Question 1

Which two statements are true concerning the Resource Manager plans for individual pluggable databases (PDB plans) in a multitenant container database (CDB)? (Choose two.)

If no PDB plan is enabled for a pluggable database, then all sessions for that PDB are treated to an equal degree of the resource share of that PDB.
In a PDB plan, subplans may be used with up to eight consumer groups.
If a PDB plan is enabled for a pluggable database, then resources are allocated to consumer groups across all PDBs in the CDB.
If no PDB plan is enabled for a pluggable database, then the PDB share in the CDB plan is dynamically calculated.
If a PDB plan is enabled for a pluggable database, then resources are allocated to consumer groups based on the shares provided to the PDB in the CDB plan and the shares provided to the consumer groups in the PDB plan.

Correct answer: AE

Explanation:

A: Setting a PDB resource plan is optional. If not specified, all sessions within the PDB are treated equally.* In a non-CDB database, workloads within a database are managed with resource plans. In a PDB, workloads are also managed with resource plans, also called PDB resource plans. The functionality is similar except for the following differences:/ Non-CDB Database Multi-level resource plans Up to 32 consumer groups Subplans / PDB Database Single-level resource plans only Up to 8 consumer groups (not B) No subplans

A: Setting a PDB resource plan is optional. If not specified, all sessions within the PDB are treated equally.

In a PDB, workloads are also managed with resource plans, also called PDB resource plans.

The functionality is similar except for the following differences:

/ Non-CDB Database

Multi-level resource plans

Up to 32 consumer groups

Subplans

/ PDB Database

Single-level resource plans only

Up to 8 consumer groups

(not B) No subplans

Question 2

You use a recovery catalog for maintaining your database backups.

You execute the following command:

$rman TARGET / CATALOG rman / cat@catdb

RMAN > BACKUP VALIDATE DATABASE ARCHIVELOG ALL;

Which two statements are true? (Choose two.)

Corrupted blocks, if any, are repaired.
Checks are performed for physical corruptions.
Checks are performed for logical corruptions.
Checks are performed to confirm whether all database files exist in correct locations
Backup sets containing both data files and archive logs are created.

Correct answer: BD

Explanation:

B (not C): You can validate that all database files and archived redo logs can be backed up by running a command as follows:RMAN> BACKUP VALIDATE DATABASE ARCHIVELOG ALL; This form of the command would check for physical corruption. To check for logical corruption, RMAN> BACKUP VALIDATE CHECK LOGICAL DATABASE ARCHIVELOG ALL; D: You can use the VALIDATE keyword of the BACKUP command to do the following:Check datafiles for physical and logical corruption Confirm that all database files exist and are in the correct locations. Note:You can use the VALIDATE option of the BACKUP command to verify that database files exist and are in the correct locations (D), and have no physical or logical corruptions that would prevent RMAN from creating backups of them. When performing a BACKUP...VALIDATE, RMAN reads the files to be backed up in their entirety, as it would during a real backup. It does not, however, actually produce any backup sets or image copies (Not A, not E).

B (not C): You can validate that all database files and archived redo logs can be backed up by running a command as follows:

RMAN> BACKUP VALIDATE DATABASE ARCHIVELOG ALL;

This form of the command would check for physical corruption. To check for logical corruption,

RMAN> BACKUP VALIDATE CHECK LOGICAL DATABASE ARCHIVELOG ALL;

D: You can use the VALIDATE keyword of the BACKUP command to do the following:

Check datafiles for physical and logical corruption

Confirm that all database files exist and are in the correct locations.

Question 3

Which three statements are true concerning the multitenant architecture? (Choose three.)

Each pluggable database (PDB) has its own set of background processes.
A PDB can have a private temp tablespace.
PDBs can share the sysaux tablespace.
Log switches occur only at the multitenant container database (CDB) level.
Different PDBs can have different default block sizes.
PDBs share a common system tablespace.
Instance recovery is always performed at the CDB level.

Correct answer: BDG

Explanation:

B:A PDB would have its SYSTEM, SYSAUX, TEMP tablespaces. It can also contain 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 recoveryThe automatic application of redo log records to uncommitted data blocks when a 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.
