Not convinced about 4001 being necessary. What’s that for?

Wait, are we sure about 22389? Seems a bit random.

I think port 389 is also essential for directory services.

Definitely need port 443 for secure communication.

I practiced a similar question before, and I think port 8472 is used for VXLAN, which could be important for overlay networks in this scenario.

I’m not entirely sure, but I think port 389 is related to LDAP, which might be necessary for directory services in a cloud pod architecture.

I remember that port 443 is commonly used for secure HTTPS traffic, so it seems like a likely choice for communication between the data centers.

I’m a bit confused about the options, but I feel like we should definitely minimize the number of ports, so I hope we can narrow it down to just two essential ones.

Option C looks interesting - migrating the Snowflake deployment to the same region could simplify things. But I'm not sure if that's the most efficient solution, especially if there are a lot of data to move.

This question seems similar to the practice exams we did, especially about using a vendor-neutral protocol for discovery. Was it LLDP or CDP?

I'm a bit confused by the wording of the question. Is it asking about the manager's role as a trainer specifically, or the overall roles of a manager? I want to make sure I understand the focus before selecting an answer.

I feel like creating intermediate entities is the right step but I'm a bit confused about whether that's always the next move.
