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

Question

Options

• AYou can unplug a PDB from a development CDB and plug it into a production CDB, which allows
• BYou can consolidate shared database memory by combining multiple PDBs in a single CDB.
• CPatching individual PDBs requires the same amount of time as patching individual databases.
• DConsolidating separate databases into a single CDB requires the same amount of storage
• EIn multitenant architecture, a PDB behaves the same as a non-CDB as seen from a client

Explanation

By design, you can quickly unplug the PDB from a CDB and then plug this PDB into different CDB. The implementation technique for plugging and unplugging is similar to the transportable tablespace technique. The process of consolidating data from multiple databases into one database on one computer is known as database consolidation. Starting in Oracle database 12c, the oracle multitenant option, enables you to consolidate data and code without altering existing schemas or applications. By consolidating hardware and sharing database memory and files you reduce costs for hardware, storage, availability and labor. For example, 100 PDBs on single server share one database instance and one set of database files, thereby requiring less hardware and fewer personnel. A PDB is a portable collection of schemas, schema objects and non schema objects that appears to an Oracle Net client as a non-CDB. All Oracle databases before oracle database 12c were non
