Which three statements represent the benefits of multitenant architecture for database
consolidation?

A.
You can unplug a PDB from a development CDB and plug it into a production CDB, which
allows for easier and more rapid movement of data and code.

B.
You can consolidate shared database memory by combining multiple PDBs in a single CDB.

C.
Patching individual PDBs requires the same amount of time as patching individual databases.

D.
Consolidating separate databases into a single CDB requires the same amount of storage
allocation.

E.
In multitenant architecture, a PDB behaves the same as a non-CDB as seen from a client
connecting with Oracle Net. No client modification is required.
