최신 Oracle Database 19c 1z1-076 무료샘플문제 (Q25-Q30):

질문 # 25
You are planning to perform block comparison using the dbms comp package:

Which TWO statements are true?

A. Logical standby databases can be the target database for the dbms_dbcomp.dbcomp procedure.
B. You can monitor the progress of an ongoing block comparison operation by querying VS SES SION_LONGOPS.
C. The databases should be at least mounted before block comparison.
D. It requires that the DB_LOST_WKITE_protect initialization parameter be enabled.
E. It can be used to detect lost writes and inconsistencies between the primary database and the cascaded standbys.

정답：B,C

설명：
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.

질문 # 26
Which THREE statements are true about snapshot standby databases?

A. FLASHBACK DATABASE must be manually enabled on a physical standby database before converting it into a snapshot standby database.
B. A snapshot standby database may be opened read-write.
C. A snapshot standby database may be opened read-only.
D. FLASHBACK DATABASE is enabled automatically on a physical standby database as part of the conversion into a snapshot standby database, if not already enabled.
E. FLASHBACK DATABASE is enabled automatically on a snapshot standby database after converting it from a physical standby database if not already enabled.
F. A snapshot standby database can have Real-Time apply enabled.

정답：B,D,E

설명：
Snapshot standby databases are a feature of Oracle Data Guard that allows a physical standby database to be temporarily converted into a read-write database for testing or other purposes. The true statements about snapshot standby databases are:
FLASHBACK DATABASE is enabled automatically on a snapshot standby database after converting it from a physical standby database if not already enabled (B): When a physical standby is converted to a snapshot standby, FLASHBACK DATABASE is automatically enabled to allow the database to be easily reverted back to its original state.
FLASHBACK DATABASE is enabled automatically on a physical standby database as part of the conversion into a snapshot standby database, if not already enabled (C): As part of the conversion process, FLASHBACK DATABASE is turned on to ensure that changes made while the database is in snapshot standby mode can be undone.
A snapshot standby database may be opened read-write (E): Once a physical standby is converted to a snapshot standby, it can be opened for read-write operations, allowing for testing and other tasks that require a writable database.

질문 # 27
A Data Guard environment has this configuration and these attributes:
The primary database prima is in the local region.
A physical standby database physt1 is in the local region.
A physical standby database physt2 is in a remote region.
The primary ships redo to physt1.
physt1 ships redo to physt2.
physt1 and physt2 have Real-Time Query enabled.
A sequence has been created with this SQL statement in the primary database:
CREATE SEQUENCE a NOCACHE SESSION;
Which TWO statements are TRUE?

A. physt2 will no longer receive redo if physt1 becomes unavailable, unless LOG_ARCHIVE_DEST_n has the ALTERNATE attribute specified on physt1.
B. physt2 will no longer receive redo if physt1 becomes unavailable, unless LOG_ARCHIVE_DEST_n has the ALTERNATE attribute specified on the primary database.
C. The sequence is usable on physt2 if physt1 becomes unavailable, but only if an alternate redo destination has been configured on the primary database.
D. The sequence is usable on physt1 and physt2.
E. The sequence is usable on physt1 but not usable on physt2.

정답：B,D

질문 # 28
Which four factors can influence the rate of SQL apply on a logical standby database?

A. the number of PREPAER processes
B. the size of the undo tablespace on the logical standby database
C. the number of coordinator processes on the standby database instance
D. the number of applier processes
E. the size of the shared pool
F. the number of full table scans performed by SQL apply

정답：A,C,D,F

설명：
The rate of SQL apply on a logical standby database can be influenced by:
* A: The number of PREPARER processes (which seems to be a typographical error and should read as PREPARER or similar) which prepare the redo data for the applier processes.
* B: The number of coordinator processes on the standby database instance which coordinate the SQL apply activities.
* C: The number of full table scans performed by SQL apply since full table scans can be resource-intensive and slow down the apply rate.
* E: The number of applier processes which apply the redo data to the logical standby database.
Option D is incorrect as the size of the undo tablespace on the logical standby database is more likely to affect the SQL apply lag rather than the rate of SQL apply.
Option F is incorrect because the size of the shared pool would typically not influence the rate of SQL apply.
The shared pool is more related to the caching of shared SQL and PL/SQL code and control structures.
References: Oracle's documentation on SQL Apply in Data Guard configurations discusses the factors affecting the performance of SQL Apply operations on logical standby databases.

질문 # 29
You must design an Oracle Data Guard configuration for a DSS database that meets these permanent requirements:
1. Creating and maintaining bitmap indexes should not impact the performance of the primary database.
2. Creating and maintaining materialized views should not impact the performance of the primary database.
Additionally, there are these requirements, only one of which is ever done at any one time:
1. It should be possible to apply designated patches with a minimum amount of downtime.
2. Upgrading to a new database release should be performed with the least possible amount of downtime.
3. New application software releases should be tested against an exact and up-to-date replica of the primary database.
Which configuration meets these requirements with the fewest of databases?

A. a primary database with two logical standby databases
B. a primary database with one physical standby database
C. A primary database with one logical and one physical standby database
D. a primary database with two physical standby databases
E. a primary database with one logical standby database

정답：E

설명：
* Logical standby databases allow the execution of DDL and DML operations, which makes them suitable for maintaining bitmap indexes and materialized views without affecting the performance of the primary database .
* Logical standby databases can be used for performing rolling upgrades and patching with minimum downtime, meeting another requirement .
* They also enable the testing of new application software releases against an up-to-date replica of the primary database, fulfilling the last requirement.
Other configurations involving physical standby databases or combinations of logical and physical standby databases might not meet all the specified requirements as efficiently or with the same level of performance isolation for the primary database.
