考题 Which two statements are true concerning the Resource Manager plans for individual pluggabledatabases (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.
