Oracle 1z1-076 Prüfungsplan:

Thema
Einzelheiten

Thema 3

Enhanced Client Connectivity in a Data Guard Environment: This topic focuses on enhancing client connectivity in a Data Guard setup and implementing failover procedures for seamless client redirection. It also covers application continuity to ensure uninterrupted operations during role transitions.

Thema 4

Monitoring a Data Guard Broker Configuration: The topic covers the use of Enterprise Manager and DGMGRL to monitor Data Guard configurations and explains the various data protection modes available.

Thema 5

Backup and Recovery Considerations in an Oracle Data Guard Configuration: In this topic, Backup and recovery procedures in a Data Guard configuration are discussed, including RMAN backups, offloading to physical standby, and network-based recovery.

Thema 6

Oracle Data Guard Basics: This topic covers the essential architecture and concepts of Oracle Data Guard. It includes sub-topics such as the physical and logical standby database comparison, benefits of Data Guard, and its integration with multi-tenant databases.

Thema 7

Creating a Logical Standby Database: This topic guides users through the process of creating and managing a logical standby database, including SQL Apply filtering.

Thema 8

Performing Role Transitions: Here, the concept of database roles is explained, along with the steps for performing switchovers, failovers, and maintaining physical standby sessions during role transitions.

Oracle Database 19c: Data Guard Administration 1z1-076 Prüfungsfragen mit Lösungen (Q12-Q17):

12. Frage
Examine the procedure that you plan to execute on your logical standby:
SQL> EXECUTE DBMS_LOGSTDBY.SKIP(stmt => 'DML', schema_name => 'HR', object_name => 'EMPLOYEE'); What is a prerequisite for execution of this procedure?

A. Stop redo transport to the logical standby database.
B. Change the redo transport mode if necessary to ASYNC.
C. Execute the DBMS_LOGSTDBY.APPLY_SET procedure to record errors that might cause SQL Apply to stop.
D. Stop SQL Apply on the logical standby database.

Antwort: D

13. Frage
Your current Data Guard environment consists of:
A primary database containing no abstract data types used for user tables.
Two separate remote physical standby databases used for reporting.
Examine these requirements for adding a new standby database to this Data Guard environment:
The new standby database must provide a disaster recovery solution.
There must be minimal additional performance overheads on the primary database.
The new standby database may require additional indexes and materialized views not present in the primary.
New tables or schemas may be required in the standby database that are not present in the primary.
What would you recommend to fulfill these requirements?

A. A logical standby database with synchronous redo transport and SQL apply on.
B. A physical standby database with asynchronous redo transport and Real-Time Query enabled.
C. A logical standby database with asynchronous redo transport and SQL apply on.
D. A physical standby database with synchronous redo transport and Real-Time Query enabled.
E. A logical standby database with synchronous redo transport and redo apply on.

Antwort: C

14. Frage
Your Data Guard environment consists of these components and settings:
A primary database supporting an OLTP workload
A remote physical standby database
Real-time query is enabled
The redo transport mode is set to SYNC
The protection mode is set to Maximum Availability
Which two statements are true regarding the DelayMins database property for the standby database?

A. It specifies a delay before the primary ships redo to the standby destination having DelayMins set.
B. It can only be enabled for a configuration in Maximum Performance mode.
C. It allows logical corruptions on the primary to be recovered by using the physical standby database.
D. It allows user errors on the primary to be recovered by using the physical standby database.
E. It can only be enabled for a configuration in Maximum Availability mode.
F. It enables you to bypass the default network timeout interval specified for the standby redo transport destination.

Antwort: C,D

15. Frage
Which THREE statements are true........ open in real time query mode, which becomes a new.

A. All current buffers can be retained.
B. Sessions that are using database links
C. Sessions that have long running queries can be retained.
D. User sessions can be retained.
E. User sessions and Current Buffers are maintained by default.
F. All sessions are disconnected and all

Antwort: A,D,F

Begründung:
When a physical standby database is opened in real-time query mode, which may be referred to as real-time apply when using Active Data Guard, certain operations can disrupt ongoing sessions. However, with features like Application Continuity and the proper configuration of initialization parameters such as STANDBY_DB_PRESERVE_STATES, user sessions and current buffers may be preserved during role transitions such as a switchover or failover. Specifically, the STANDBY_DB_PRESERVE_STATES parameter can be set to preserve none, all, or only user sessions during such transitions. This ensures that in-flight transactions are not lost and that users do not experience disruptions during the role transitions of a physical standby database.

16. Frage
Which three statements are true about snapshot standby databases?

A. A logical standby database can be converted into a snapshot standby database.
B. The switchover TO command allows a switchover operation to a snapshot standby database.
C. Tables can be dropped.
D. The FATLOVER TO command results in a transition of a snapshot standby database to the primary role.
E. Tablespaces can be dropped.
F. Tablespaces can be created.

Antwort: C,E,F

Begründung:
A snapshot standby database is a fully updateable standby database that is created by converting a physical standby database into a snapshot standby database. The main characteristics of a snapshot standby database include:
* B: Tablespaces can indeed be dropped in a snapshot standby database because it is updateable and allows all types of DML and DDL operations that do not conflict with the standby role.
* C: Tablespaces can be created in a snapshot standby database for the same reasons that they can be
* dropped; it supports all operations that do not interfere with its standby nature.
* E: Tables can be dropped in a snapshot standby database, as it is a fully updateable standby.
Options A and D are incorrect because 'FAILOVER TO' and 'SWITCHOVER TO' commands are not used with snapshot standby databases in these contexts. A failover converts a standby database into the primary role after the original primary has become unavailable, and is not a reversible role transition. Switchover is a planned role reversal between the primary database and one of its standby databases and is not applicable to snapshot standby databases in the context provided.
Option F is incorrect because a logical standby database cannot be converted into a snapshot standby database directly. A logical standby is used for different purposes such as reporting and querying with real-time data, and its structure is different from a physical standby which can be converted into a snapshot standby.
References: Oracle Data Guard Concepts and Administration guide details the operations allowed on snapshot standby databases and the processes for transitioning between physical, snapshot, and logical standby databases.
