Oh, this is a tricky one! I'm going to go with B and E. The AR service is a singleton, so it can only be available on one CDB1 instance at a time, but it can fail over to any other available instance in the pool.

Haha, I bet the AR service is like a diva, only performing on one instance at a time! But seriously, I think the correct answers are B and E.

I'm not sure about this one. The question mentions that all six hosts of the cluster are up, so I'm not sure if option D is correct. I'm going to go with B and C.

Great, so we both think options B and C are the correct statements regarding the AR service.

I agree, and option C is also true because AR can fail over to any other available CDBl instance in prod pool.
