Exam CV0-003 topic 1 question 318 discussion

It is D. If it was the firewall it would time-out and block the connection so it would be unreachable. An error being generated from the device suggests this is an issue with remote device itself. Not having the right version of SSH or having the key in the wrong key storage would cause this issue.

It's A. D would cause an authentication error. A is something I would most likely expect with a connection issue

If the administrator was able to log in to the remote server, it implies that port 22 is open and SSH is functioning correctly. Therefore, the issue is likely not with the firewall settings. Option D, “Ensuring the private key was properly imported”, could indeed be the next step. If the administrator is trying to establish a connection using key-based authentication, any issues with the private key (such as it not being properly imported or not being in the correct location) could prevent the connection.

If the daemon is running and you're able to log in remotely, it's likely that port 22 is already open. If the private key is not correctly imported or configured, the connection attempt could fail, leading to issues such as the daemon not appearing to run correctly. Verifying and ensuring that the private key is correctly imported and configured would address potential authentication issues.

22 is the default port for KVM. The rest are possible but unlikely to be the first thing to check.
