Wait, is the GRD a real thing or did they just make that up to confuse us? Either way, I'm getting a headache just thinking about it.

D? Really? Large pool? Nah, man, the shared pool is where it's at. I'm sticking with E and G.

I believe C is true as well, Clustered ASM does have GRD resources distributed among all ASM instances.

B, C, and F seem correct to me. The GRD resources are distributed among the instances in both RAC and Clustered ASM.

I think B is true because shadow GRD resources can exist in multiple instances.
