Suggested Answer: CE 🗳️
The benefits of Oracle Multitenant are brought by implementing a pure deployment choice. The following list calls out the most compelling examples.
* High consolidation density. (E)
The many pluggable databases in a single multitenant container database share its memory and background processes, letting you operate many more pluggable databases on a particular platform than you can single databases that use the old architecture. This is the same benefit that schema-based consolidation brings.
* Rapid provisioning and cloning using SQL.
* New paradigms for rapid patching and upgrades. (D, not B)
The investment of time and effort to patch one multitenant container database results in patching all of its many pluggable databases. To patch a single pluggable database, you simply unplug/plug to a multitenant container database at a different Oracle Database software version.
* (C, not A) Manage many databases as one.
By consolidating existing databases as pluggable databases, administrators can manage many databases as one. For example, tasks like backup and disaster recovery are performed at the multitenant container database level.
* Dynamic between pluggable database resource management. In Oracle Database 12c, Resource Manager is extended with specific functionality to control the competition for resources between the pluggable databases within a multitenant container database.
Note:
* Oracle Multitenant is a new option for Oracle Database 12c Enterprise Edition that helps customers reduce IT costs by simplifying consolidation, provisioning, upgrades, and more. It is supported by a new architecture that allows a multitenant container database to hold many pluggable databases. And it fully complements other options, including Oracle Real Application Clusters and Oracle Active Data Guard. An existing database can be simply adopted, with no change, as a pluggable database; and no changes are needed in the other tiers of the application.

D is also correct. Answer should be C and D.

Why not D too? When you apply to CDB, all its PDBs are patched with it. E seems very strict with the "only" in response
