CompTIA XK0-005 Exam - Topic 4 Question 55 Discussion

Actual exam question for CompTIA's XK0-005 exam

Question #: 55
Topic #: 4

A systems administrator creates a public key for authentication. Which of the following tools is most suitable to use when uploading the key to the remote

servers?

Ascp

Bssh-copy-id

Cssh-agent

Dssh-keyscan

Show Suggested Answer

Suggested Answer: B

The best tool to use when uploading the public key to the remote servers is B. ssh-copy-id. This tool will copy the public key from the local computer to the remote server and append it to the authorized_keys file, which is used for public key authentication. This tool will also create the necessary directories and files on the remote server if they do not exist. The other tools are either not suitable or not relevant for this task. For example:

A . scp is a tool for securely copying files between hosts, but it does not automatically add the public key to the authorized_keys file.

C . ssh-agent is a tool for managing private keys and passphrases, but it does not upload the public key to the remote server.

D . ssh-keyscan is a tool for collecting public keys from remote hosts, but it does not upload the public key to the remote server.

Wait, can you use ssh-agent for this? Seems off.

ssh-copy-id is the best choice, no doubt!

ssh-keyscan is just for scanning, not uploading keys!

I thought scp was the way to go?

Definitely ssh-copy-id for this!

I vaguely recall something about ssh-keyscan, but I don't think it uploads keys either. It might just gather them.

I feel like ssh-agent is more about managing keys rather than uploading them, so it can't be the answer.

I remember practicing with scp for file transfers, but I don't think that's the right tool for this question.

I think the answer might be ssh-copy-id since it specifically mentions uploading keys, but I'm not entirely sure.

Okay, let me think this through step-by-step. We need to upload a public key, so tools like scp and ssh-agent aren't quite right. ssh-keyscan is more for scanning for host keys, not uploading your own. That leaves ssh-copy-id as the best option here. I'll go with that.

Ah, I remember this from the lab exercises we did. The tool that's most suitable for uploading a public key to remote servers is ssh-copy-id. It's designed specifically for that purpose, so I'm going with option B.

Hmm, I'm a bit unsure about this one. I know we covered public key authentication in class, but I can't quite remember the specific tool used for uploading the key. I'll have to think this through carefully.

This looks like a straightforward question about the best tool to use for uploading a public key to remote servers. I'm pretty confident I know the answer, but I'll double-check the options just to be sure.
