QUESTION 70
You want to reduce fragmentation and reclaim unused space for the sales table but not its dependent objects. During this operation, you want to ensure the following:
i. Long-running queries are not affected.
ii. No extra space is used.
iii. Data manipulation language (DML) operations on the table succeed at all times throughout the process.
iv. Unused space is reclaimed both above and below the high water mark.
Which alter TABLE option would you recommend?

A.    DEALLOCATE UNUSED
B.    SHRINK SPACE CASCADE
C.    SHRINK SPACE COMPACT
D.    ROW STORE COMPRESSBASIC

Answer: C
Explanation:
https://docs.oracle.com/cd/B28359_01/server.111/b28310/schema003.htm
The COMPACT clause lets you divide the shrink segment operation into two phases. When you specify COMPACT, Oracle Database defragments the segment space and compacts the table rows but postpones the resetting of the high water mark and the deallocation of the space until a future time. This option is useful if you have long-running queries that might span the operation and attempt to read from blocks that have been reclaimed. The defragmentation and compaction results are saved to disk, so the data movement does not have to be redone during the second phase. You can reissue the SHRINK SPACE clause without the COMPACT clause during off-peak hours to complete the second phase.

QUESTION 71
You have a production Oracle 12c database running on a host. You want to install and create databases across multiple new machines that do not have any Oracle database software installed. You also want the new databases to have the same directory structure and components as your existing 12c database. The steps in random order:
1. Create directory structures similar to the production database on all new machines.
2. Create a response file for Oracle Universal Installer (OUI) with the same configurations as the production database.
3. Create a database clone template for the database.
4. Run the Database Configuration Assistant (DBCA) to create the database.
5. Run OUI in graphical mode on each machine.
6. Run OUI in silent mode using the OUI response file.
Identify the required steps in the correct sequence to achieve the requirement with minimal human intervention.

A.    2, 1, 6, and 4
B.    2, 3, and 6
C.    3, 1, 5, and 6
D.    2, 3, 1, and 6

B.    specifying the maximum number of concurrent sessions allowed for a user
C.    specifying the amount of private space a session can allocate in the shared pool of the SGA
D.    limiting the degree of parallelism of operations performed by a user or group of users
E.    specifying an idle time limit that applies to sessions that are idle and blocking other sessions

Answer: DE
Explanation:
Limit the degree of parallelism of any operation performed by members of a group of users. Limit the amount of time that a session can be idle. This can be further defined to mean only sessions that are blocking other sessions.

QUESTION 73
Your multitenant container database (CDB) contains multiple pluggable databases (PDBs). You execute the command to create a common user:
SQL> CREATE USER c##a_admin
IDENTIFIED BY password
DEFAULT TABLESPACE users
QUOTA I00M ON users
TEMPORARY TABLESPACE temp;
Which statement is true about the execution of the command?

A.    The common user is created in the CDB and all the PDBs, and uses the users and temp tablespaces of the CDB to store schema objects.
B.    The command succeeds only if all the PDBs have the users and temp tablespaces.
C.    The command gives an error because the container=all clause is missing.
D.    The command succeeds and sets the default permanent tablespace of a PDB as the default tablespace for the c##a_admin user if the users tabiespace does not exist in that PDB.

Answer: B
Explanation:
When creating a common user, any tablespace, tablespace group or profile specified in the CREATE command must exist in every PDB. If none of these are specified, the default TABLESPACE, TEMPORARY TABLESPACE, and PROFILE for the PDB will be used.

QUESTION 74
Which two statements are true about the Automatic Diagnostic Repository (ADR)?

A.    The ADR base is shared across multiple instances.
B.    The ADR base keeps all diagnostic information in binary format.
C.    The ADR can be used to store statspack snapshots to diagnose database performance issues.
D.    The ADR can be used for problem diagnosis even when the database instance is down.
E.    The ADR is used to store Automatic Workload Repository (AWR) snapshots.

Answer: AD

QUESTION 75
user_data is a nonencryptedtablespace containing tables with data. You must encrypt ail data in this tablespace. Which three methods can do this?

A.    Use Data Pump
B.    Use ALTERTABLE … MOVE
C.    Use CREATE TABLE AS SELECT
D.    Use alter tablespace to encrypt the tablespace after enabling row movement on all its
E.    Use altertablespace to encrypt the tablespace

Answer: ABC
Explanation:
http://www.oracle.com/technetwork/testcontent/o19tte-086996.html
Finally, note that you can only create encrypted tablespaces; you cannot modify existing tablespaces to encrypt them. So, when you need existing data in encrypted tablespaces, the best solution is to first create encrypted tablespaces and then move the objects from the unencrypted tablespaces to them.
