Oracle Database 19c: Data Guard Administration Sample Questions (Q72-Q77):

NEW QUESTION # 72
Which three are true about using RMAN in a Data Guard environment?

A. A recovery catalog is required when RMAN is used to take backups from a logical standby database in a Data Guard configuration if you plan to recover the primary using those backups.
B. Backups of control files taken on a physical standby are not interchangeable with a primary.
C. A recovery catalog is required when RMAN is used to take backups from a physical standby database if you plan to recover the primary using those backups.
D. Backups of data files taken on a physical standby are interchangeable with a primary.
E. Backups of archived redo logs taken on a physical standby are interchangeable with a primary.

Answer: B,D,E

NEW QUESTION # 73
Which TWO statements are true about Real-Time Query?

A. Setting standby_max_data_delay=0 requires synchronous redo transport.
B. A standby database enabled for Real-Time Query cannot be the Fast-Start Failover target of the Data Guard configuration.
C. Real-Time Query has no limitations regarding the protection level of the Data Guard environment.
D. Disabling Real-Time Query prevents the automatic start of redo apply when a physical standby databases opened read only.
E. Real-Time Query sessions can be connected to a Far Sync instance.

Answer: A,D

Explanation:
Real-Time Query is a feature that allows queries to be run on a physical standby database while it is applying redo data. The relevant truths about it are:
* Setting standby_max_data_delay=0 requires synchronous redo transport (A): For the real-time apply feature to function with no data delay (zero delay), synchronous redo transport must be used. This setting ensures that the data on the standby database is as current as possible before queries are executed against it.
* Disabling Real-Time Query prevents the automatic start of redo apply when a physical standby database is opened read-only (C): If Real-Time Query is disabled, opening the standby database in read-only mode will not start the redo apply process automatically. Redo apply needs to be manually started to synchronize the standby database with the primary.References:

NEW QUESTION # 74
You must configure on Oracle Data .......
1. A primary database
2. Three Physical Standby Databases
Examine these requirements:
A designated physical standby database should become the primary database automatically whenever the primary database fails.
2. The chosen protection mode should provide the highest level of protection possible without violating the other requirement.
Which redo transport mode and protection mode would you configure to meet these requirements?

A. SYNC and Maximum Protection
B. ASYNC and Maximum Performance
C. FASTSYNC and Maximum Protection
D. FASTSYNC and Maximum Availability

Answer: D

Explanation:
To meet the requirements of automatic failover and the highest level of protection without data loss, the combination of FASTSYNC redo transport mode and Maximum Availability protection mode is appropriate.
FASTSYNC ensures that the performance impact on the primary database is minimized while still providing synchronous transport. Maximum Availability protection mode offers the highest level of data protection without compromising the availability of the primary database. In case of a network failure or a standby failure, the primary will not halt, avoiding disruption to the primary database operations.
ReferencesOracle Data Guard Concepts and Administration guide, which details the different protection modes and their respective levels of data protection and impact on database operations.

NEW QUESTION # 75
Which TWO statements are true regarding Data Guard Broker?

A. It automatically starts the DMON process for the database instances that are part of a Data Guard configuration.
B. It can be used to create and manage standby databases.
C. It can be used to monitor redo transport and log apply services.
D. It automatically adds the primary database to an existing broker configuration when Enterprise Manager Cloud Control is used to create a standby.
E. It can be used to perform failovers and switchovers.

Answer: B,E

NEW QUESTION # 76
Which THREE statements are true about Far Sync instances?

A. The Data Guard Broker must be used to deploy and manage Far Sync instances.
B. They work with any protection level.
C. They use an spfMe, a standby controlfile, and standby redo logs.
D. They enable standby databases to be configured at remote distances from the primary without impacting performance on the primary.
E. A primary database can ship redo directly to multiple Far Sync instances.

Answer: A,D,E

Explanation:
Far Sync instances are a feature of Oracle Data Guard designed to support zero data loss protection over long distances:
The Data Guard Broker must be used to deploy and manage Far Sync instances (A): Data Guard Broker simplifies the deployment and management of Far Sync instances, which are an integral part of zero data loss protection configurations.
They enable standby databases to be configured at remote distances from the primary without impacting performance on the primary (C): Far Sync instances are designed to receive redo from the primary database and then forward it to a remote standby database, thereby avoiding any performance impact on the primary database itself.
A primary database can ship redo directly to multiple Far Sync instances (E): A primary database can be configured to send redo logs to more than one Far Sync instance, which can then forward the redo to their respective remote standby databases.
