Ability to vertically scale compute and storage resources independently.

Integration with Oracle Database Exadata Cloud Service for high-performance processing.

NO.72 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.73 What is a primary advantage of using GoldenGate for database migration?

It supports only offline migrations.

It is limited to Oracle databases only.

It requires less configuration than other tools.

It provides near real-time data replication.

NO.74 In a ZDM scenario with a large database and high transaction volume, which of the following techniques can help mitigate potential performance issues during cutover?

Enabling archive logging on the source database before starting the migration.

Performing a full database export and import using Data Pump before initiating ZDM.

Utilizing supplemental logging on the target database to capture additional information for troubleshooting.

Employing a staged cutover approach, migrating schemas or partitions sequentially.

NO.75 Which OCI target database option is the most cost-efficient choice for a development database with frequent schema changes?

Database System Class with Bare Metal

Autonomous Database (ADB) Single Instance

Autonomous Database (ADB) Free Tier

Exadata Cloud Service

NO.76 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.77 How would you troubleshoot and resolve the RMAN-03113: insufficient privilege error during an RMAN convert operation?

Verify the RMAN configuration file for correct target database connection details.

Grant the SYSDBA role to the RMAN user on the target database.

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

Review the RMAN recovery catalog for potential inconsistencies.

NO.78 While configuring ZDM with Oracle Database Migration Service (DMS) for a schema-only migration, which of the following options should be disabled within the DMS configuration?

Data type mapping between source and target databases.

Online schema conversion during data migration.

Post-migration schema validation on the target database.

User account creation for accessing the target database.

NO.79 When designing the ZDM technical architecture with Oracle Data Guard, how does the standby database ensure data consistency with the source during ongoing data replication?

The standby database applies redo directly from the source database using network connections.

The standby database receives archived redo logs from the primary and applies them sequentially.

The standby database maintains a real-time copy of the source database using Oracle Streams technology.

The standby database periodically synchronizes with the source through snapshots and incremental updates.

NO.80 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.81 Which of the following is a critical factor to consider when configuring Zero Downtime Migration?

End-user training requirements

Number of users accessing the database

Size of the source database only

Compatibility of the source and target databases

NO.82 which of the following statements is NOT a valid prerequisite for the source database?

The source database must be compatible with the target MTCD container database version.

The source database must have Automatic Storage Management (ASM) enabled.

The source database must be in ARCHIVELOG mode.

The source database must use the same character set as the target MTCD.

NO.83 During a Data Pump import operation with a large dataset, which parameter can be used to optimize performance and minimize downtime?

Setting the NETWORK_TIMEOUT parameter to a higher value.

Configuring the STATISTICS parameter to gather detailed import statistics.

Enabling the ROWGRANULARITY parameter for row-level import processing.

Utilizing the TRANSPORT_DATA parameter to include table data during import.

NO.84 During the Unplug/Plug migration process, what happens after the read-only snapshot (PDB) is created within the MTCD?

The source database is shut down, and its data files are physically copied to the new PDB.

The source database remains operational, and periodic refreshes are performed to update the target PDB.

Users are automatically granted access to the newly created PDB within the MTCD.

The Unplug/Plug method doesn’t require any manual intervention after the initial snapshot creation.

NO.85 In the context of ZDM with a rolling cutover strategy, which workflow element dictates the order in which data partitions are migrated to the target database?

The chosen migration tool automatically determines the optimal partition sequence.

User-defined partition dependencies specify the order for migration.

The size and activity level of each partition influence the migration sequence.

The ZDM process prioritizes migrating less frequently accessed partitions first.

NO.86 Which OCI target database option is most suitable for cost-efficiency and minimal management overhead?

Virtual Machines (VMs) running Oracle Database software

Dedicated Database instances with pay-as-you-go billing

Autonomous Database with Automatic Workload Management (AWM)
