Oracle Database 19c: Data Guard Administration Sample Questions (Q51-Q56):

NEW QUESTION # 51
You must configure an Oracle Data..........
1. A primary database
2. A physical standby database
Examine these requirements: 1. Data loss is not permitted.
1. Data loss is not permitted.
2. It should be possible to convert the physical standby database to a snapshot standby database.
3. Under normal operations, transactions should commit when redo is written to disk on the primary database and as soon as it has been received by the standby database instance.
4. The availability of the primary database should not be compromised by the availability of the standby database.
5. It should be possible to convert the physical standby database to a logical standby database
6. It should be possible to deploy Real Application Clusters on the primary database.
7. It should be possible to deploy Real Application Clusters on the physical standby database.
You configure SYNC redo transport mode in combination with Maximum Protection mode.

A. 1, 2, 6, and 7
B. 1, 2, and 5
C. 1, 2, 3, 4, 5, 6, and 7
D. 1, 2, 3, 6, and 7
E. 1, 6, and 7

Answer: C

Explanation:
When SYNC redo transport mode is combined with Maximum Protection mode, it ensures that no data loss will occur (requirement 1). The physical standby can be converted to a snapshot standby (requirement 2) and later to a logical standby database (requirement 5), satisfying both transformation requirements. Transactions commit as soon as redo data is received by the standby database (requirement 3). The availability of the primary is not dependent on the standby database in Maximum Protection mode, as the primary database will halt if the standby cannot acknowledge the redo (requirement 4), thus indirectly ensuring its availability. It is also possible to deploy Real Application Clusters on both the primary (requirement 6) and the physical standby database (requirement 7), providing high availability and scalability.
Reference
Oracle Data Guard documentation detailing the requirements for different database roles, protection modes, and redo transport modes, as well as the capabilities and limitations of each configuration.

NEW QUESTION # 52
Which four requirements can be met by deploying a logical standby database?

A. It can be used to create additional schemas.
B. Support for workloads requiring additional indexes.
C. It can be used to create additional tables.
D. Support for workloads requiring additional materialized views.
E. It can be used for Real Application Testing without affecting the disaster recovery capabilities.
F. It must provide a disaster-recovery solution that protects all data with capability of performing switchovers and failovers.
G. It must have the same physical structure as the primary database.

Answer: B,C,D,E

Explanation:
A logical standby database is part of Oracle Data Guard and allows the standby database to be open for read-write operations, providing additional flexibility. The requirements met by a logical standby database include:
Support for workloads requiring additional materialized views (A): Logical standby databases can support materialized views, allowing for complex data summarization and reporting workloads.
It can be used to create additional tables (C): Unlike physical standby databases, logical standby databases allow for the creation of additional tables that do not exist in the primary database, enabling custom workloads and reporting.
It can be used for Real Application Testing without affecting the disaster recovery capabilities (E): Logical standby databases can be used to test application changes, patches, and upgrades while still maintaining their role as part of the disaster recovery strategy.
Support for workloads requiring additional indexes (F): Logical standby databases allow for the creation of additional indexes to optimize query performance for reporting and analytical workloads.

NEW QUESTION # 53
Which two are prerequisites for configuring flashback database for Oracle 19c databases, in a Data Guard environment?

A. The Data Guard real-time apply feature must be enabled.
B. The data guard broker must be used.
C. A far sync instance must be configured to flash back a standby when the primary has been flashed back.
D. The database must be in ARCHTVELOG mode.
E. A fast recovery area must be configured.

Answer: D,E

Explanation:
A fast recovery area must be configured (B): Flashback Database requires a fast recovery area to be set up because flashback logs are stored there. The fast recovery area is a unified storage location for all recovery-related files and activities.
The database must be in ARCHIVELOG mode (C): Flashback Database operation relies on the ability to archive redo logs. Therefore, the database must be running in ARCHIVELOG mode for Flashback Database to be enabled.

NEW QUESTION # 54
You are monitoring your Data Guard broker configuration and issue this set of DGMGRL commands:
DGMGRL> SHOW CONFIGURATION;
Configuration - DRSolution
Protection Mode: MaxPerformance
Databases:
Close_by - Primary database
FS_inst - Far Sync
Far_away - Physical standby database
Fast-Start Failover: DISABLED
Configuration Status:
SUCCESS
What is true concerning this configuration?

A. The FS_inst Far Sync instance forwards redo to the Far_away physical standby only if the Close_by primary database is not able to do so.
B. The Far Sync instance will not forward redo to the Far_away physical standby because the Protection mode is not MaxProtection.
C. The Far Sync instance will not forward redo to the Far_away physical standby because Fast-Start Failover is disabled.
D. The Close_by primary database instance forwards redo to the FS_inst Far Sync instance, which forwards the redo in turn to the Far_away physical standby database instance.
E. The Close_by primary database forwards redo to the Far_away physical standby directly and also sends redo to the FS_inst Far Sync instance.

Answer: D

NEW QUESTION # 55
Which three Data Guard monitoring activities may be performed using Enterprise Manager Cloud Control?

A. You can monitor the redo apply rate on a logical standby database.
B. You can monitor the redo apply rate on a snapshot standby database.
C. You can check if redo apply needs to be tuned.
D. You can check the potential data loss in the event of a disaster.
E. You can set a warning threshold on the redo generation rate metric for a physical standby database.
F. You can set a critical threshold on the redo generation rate metric for a primary database.

Answer: A,D,F
