Seems risky to rely on self-signed, though.

No way, self-signed can work just fine for this!

I thought only external CAs were valid for security compliance?

Totally agree, external CA isn't necessary for internal services.

Self-signed certificates can be used internally.

This seems similar to a case we discussed in class, where we concluded that internal services could use self-signed certificates without issues.

I feel like the specialist is being too strict; I thought self-signed certificates were fine as long as both services trust them.

I think we practiced a question where self-signed certificates were acceptable for internal services, but I can't recall the specifics.

I remember studying that self-signed certificates can be used for internal communications, but I'm not sure if they meet all security requirements.

This is a tricky one. The security specialist's statement seems definitive, but I'm not sure if that's the only correct answer. I'll need to review my notes on certificate authorities and organizational boundaries to decide.

Okay, I've got a strategy here. The key is to focus on the security requirement of message-layer protection. Since the services are internal, self-signed certificates could potentially fulfill that requirement. I'll weigh the pros and cons and make my best judgment.

Hmm, I'm a bit unsure about this one. The question mentions that the services are only used within the organizational boundary, so I'm not sure if that changes the security requirements. I'll need to think this through carefully.

This seems like a straightforward question about the use of self-signed certificates versus certificates signed by a CA. I think I have a good understanding of the concepts, so I'll carefully read through the details and make my choice.

I'm a bit confused on this one. The requirements seem to conflict a bit - 24-hour availability but also the ability to control failover. I'm not sure if any of these options fully meet all the criteria. I might need to do some more research on disaster recovery solutions to figure out the best approach.

I'm a bit unsure about this one. The options mention different maintenance menus, but I'm not sure which one specifically shows the software release details for all the nodes. I'll have to think this through carefully.

Hmm, I'm hesitant, but I feel like **D - Visibility/Graphic Overrides** could also relate to controlling boundaries in plan views.

I'm pretty sure it's not option 'A', because I remember there should be a 'type' like 'text/css' in it too.

Ugh, I hate questions like this that are so specific and technical. I'm going to have to guess on this one since I don't have a good intuitive feel for the right bend radius. Maybe I'll just go with C since it's the middle option.
