질문 # 59
Which three statements are true about snapshot standby databases?

A. A resize command to extend the size of a datafile in the snapshot standby database, which was created in the primary database, will succeed.
B. A resize command to reduce the size of an empty datafile in the snapshot standby database, which was created in the primary database, will succeed.
C. A resize command to extend the size of a datafile in the snapshot standby database, which was created in the snapshot standby database, will succeed.
D. A resize command to reduce the size of an empty datafile in the snapshot standby database, which was created in the physical standby database, will succeed.
E. A resize command to reduce the size of an empty datafile in the snapshot standby database, which was created in the snapshot standby database, will succeed.

정답：A,C,E

질문 # 60
Your Data Guard environment has two remote physical standby databases.
Client applications use the local naming method to connect to the primary database instance.
You want applications to automatically connect to the new primary database instance in case of a switchover or a failover.
Which set of actions will fulfill this requirement?

A. Set DB_NAME and DB_UNIQUE_NAME identically on all databases; modify the connection descriptors on client applications to include all the standby hosts and connect to the database instance using that service name.
B. Set the LOCAL_LISTENER parameter for all the database instance to register services with the default listener on the primary database host.
C. Create a database service on the primary database that is started automatically by a trigger, when the database role is PRIMARY; modify the connection descriptors used by client applications to include all the standby hosts and connect to the database instance using that service name.
D. Set the INSTANCE NAME parameter identically on all databases; modify the connection descriptor on client applications to include all the standby hosts and connect to the database instance using that service name.

정답：C

설명：
For seamless client redirection in a Data Guard environment, the following steps should be taken:
* Create a database service on the primary database that is started automatically by a trigger when the database role is PRIMARY (B): This ensures that the service is only available on the primary database and is automatically started after a role transition due to switchover or failover.
* Modify the connection descriptors used by client applications to include all the standby hosts and connect to the database instance using that service name (B): Client applications use the connection descriptors that include all potential primary hosts (i.e., the current primary and all standbys). This enables clients to connect to whichever database is currently acting as the primary using the service name.References:

질문 # 61
Which three statements are true about snapshot standby databases?

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

정답：B,C,F

설명：
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.

질문 # 62
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?

정답：A

설명：
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.

질문 # 63
Which THREE steps are prerequisites for the creation of a physical standby database on a separate server using the RMAN active database duplication method?

A. Put the primary database into archivelog mode.
B. Establish user equivalence for the database software owner between the primary host and standby host.
C. Configure Oracle Net connectivity on the primary host to the standby database instance.
D. startup nomount the standby database instance.
E. Set the DB_UNIQUE_NAME parameter on the primary database to a different value than that of the DB_NAME name parameter.

정답：B,C,D

설명：
Creating a physical standby database using RMAN active database duplication requires certain prerequisites to ensure a successful and seamless operation:
Configure Oracle Net connectivity on the primary host to the standby database instance (A): Proper Oracle Net connectivity between the primary and standby servers is essential for communication and data transfer during the duplication process. Oracle Net services provide the network foundation for Oracle Database, Oracle Net Listener, and Oracle applications.
Establish user equivalence for the database software owner between the primary host and standby host (B): User equivalence ensures that the user who owns the Oracle Database software on the primary server has the same privileges on the standby server. This is crucial for RMAN to perform operations on both servers without encountering permission issues.
Startup nomount the standby database instance (C): The standby database instance needs to be started in the NOMOUNT stage before the duplication can begin. This prepares the environment for creating the control file and restoring the database without mounting it, which is a necessary step in the RMAN duplication process.
