Which statement describes Finger?

• A. It is used to manage DNS records.
• B. It is used to gather information about users on a network.
• C. It is used to monitor CPU usage.
• D. It is used to encrypt data.

Answer: (B)

Finger is a simple information-gathering service used to retrieve details about user accounts on a remote host. It allows you to learn who is logged in, their login name, and often additional publicly exposed details like real names or idle time. This makes it a reconnaissance tool for collecting information about users on a network, which is exactly what the correct statement describes. It is not used to manage DNS records, monitor CPU usage, or encrypt data—those fall outside Finger’s purpose.
