Oracle Database 19c: Data Guard Administration Sample Questions (Q68-Q73):

NEW QUESTION # 68
On your logical standby database, you specified these rules:

After completion of the weekend batch cycle you attempt to delete the SQL Apply filters:

Which is TRUE regarding the execution of the UNSKIP procedure?

A. It deletes both the SQL Apply filters.
B. It succeeds only if all DML statements executed on the primary have been applied on the logical standby deleting the SQL Apply filter.
C. It returns an error because the syntax to delete a SQL Apply filter must specify the same object names as specified when the filter was added.
D. It succeeds but the SQL Apply filters are not deleted.
E. It succeeds only if SQL apply is stopped before deleting the SQL Apply filter.

Answer: A

Explanation:
The execution of the UNSKIP procedure is designed to remove SQL Apply filters that have been previously set up on a logical standby database. Based on the provided statements, the UNSKIP procedure is directed to delete any SQL Apply filters for DML statements associated with objects in the 'HR' schema that start with 'EMP'. Since both SKIP procedures had the same schema name ('HR') and statement type ('DML'), and the UNSKIP procedure uses a wildcard (%) for the object name, it will successfully remove both of the SQL Apply filters for 'EMP_NEW' and 'EMP_OLD', as both object names match the pattern provided in the UNSKIP procedure.
Reference:
Oracle's Data Guard documentation and SQL Language Reference provide insights into managing SQL Apply filters on a logical standby database using the DBMS_LOGSTDBY package. This includes adding and removing filters through SKIP and UNSKIP procedures.

NEW QUESTION # 69
Your Data Guard environment has one physical standby database using Real-Time Query. Two sequences have been created by these SQL statements:

Neither sequence has been used since being created.
Session 1 connects to the primary database instance and issues these two SQL statements:
SELECT a.nextval FROM DUAL; SELECT b.nextval FROM DUAL;
Then session 2 connects to the physical standby database instance and issues the same SQL statements. Which output will be seen for session 2?
Then session 2 connects to the physical standby database instance and issues the same SQL statements. Which output will be seen for session 2?

Answer: B

Explanation:
In Oracle, a sequence created with the GLOBAL keyword is available and can produce values across all sessions and instances. However, a sequence created with the SESSION keyword is only specific to the session it was created in. When the NEXTVAL is called for a sequence, it will increment according to the sequence's properties set during its creation.
Given the sequence creation statements and the actions performed:
* The a sequence is global, which means it is available across the entire database, including the standby database with Real-Time Query enabled. So, when session 2 calls a.nextval, it will get the next value in the sequence, which is 21 since session 1 already retrieved 1.
* The b sequence is session-specific, so when session 2 calls b.nextval, it will get the value 1 because for this new session on the standby, this is the first time the sequence is being accessed.
Therefore, the output for session 2 will be a output as 21 and b output as 1, which corresponds to Option C.
References: The behavior of global vs session-specific sequences is outlined in Oracle's SQL Language Reference under the CREATE SEQUENCE statement documentation.

NEW QUESTION # 70
Which two statements are true regarding Data Guard environments in an Oracle Muti-tenant architecture?

A. A Data Guard environment with a multi-tenant primary database can operate in any Protection mode.
B. Standby redo log files are required for each pluggable database that is protected with Data Guard.
C. The Data Guard broker may be used for multi-tenant databases.
D. Different redo transport methods can be configured for different pluggable databases within one Data Guard environment.
E. PDB_FILE_NAME CONVERT must be set to enable creation of standby databases if they are created on the same host as the primary.

Answer: A,C

Explanation:
Oracle Multi-tenant architecture and Data Guard have several interactions, but specific aspects hold true in such environments:
* The Data Guard broker may be used for multi-tenant databases (B): Data Guard Broker simplifies the management and monitoring of Data Guard configurations and is fully compatible with the Oracle Multi-tenant architecture, allowing for easy management of Data Guard configurations that include multi-tenant container databases (CDBs) and their pluggable databases (PDBs).
* A Data Guard environment with a multi-tenant primary database can operate in any Protection mode (E): Data Guard can be configured to operate in Maximum Performance, Maximum Availability, or Maximum Protection mode, regardless of whether the primary database is a multi-tenant database.
This flexibility ensures that Data Guard can meet various data protection and availability requirements in multi-tenant environments.References:
* Oracle Data Guard Broker documentation
* Oracle Multitenant Administrator's Guide

NEW QUESTION # 71
In Oracle Database 19c, you can set the value of database initialization parameters in a database using the EDIT DATABASE... SET PARAMETER Command:
DGMGRL> EDIT DATABASE 'boston' SET PARAMETER log_archive_trace - 1;
Which THREE statements are TRUE about the command?

A. The value set using this command is directly stored in the broker configuration file.
B. The EDIT DATABASE PARAMETER command can be used to set the value of a static parameter in a database.
C. The value set using this command is directly applied to the boston database.
D. The database must be available when the above command is run.
E. The edit database parameter command can only be used to modify the value of a dynamic parameter in a database.

Answer: C,D,E

Explanation:
The EDIT DATABASE...SET PARAMETER command in Data Guard Management (DGMGRL) is used to modify the value of initialization parameters for a database within a Data Guard configuration. This command can be used to modify both static and dynamic parameters, but if a static parameter is changed, the new value will take effect only after the database is restarted. The database must be up and running for the command to execute, and the values set using the command are directly applied to the specified database (in this case, 'boston') .

NEW QUESTION # 72
The Oracle database 19c Observer is currently running on host1 and you wish to have it running on host2.
Examine this list of possible steps:
1) Stop the observer on host1
2) Disable Fast-Start Failover
3) Update the broker configuration with the new observer hostname
4) Enable Fast-Start Failover
5) Start the Observer on host2
Which contains the minimum required steps to move the observer to host2?

A. Execute tasks 1 and 5
B. Execute tasks 1, 2, 3, 4, and 5
C. Execute tasks 1, 3, and 5
D. Execute only task 5

Answer: C

Explanation:
* Stop the Observer on host1 to ensure that there are no conflicts between the instances of the Observer running on different hosts.
* Update the Data Guard Broker configuration with the new hostname for the Observer. This step is crucial to redirect the Data Guard Broker to communicate with the Observer on the new host.
* Start the Observer on host2 to resume its operations in the new environment.
Disabling and re-enabling Fast-Start Failover (steps 2 and 4) are not strictly necessary for moving the Observer to a new host. These steps would be more relevant if changes to the configuration of Fast-Start Failover itself were required, which is not the case when simply relocating the Observer.
