D seems plausible, adding more content could happen.

Definitely not A, that sounds wrong.

Wait, does that mean the tape gets ejected after the first use?

Kenneth 12 months ago

Nah, I disagree. It should replace the contents with the next file.

I think it will just restore the contents again.

I have a hunch that running it again would add more content from the tape, but I’m not completely confident. I think I need to review how tar works with tape drives.

I recall that running the command again could replace the contents of /opt with something else from the tape. But I can't remember if it would be the next file or just the same one.

I'm not entirely sure, but I feel like the contents of /opt will just be restored again. I practiced a similar question, and it seemed like that was the case.

I think if the command is run again, it might give an error about the tape being ejected. I remember something about tape drives not keeping data after extraction.

I'm a bit confused by the wording here. Does "flex mode" mean the system decides where to store the data, or that all data is stored in the generated MDG tables? I'll have to re-read the options.

This is a straightforward question about digital signatures. I'm pretty confident I can answer this correctly.

Hmm, this is a tricky one. I'm not entirely sure which option poses the greatest risk. I'll need to think through each of the scenarios carefully to determine which one is the most concerning.

This question seems straightforward, but I want to make sure I understand the key details before answering.
