However, to pass the Oracle 1z0-076 Exam you have to prepare well. For the quick Oracle 1z0-076 exam preparation the 1z0-076 Questions is the right choice.

Oracle Database 19c: Data Guard Administration Sample Questions (Q57-Q62):

NEW QUESTION # 57
You must design an Oracle Data Guard configuration for a DSS database that meets these permanent requirements:
1. Creating and maintaining bitmap indexes should not impact the performance of the primary database.
2. Creating and maintaining materialized views should not impact the performance of the primary database.
Additionally, there are these requirements, only one of which is ever done at any one time:
1. It should be possible to apply designated patches with a minimum amount of downtime.
2. Upgrading to a new database release should be performed with the least possible amount of downtime.
3. New application software releases should be tested against an exact and up-to-date replica of the primary database.
Which configuration meets these requirements with the fewest of databases?

A. a primary database with one logical standby database
B. a primary database with two physical standby databases
C. a primary database with one physical standby database
D. A primary database with one logical and one physical standby database
E. a primary database with two logical standby databases

Answer: A

Explanation:
* Logical standby databases allow the execution of DDL and DML operations, which makes them suitable for maintaining bitmap indexes and materialized views without affecting the performance of the primary database .
* Logical standby databases can be used for performing rolling upgrades and patching with minimum downtime, meeting another requirement .
* They also enable the testing of new application software releases against an up-to-date replica of the primary database, fulfilling the last requirement.
Other configurations involving physical standby databases or combinations of logical and physical standby databases might not meet all the specified requirements as efficiently or with the same level of performance isolation for the primary database.

NEW QUESTION # 58
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 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.
B. It succeeds only if SQL apply is stopped before deleting the SQL Apply filter.
C. It deletes both the SQL Apply filters.
D. It succeeds only if all DML statements executed on the primary have been applied on the logical standby deleting the SQL Apply filter.
E. It succeeds but the SQL Apply filters are not deleted.

Answer: C

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 # 59
You must configure flashback database for your Oracle 19c databases that will be part of a Data Guard Broker configuration.
The databases are all in ARCHIVELOG mode.
You will execute the SQL statement:
ALTER DATABASE FLASHBACK ON;
Which three are true concerning this command?

A. It will execute successfully while an Oracle 19c primary database is mounted.
B. If executed successfully on an Oracle 19c primary database, flashback will also be enabled on all physical standby databases that are part of the configuration.
C. It will execute successfully on an Oracle 19c physical standby database while Real Time Query is active.
D. If executed successfully on an Oracle 19c primary database, flashback will also be enabled on all logical standby databases that are part of the configuration.
E. It will execute successfully on an Oracle 19c logical standby database while SQL apply is active.
F. It will execute successfully while an Oracle 19c primary database is open.

Answer: A,E,F

Explanation:
The command ALTER DATABASE FLASHBACK ON; enables the Flashback Database feature, which provides a way to quickly revert an entire Oracle database back to a previous point in time. This command can be executed while an Oracle 19c primary database is either open (option A) or mounted (option B). It is also applicable to an Oracle 19c logical standby database while SQL Apply is active (option E). However, it's important to note that enabling Flashback Database on the primary does not automatically enable it on all associated standby databases, whether they are physical or logical. Each database in a Data Guard configuration must have Flashback Database explicitly enabled if desired. Real Time Query being active on a physical standby does not directly relate to the ability to execute this command on the standby. Reference: The explanation is based on Oracle's concepts for Flashback Technology and Data Guard configurations as detailed in the Oracle Database Backup and Recovery User's Guide and the Oracle Data Guard Concepts and Administration guide.

NEW QUESTION # 60
You created a physical standby database prodsbyi from the primary database prod using SQL and RMAN. Which THREE are prerequisites for creating a Data Guard Broker configuration to manage these databases?

A. The DG_BROKER_START parameter must be set to TRUE for both database instances.
B. A local net service name to enable connectivity to the PRODSBYI database instance must be defined on the primary database host.
C. The standby database must have supplemental logging enabled.
D. The primary database must have FORCE LOGGING enabled.
E. The LOG_ARCHIVE_DEST_n parameters with the service attribute set must be cleared.
F. The primary database must have supplemental logging enabled.

Answer: A,B,F

Explanation:
When setting up a Data Guard Broker configuration for a primary database and its physical standby, the following prerequisites must be met:
A: Oracle Net connectivity must be defined on both the primary and standby hosts to enable the respective database instances to communicate with each other.
B: Supplemental logging is required on the primary database because it provides additional logging necessary for the standby database to be able to apply changes from the primary database accurately.
F: The DG_BROKER_START parameter must be set to TRUE for both the primary and standby database instances. This parameter is used to start the Data Guard Broker process which manages the configuration.
Options C and D are not prerequisites for creating a Data Guard Broker configuration. Additionally, while FORCE LOGGING mode (option E) is recommended as a best practice to prevent possible data inconsistencies during media recovery, it is not a strict prerequisite for creating a Data Guard Broker configuration.

NEW QUESTION # 61
Which four statements are true regarding SQL Apply filters for a logical standby database?

A. They can be used to skip ALTER TABLE commands on specific tables.
B. They can be used to skip ALTE1 STEM and ALTER DATABASE commands.
C. They can be used to skip CREATE TABLE commands.
D. They can be used to stop SQL apply if it encounters an error.
E. They can be used to skip execution of DML triggers on a table while allowing the DML to execute.
F. They can be used to skip all SQL statements executed on a specific pluggable database (PDB) within a standby multitenant container database (CDB).
G. They can only be used to skip DML statements on a table.

Answer: A,B,C,E

Explanation:
Based on the Oracle Database 19c documentation, the correct answers about SQL Apply filters for a logical standby database are:A. They can be used to skip execution of DML triggers on a table while allowing the DML to execute.B. They can be used to skip CREATE TABLE commands.C. They can be used to skip ALTER SYSTEM and ALTER DATABASE commands.G. They can be used to skip ALTER TABLE commands on specific tables.
Comprehensive Detailed Explanation:SQL Apply filters in a logical standby database can be set to control which SQL operations are applied to the standby. These filters allow for certain commands to be skipped, ensuring that they do not impact the standby database. For example, filters can be used to skip the execution of DML triggers to prevent them from firing during SQL Apply, while still allowing the underlying DML to be executed on the logical standby database. This is particularly useful when certain triggers are not desired to run in a standby environment. CREATE TABLE, ALTER SYSTEM, ALTER DATABASE, and specific ALTER TABLE commands can also be skipped using SQL Apply filters to prevent unwanted structural changes or administrative operations from affecting the logical standby database. These capabilities provide a level of control to ensure that the logical standby database reflects only the desired state of the primary database.
References:Oracle Database SQL Language Reference and Oracle Data Guard Concepts and Administration guide offer comprehensive details on the use of SQL Apply filters, including the range of SQL statements that can be influenced by these filters in a logical standby database environment.
