Which Command Determines Unnecessary Services on a Network Server?

A network technician recently installed a new server on a network.

The technician must ensure the server does not have any unnecessary services running.

The IP address of the server is 204.211.38.50

Which of the following commands would allow the technician to make this determination?

A.

nmap

B.

pathping

C.

route

D.

nslookup.

A.

The command that would allow the technician to determine whether the server has any unnecessary services running is "nmap".

Nmap stands for "Network Mapper". It is a network exploration and security auditing tool that can be used to identify hosts and services on a network, as well as check for open ports and vulnerabilities.

To use nmap, the technician would need to open a command prompt or terminal and type "nmap 204.211.38.50". This would scan the server at that IP address and provide a report of any open ports or services running on the server.

The technician could then use this report to determine whether there are any unnecessary services running on the server and take steps to disable them if necessary. For example, if the report shows that the server is running a web server but the organization does not require one, the technician could disable the web server to reduce the attack surface of the server.

Pathping, route, and nslookup are all network diagnostic tools, but they would not provide the information needed to determine whether there are any unnecessary services running on the server.
