Oracle Database 19c: Data Guard Administration Sample Questions (Q31-Q36):
NEW QUESTION # 31
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 creation requires that a LOG archive_dest_n parameter be defined in the standby that points back to the primary.
- C. Their usage will always have a performance impact on the primary database.
- D. Their usage may have a performance impact on the physical standby database if the CACHE size is too small.
- E. If the CACHE option is set then the size of the cache must be at least 100.
Answer: A,C,D
Explanation:
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.
NEW QUESTION # 32
Examine the Data Guard configuration:
DGMGRL> show configuration;
Configuration - Animals
Protection Mode: Max Availability
Databases:
dogs - Primary database sheep
- Physical standby database cats
- Physical standby database
Fast-Start Failover: DISABLED
Configuration Status: SUCCESS
An attempt to enable fast-start failover raises an error:
DGMGRL> enable fast_start failover;
Error: ORA-16693: requirements not met for enabling fast-start failover Failed.
Identify three possible reasons for this error.
- A. The LogxptModr property is set to async on Sheep while Sheep is the target standby database.
- B. The LogXptMode property is set to async on Dogs.
- C. The fastStartFailoverTarget property is not set on Dogs.
- D. The LogXptMode property is set to FASTSYNC on Cats while Sheep is the target standby database.
- E. The LogXptMode property is set to fastsync on Dogs.
Answer: A,B,C
Explanation:
When enabling fast-start failover, certain conditions must be met:
* The fastStartFailoverTarget property is not set on Dogs (A): The primary database (Dogs) needs to have a fast-start failover target configured for the operation to succeed.
* The LogXptMode property is set to ASYNC on Sheep while Sheep is the target standby database (B): Fast-start failover requires synchronous redo transport (SYNC or FASTSYNC) to ensure zero data loss, which is a prerequisite for enabling the feature.
* The LogXptMode property is set to ASYNC on Dogs (D): Similar to the previous point, the primary database must be configured to use synchronous redo transport for the fast-start failover to be possible.

NEW QUESTION # 33
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. ASYNC and Maximum Performance
- B. FASTSYNC and Maximum Availability
- C. FASTSYNC and Maximum Protection
- D. SYNC and Maximum Protection
Answer: B
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 # 34
A customer asks for your recommendation regarding this requirement:
1. We plan to have a Data Guard Configuration with one primary database and one physical standby database.
2. We want zero data loss in case of a disaster involving the loss of one component.
3. We want to do Real Application Testing occasionally on the Standby Database.
Which solution, if any, satisfies these requirements?
- A. These requirements cannot be met.
- B. A snapshot standby database with real time query that can be converted regularly into a physical standby database open read write, to do real application testing
- C. A far sync instance plus a snapshot standby database and real time apply that can be converted regularly into logical standby database to do real application testing
- D. A physical standby database with synchronous redo transport that can be converted regularly into a snapshot standby to do real application testing
Answer: D
Explanation:
* Synchronous redo transport for zero data loss (B): To guarantee zero data loss in the case of a disaster, synchronous redo transport must be configured between the primary and standby databases.
* Conversion to snapshot standby for testing (B): A physical standby database can be temporarily converted into a snapshot standby database to perform real application testing. After testing is completed, the snapshot standby can be converted back to a physical standby to resume its disaster recovery role.

NEW QUESTION # 35
Which THREE statements are TRUE about the supported workload in Active Data Guard standby databases?
- A. Read-mostly reporting applications that use global temporary tables for storing temporary data can be offloaded.
- B. PL/SQL blocks that you run on Active Data Guard standby databases can be always redirected to and run on the primary database.
- C. The DML operations on a standby can be transparently redirected to and run on the primary database
- D. The DDL operations on private temporary tables are transparently redirected to the primary database.
- E. You might have to use sequences with global temporary tables to support read-mostly applications by using Active Data Guard.
Answer: A,C,E
Explanation:
In an Oracle Active Data Guard environment:
* B: Read-mostly reporting applications that utilize global temporary tables to store session-specific data can be effectively offloaded to an Active Data Guard standby database, reducing the load on the primary database.
* C: Sequences can be used with global temporary tables on an Active Data Guard standby database to support certain types of read-mostly applications, though some restrictions on sequence use may apply.
* E: In Oracle Database 19c and later, DML redirection allows DML operations performed on an Active Data Guard standby database to be transparently redirected to the primary database. This is part of the DML Redirection feature.
Option A is incorrect because not all PL/SQL blocks run on an Active Data Guard standby database can be redirected to the primary database. Some PL/SQL executions, specifically those that would attempt to make changes to the database, are not supported on the standby.
Option D is incorrect because DDL operations on private temporary tables are not redirected; instead, private temporary tables are session-specific and are not persisted on disk, so they do not generate redo and are not applicable to an Active Data Guard standby.
References: The behavior and capabilities of Active Data Guard standby databases are documented in the Oracle Data Guard Concepts and Administration guide and the Active Data Guard documentation.
