Oracle Database 19c: Data Guard Administration 1z0-076 Prüfungsfragen mit Lösungen (Q69-Q74):

69. Frage
Which two statements are true regarding Data Guard environments in an Oracle Muti-tenant architecture?

A. Different redo transport methods can be configured for different pluggable databases within one Data Guard environment.
B. A Data Guard environment with a multi-tenant primary database can operate in any Protection mode.
C. The Data Guard broker may be used for multi-tenant databases.
D. Standby redo log files are required for each pluggable database that is protected with Data Guard.
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.

Antwort: B,C

Begründung:
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.

70. Frage
Which THREE statements are TRUE about Global Sequences when connected to a physical standby database with Real-Time Query enabled?

A. They must have the NOORDEK and CACHE options set.
B. Their usage may have a performance impact on the physical standby database if the CACHE size is too small.
C. Their creation requires that a LOG archive_dest_n parameter be defined in the standby that points back to the primary.
D. Their usage will always have a performance impact on the primary database.
E. If the CACHE option is set then the size of the cache must be at least 100.

Antwort: A,B,D

Begründung:
Global Sequences are Oracle sequences that generate unique values across multiple instances in an Oracle RAC or a Data Guard configuration. Regarding their behavior and performance when connected to a physical standby database with Real-Time Query enabled:
* A: The usage of Global Sequences can indeed have a performance impact on the primary database due to the need to generate unique values that are consistent across both primary and standby databases.
* D: The performance impact on the physical standby database may occur if the CACHE size is too small. This is because the standby database will frequently have to access the primary database to replenish the cache, which can increase the load and potentially lead to performance degradation.
* E: Global Sequences should have the NOORDER and CACHE options set. The NOORDER option ensures that sequence numbers are provided without guaranteeing sequence order, thus improving scalability and performance. The CACHE option is used to specify how many sequence values will be held in memory for faster access.
Option B is incorrect as the LOG_ARCHIVE_DEST_n parameter's definition for standbys pointing back to the primary does not directly pertain to the creation of sequences.
Option C is incorrect because there is no requirement that the size of the cache for a sequence must be at least
100. The CACHE size can be set to a different number based on specific use cases or performance considerations.
References: Oracle's documentation on sequences and their behavior in a Data Guard environment provides insights into the performance considerations and best practices for using sequences, particularly in a Real-Time Query context.

71. Frage
Which three are prerequisites for using Data Guard Broker?

A. If any database in the configuration is a RAC database, then the broker configuration files must reside in shared storage accessible by all database instances for all databases in the broker configuration.
B. Network connectivity to the primary database instance must be defined on the servers hosting the standby database instances.
C. A statically defined listener end-point must be registered with the local listener on the servers hosting the standby database instances.
D. The primary and standby databases must run the same version of the Oracle Database server.
E. The broker configuration files for a RAC database must reside in shared storage accessible by all the RAC database instances.
F. DG_BROKEB_START must be set to TRUE for a database instance before adding the database to the broker configuration.

Antwort: A,B,D

Begründung:
Data Guard Broker is a management tool that simplifies the configuration, management, and monitoring of Data Guard environments. The prerequisites for using Data Guard Broker include:
The primary and standby databases must run the same version of the Oracle Database server (A): This ensures compatibility between the primary and standby databases and enables seamless role transitions and data synchronization.
Network connectivity to the primary database instance must be defined on the servers hosting the standby database instances (B): Proper network connectivity is essential for communication between the primary and standby databases, allowing for the replication of data and the synchronization of changes.
If any database in the configuration is a RAC database, then the broker configuration files must reside in shared storage accessible by all database instances for all databases in the broker configuration (D): In Real Application Clusters (RAC) environments, shared storage ensures that all instances of the RAC database can access the broker configuration files, facilitating the management of the Data Guard environment across all instances.

72. Frage
You have a Data Guard Broker configuration called 'Somewhere' as shown:
DGMGRL> SHOW CONFIGURATION;
Configuration - Somewhere
Protection Mode: MaxPerformance
Databases:
Nearby - Primary database
FS - Far Sync
Farout - Physical standby database
Fast-Start Failover: DISABLED
Configuration Status:
SUCCESS
You then run this command:
DGMGRL> SHOW DATABASE 'Nearby' 'InconsistentProperties';
Which two are true about the output of this DGMGRL command?

A. A far sync instance cannot have inconsistent properties because it has no database.
B. Any inconsistency reported is on an instance-specific basis.
C. It shows all properties whose broker configuration values for database Nearby are inconsistent with the values in the corresponding server parameter file or the runtime values for database instance Nearby.
D. It shows all properties whose broker configuration values for database Nearby are inconsistent with the broker configuration values for database Farout.

Antwort: A,C

73. Frage
Your Data Guard configuration consists of these components and settings:
1. A primary database
2. A remote physical standby database
3. Real-time query is enabled
4. Redo transport mode is synchronous
5. Protection mode is maximum availability
6. The Data Guard broker is used
You notice that the standby destination fails to acknowledge reception of redo within net_timeout period of time.
Which is true in this scenario?

A. Real-time query will be disabled on the physical standby.
B. The protection mode will automatically change to Maximum Performance.
C. Synchronous redo transport mode connections to the standby database are terminated.
D. The physical standby database instance is shut down by the Data Guard broker.

Antwort: C

Begründung:
In a Data Guard configuration where the protection mode is set to Maximum Availability and synchronous redo transport is enabled, if the standby destination fails to acknowledge the reception of redo within the net_timeout period, the primary database will terminate the synchronous redo transport mode connections to the standby database to protect the primary database from hanging (C). The primary database then operates in a Maximum Performance mode until the issue is resolved. This behavior ensures that the primary database can continue to process transactions even when the standby database is temporarily unavailable.
Reference:
The Oracle Data Guard Broker documentation and Oracle Data Guard Concepts and Administration guide detail the behavior of different protection modes and the response to network timeouts, including the fallback to asynchronous redo transport to maintain primary database availability.
