No way, I don't think that's how it works.

I thought overlay traffic was encrypted by default?

Definitely not, it should be --with-secure.

I recall that overlay networks can be encrypted, but I don't think this command alone guarantees it. I need to double-check the documentation.

I practiced a question similar to this, and I believe the correct way to ensure encryption is through a specific network configuration, not just a command flag.

I'm not entirely sure, but I feel like `--secure` isn't a valid option for Docker service creation. It sounds familiar, though.

I think the command is missing the right flag for encryption. I remember something about using `--with-registry-auth` for secure connections.

Okay, I think I've got this. The key is that the emails need to be private and not publicly accessible. That rules out a few options and points me towards Distributed Sending.

Option B looks interesting, but I'm not sure if creating individual images and importing them is the best approach. The question specifically mentions a "lift and shift" migration, so I think option C is the way to go.

Assigning an application to a group seems like the way to go here. That should make it easy to manage the 1,000 users in the Sales department.

I'm a bit confused by the wording here. Does "service inventory" mean something specific in this context? I'll need to make sure I understand that term before answering.
