NEW QUESTION 1
Examine the list of possible steps to transport a tablespace across platforms that have the same compatibility level, character sets, and endian format:
1. Make the tablespace read-only at the source database.
2. Export metadata from the source database.
3. Import metadata into the target database.
4. Transfer the dump file and data files to the target machine.
5. Convert data files by using Recovery Manager (RMAN).
6. Make the tablespace read-write at the target database.
Identify the required steps in the correct order. (Choose the best answer.)

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

D. 1, 5, 2, 4, 3, and 6

Answer: A

NEW QUESTION 2
You are administering a multitenant container database (CDB) that contains multiple pluggable databases (PDBs). You are connected to cdb$root as the sys user. You execute the commands: SQL> CREATE USER C##ADMIN IDENTIFIED BY orcll23;
SQL> CREATE ROLE C##CONNECT;
SQL> GRANT CREATE SESSION, CREATE TABLE, SELECT ANY TABLE TO C##CONNECT; SQL> GRANT C##CONNECT to C##ADMIN CONTAINER=ALL;
Which statement is true about the c##connect role?

A. It is created only in cdb$root and cannot be granted to the c##admin user with the container=all clause.
B. It is granted to the c##admin user only in the CDB.
C. It is granted to the c##admin user in all PDBs and can be granted only to a local user in a PDB.
D. It is granted to the c##admin user in all PDBs and can be granted object and system privileges for a PDB.

Answer: D

Explanation: https://docs.oracle.com/database/121/SQLRF/statements_6014.htm#SQLRF01311
“CONTAINER Clause The CONTAINER clause applies when you are connected to a CDB. However, it is not necessary to specify the CONTAINER clause because its default values are the only allowed
values. To create a common role, you must be connected to the root. You can optionally specify CONTAINER = ALL, which is the default when you are connected to the root. To create a local role, you must be connected to a PDB. You can optionally specify CONTAINER = CURRENT, which is the default when you are connected to a PDB.”

NEW QUESTION 3
Which three statements are true about Oracle Secure Backup (OSB)?

A. It can encrypt client data written to tape.
B. It can be used to take image copy backups to tape.
C. It can be used to manage tape backup and restore operations for multiple databases.
D. It can be used along with an RMAN recovery catalog for maintaining records of backups in a tape library.
E. It can be used to perform file system backups at the file, directory, file system, or raw partition level.

Answer: ACE

Explanation: File system backups may be performed at the file, directory, file system or raw partition level with full, incremental and offsite backup scheduling. As backup needs grow requiring more tape drives and centralized backup management of multiple servers, Oracle Secure Backup XE can be easily upgraded to the Oracle Secure Backup edition. http://www.oracle.com/technetwork/products/secure-backup/learnmore/osb-xe-10-130649.pdf

NEW QUESTION 4
Your database supports an OLTP workload. Examine the output of the query:
SQL> SELECT target_mttr, estimated_mttr FROM v$instance_recovery
Target_mttr estimated_mttr
---------------------- --------------------------- 0 76
To ensure faster instance recovery, you set the fast_start_mttr_target initialization parameter to 30. What is the effect of this setting on the database?

A. Automatic checkpoint tuning is disabled.
B. The frequency of log switches is increased.
C. The overhead on database performance is increased because of frequent writes to disk.
D. The MTTR advisor is disable

Answer: C

Explanation: Reference: http://docs.oracle.com/cd/A97630_01/server.920/a96533/instreco.htm

NEW QUESTION 5
Examine the command to duplicate a database: RMAN> DUPLICATE TARGET DATABASE TO cdb PLUGGABLE DATABASE pdb1, pdb5;
Which two statements are true about the DUPLICATE command?

A. The SPFILE is copied along with the data files of the pluggable databases (PDBs).
B. The root and the seed database in the container database (CDB) are also duplicated.
C. A backup of pdb1 and pd5 must exist before executing the command.
D. The duplicate command first creates a backup, and then duplicates the PDBs by using the backup.
E. An auxiliary instance must be started with the initialization parameter ENABLE_PLUGGABLE_DATABASE set to TRUE.

Answer: BE

Explanation: Do backups of the source database exist? The principal advantage of active database duplication is that it does not require source database backups. Active duplication copies mounted or online database files over a network to the auxiliary instance. One disadvantage of this technique is the negative performance effect on the network. Another disadvantage is that the source database is running processes required to transfer the files to the auxiliary host, thereby affecting the source database and production workload. If the source database backups exist, and if the effect on the network is unacceptable, then backup-based duplication may be a better option. You can copy backups to temporary storage and transfer them manually to the destination host. If duplication is made with a connection to the target or the recovery catalog, then the backup files on the destination host must have the same file specification as they had on the source host. Otherwise, this is not a requirement.

NEW QUESTION 6
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 after the segments are moved
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. Taking the target tablespace offline after the segments are moved
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

The threshold for activating tiering policies is based on two parameters: TBS PERCENT USED
TBS PERCENT FREE
Both values can be controlled by the DBMS_ILM_ADMIN package.
TBS PERCENT USED and TBS PERCENT FREE default to 85 and 25, respectively. Hence, whenever the source tablespace’s usage percentage goes beyond 85 percent, any tiering policy specified on its
objects will be executed and objects will be moved to the target tablespace until the source tablespace becomes at least 25 percent free. Note that it is possible to add a custom condition to tiering policies to enable movement of data based on conditions other than how full the tablespace is.
In addition, the READ ONLY option must be explicitly specified for the target tablespace. 2021-04-01T21:59:00.56
