Oracle Database 19c: Data Guard Administration Sample Questions (Q64-Q69):NEW QUESTION # 64
You have a Data Guard broker configuration consisting of:
A primary database
One local physical standby database
One far sync instance
A remote physical standby database
The broker configuration was created with the DGMGRL utility after creating all the databases and the far sync instance with command-line tools.
What is the correct way to add this configuration to Enterprise Manager Cloud Control assuming all the nodes have been discovered already as Enterprise Manager targets?
Answer: A

NEW QUESTION # 65
Which TWO are benefits of using Transaction Guard in a Data Guard environment?
Answer: A,E
Explanation:
Transaction Guard provides benefits in terms of transaction consistency and recovery in a Data Guard environment:
* It provides application continuity by rolling back uncommitted transactions interrupted by a failover or switchover (B): Transaction Guard ensures that any uncommitted transactions at the time of an outage are rolled back consistently, thus preserving the integrity of the application's data and state.
* It protects against recoverable errors during a planned or an unplanned outage of a primary database (D): Transaction Guard offers protection against errors that can occur during outages, allowing applications to resume operations more quickly and reliably after recovery.References:

NEW QUESTION # 66
Which four statements are true regarding SQL Apply filters for a logical standby database?
Answer: A,C,E,F
Explanation:
Based on the Oracle Database 19c documentation, the correct answers about SQL Apply filters for a logical standby database are:A. They can be used to skip execution of DML triggers on a table while allowing the DML to execute.B. They can be used to skip CREATE TABLE commands.C. They can be used to skip ALTER SYSTEM and ALTER DATABASE commands.G. They can be used to skip ALTER TABLE commands on specific tables.
Comprehensive Detailed Explanation:SQL Apply filters in a logical standby database can be set to control which SQL operations are applied to the standby. These filters allow for certain commands to be skipped, ensuring that they do not impact the standby database. For example, filters can be used to skip the execution of DML triggers to prevent them from firing during SQL Apply, while still allowing the underlying DML to be executed on the logical standby database. This is particularly useful when certain triggers are not desired to run in a standby environment. CREATE TABLE, ALTER SYSTEM, ALTER DATABASE, and specific ALTER TABLE commands can also be skipped using SQL Apply filters to prevent unwanted structural changes or administrative operations from affecting the logical standby database. These capabilities provide a level of control to ensure that the logical standby database reflects only the desired state of the primary database.
References:Oracle Database SQL Language Reference and Oracle Data Guard Concepts and Administration guide offer comprehensive details on the use of SQL Apply filters, including the range of SQL statements that can be influenced by these filters in a logical standby database environment.

NEW QUESTION # 67
Which feature is available when monitoring a Data Guard configuration using Enterprise Manager Cloud Control, but is not available using DGMGRL or by using SQL?
Answer: A

NEW QUESTION # 68
Which THREE statements are TRUE about Global Sequences when connected to a physical standby database with Real-Time Query enabled?
Answer: B,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.
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.
