Oracle Database 19c: Data Guard Administration Sample Questions (Q76-Q81):NEW QUESTION # 76
Which TWO statements are true about Far Sync instances?
  • A. They work in Maximum Availability mode.
  • B. They do not work with Snapshot Standby databases.
  • C. They do not work with Logical Standby databases.
  • D. They work in Maximum Protection mode.
  • E. They work in Maximum Performance mode.
Answer: C,E

NEW QUESTION # 77
You must configure flashback database for your Oracle 19c databases that will be part of a Data Guard Broker configuration.
The databases are all in ARCHIVELOG mode.
You will execute the SQL statement:
ALTER DATABASE FLASHBACK ON;
Which three are true concerning this command?
  • A. It will execute successfully while an Oracle 19c primary database is mounted.
  • B. It will execute successfully while an Oracle 19c primary database is open.
  • C. If executed successfully on an Oracle 19c primary database, flashback will also be enabled on all logical standby databases that are part of the configuration.
  • D. It will execute successfully on an Oracle 19c logical standby database while SQL apply is active.
  • E. It will execute successfully on an Oracle 19c physical standby database while Real Time Query is active.
  • F. If executed successfully on an Oracle 19c primary database, flashback will also be enabled on all physical standby databases that are part of the configuration.
Answer: A,B,D
Explanation:
The command ALTER DATABASE FLASHBACK ON; enables the Flashback Database feature, which provides a way to quickly revert an entire Oracle database back to a previous point in time. This command can be executed while an Oracle 19c primary database is either open (option A) or mounted (option B). It is also applicable to an Oracle 19c logical standby database while SQL Apply is active (option E). However, it's important to note that enabling Flashback Database on the primary does not automatically enable it on all associated standby databases, whether they are physical or logical. Each database in a Data Guard configuration must have Flashback Database explicitly enabled if desired. Real Time Query being active on a physical standby does not directly relate to the ability to execute this command on the standby. References:
The explanation is based on Oracle's concepts for Flashback Technology and Data Guard configurations as detailed in the Oracle Database Backup and Recovery User's Guide and the Oracle Data Guard Concepts and Administration guide.

NEW QUESTION # 78
Your Data Guard environment contains a primary database and three standby databases with these attributes:
1. prod : Primary database
2. prod_prq : Physical standby database with real-time query enabled used by reporting applications
3. prod_lsby: Logical standby database used by DSS
4. PROD_SSBY: Snapshot standby database used for Real Application Testing Which TWO can be used to prevent clients from connecting to the wrong database instance?
  • A. Create database services for each database and use event triggers to make sure that services are activated only when the database is in the correct role.
  • B. Create role based services with the si vet] utility when using clusterware for Oracle RAC databases or Oracle Restart for single instance Oracle databases.
  • C. Create database services on each of the standby databases, start the services, and add connection descriptors on the clients to connect to those services.
  • D. Establish Oracle Net connectivity to the primary database instance from all the standby database instances.
  • E. Create a static service for each of the databases, register it with the local listener of each database instance, and add connection descriptors on clients to connect to those services.
Answer: A,C
Explanation:
Creating dedicated database services for each database instance (Option D) and utilizing event triggers to manage these services based on the role of the database (Option E) ensure that clients connect to the appropriate database instance based on its current role and state. This approach leverages the flexibility and control provided by Oracle Net services and database event management to direct client connections to the suitable primary or standby instance, enhancing the overall robustness and reliability of the Data Guard environment. References: Based on Oracle Database 19c best practices for managing connectivity and services in a Data Guard setup, including the use of role-based services and event-driven service management.

NEW QUESTION # 79
You created the PRODSBY1 physical standby database for the PROD primary database using gql and RMAN. You are planning to create a Data Guard Broker configuration. You execute the command:

Which three statements are true regarding the execution of the command?
  • A. The Data Guard Broker configuration files is automatically created in the destinations specified by the DG_BROKER_CONFIG_FILEn initialization parameters on the primary database.
  • B. The PRODSBYI standby database is automatically added to the configuration if Oracle Net connectivity to the PRODSBYl database instance is defined on the primary host.
  • C. The PRODSBY1 standby database is automatically added to the configuration if DG_BROKER_START is TRUE for PRODSBYl.
  • D. The command will execute successfully only if Oracle Net connectivity to the PROD and PRODSBYl database instances are defined on the primary host.
  • E. The command will execute successfully only if Oracle Net connectivity to the PROD database instance is defined on the primary host.
  • F. The command will execute successfully only if the DG_BROKER_START initialization parameter is set to TRUE for the PROD database instance.
Answer: A,E,F
Explanation:
The command executed (CREATE CONFIGURATION 'DGConfig' AS PRIMARY DATABASE IS 'PROD' CONNECT IDENTIFIER IS PROD;) is used to create a Data Guard Broker configuration named 'DGConfig'. The successful execution of this command depends on several conditions:
A: The DG_BROKER_START parameter must be set to TRUE on the primary database to start the Data Guard Broker processes. Without the broker processes running, the configuration cannot be created.
D: Oracle Net connectivity to the PROD database instance must be established on the primary host. This is because the Data Guard Broker requires network accessibility to communicate with the primary database and manage the configuration.
E: When the configuration is created, the Data Guard Broker configuration files are indeed automatically created in the locations specified by the DG_BROKER_CONFIG_FILEn parameters on the primary database.
It's important to note that the command will not automatically add the PRODSBY1 standby database to the configuration (thus B and C are not correct), and there is no requirement for the standby database to have Oracle Net connectivity defined on the primary host for the execution of this command (making F incorrect as well).

NEW QUESTION # 80
Your Data Guard environment has one physical standby database using Real-Time Query. Two sequences have been created by these SQL statements:

Neither sequence has been used since being created.
Session 1 connects to the primary database instance and issues these two SQL statements:
SELECT a.nextval FROM DUAL; SELECT b.nextval FROM DUAL;
Then session 2 connects to the physical standby database instance and issues the same SQL statements. Which output will be seen for session 2?
Then session 2 connects to the physical standby database instance and issues the same SQL statements. Which output will be seen for session 2?
  • A.
  • B.
  • C.
  • D.
Answer: C
Explanation:
In Oracle, a sequence created with the GLOBAL keyword is available and can produce values across all sessions and instances. However, a sequence created with the SESSION keyword is only specific to the session it was created in. When the NEXTVAL is called for a sequence, it will increment according to the sequence's properties set during its creation.
Given the sequence creation statements and the actions performed:
* The a sequence is global, which means it is available across the entire database, including the standby database with Real-Time Query enabled. So, when session 2 calls a.nextval, it will get the next value in the sequence, which is 21 since session 1 already retrieved 1.
* The b sequence is session-specific, so when session 2 calls b.nextval, it will get the value 1 because for this new session on the standby, this is the first time the sequence is being accessed.
Therefore, the output for session 2 will be a output as 21 and b output as 1, which corresponds to Option C.
References: The behavior of global vs session-specific sequences is outlined in Oracle's SQL Language Reference under the CREATE SEQUENCE statement documentation.
