Oracle Database 19c: Data Guard Administration Sample Questions (Q95-Q100):

NEW QUESTION # 95
A Data Guard environment has this configuration and these attributes:
A primary database
A physical standby database named sbdb
The configuration is in maximum availability protection mode.
Then sbdb is converted to a snapshot standby database.
Which two statements are true?

A. sbdb can still receive redo.
B. sbdb can still apply redo.
C. The recovery point objective increases.
D. The protection mode is lowered to maximum performance.
E. The recovery time objective increases.

Answer: A,C

NEW QUESTION # 96
You are licensed to use Oracle Active Data Guard.
Which TWO statements are true after enabling block change tracking on a physical standby database?

A. It starts the CTWR process on the physical standby database instance.
B. It allows fast incremental backups to be taken on the primary database.
C. It starts the RVWR process on the physical standby database instance.
D. It starts the CTWR process on the primary database instance.
E. It allows fast incremental backups to be offloaded to the physical standby database.
F. It allows fast incremental backups to be offloaded to a snapshot standby database, when the physical standby database is converted.

Answer: C,E

Explanation:
Block change tracking is a feature that enhances the efficiency of incremental backups by recording changed blocks in a tracking file. When used with Oracle Active Data Guard:
* It starts the RVWR process on the physical standby database instance (A): When block change tracking is enabled on a physical standby database, the Recovery Writer (RVWR) process is initiated.
This process is responsible for recording the changes to blocks in the block change tracking file, which is then used to optimize incremental backups.
* It allows fast incremental backups to be offloaded to the physical standby database (E): With block change tracking enabled on the physical standby database, fast incremental backups can be offloaded from the primary database. This reduces the workload on the primary database and utilizes the standby database for backup operations, improving overall system performance and efficiency.References:

* Oracle Active Data Guard documentation

NEW QUESTION # 97
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. 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.
B. It shows all properties whose broker configuration values for database Nearby are inconsistent with the broker configuration values for database Farout.
C. Any inconsistency reported is on an instance-specific basis.
D. A far sync instance cannot have inconsistent properties because it has no database.

Answer: A,D

NEW QUESTION # 98
Which FOUR database parameters might be affected by or influence the creation of standby databases?

A. DB_NAME
B. STANDBY_ARCHIVE_DEST
C. db_file_name_convert
D. COMPATIBLE
E. ARCHIVE_LAG_TARGET
F. FALSERVER

Answer: A,B,C,D

Explanation:
* DB_NAME (A): The name of the database, which should remain consistent across the primary and standby databases.
* db_file_name_convert (C): This parameter helps define the mapping of data file names from the primary to the standby database, which is crucial during the creation and operation of a standby database.
* COMPATIBLE (D): The compatibility level can influence the features that can be used on the standby database and must be consistent with or higher than that of the primary database, especially after upgrades.
* STANDBY_ARCHIVE_DEST (F): This parameter specifies the destination of archived redo log files on the standby database, which is important for log transport and apply services.

NEW QUESTION # 99
Which THREE statements are true about snapshot standby databases?

A. FLASHBACK DATABASE is enabled automatically on a snapshot standby database after converting it from a physical standby database if not already enabled.
B. A snapshot standby database may be opened read-only.
C. FLASHBACK DATABASE must be manually enabled on a physical standby database before converting it into a snapshot standby database.
D. A snapshot standby database may be opened read-write.
E. A snapshot standby database can have Real-Time apply enabled.
F. FLASHBACK DATABASE is enabled automatically on a physical standby database as part of the conversion into a snapshot standby database, if not already enabled.

Answer: A,D,F

Explanation:
Snapshot standby databases are a feature of Oracle Data Guard that allows a physical standby database to be temporarily converted into a read-write database for testing or other purposes. The true statements about snapshot standby databases are:
* FLASHBACK DATABASE is enabled automatically on a snapshot standby database after converting it from a physical standby database if not already enabled (B): When a physical standby is converted to a snapshot standby, FLASHBACK DATABASE is automatically enabled to allow the database to be easily reverted back to its original state.
* FLASHBACK DATABASE is enabled automatically on a physical standby database as part of the conversion into a snapshot standby database, if not already enabled (C): As part of the conversion process, FLASHBACK DATABASE is turned on to ensure that changes made while the database is in snapshot standby mode can be undone.
* A snapshot standby database may be opened read-write (E): Once a physical standby is converted to a snapshot standby, it can be opened for read-write operations, allowing for testing and other tasks that require a writable database.
