NEW QUESTION 45
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.

 
 
 
 
 
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 46
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.

 
 
 
 
 
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.

NEW QUESTION 47
The Oracle database 19c Observer is currently running on host1 and you wish to have it running on host2.
Examine this list of possible steps:
1) Stop the observer on host1
2) Disable Fast-Start Failover
3) Update the broker configuration with the new observer hostname
4) Enable Fast-Start Failover
5) Start the Observer on host2
Which contains the minimum required steps to move the observer to host2?

 
 
 
 
* Stop the Observer on host1 to ensure that there are no conflicts between the instances of the Observer running on different hosts.
* Update the Data Guard Broker configuration with the new hostname for the Observer. This step is crucial to redirect the Data Guard Broker to communicate with the Observer on the new host.
* Start the Observer on host2 to resume its operations in the new environment.
Disabling and re-enabling Fast-Start Failover (steps 2 and 4) are not strictly necessary for moving the Observer to a new host. These steps would be more relevant if changes to the configuration of Fast-Start Failover itself were required, which is not the case when simply relocating the Observer.

NEW QUESTION 48
Which THREE are true about using flashback database in a Data Guard environment?

 
 
 
 
 
 
Flashback Database is a feature that allows reverting a database to a previous point in time, which is extremely useful in various Data Guard configurations:
* It may be used to flash back a physical standby that receives redo from a far sync instance (C):
Flashback Database can be used on a physical standby database to revert it to a past point in time, even when it is receiving redo data from a far sync instance. This can be particularly useful to recover from logical corruptions or unwanted changes.
* You can use it when real-time apply is enabled in case the physical standby suffers from logical corruption (D): Even when real-time apply is enabled, which allows redo data to be applied to the standby database as soon as it is received, Flashback Database can be used to revert the physical standby database to a point in time before the logical corruption occurred.
* It may not be used to flash back a primary database after a failover to a physical standby (E):
After a failover has occurred from a primary to a physical standby database, making the standby the new primary, Flashback Database cannot be used to revert the old primary database to a state before the failover because the failover operation makes irreversible changes to the database role and configuration.References:
* Oracle Database Backup and Recovery User’s Guide
* Oracle Data Guard Concepts and Administration

NEW QUESTION 49
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?

 
 
 
 
 

NEW QUESTION 50
Which two statements are true regarding asynchronous redo transport in a Data Guard

 
 
 
 
 
Asynchronous redo transport is a method where the primary database does not wait for an acknowledgment from the standby database before committing transactions, which helps in minimizing the impact on the primary database’s performance (B). This transport mode is associated with the Maximum Performance data protection mode, which prioritizes performance over synchronicity of data between the primary and standby databases (C). While it provides a level of data protection, there could be some data loss in the event of a primary database failure because redo data may not have been transmitted to the standby database at the time of the failure.
References:Oracle Data Guard Concepts and Administration documentation provides detailed explanations of different redo transport modes and their implications on data protection and performance. Asynchronous transport mode’s behavior and association with Maximum Performance mode are outlined explicitly.

NEW QUESTION 51
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?

 
 
 
 

NEW QUESTION 52
Which TWO statements are true about configuring Oracle Net Service in a Data Guard environment?

 
 
 
 
 
A static service must be registered with the local listener to enable DGMGRL to restart instances during the course of broker operations (A): For DGMGRL (Data Guard Manager Command-Line Interface) to perform instance management operations, such as restarting instances, a static service registration in the listener is required. This allows the broker to connect to the database instance even when the instance is not fully up and the dynamic service registration is not available.
Installing the oracle-database-preinstall-19c package is NOT sufficient to set up operating system kernel parameters for Oracle Net (C): While the oracle-database-preinstall-19c package automates the setting of several kernel parameters to meet the preinstallation requirements for Oracle Database, it does not specifically tailor all settings for Oracle Net in a Data Guard configuration. Additional manual configuration may be required to optimize Oracle Net services for Data Guard operations.
Reference:
Oracle Data Guard Broker documentation
Oracle Net Services Administrator’s Guide

NEW QUESTION 53
Which THREE statements are true about Far Sync instances?

 
 
 
 
 
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.References:
* Oracle Data Guard Concepts and Administration Guide
* Oracle Database High Availability Overview

NEW QUESTION 54
Which three can be done using Data Guard Broker?

 
 
 
 
 
 

NEW QUESTION 55
Examine the Data Guard configuration: DGMGRL> show configuration;
Configuration – Animals
Protection Mode: MaxPerformance
Databases:
dogs- Primary database
sheep – Physical standby database
cats- Snapshot standby database
Fast-Start Failover: DISABLED
Configuration Status: SUCCESS
You receive an error while attempting to raise the protection mode to Maximum Protection:
DGMGRL> edit configuration set protection mode as maxprotection;
Error: ORA-16627: operation disallowed since no standby databases would remain to support protection mode Failed.
What can you conclude based on this error?

 
 
 
 
Comprehensive Detailed Explanation:
In an Oracle Data Guard environment, the Maximum Protection mode requires that all redo data be transmitted synchronously to at least one standby database, ensuring no data loss even in the event of a primary database failure. However, a snapshot standby database, by its nature, allows read-write access and is temporarily disconnected from the redo stream, which makes it unable to participate in the synchronous redo transport required by Maximum Protection mode. The presence of a snapshot standby database in the Data Guard configuration thus prevents the activation of Maximum Protection mode, as it cannot guarantee zero data loss without a standby database capable of receiving redo data synchronously.
Reference:
Oracle Data Guard documentation clearly outlines the requirements and restrictions of different protection modes, including the necessity for standby databases to participate in synchronous redo transport to enable Maximum Protection mode. The inability of snapshot standby databases to fulfill this requirement is a key consideration when planning Data Guard configurations and protection levels.
Explanation:
The error indicates that switching the protection mode to Maximum Protection is not possible due to the presence of a snapshot standby database in the Data Guard configuration, which cannot participate in synchronous redo transport required by the Maximum Protection mode. Therefore, the correct answer is:

NEW QUESTION 56
There are currently 6 applief. and 6 pfepafef processes running and no idle applier processes on y logical standby database.
The max_SERVERS SQL apply parameter and number of archiver processes are both set to 12.
Identify two changes, each of which would allow you to increase the number of applier processes.

 
 
 
 
 
To increase the number of applier processes on a logical standby database, the following changes can be made:
* C: Increasing the value for the MAX_SERVERS SQL apply parameter would allow for more applier processes to be initiated, assuming that system resources permit.
* D: Increasing the PARALLEL_MAX_SERVERS initialization parameter would allow for more parallel execution processes, which can be used by SQL apply to increase the number of applier processes.
Option A is incorrect as decreasing the number of archiver processes will not necessarily increase the number of applier processes; these are unrelated components.
Option B is incorrect because the ‘FREPARER’ processes do not exist, it seems to be a typographical error, and the ‘REPARER’ is not a valid Oracle process or parameter.
Option E is incorrect because the RECOVERY_PARALLELISM parameter controls the number of processes used for instance recovery and media recovery, not for SQL apply.
References: Oracle Data Guard Concepts and Administration guide details the configuration and tuning of SQL apply-related parameters in logical standby databases.

NEW QUESTION 57
You are planning to perform block comparison using the dbms comp package:

Which TWO statements are true?

 
 
 
 
 
The DBMS_COMPARISON package, used for comparing and converging data objects within a single database or between databases, requires that the databases involved in the block comparison be at least mounted (A). This allows the procedure to access the data blocks for comparison. Additionally, the progress of long-running operations such as block comparison can be monitored using the dynamic performance view V$SESSION_LONGOPS (D), which provides information on the operation’s progress and estimated completion time.
References:Oracle Database PL/SQL Packages and Types Reference provides comprehensive details on the DBMS_COMPARISON package, including its procedures and how to monitor their progress. Additionally, Oracle Database Reference explains the V$SESSION_LONGOPS view, which is commonly used for monitoring long operations in the database.

NEW QUESTION 58
Which four requirements can be met by deploying a logical standby database?

 
 
 
 
 
 
 
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.
