DB2 and Oracle are both relational, no doubt!

Wait, I thought Redis could be used for relational stuff?

I feel like Redis was mentioned in class as a NoSQL database, so I think that might be the answer here.

I’m a bit confused. I know Oracle and DB2 are definitely relational, but I can't recall if Teradata is also.

I practiced a similar question last week, and I believe Redis is the one that doesn't fit with the others since it's more of a key-value store.

I think I remember that Oracle, DB2, and Teradata are all relational databases, but I'm not completely sure about Redis.

This looks like a straightforward question about securing an API Gateway with Cognito. I think the key is to find the solution that has the least operational overhead, so I'll focus on that.

Okay, let me break this down. The host country supervisor would have the most direct knowledge of the local context, so I don't think that's the answer.

I've got a good feeling about this one. Expanding the number of lanes on a highway is all about increasing supply, which is the opposite of what Transportation Demand Management is trying to achieve. I'm confident that's the right answer.

I'm pretty confident that option D is the one that doesn't make sense. Increasing intrinsic interoperability is not one of the goals of service-oriented computing, so that statement doesn't seem right.
