Hmm, I'm not sure about this one. I feel like I need to go back and review the documentation on GRD and how it works in a RAC environment. Anyone else feeling a bit overwhelmed?

Exactly. Now, for options D and E, I'm a bit unsure. They both mention the GRD Enqueue Resource master metadata being held in either the large pool or the shared pool. I'm not sure which one is correct.

Yeah, I agree. Some of these statements seem quite technical and nuanced. We'll need to really think through each one carefully to determine which ones are true.

That makes sense. And I think option C is also true - 'Clustered ASM has GRD resources distributed among all ASM instances.' The GRD is used in the Clustered ASM environment as well, right?

This question seems to be covering a lot of specific details about the Global Resource Directory (GRD) in Oracle 19c RAC and Clustered ASM. It's going to require a good understanding of these concepts to answer it correctly.

You're right, I think option B is more accurate. It says 'Shadow GRD resources may exist in more than one database instance for a resource.' This seems to align with the idea of the GRD being distributed across instances.

Okay, let's start by looking at the first option, A. It says 'Only one GRD shadow resource may exist for an Enqueue Resource.' I'm not sure about this one, but I think it might be false. Doesn't the GRD allow for multiple shadow resources?

Agreed, this is a very detailed and nuanced question. I think we'll need to carefully consider each of the answer options and how they relate to the GRD in the different environments.

This question seems quite technical and specific to the Global Resource Directory (GRD) in Oracle 19c RAC and Clustered ASM. I'm not sure how familiar I am with the details, but let's see if we can work through it together.
