Wait, can chmod really lock an account?

No way, userdel deletes the account, not just locks it!

I vaguely recall that lock is a command, but I don't think it's the one used for locking accounts. I guess I'll lean towards usermod as well.

I feel like chmod is more about changing permissions, so it can't be the answer. I might go with usermod, but I need to double-check.

I remember practicing a question about locking accounts, and I think it was definitely not userdel since that deletes the user.

I think the command to lock a user account is related to usermod, but I'm not completely sure if it's the right option here.

I think the answer is B, usermod. That command allows you to modify user account settings, including locking the account, without deleting anything. I'm pretty confident in that one.

The lock command sounds like it might be the right answer, but I'm not 100% sure if that's the Linux-specific command for locking a user account. I'll have to double-check the options.

Hmm, I'm a bit confused on this one. I know there are commands to lock user accounts, but I'm not sure which one is the right answer here. I'll have to think it through carefully.

I'm pretty sure the answer is B. The usermod command can be used to lock a user's account without deleting any files or data.

B) usermod is the way to go. It's like putting a padlock on the user's account without touching their stuff. Elegant!

Gotta be B) usermod. Wouldn't want to accidentally delete someone's files just to lock them out, you know?

Hmm, I'm torn between B) usermod and C) userdel. Userdel might be a bit overkill, but it's a sure-fire way to keep them out.

Userdel does seem a bit extreme. Maybe try usermod first and see if that does the trick.
