• Question 84:

  Identify two situations in which the alert log file is updated.

  A. Running a query on a table returns ORA-600: Internal Error.

  B. Inserting a value into a table returns ORA-01722: invalid number.

  C. Creating a table returns ORA-00955: name us already in used by an existing objects.

  D. Inserting a value into a table returns ORA-00001: unique constraint (SYS.OK_TECHP) violated.

  E. Rebuilding an index using ALTER INDEX ... REBUILD fails with an ORA-01578: ORACLE data block corrupted (file # 14, block # 50) error.

  Correct Answer: AE

  The alert log is a chronological log of messages and errors, and includes the following items: All internal errors (ORA-600), block corruption errors (ORA-1578), and deadlock errors (ORA-60) that occur Administrative operations, such as CREATE, ALTER, and DROP statements and STARTUP, SHUTDOWN, and ARCHIVELOG statements Messages and errors relating to the functions of shared server and dispatcher processes Errors occurring during the automatic refresh of a materialized view The values of all initialization parameters that had nondefault values at the time the database and instance start

  Note:

  * The alert log file (also referred to as the ALERT.LOG) is a chronological log of messages and errors written out by an Oracle Database. Typical messages found in this file is: database startup, shutdown, log switches, space errors, etc. This file should constantly be monitored to detect unexpected messages and corruptions.

• Question 85:

  Which three statements are true about Oracle Data Pump export and import operations?

  A. You can detach from a data pump export job and reattach later.

  B. Data pump uses parallel execution server processes to implement parallel import.

  C. Data pump import requires the import file to be in a directory owned by the oracle owner.

  D. The master table is the last object to be exported by the data pump.

  E. You can detach from a data pump import job and reattach later.

• Question 86:

  Examine the query and its output executed In an RDBMS Instance:

  

  Which three statements are true about the users (other than sys) in the output?

  A. The C # # B_ADMIN user can perform all backup and recovery operations using RMAN only.

  B. The C # # C_ADMIN user can perform the data guard operation with Data Guard Broker.

  C. The C # # A_ADMIN user can perform wallet operations.

  D. The C # # D_ADMIN user can perform backup and recovery operations for Automatic Storage Management (ASM).

  E. The C # # B_ADMIN user can perform all backup and recovery operations using RMAN or SQL* Plus.

  Correct Answer: BDE

  B: SYSDG administrative privilege has ability to perform Data Guard operations (including startup and shutdown) using Data Guard Broker or dgmgrl.

  D: SYSASM The new (introduced in 11g) SYSASM role to manage the ASM instance, variable extent sizes to reduce shared pool usage, and the ability of an instance to read from a specific disk of a diskgroup

  E (Not A): SYSDBA is like a role in the sense that it is granted, but SYSDBA is a special built-in privilege to allow the DBA full control over the database

  Incorrect Answers:

  C: SYSKM. SYSKM administrative privilege has ability to perform transparent data encryption wallet operations.

  Note:

  Use the V$PWFILE_USERS view to see the users who have been granted administrative privileges.

• Question 87:

  In your Database, the TBS PERCENT USED parameter is set to 60 and the TBS PERCENT FREE parameter is set to 20.

  Which two storage-tiering actions might be automated when using information Lifecycle Management (ILM) to automate data movement?

  A. The movement of all segments to a target tablespace with a higher degree of compression, on a different storage tier, when the source tablespace exceeds TBS PERCENT USED

  B. Setting the target tablespace to read-only

  C. The movement of some segments to a target tablespace with a higher degree of compression, on a different storage tier, when the source tablespace exceeds TBS PERCENT USED

  D. Setting the target tablespace offline

  E. The movement of some blocks to a target tablespace with a lower degree of compression, on a different storage tier, when the source tablespace exceeds TBS PERCENT USED

  Correct Answer: BC

  The value for TBS_PERCENT_USED specifies the percentage of the tablespace quota when a tablespace is considered full. The value for TBS_PERCENT_FREE specifies the targeted free percentage for the tablespace. When the percentage of the tablespace quota reaches the value of TBS_PERCENT_USED, ADO begins to move data so that percent free of the tablespace quota approaches the value of TBS_PERCENT_FREE. This action by ADO is a best effort and not a guarantee.

• Question 88:

  Which three statements are true about Flashback Database? (Choose three.)

  A. Flashback logs are written sequentially, and are archived.

  B. Flashback Database uses a restored control file to recover a database.

  C. The Oracle database automatically creates, deletes, and resizes flashback logs in the Fast Recovery Area.

  D. Flashback Database can recover a database to the state that it was in before a RESETLOGS operation.

  E. Flashback Database can recover a data file that was dropped during the span of time of the flashback.

  F. Flashback logs are used to restore to the before images of blocks, so that redo data may be used to roll forward to the desired flashback time.

  Correct Answer: CDF

• Question 89:

  In your multitenant container database (CDB) containing same pluggable databases (PDBs), you execute the following commands in the root container:

  

  Which two statements are true?

  A. The C # # ROLE1 role is created in the root database and all the PDBs.

  B. The C # # ROLE1 role is created only in the root database because the container clause is not used.

  C. Privileges are granted to the C##A_ADMIN user only in the root database.

  D. Privileges are granted to the C##A_ADMIN user in the root database and all PDBs.

  E. The statement for granting a role to a user fails because the CONTAINER clause is not used.

  Correct Answer: AC

  * You can include the CONTAINER clause in several SQL statements, such as the CREATE USER,

  ALTER USER, CREATE ROLE, GRANT, REVOKE, and ALTER SYSTEM statements.

  * * CREATE ROLE with CONTAINER (optional) clause

  / CONTAINER = ALL

  Creates a common role.

  / CONTAINER = CURRENT

  Creates a local role in the current PDB.
