Q91. Yourdatabase is running in archivelog mode and a nightly backup of the database, along with an autobackup of the control file, is taken by using RMAN. Because of a media failure, the SPFILE and the control files are lost.
Examine the steps to restore the SPFILE and the control file to mount the database:
1. Set D3ID of the target database in RMAN.
2.Start the database instance by using the startup force nomount command in RMAN.
3.Restore the control files from the backup.
4.Mount the database.
5.Restore theSPFILE from the autobackup.
6.Create a PFILE from the recovered SPFILE.
7.Restart the instance in nomount state.
Identify the required steps in the correct order.
A. 1, 2, 5, 3, 6, 4
B. 1, 2, 3, 5, 6, 4
C. 2, 1, 5, 7, 3, 4
D. 2, 1, 5, 6, 7, 4, 3
104. You want to move your existing recovery catalog to another database.
Examine the steps:
1)Export the catalog data by using the Data Pump Export utility in the source database.
2) Create a recovery catalog user and grant the necessary privileges in the target
3) Create a recovery catalog by using the create catalog command.
4)Import the catalog data into the new recovery catalog by using the Data Pump Import
utility in the target database.
5)Import the source recovery catalog schema by using the import catalog command.
6)Connect to the destination database.
7) Connect as catalog to the destination recovery catalog schema.
Identify the option with the correct sequence for moving the recovery catalog.
A. 1, 6, 4
B. 2, 3, 7, 5
C. 1, 2, 6, 4
D. 1, 2, 3, 6, 5
Q92. Examine the command:
SQL>RECOVER DATABASE USING BACKUP CONTROLFILE UNTIL CANCEL;
In which two scenarios is this command required?
A. The current online redo log file is missing.
B. A data file belonging to a noncritical tablespace is missing.
C. All the control files are missing.
D. The database backup is older than the control file backup.
E. All the data files are missing.
Q93. Automatic Undo Management is enabled for your database. You want a user to retrieve metadata and historical data for a given transaction or for transactions in a given time interval.
Which three are prerequisites to fulfill this requirement?
A. Minimal supplemental logging must be enabled.
B. The database must be running in archivelog mode.
C. Flashback Data Archive must be created and the flashback archive administer system privilege must be granted to the user.
D. The flashback any table privilegemust be granted to the user.
E. The select any transaction privilege must be granted to the user.
F. The recycle bin parameter must be set to on.
Q94. Your multitenant container database (CDB) cdb1 that is running in archivelog mode contains two pluggable databases (PDBs), pdb2_1 and pdb2_2, both of which are open. RMAN is connected to the target database pdb2_1.
RMAN> BACKUP DATABASE PLUS ARCHIVELOG DELETE INPUT;
Which statement is true about the execution of this command to back up the database?
A. All data files belonging to pdb2_1 are backed up and all archive log files are deleted.
B. All data files belonging to pdb2_1 are backed up along with the archive log files.
C. Only the data files belonging to pdb2_ are backed up.
D. This command gives an error because archive log files can be backed up only when RMAN is connected to the root database.
Q95. Your database supports an online transaction processing (OLTP) workload in which one of the applications creates a temporary table for a session and performs transactions on it. This consumes a lot of undo tablespace and is affecting undo retention.
Which two actions would you take to solve this problem?
A. Enable temporary undo for the database.
B. Enable undo retention guarantee.
C. Increase the size of the redo log buffer.
D. Enable Automatic Memory Management (AMM).
E. Increase the size of the temporary tablespace.
Q96. Which two statements are true about service creation for pluggable databases (PDBs)?
A. When a PDB is created, a service is automatically started in the instance with the same name as the PDB.
B. The defaultservice that is automatically created by a database at the time of PDB creation can be dropped, provided a new additional service is created.
C. A database managed by Oracle Restart can have additional services created or existing services modified by usingthe srvctl utility for each PDB.
D. Only a common user can create additional services for a PDB.
E. When a PDB is created, a service with the same name as the PDB is created in the PDB.
Q97. You are administering a database that supports data warehousing workload and Is running in noarchivelog mode. You use RMAN to perform a level 0 backup on Sundays and level 1 Incremental backups on all the other days of the week.
One of the data files is corrupted and the current online redo log file is lost because of a media failure.
You want to recover the data file.
Examine the steps involved in the recovery process:
1.Shut down the database instance.
2.Start up the database instance in nomount state.
3.Mount the database.
4.Take the data file offline.
5.Put the data file online.
6.Restore the control file.
7.Restore the database.
8.Restore the data file.
9.Open the database with the resetlog option.
10.Recover the database withthe noredo option.
11.Recover the data file with the noredo option.
Identify the required steps in the correct order.
A. 4, 8, 11, 5
B. 1, 3, 8, 11, 9
C. 1, 2, 6, 3, 7, 10, 9
D. 1, 3, 7, 10, 9
E. 1, 2, 6, 3, 8, 11, 9
Q98. Which statement is true about Enterprise Manager (EM) express in Oracle Database 12c?
A. By default, EM express is available for a database after database creation.
B. You can use EM express to manage multiple databases running on the same server.
C. You can perform basic administrative tasks for pluggable databases by using the EM express interface.
D. You cannot start up or shut down a database instance by using create and configure pluggable databases by using EM express.
E. You can create and configure pluggable databases by using EM express.
Explanation: EM Express is built inside the database.
Note: Oracle Enterprise Manager Database Express (EM Express) is a web-based database management tool that is built inside the Oracle Database. It supports key performance management and basicdatabase administration functions. From an architectural perspective, EM Express has no mid-tier or middleware components, ensuring that its overhead on the database server is negligible.
Q99. Examine the backup requirement for your company:
1) Every Sunday, a backup of all used data file blocks is performed.
2) Every Wednesday and Friday, a backup of all the changed blocks since last Sunday's backup is performed.
3) On all the other days, a backup of only the changed blocks since the last day's backup is performed.
Which backup strategy satisfies the requirements?

B. level 0 backup on Sunday, differential incrementalbackup on Wednesday and Friday, and cumulative incremental level 1 backup on all the other days
C. full database backup on Sunday, level 0 backup on Wednesday and Friday, and cumulative incremental level 1 backup on all the other days
D. full database backup on Sunday, level 0 backup on Wednesday and Friday, and differential incremental level 1 backup on all the other days

A. Each pluggable database (PDB) has its own initialization parameter file.
B. A PDB can have a private undo tablespace.
C. Log switches occur only at the container database level.
