NEW QUESTION # 47
Which three are prerequisites for enabling Fast-Start Failover?
- A. Flashback Database must be enabled on the Fast-Start Failover target standby database.
- B. The Fast-Start Failover target standby database may receive REDO either synchronously or asynchronously when the configuration operates in Maximum Performance mode.
- C. The Fast-Start Failover target standby database must receive REDO synchronously when the configuration operates in Maximum Availability mode.
- D. Flashback Database must be enabled on the primary database.
- E. A static service name must be configured only for the Fast-Start Failover target standby database.
Answer: A,C,D
NEW QUESTION # 48
Which TWO statements are true about Real-Time Query?
- A. A standby database enabled for Real-Time Query cannot be the Fast-Start Failover target of the Data Guard configuration.
- B. Real-Time Query has no limitations regarding the protection level of the Data Guard environment.
- C. Setting standby_max_data_delay=0 requires synchronous redo transport.
- D. Real-Time Query sessions can be connected to a Far Sync instance.
- E. Disabling Real-Time Query prevents the automatic start of redo apply when a physical standby databases opened read only.
Answer: C,E
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 # 49
Which three are true concerning database states after a successful switchover?
- A. The former primary database will always be open.
- B. If the former primary database became a logical standby database it will be open read-write.
- C. If the former primary database became a physical standby database it will always be open readonly.
- D. The new primary database will be open read-write.
- E. If the former primary database became a logical standby database it will be in mount state.
- F. If the former primary database became a physical standby database it will be in the same state as the former physical standby database.
Answer: B,D,F
Explanation:
After a successful switchover operation in a Data Guard environment, the new primary database (the former standby) will be open read-write (option A). If the former primary database transitions to a logical standby database, it will also be open read-write (option C), allowing it to apply redo data while servicing read-only queries. The former primary, if converted to a physical standby, will adopt the state that the former physical standby database was in prior to the switchover, which can vary based on the configuration prior to the switchover (option D). The state of a physical standby database can range from mounted to open read-only, depending on whether Real-Time Query was enabled. Thus, the exact state will depend on the pre-switchover setup. It's also essential to highlight that options B and E suggest specific states for a former primary turned logical standby, and a former primary turned physical standby, respectively, but these states are not fixed and depend on the configurations set up by the database administrators. References: The answers are corroborated by Oracle's documentation on Data Guard switchovers, specifically in the Oracle Data Guard Concepts and Administration guide, which explains the roles and states of databases in a Data Guard configuration before and after switchovers.
NEW QUESTION # 50
Which TWO statements are true about Far Sync instances?
- A. They work in Maximum Performance mode.
- B. They do not work with Logical Standby databases.
- C. They work in Maximum Protection mode.
- D. They work in Maximum Availability mode.
- E. They do not work with Snapshot Standby databases.
Answer: A,B
NEW QUESTION # 51
Which TWO statements are true about configuring Oracle Net Service in a Data Guard environment?
- A. Installing the oracle-database-preinstall-19c package is NOT sufficient to set up operating system kernel parameters for Oracle Net.
- B. Enterprise Manager does not require static service registration to restart instances during the course of broker operations.
- C. A static service must be registered with the local listener to enable DGMGRL to restart instances during the course of broker operations.
- D. Install the oracle-database-preinstall-19c package to set the kernel parameters for Oracle Net based on the Data Guard best practice guidelines.
- E. It is necessary to use the failover clause for an address_list with multiple address lists in the tnsnames.ora file.
Answer: A,C
Explanation:
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.

NEW QUESTION # 52
A customer asks you to propose the most appropriate solution for this set of requirements:
We need a disaster recovery solution that enables us to fail over from our production database with zero data loss.
We want to generate reports from the proposed standby database at the same time that it is used for data protection.
Developers may need to test occasionally on a copy of the live database Which TWO solutions would you recommend?
- A. A snapshot standby database with synchronous redo transport
- B. A logical standby database with real-time apply enabled
- C. A logical standby database with real-time query enabled
- D. A physical standby database with real-time apply enabled
- E. A physical standby database with real-time query enabled
Answer: C,E
NEW QUESTION # 53
Your Data Guard environment has a remote physical standby database with real-time query enabled, which is used for reporting, and a logical standby database used for DSS reporting.
Switchovers or failovers are possible due to testing or in case of a disaster.
Clients use local TNSNAMES.ORA files to define connection strings to the database instances.
Which three will prevent clients from connecting to the wrong database instances?
- A. The DB_NAME and DB_UNIQUE_NAME parameters must be set to the same value for all the databases in the Data Guard environment.
- B. The LOCAL_LISTENER parameter on the primary database instance must always be set.
- C. The client applications must use the correct TNS entries when requesting connections to the database instances.
- D. Client TNS entries for the databases use the correct service names for the intended service.
- E. The standby database services must be defined statically with the Listeners running on the standby database hosts.
- F. Oracle Net connectivity to the primary database instance must be established on all the standby database instances.
- G. A service name is registered with the local listener of each database instance.
Answer: C,D,E
Explanation:
Based on Oracle Database 19c: Data Guard Administration documents, the three measures that can prevent clients from connecting to the wrong database instances during switchovers, failovers, or regular operations in a Data Guard environment are:
* B. The standby database services must be defined statically with the Listeners running on the standby database hosts.
* D. The client applications must use the correct TNS entries when requesting connections to the database instances.
* E. Client TNS entries for the databases use the correct service names for the intended service.
* In an Oracle Data Guard configuration, correctly configuring Oracle Net Services (including TNS entries and listeners) is crucial for ensuring that clients connect to the appropriate database instance, whether it's the primary or standby. Defining services on the standby database and associating them with listeners ensures that client applications can connect to the standby when needed, especially useful in a role transition or when the standby is open for read-only access or real-time query. It's essential that TNS entries used by client applications specify the correct service names that correspond to the intended
* database roles, such as primary or standby. This setup facilitates seamless connectivity to the appropriate instance based on the role, especially critical during switchovers and failovers when the roles of the databases change.
* References:Oracle's Data Guard concepts and administration guide provides extensive information on configuring network services for Data Guard environments, ensuring that applications connect to the correct database instance based on the current role of the databases in the Data Guard configuration.
NEW QUESTION # 54
Which two are true about database roles in an Oracle Data Guard configuration?
- A. A configuration consisting only of a primary and one or more physical standby databases can support a rolling release upgrade.
- B. A Logical Standby Database can cascade redo to a terminal destination.
- C. A Logical Standby Database can be converted to a Snapshot Standby Database.
- D. A Snapshot Standby Database can be a fast-start failover target.
- E. A Physical Standby Database can be converted into a Logical Standby Database.
Answer: A,E
Explanation:
A Physical Standby Database can indeed be converted into a Logical Standby Database, providing flexibility in a Data Guard configuration. This allows for the database to switch roles and supports SQL apply operations, enabling more granular control over the data and transactions being replicated and applied. Additionally, having a configuration with a primary database and one or more physical standby databases allows for rolling upgrades to be performed. This means that each database in the Data Guard configuration can be upgraded in a phased manner, minimizing downtime and ensuring high availability during the upgrade process.
NEW QUESTION # 55
A customer has these requirements for their proposed Data Guard implementation:
1. Zero data loss must still be guaranteed through the loss of any one configuration component.
2. The primary database must be protected against a regional disaster.
3. Performance overheads on the primary should be minimized as much as possible given these requirements.
4. Downtime on the primary database for any reason must be kept to a minimum.
Components referred to in the broker commands are:
- A.
- B.
- C.
- D.
Answer: A
Explanation:
According to the requirements stated:
* Zero data loss must be guaranteed despite the loss of any one component: This necessitates synchronous redo transport to at least one standby database (for no data loss).
* The primary database must be protected against a regional disaster: This implies that there must be a standby database in a different region.
* Performance overhead on the primary should be minimized: This suggests that asynchronous transport should be used where possible to reduce the performance impact on the primary.
* Downtime on the primary for any reason must be kept to a minimum: This is indicative of a requirement for a fast failover mechanism, possibly with a fast-start failover (FSFO) and high availability.
Given these requirements, the appropriate option that fulfills all these is:
* Option C, where 'prima' is the primary database, 'fs1' is the Far Sync instance in the primary region, and
'physt' and 'physt2' are physical standby databases in the primary and remote regions, respectively. In this configuration:
* 'prima' is set to send redo to 'fs1' using SYNC to guarantee zero data loss.
* 'fs1' is set to send redo to 'physt' (local standby) using FASTSYNC, which is a low-latency synchronous transport that is optimized for performance.
* The Data Guard configuration's protection mode is set to MAXAVAILABILITY to provide the highest level of data protection that is possible without compromising the availability of the primary database.
This configuration ensures that there is zero data loss even if the primary region is completely lost, maintains performance by limiting the synchronous transport to the local region with a Far Sync instance, and has a remote standby database in a separate region for disaster recovery purposes.

NEW QUESTION # 56
Which three Data Guard monitoring activities may be performed using Enterprise Manager Cloud Control?
- A. You can check the potential data loss in the event of a disaster.
- B. You can monitor the redo apply rate on a snapshot standby database.
- C. You can set a critical threshold on the redo generation rate metric for a primary database.
- D. You can monitor the redo apply rate on a logical standby database.
- E. You can check if redo apply needs to be tuned.
- F. You can set a warning threshold on the redo generation rate metric for a physical standby database.
Answer: A,C,D
NEW QUESTION # 57
Which TWO observations are true about the Far Sync instance?
- A. Can be created using the RMAN DUPLICATE command
- B. Receives redo synchronously from the primary database
- C. Includes a standby control file, password file, data files, standby redo logs, and archive logs
- D. Applies redo received
- E. Can only be created using a series of SQL commands
Answer: B,D
Explanation:
A Far Sync instance is a special kind of Oracle Data Guard configuration that allows synchronous redo transport from a primary database to a remote standby database with minimum impact on the primary database's performance. The Far Sync instance receives redo data synchronously from the primary database (A), then ships it asynchronously to the remote standby database, thus extending zero data loss protection over longer distances and higher network latency environments than would be practical with a synchronous standby alone. The Far Sync instance does not apply the redo data; it just receives and ships it (E). A Far Sync instance does not have data files, and it cannot apply redo to stay synchronized with the primary database.
Reference:
Oracle Database High Availability Overview and Oracle Data Guard Concepts and Administration documentation detail the role and configuration of Far Sync instances, including how they contribute to achieving zero data loss disaster recovery over long distances.
NEW QUESTION # 58
Which TWO statements correctly describe the behavior of Automatic Block Media Recovery in a Data Guard environment, for a corrupt block in the example tablespace encountered by a session logged in as the SH user?
- A. A corrupt block on the primary database can be automatically recovered, using a block from a standby database with Real-Time Query enabled.
- B. A corrupt block on the primary database is automatically recovered, using a block from a flashback log from the primary database.
- C. A corrupt block on a standby database with Real-Time Query enabled, is automatically recovered, using flashback logs from the standby database.
- D. A corrupt block on a standby database with Real-Time Query enabled, can be automatically recovered, using a block from the primary database.
- E. A corrupt block on the primary database is automatically recovered, using a block from a flashback log from a standby database with Real-Time Query enabled.
Answer: A,B
Explanation:
Automatic Block Media Recovery can be a significant feature for maintaining data integrity within a Data Guard configuration.
* A corrupt block on the primary database can be automatically recovered, using a block from a standby database with Real-Time Query enabled (A): When a corrupted block is encountered on the primary database, Oracle can automatically replace it with a good block from the standby database where Real-Time Query is enabled, leveraging the standby as a source of good data.
* A corrupt block on the primary database is automatically recovered, using a block from a flashback log from the primary database (E): If a good block version is available in the flashback logs of the primary database, Automatic Block Media Recovery can use it to recover the corrupted block on the primary.References:

NEW QUESTION # 59
Which THREE statements are TRUE about the supported workload in Active Data Guard standby databases?
- A. PL/SQL blocks that you run on Active Data Guard standby databases can be always redirected to and run on the primary database.
- B. You might have to use sequences with global temporary tables to support read-mostly applications by using Active Data Guard.
- 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. Read-mostly reporting applications that use global temporary tables for storing temporary data can be offloaded.
Answer: B,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.
NEW QUESTION # 60
Which three are prerequisites for using Data Guard Broker?
- A. DG_BROKEB_START must be set to TRUE for a database instance before adding the database to the broker configuration.
- B. Network connectivity to the primary database instance must be defined on the servers hosting the standby database instances.
- C. The broker configuration files for a RAC database must reside in shared storage accessible by all the RAC database instances.
- D. If any database in the configuration is a RAC database, then the broker configuration files must reside in shared storage accessible by all database instances for all databases in the broker configuration.
- E. The primary and standby databases must run the same version of the Oracle Database server.
- F. A statically defined listener end-point must be registered with the local listener on the servers hosting the standby database instances.
Answer: B,D,E
Explanation:
Data Guard Broker is a management tool that simplifies the configuration, management, and monitoring of Data Guard environments. The prerequisites for using Data Guard Broker include:
The primary and standby databases must run the same version of the Oracle Database server (A): This ensures compatibility between the primary and standby databases and enables seamless role transitions and data synchronization.
Network connectivity to the primary database instance must be defined on the servers hosting the standby database instances (B): Proper network connectivity is essential for communication between the primary and standby databases, allowing for the replication of data and the synchronization of changes.
If any database in the configuration is a RAC database, then the broker configuration files must reside in shared storage accessible by all database instances for all databases in the broker configuration (D): In Real Application Clusters (RAC) environments, shared storage ensures that all instances of the RAC database can access the broker configuration files, facilitating the management of the Data Guard environment across all instances.

NEW QUESTION # 61
Which TWO observations are true about the Far Sync instance?
- A. Can be created using the RMAN DUPLICATE command
- B. Receives redo synchronously from the primary database
- C. Includes a standby control file, password file, data files, standby redo logs, and archive logs
- D. Applies redo received
- E. Can only be created using a series of SQL commands
Answer: B,D
Explanation:
A Far Sync instance is a special kind of Oracle Data Guard configuration that allows synchronous redo transport from a primary database to a remote standby database with minimum impact on the primary database's performance. The Far Sync instance receives redo data synchronously from the primary database (A), then ships it asynchronously to the remote standby database, thus extending zero data loss protection over longer distances and higher network latency environments than would be practical with a synchronous standby alone. The Far Sync instance does not apply the redo data; it just receives and ships it (E).

NEW QUESTION # 62
Which two statements are true regarding Data Guard environments in an Oracle Muti-tenant architecture?
- A. Standby redo log files are required for each pluggable database that is protected with Data Guard.
- B. The Data Guard broker may be used for multi-tenant databases.
- C. PDB_FILE_NAME CONVERT must be set to enable creation of standby databases if they are created on the same host as the primary.
- D. A Data Guard environment with a multi-tenant primary database can operate in any Protection mode.
- E. Different redo transport methods can be configured for different pluggable databases within one Data Guard environment.
Answer: B,D
Explanation:
Oracle Multi-tenant architecture and Data Guard have several interactions, but specific aspects hold true in such environments:
* The Data Guard broker may be used for multi-tenant databases (B): Data Guard Broker simplifies the management and monitoring of Data Guard configurations and is fully compatible with the Oracle Multi-tenant architecture, allowing for easy management of Data Guard configurations that include multi-tenant container databases (CDBs) and their pluggable databases (PDBs).
* A Data Guard environment with a multi-tenant primary database can operate in any Protection mode (E): Data Guard can be configured to operate in Maximum Performance, Maximum Availability, or Maximum Protection mode, regardless of whether the primary database is a multi-tenant database.
This flexibility ensures that Data Guard can meet various data protection and availability requirements in multi-tenant environments.References:

NEW QUESTION # 63
Which TWO are benefits of using Transaction Guard in a Data Guard environment?
- A. It protects against user errors being replicated to standby databases.
- B. It protects against recoverable errors during a planned or an unplanned outage of a primary database.
- C. It provides application continuity by rolling back uncommitted transactions interrupted by a failover or switchover.
- D. It protects against logical corruptions being replicated to standby databases.
- E. It provides application continuity by replaying transactions interrupted by a failover or a switchover
Answer: B,C
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:
* Oracle Database High Availability Overview
* Oracle Real Application Clusters Administration and Deployment Guide
NEW QUESTION # 64
Which two are true about managing and monitoring Oracle container databases in a Data Guard environment using the broker?
- A. If the primary database is a container database, then a logical standby may be a non-container database.
- B. If the primary database is not a container database, then a standby may be a container database.
- C. If the primary database is a container database, then a physical standby may be a non-container database.
- D. All broker actions execute at the root container for container databases.
- E. After a role change, the broker opens all Pluggable databases (pdbb) on the new primary.
Answer: D,E
Explanation:
In the context of Oracle Data Guard and container databases (CDBs) managed by Data Guard Broker:
All broker actions execute at the root container for container databases (D): When using Data Guard Broker to manage a CDB, the actions performed by the broker are executed at the level of the root container. This is because the root container maintains the control and configuration information that applies to the entire CDB, including all of its pluggable databases (PDBs).
After a role change, the broker opens all Pluggable databases (PDBs) on the new primary (E): Following a role transition such as a switchover or a failover, Data Guard Broker ensures that all PDBs within the CDB of the new primary database are opened, which is essential to resume operations of the PDBs without manual intervention.

NEW QUESTION # 65
Your expertise is requested for these customer requirements:
The Data Guard environment must be in maximum protection mode.
Reports must be offloaded to a physical standby database.
There must be no lag between the primary and standby databases that affect the reports produced.
The primary database must be resilient in case of a single network failure.
Which solution is correct for these requirements?
- A. Two standby databases, at least one of them a physical standby with Real-Time Query enabled and the STANDBY_MAX_DATA_DELAY parameter set to zero, receiving redo from the primary with asynchronous transport
- B. Two physical standby databases with Real-Time Query enabled, receiving redo from the primary with the LOG_ARCHIVE_DEST_n attributes SYNC NOAFFIRM to minimize the performance impact on the primary
- C. Two standby databases, at least one of them a physical standby with Real-Time Query enabled and the STANDBY_MAX_DATA_DELAY parameter set to zero, receiving redo from the primary with synchronous transport
- D. One physical standby database with Real-Time Query enabled and STANDBY_MAX_DATA_DELAY parameter set to zero, receiving redo from the primary with synchronous transport
- E. One physical standby database with Real-Time Query enabled, receiving redo from two Far Sync instances that are connected to the primary
Answer: C
NEW QUESTION # 66
Which THREE are true about using flashback database in a Data Guard environment?
- A. When a flashback database operation is performed on a primary database, a physical standby database is also flashed back automatically.
- B. When a flashback database operation is performed on a primary database, a logical standby database is also flashed back automatically.
- C. It may be used to flash back a physical standby that receives redo from a far sync instance.
- D. It may not be used to flash back a primary database after a failover to a physical standby.
- E. You can use it when real-time apply is enabled in case the phylt may not be used to flash back a primary database after a failover to a logical standby.
- F. You can use it when real-time apply is enabled in case the physical standby suffers from logical corruption.
Answer: C,D,F
Explanation:
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 # 67
Examine the Data Guard configuration:
Which three will be true after a successful failover to Cats?
- A. Dogs will be in the disabled state and has to be manually reinstated.
- B. Sheep will be in the disabled state.
- C. Sheep will be in the enabled state.
- D. The configuration will be in Maximum Performance mode.
- E. The configuration will be in Maximum Availability mode.
Answer: A,C,E
Explanation:
After a successful failover to the 'cats' database in a Data Guard configuration:
* B: Sheep, being another standby database, would typically remain in the enabled state unless specifically disabled or if there was a configuration issue.
* D: Dogs, which was the primary database prior to failover, will be in a disabled state as part of the failover process. Manual intervention is required to re-establish 'dogs' as a standby database or to return it to the primary role through another role transition.
* E: If the configuration was in Maximum Availability mode before failover, it would remain in this mode after failover, provided all settings were properly configured and no changes were made to the protection mode.
Option A is incorrect because failover does not automatically change the protection mode to Maximum Performance. The protection mode remains as it was prior to the failover unless manually altered.
References: The behavior of Oracle Data Guard during failover and the resulting configuration state is described in the Oracle Data Guard Broker documentation.
