Check the Oracle wallet configuration for proper access to the target database credentials.

Review the RMAN recovery catalog for potential inconsistencies.

NO.23 Which of the following migration methods would be the MOST appropriate for minimizing downtime during peak hours?

Full Database Backup and Restore

Data Pump Export/Import

GoldenGate for continuous availability

User Interface Migration through Oracle Cloud Infrastructure (OCI) Console

NO.24 Which of the following describes ‘logical migration’?

Moving entire database files as-is

Extracting and converting data to a new format

Using replication to synchronize data in real-time

Migrating the database schema and data without physical file movement

25位 When utilizing Oracle Data Guard for ZDM with a standby database, which statement best describes the failover process after completing the initial full data synchronization?

The primary database is switched to read-only mode, and the standby database becomes the new primary with minimal downtime.

The standby database applies the remaining redo generated on the primary during synchronization, then becomes the new primary.

The primary database remains active, while the standby database continues receiving ongoing redo for high availability.

The standby database is manually promoted to primary, requiring an application outage to complete the failover.

NO.26 Which of the following capabilities of ADB is MOST relevant to data security?

ADB offers a variety of preconfigured database versions with security patches applied.

ADB automatically encrypts data at rest and in transit within the OCI cloud environment.

ADB allows granular access control for user pluggable databases (PDBs) within a Multitenant architecture.

ADB integrates seamlessly with Oracle Key Vault for centralized encryption key management.

NO.27 Which of the following considerations when choosing a target database option in OCI is MOST crucial to ensure successful migration and data integrity?

The target database version must be the same as the source database version.

The target database edition (e.g., Standard, Enterprise) must match the source.

The target database character set needs to be compatible with the source data.

The target database storage tier (e.g., high performance, balanced) should be optimized.

NO.28 How should GoldenGate be configured to handle the migration of materialized views and ensure data consistency on the target database?

Disable materialized view refresh on the source database before and after migration.

Migrate materialized views after all other schema objects have been replicated.

Utilize GoldenGate filtering to exclude materialized views from the migration.

Configure GoldenGate to capture DML statements that update underlying tables of materialized views.

NO.29 Which of the following steps is NOT required during ZDM configuration for such a schema?

Refresh materialized views on the standby database before cutover.

Ensure all partitions are online on the standby database.

Set the flashback recovery area size on the standby database to match the source.

Configure supplemental logging for materialized view refresh on the source database.

30位 What is a primary benefit of migrating a database to Oracle Cloud Infrastructure (OCI)?

Reduced database performance

Increased complexity in database management

Enhanced scalability and flexibility

Higher maintenance costs

NO.31 In Zero Downtime Migration, which of the following can be used as a target for the migrated data? (Select all that apply)

Oracle Autonomous Database

On-premises Oracle Database

MySQL Database

Oracle Cloud Infrastructure Database

NO.32 Which of the following considerations should be prioritized to ensure a successful migration and avoid post-migration data inconsistencies?

Optimizing network bandwidth for faster data transfer

Maintaining the order of table creation during the migration process

Disabling referential integrity constraints before migration and re-enabling them afterward

Performing a full database validation post-migration to identify any inconsistencies

NO.33 In a Zero Downtime Migration (ZDM) scenario using Oracle GoldenGate, how does the system ensure data consistency between the source and target databases during the initial data load phase?

GoldenGate automatically validates and corrects data inconsistencies during the load process.

The initial load process involves applying redo generated on the source after the data copy.

Data consistency is guaranteed by replicating the commit order of transactions from source to target.

GoldenGate utilizes checksums and verification techniques to detect and resolve data discrepancies.

NO.34 In a ZDM scenario with a large database, how does partitioning within the source database impact the technical architecture design?

Partitioning requires no changes to the architecture, as GoldenGate can handle all data types.

Partitioning simplifies the architecture by reducing the number of redo apply servers needed.

Partitioning enables a rolling cutover strategy by migrating individual partitions sequentially.

Partitioning increases the complexity of the architecture by requiring additional staging databases.

NO.35 which of the following considerations is NOT directly relevant for seamless integration?

Compatibility of source and target database versions within the same Container Database (CDB)

Resource allocation and isolation between migrated databases within the CPDB

User and schema management strategies for access control across migrated databases

Network configuration for secure communication between on-premises and the OCI multi-tenant environment

NO.36 During ZDM with Oracle Data Guard, which component within the technical architecture facilitates the synchronization of captured data changes between the source and target databases?

Oracle Data Pump Utility

Oracle GoldenGate Delivery process

Oracle Standby Redo Apply server

Oracle Database Automatic Storage Management (ASM)

NO.37 Which of the following statements about RMAN and TTS is MOST accurate?

RMAN can directly convert a source tablespace to a TTS for migration.

You can create a TTS from a backup set generated using RMAN incremental backups.

RMAN can be used to perform a block-level incremental backup for migration using TTS.

Migration with TTS requires creating a separate control file for the TTS on the target database.

第38位 What is the purpose of database link creation in Zero Downtime Migration?

To connect the target database to external systems

To perform security audits

To configure user roles

To facilitate data transfer between source and target databases

NO.39 Which consideration is most relevant for maintaining Oracle Database Archive Logging functionality when migrating to a target database in OCI?

The target database needs to be configured with the same archive log retention settings as the source.

You need to enable Oracle Database Automatic Data Warehousing (ADW) on the target database.

OCI Object Storage can be used to archive redo logs generated on the target database in OCI.

Enabling Flashback Database on the target database will automatically manage archive logs.
