Telnet www.example.com 80 -
Which of the following actions is the administrator performing?

Answer options

• A. Grabbing the web server banner
• B. Logging into the web server
• C. Harvesting cleartext credentials
• D. Accessing the web server management console

Correct answer: A

Explanation

The correct answer is A because using Telnet to connect to port 80 typically retrieves the web server banner, which provides information about the server. Options B, C, and D are incorrect as Telnet is not being used for logging in, credential harvesting, or accessing management interfaces in this context.
