Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 411

An engineer is trying to securely connect to a router and wants to prevent insecure algorithms from being used. However, the connection is failing. Which action should be taken to accomplish this goal?

Answer options

• A. Generate the RSA key using the crypto key generate rsa command.
• B. Configure the port using the ip ssh port 22 command.
• C. Enable the SSH server using the ip ssh server command.
• D. Disable telnet using the no ip telnet command.

Correct answer: A

Explanation

The correct answer is A, as generating an RSA key is essential for establishing a secure SSH connection. Options B and C may help with the setup but do not directly ensure the use of secure algorithms. Option D, while it enhances security by disabling telnet, does not address the connection issue related to insecure algorithms.
