Q2. You are administering a database stored in Automatic Storage Management (ASM). You use RMAN to back up the database and the MD_BACKUP command to back up the ASM metadata regularly. You lost an ASM disk group DG1 due to hardware failure.

In which three ways can you re-create the lost disk group and restore the data?

A. Use the MD_RESTORE command to restore metadata for an existing disk group by passing the existing disk group name as an input parameter and use RMAN to restore the data. 

B. Use the MKDG command to restore the disk group with the same configuration as the backed-up disk group and data on the disk group.

C. Use the MD_RESTORE command to restore the disk group with the changed disk group specification, failure group specification, name, and other attributes and use RMAN to restore the data. 

D. Use the MKDG command to restore the disk group with the same configuration as the backed-up disk group name and same set of disks and failure group configuration, and use RMAN to restore the data. 

E. Use the MD_RESTORE command to restore both the metadata and data for the failed disk group.

F. Use the MKDG command to add a new disk group DG1 with the same or different specifications for failure group and other attributes and use RMAN to restore the data.

Q5. A database is stored in an Automatic Storage Management (ASM) disk group, disk group, DGROUP1 with SQL:

There is enough free space in the disk group for mirroring to be done.

What happens if the CONTROLLER1 failure group becomes unavailable due to error of for maintenance?

A. Transactions and queries accessing database objects contained in any tablespace stored in DGROUP1 will fall.

B. Mirroring of allocation units will be done to ASM disks in the CONTROLLER2 failure group until the CONTROLLER1 for failure group is brought back online.

C. The data in the CONTROLLER1 failure group is copied to the controller2 failure group and rebalancing is initiated. 

D. ASM does not mirror any data until the controller failure group is brought back online, and newly allocated primary allocation units (AU) are stored in the controller2 failure group, without mirroring.

E. Transactions accessing database objects contained in any tablespace stored in DGROUP1 will fail but queries will succeed. 

Answer: B

Q6. On your Oracle Database, you issue the following commands to create indexes:

SQL > CREATE INDEX oe.ord_customer_ix1 ON oe.orders (customer_id, sales_rep_id) INVISIBLE;

Which two statements are true?

A. Only the ORD_CUSTOMER_IX1 index created. 

B. Both the indexes are updated when a row is inserted, updated, or deleted in the ORDERS table.

C. Both the indexes are created: however, only ORD_CUSTOMERS_IX1 is used by the optimizer for queries on the ORDERS table.

D. The ORD_CUSTOMER_IX1 index is not used by the optimizer even when the OPTIMIZER_USE_INVISIBLE_INDEXES parameters is set to true.

E. Both the indexes are created and used by the optimizer for queries on the ORDERS table.

F. Both the indexes are created: however, only ORD_CUSTOMERS_IX2 is used by the optimizer for queries on the ORDERS table.

Answer: BF

Q7. You notice that the elapsed time for an important database scheduler Job is unacceptably long.

The job belongs to a scheduler job class and window. Which two actions would reduce the job's elapsed time?

A. Increasing the priority of the job class to which the job belongs

B. Increasing the job's relative priority within the Job class to which it belongs

C. Increasing the resource allocation for the consumer group mapped to the scheduler job's job class within the plan mapped to the scheduler window

D. Moving the job to an existing higher priority scheduler window with the same schedule and duration

E. Increasing the value of the JOB_QUEUE_PROCESSES parameter

F. Increasing the priority of the scheduler window to which the job belongs

Answer: CF

Q8. You execute the following PL/SQL:

B. FGA is enabled for the PRODUCTS.PRICE column and an audit record is written whenever a row with PRICE > 10000 is accessed. 

C. FGA is enabled for all DML operations by JIM on the PRODUCTS.PRICE column.

D. FGA is enabled for the PRICE column of the PRODUCTS table and the SQL statements is captured in the FGA audit trial.

Answer: AD

Q9. In your multitenant container database (CDB) containing pluggable database (PDBs), the HR user executes the following commands to create and grant privileges on a procedure:
