)

Port enumeration means probing a host to discover which ports are open and what services are listening on them. A tool that includes a script designed to perform basic enumeration of any open port is crafted to quickly reveal these reachable ports and their services, giving you a practical snapshot of how the host is exposed. RPCScan fits this role because it’s built to identify RPC-related services across Windows networks and enumerate the endpoints those services expose. Its workflow centers on scanning for open ports and then listing what services respond, effectively providing a basic port-enumeration pass. This makes it well-suited for quickly seeing which ports are open and what’s listening there. SuperEnum, by contrast, targets information about users, groups, and permissions rather than network ports. Dig and NSLookup are DNS query tools and do not perform port scans or port enumeration.
