I agree with Vivan, B doesn't sound right at all.

C is correct, you create a domain with 'CREATE DOMAIN'.

Wait, do you really need both input and output functions for a domain?

I think B is a bit off, domains aren't really a namespace.

A domain can definitely be used as a column type.

I remember that a domain can be used as a column type, so D should be correct, but I'm not completely confident about the others.

I practiced a similar question where we had to identify incorrect statements about domains, and I think A is definitely correct.

I'm not entirely sure, but I feel like option E might be incorrect too. I don't recall needing both functions to define a domain.

I think option B sounds a bit off; I remember domains being more about data types rather than a namespace.

This seems like a tricky question. I'll need to carefully consider the pros and cons of decentralized risk registers.

Okay, let's see. The question mentions a full mesh of mesh-SDPs within each metro, and a spoke-SDP between PE-C and PE-B. That's an important detail.

Hmm, I'm a bit unsure about this one. I'll have to review my notes on malicious intermediary attacks to make sure I understand the possible outcomes.

This question seems straightforward. Encryption is challenging because it hides the contents of network traffic, making it harder for security monitoring tools to analyze and detect threats.

Wait, so are we supposed to select the two incorrect statements, or the two correct ones? This domain debate is starting to feel a bit like a domain name dispute!

I heard the exam committee was really dominating the question selection process this year. Looks like they wanted to make sure we knew our domains inside and out!

Yep, B and E are the ones to go with. Domains are all about data types, not namespaces or input/output functions. Though I do wonder if the person who wrote this question was just testing our domain knowledge, or if they were trying to trip us up with some SQL trivia.

Hmm, I'm not sure about option A. Can you really add a default value and constraints to a domain? That seems like it would be more of a table-level thing.

I agree with Leatha. B and E seem to be the incorrect statements here. Domains are not related to namespaces or databases, and you don't need both input and output functions.
