  B.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.

  A.It executes successfully and the CREATE TABLE privilege is revoked from C # # A_ADMIN in root only.

  B.It fails and reports an error because the CONTAINER=ALL clause is not used.

  C.It excludes successfully and the CREATE TABLE privilege is revoked from C # # A_ADMIN in root and all PDBs.

  D.C.It excludes successfully and the CREATE TABLE privilege is revoked from C # # A_ADMIN in root and all PDBs.D.It fails and reports an error because the CONTAINER=CURRENT clause is not used.

  E.It executes successfully and the CREATE TABLE privilege is revoked from C # #A_ADMIN in all PDBs.
