Redo apply continuously streams changes from the source to the target database, ensuring data consistency.

Redo apply replays captured redo information on the target database to bring it to a point-in-time consistent with the source.

Redo apply is not used in ZDM, as data is synchronized through a separate mechanism during the cutover phase.

QUESTION 89
Which of the following statements about DMS configuration is TRUE?

It is a one-time setup that does not need to be revisited.

It requires minimal documentation and can be completed quickly.

It is only necessary for initial database setups.

It should align with both source and target database requirements.

QUESTION 90
Which of the following migration methods represents a primarily logical migration approach?

Migrating using Oracle Database Cloud Service (autonomous)

Migrating with Data Pump Export/Import utilities

Migrating using transportable tablespaces and user accounts

Migrating with RMAN backups and restores on the target OCI instance

QUESTION 91
What is the most likely cause of the ORA-19502 error during an RMAN migration, and how would you address it?

The RMAN repository database is not accessible.

The target database version in OCI is incompatible with the source database.

The RMAN configuration file is corrupt on the source system.

The control file cannot be created on the target database due to missing archive logs.

QUESTION 92
In the context of ZDM with heterogeneous database migration (e.g., migrating from MySQL to Oracle), which of the following tools plays a crucial role in schema conversion and data transformation?

Oracle Data Pump Utility

Oracle GoldenGate Microservices Engine

Oracle Database Migration Service (DMS)

Oracle SQL Developer Data Modeler

QUESTION 93
During a Data Pump import process using impdp, which parameter allows for selective import of specific tables from the export file set?

TABLES=schema_name

REMAP_SCHEMA=source_schema:target_schema

CONTENTSCHEMA=schema_name

FILE=filename.dmp

QUESTION 94
During the Post-Migration phase, which of the following activities is the HIGHEST priority to ensure a successful migration?

Optimizing database performance on the target environment

Performing a basic smoke test to verify basic functionality

Performing a full data validation to identify any inconsistencies

Decommissioning the source database after successful migration

QUESTION 95
Which of the following statements is true regarding patching and maintenance in a Multitenant architecture with Oracle Database on OCI?

Patching the CDB automatically applies the updates to all associated PDBs, simplifying maintenance.

Each PDB requires individual patching, potentially leading to downtime during maintenance windows.

Maintenance operations on the CDB can impact the availability of all PDBs within it.

Oracle Database Cloud Service (autonomous) eliminates the need for manual patching in a Multitenant environment.

QUESTION 96
which of the following tools is most valuable for pre-processing the data before import?

Oracle GoldenGate for ongoing data replication and schema conversion.

Oracle Database Migration Service (DMS) for schema conversion and data transformation.

Oracle SQL Developer Data Pump utility for managing export/import jobs.

Oracle RMAN for backup and recovery of the source database.

QUESTION 97
What must be done before using RMAN to migrate a database using backups in OCI?

The source database must be unregistered.

A valid backup must exist.

All users must be logged out.

The database must be upgraded to the latest version.

QUESTION 98
What are the two crucial prerequisites for successfully utilizing the Unplug/Plug method for MTCD migration?

Automatic Storage Management (ASM) enabled on both source and target databases, and flashback archive on the source.

The source database must be in ARCHIVELOG mode, and the target MTCD requires sufficient storage space for the PDB.

Compatible database versions and disabled supplemental logging on the source database.

User privileges pre-configured for target PDB users and Database Vault enabled on both source and target.

QUESTION 99
Which migration strategy is the most appropriate for a large-scale migration of multiple databases with varying sizes, workloads, and feature requirements to OCI, considering cost-efficiency and operational flexibility?

Migrate all databases to a single, large Autonomous Database instance.

Utilize a combination of Autonomous Database and Database System options in OCI.

Migrate all databases to a single Exadata Cloud Service Database VM.

Perform a homogeneous migration to an OCI Dedicated Region.

QUESTION 100
Which of the following services can be used to migrate an on-premises Oracle database to Oracle Cloud Infrastructure (OCI) with minimal downtime?
