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.
Explanation:
By design, you can quickly plug a PDB into a CDB, unplug the PDB from the CDB, and then plug this PDB into
a different CDB. The implementation technique for plugging and unplugging is similar to the transportable
tablespace technique.
A PDB is a portable collection of schemas, schema objects, and nonschema objects that appears to an Oracle
Net client as a non-CDB. All Oracle databases before Oracle Database 12c were non-CDBs.
