B:
*A PDB would have its SYSTEM, SYSAUX, TEMP tablespaces.It can also contains other user created tablespaces in it.
*There is one default temporary tablespace for the entire CDB. However, you can create additional temporary tablespaces in individual PDBs.
D:
*There is a single redo log and a single control file for an entire CDB
*A log switch is the point at which the database stops writing to one redo log file and begins writing to another. Normally, a log switch occurs when the current redo log file is completely filled and writing must continue to the next redo log file.
G: instance recovery The automatic application of redo log records to uncommitted data blocks when an database instance is restarted after a failure.
Incorrect: Not A:
*There is one set of background processes shared by the root and all PDBs. -
*High consolidation density. The many pluggable databases in a single 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.
Not C: There is a separate SYSAUX tablespace for the root and for each PDB.
Not F: There is a separate SYSTEM tablespace for the root and for each PDB.
