Question 26

Which four are true about Consolidated Database Replay? (Choose four.)

A.The workload capture and replay servers must run the same operating system (OS).

B.Multiple workload captures from multiple databases can be replayed simultaneously.

C.A subset of the captured workload can be replayed.

D.The number of captured workloads must be the same as the number of PDBs in a multitenant CDB.

E.Multiple replay schedules can be defined for a consolidated replay.

F.A single replay schedules can be defined for a consolidated replay.

G.A superset of the captured workload can be replayed.

Question 27

While performing database backupto tape via the media manager interface, you notice that tape streaming is not happening because RMAN is not sending data blocks fast enough to the tape drive.
Which two actions would you take for tape streaming to happen during the backup?

A.Configure the channel to increase capacity with the rate parameter.

B.Configure a backup policy by using incremental backups.

C.Configure the channel to increase maxopenfiles.

D.Configure backup optimization.

E.Configure the channel to adjust the tape buffer size byusing the 3LKSIZE option.

F.LARGE_POOL.

G.Configure large_pool, if not done already. Alternatively, you can increase the size of

Question 28

Which two components are contained only in CDB$ROOT? (Choose two.)

A.the unified audit trail

B.database links between PDBs in the CDB

C.PDB service names

D.resource manager plans for each PDB in the CDB

E.the default TEMPtablespace for the entire CDB

Question 29

Examine the command:
$expdp SYSTEM FULL=YES DUMPFILE=dpump_dir1:fulll%U.dmp, dpump_dir2:full2% U.dmp, dpump_dir3:full3%U.djnp FILESIZE=400M PARALLEL=3 JOB_NAME=expfull
Which statement is true about the execution of the command?

A.It fails because the log file parameter is not specified.

B.It fails because no absolutepath is specified for the log file and dump file.

C.It succeeds and exports the full database, simultaneously creating three dump files at three different locations, but the total number of dump files can exceed three.

D.It succeeds and exports the full database, simultaneously creating three copies of dump files at three different locations.

Question 30

You want to consolidate databases for the CRM, ERP, and SCM applications by migrating them to pluggable databases (PDBs).
You have already created a test system to support the consolidation of databases in a multitenant container database (CDB) that has multiple PDBs.
What is the easiest way to perform capacity planning for consolidation?

A.capturing the most resource-intensive SQL statements in a SQL Tuning Set on the production system and using the SQL Performance Analyzer on the test system

B.capturing the workload on the production system and using Consolidated Database Replay to replay the workload of all production systems simultaneously for all PDBs

C.capturing the most resource-intensive SQL statements in a SQL Tuning Set on the production system and using the SQL Tuning Advisor on the test system

D.capturing the workload on the production system and replaying the workload for one PDB at a time on the test system
