In CDB$ROOT of your multitenant container database (CDB), you create a common user, C##A_ADMIN, and then execute the command:
Which statement is true?
A. The command executes successfully, enabling the C##A_ADMIN user to create a tablespace only in the root database.
B. The command executes successfully, enabling the C##A_ADMIN user to create tablespaces in the root database, as well as in the pluggable databases (PDBs).
C. The command fails because the CONTAINER clause is not used.
D. The command fails because system privileges cannot be granted to a common user.
Identify three benefits of unified auditing. (Choose three.)
A. It helps to reduce disk space used to store an audit trail in a database.
B. It guarantees zero-loss auditing.
C. It reduces overhead on a database caused by auditing, by having a single audit trail.
D. An audit trail cannot be modified because it is read-only.
E. It automatically audits Recovery Manager (RMAN) events.
You are administering a multitenant container database (COB) that contains two pluggable databases (PDBs), pdb1 and pdb2. You are connected to pdb2 as a common user with DBA privileges.
The statistics_level parameter is PDB modifiable.
As the user sys, execute the following command on pdb2:
SQL> ALTER SYSTEM SET STATISTICS_LEVEL=ALL SID='*' SCOPE=SPFILE;
Which statement is true about the result of this command?
A. The statistics_level parameter is set to all when any of the PDBs is reopened.
B. The statistics_level parameter is set to all only for PDB2 when it is reopened.
C. The statistics_level parameter is set to all when the root database is restarted.
D. The statement is ignored because there is no SPFILE for a PDB.
Which two statements are true about service creation for pluggable databases (PDBs)? (Choose two.)
A. When a PDB is created, a service is automatically started in the instance with the same name as the PDB.
B. The default service 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 using the 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.
Which three statements are true about persistent lightweight jobs? (Choose three.)
A. A user cannot set privileges on them.
B. They generate large amounts of metadata.
C. They may be created as fully self-contained jobs.
D. They must reference an existing Scheduler Program.
E. They are useful when users need to create a large number of jobs quickly.
Examine the RMAN command:
RMAN> BACKUP VALIDATE DATABASE; Which statement is true about the execution of the command?
A. Block change tracking must be enabled before executing this command.
B. The database must be running in archivelog mode for the successful execution of this command.
C. A complete database backup must exist before executing this command.
D. The command checks for blocks containing all zeros, an invalid checksum, or a corrupt block header.
E. The command checks for blocks that contain a valid checksum and matching headers and footers, but that has logically inconsistent contents.
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.
As part of a manual upgrade process, after installing the software for Oracle Database 12c and preparing the new Oracle home, you shut down the existing single-instance database.
Which step should you perform next to start the upgrade of the database?
A. Start up the database instance by using the new location of the server parameter file and run the catuppst.sqi script to generate informational messages and log files during the upgrade.
B. Start up the database instance by using the new location of the server parameter file and run the cact1.pl script from the new Oracle home to use parallel upgrade options that reduce down time.
C. Start up the database instance by using the STARTUP UPGRADE command and gather fixed object statistics to minimize the time needed for recompilation.
D. Start up the database instance by using the STARTUP UPGRADE command, which opens the existing database, and then performs additional upgrade operations.
Examine the RMAN command:
RMAN> SET ENCRYPTION IDENTIFIED BY
Which type of encryption is used for the backup performed by using this command?
A. password-mode encryption
B. dual-mode encryption
C. transparent encryption
D. default encryption
A telecom company wishes to generate monthly bills to include details of customer calls, listed in order of time of call.
Which table organization allows for generating the bills with minimum degree of row sorting?
A. a hash cluster
B. an index cluster
C. a partitioned table
D. a sorted hash cluster
E. a heap table with a rowid column
