CompTIA Server+ (SK0-004) — Question 45

A new version of the primary OS used by a company has been released. Due to some significant changes in the OS, a system administrator wants to see which remotely accessible services are enabled by default to access the security risk prior to upgrading to the new version. Which of the following utilities should the administrator use?

Answer options

• A. Cipher program
• B. Port scanner
• C. Telnet client
• D. Packet sniffer

Correct answer: B

Explanation

The correct answer is B, the port scanner, as it is specifically designed to identify open ports and services on a network, helping the administrator assess security risks. The Cipher program is used for encryption, the Telnet client is primarily for connecting to remote servers, and the Packet sniffer captures data packets but does not specifically identify enabled services.
