Troubleshooting and Maintaining Cisco IP Networks (TSHOOT, legacy) — Question 7

An engineer is attempting to configure a secure connection to a device. During testing, the login is not working. Which statement describes the root cause?

Answer options

• A. Only SSHv1 is allowed and you are trying to configure SSHv2
• B. Domain name has been configured
• C. The transport input ssh command is missing
• D. The old RSA key pair needs to be deleted first C

Correct answer:

Explanation

The correct answer is A because if only SSHv1 is allowed on the device, attempting to configure SSHv2 will result in a login failure. Option B is irrelevant as domain name configuration does not directly affect SSH login. Option C indicates a missing command, but that alone wouldn't rule out all secure connections. Option D is incorrect as the existence of an old RSA key pair does not prevent SSH authentication.
