No way, I think it needs a different flag.

I thought it would be read-write by default?

I feel confident that this command mounts the directory correctly, but I might second-guess myself on the read-only part.

I'm a bit confused; does the 'ro' really ensure it's read-only? I thought it could still be modified somehow.

I remember practicing a similar question, and I believe the ':ro' at the end is what makes it read-only.

I think the command looks correct for mounting in read-only mode, but I'm not entirely sure about the syntax.

Hmm, I'm a bit unsure about this one. I know we need to set some parameters to enable soft delete, but I'm not sure which specific ones are required.

Okay, I think I've got a good handle on this. Based on the need to group the information logically and allow the agents to take different actions, I'm going to go with FlexCards. The dynamic layout and built-in actions seem like they'd be a great fit for this use case.

I'm confident I know the answer to this one. A service facade is used to decouple the service architecture, so the correct answer is True.
