Definitely not, you need --read-only flag.

No way, that's not how you set read-only.

Yes, but the syntax is off.

I feel like I’ve seen this before, and I think the answer is 'No' because of the syntax issue with read-only.

I’m pretty confident that the volume flag '-v' is correct, but I can't recall if the read-only part is set up right.

I remember a similar question where we had to specify read-only differently. I think it might be 'ro' instead of '--mode readonly'.

I think the command is almost right, but I’m not sure if '--mode readonly' is the correct syntax for read-only.

Whoa, this is tricky. I'm going to need to draw out some examples to work through the different scenarios and make sure I understand what's happening.

Okay, I think I've got this. Determining staffing requirements based on projected volume and service levels seems like the core step in the resource-scheduling process. I'll go with option A.

Okay, I've got a strategy in mind. I think creating a DAG in Cloud Composer would be the best way to schedule and monitor these workflows. That way, I can easily orchestrate the different jobs and get a clear view of their execution.
