Which two statements are true concerning the Resource Manager plans for individual pluggable databases
(PDB plans) in a multitenant container database (CDB)?
A.
If no PDB plan is enabled for a pluggable database, then all sessions for that PDB are treated to an
equal degree of the resource share of that PDB.
B.
In a PDB plan, subplans may be used with up to eight consumer groups.
C.
If a PDB plan is enabled for a pluggable database, then resources are allocated to consumer groups
across all PDBs in the CDB.
D.
If no PDB plan is enabled for a pluggable database, then the PDB share in the CDB plan is dynamically
calculated.
E.
If a PDB plan is enabled for a pluggable database, then resources are allocated to consumer groups
based on the shares provided to the PDB in the CDB plan and the shares provided to the consumer
groups in the PDB plan.
Explanation:
A: Setting a PDB resource plan is optional. If not specified, all sessions within the PDB are
treated equally.

In a non-CDB database, workloads within a database are managed with resource plans. In a PDB,
workloads are also managed with resource plans, also called PDB resource plans. The functionality is
similar except for the following differences:
/ Non-CDB Database
Multi-level resource plans
Up to 32 consumer groups
Subplans
/ PDB Database
Single-level resource plans only
Up to 8 consumer groups
(not B) No subplans
