Which two statements are true?

You support a three-instance, policy-managed, multitenant RAC database CDB1 with two PDBs PDB_1 and
PDB_2.
It runs on an eight-node cluster and a serverpool prod_pool has three servers.
Examine these commands executed on HOST01:
$ srvctl add service –db CDB1 –pdb PDB_1 –service HR –serverpool prod_pool
$ srvctl start service –db CDB1 –service HR
$ srvctl stop service –db CDB1 –service HR
Which two statements are true?

A.
HR is uniformly managed across all instances in prod_pool.

B.
srvctl stop service only closes PDB_1 in the instance on HOST01.

C.
srvctl stop service closes PDB_1 on all CDB1 instances.

D.
srvctl stop service prevents logins for HR only to CDB1 on HOST01.

E.
srvctl stop service prevents logins to any instance of CDB1 using service HR.

F.
HR is available on a single instance of prod_pool.
