B doesn’t affect relationship types, so it’s not the answer.

A is not the issue; custom fields can be changed.

Wait, are you sure about that? I thought null records could be a reason too.

C is definitely the reason. Roll-up summary fields can’t exist with lookup relationships.

I thought the organization-wide defaults could affect field types, but I’m not confident that’s the main reason in this scenario.

I practiced a similar question where the relationship type couldn't be changed due to roll-up summaries. Could that be the case here?

I’m not entirely sure, but I think if there are null values in the master field, that might prevent the change too.

I remember that changing a master-detail to a lookup can be tricky, especially if there are roll-up summary fields involved.

Alright, let's do this. I'm pretty confident I can figure this out. I just need to make sure I understand the requirements correctly.

This seems like a pretty straightforward question. The Service Provider Admin Portal and the vCloud API are the two options that make the most sense for creating Provider VDCs. I'm feeling pretty confident about this one.

I remember practicing questions about HIDS before, but it seems more about detecting than blocking, right? So maybe it's not that one.

I'm pretty confident it uses IP addresses and possibly protocol IDs, like we discussed in class.
