Oracle Database 12c: Installation and Administration — Question 2

Identify two correct statements about multitenant architectures.

Answer options

• A. Multitenant architecture can be deployed only in a Real Application Clusters (RAC) configuration.
• B. Multiple pluggable databases (PDBs) share certain multitenant container database (CDB) resources.
• C. Multiple CDBs share certain PDB resources.
• D. Multiple non-RAC CDB instances can mount the same PDB as long as they are on the same server.
• E. Patches are always applied at the CDB level.
• F. A PDB can have a private undo tablespace.

Correct answer: B, E

Explanation

Option B is correct because it accurately describes how multiple PDBs share resources within a CDB in a multitenant architecture. Option E is also correct as patches are indeed applied at the CDB level affecting all associated PDBs. The other options are incorrect because A is too restrictive, C misrepresents resource sharing, D is not allowed in the context of PDB access, and F is inaccurate as a PDB cannot have a private undo tablespace.
