You administer a six-instance, policy-managed, multitenant RAC database CDB1 with three PDBs: PDB_1,PDB_2, and PDB_3.
Server pool prod_pool has a cardinality of three and all six hosts of the cluster are up.
Examine these commands executed on HOST01:

Which two statements are true regarding the AR service? (Choose two.)

A.
AR can fail over to any one of the available CDB1 instances.
B.
AR runs as a singleton service in the server pool prod_pool and the AR service is available in each of the CDB1 instances.
C.
AR can fail over to any other available CDB1 instance in prod_pool.
D.
AR is available only on the CDB1 instance on HOST01.
E.
AR is available on any one available CDB1 instance in prod_pool at any one time.

Re: 1z0-078 topic 1 question 33

CE ; E...one (any) instance from the pool in one time. A...all the instances are not in the prod_pool ( just 3 of them)

Re: 1z0-078 topic 1 question 33

A - true - AR can fail over to any instance (all the instances are in prod_pool)
B - false - AR is singleton service - it can run only on one instance
C - true (all the CDB1 instances run in the prod_pool)
D - false - we do not know if cdb1 instance is running on host01 now
E - false - AR is singleton service - it can run only on one instance at the time
