Which two statements about multitenant architecture are true?
A. Multiple PDBs on a single server need multiple database instances and multiple sets of database files.
B. Although consolidated into a single physical database, PDBs mimic the behavior of non- CDBs.
C. A PDB administrator can use Oracle Flashback or point-in-time recovery to retrieve lost data from a PDB, only by shutting down all the PDBs from the CDB.
D. It is easier to collect performance metrics for many databases in a CDB than individual non- CDB databases.
E. It takes more time to apply a patch to one CDB that holds hundreds of PDBs than to hundreds of non-CDB databases.
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.
Which two items are key for maintaining data consistency in Oracle Database 12c?
A. undo data

B. A multitenant container database (CDB) can have several pluggable databases (PDBs) with different character sets.
C. Oracle recommends that you back up the root. sh script after you complete the installation.
D. Cloning an Oracle home is useful if you are performing multiple Oracle Database Installations.
E. You can stop existing Oracle processes, including the listener and the database running in the Oracle home, before the database software installation.
Which type of file system is NOT valid for storing data files, online redo log files, and control files for a pluggable database?
A. Automatic Storage Management (ASM)
B. OS file system
C. logical volume (LVM)
D. clustered file system
E. RAW
