IBM Assessment: High Volume Data Migration v4 Practice Exam: Test Your Knowledge 2025

During the initial assessment phase of a high-volume data migration project, what is the PRIMARY purpose of conducting a data profiling exercise?

Which IBM tool is specifically designed for continuous data replication and synchronization between heterogeneous databases during a migration project?

What is the primary benefit of implementing a data quality framework BEFORE executing a high-volume data migration?

During a large-scale migration, the data transfer rate suddenly drops by 60%. What should be the FIRST troubleshooting step?

In a phased migration approach, what is the main advantage of using a 'trickle migration' strategy?

A financial institution is migrating 50TB of transactional data from an on-premises Oracle database to a cloud-based Db2 environment. They require zero data loss and minimal downtime. Which migration strategy should be recommended?

When using IBM Data Replication for a heterogeneous database migration, what is the purpose of the 'subscription' component?

What is the PRIMARY advantage of using IBM DataStage for complex data transformations during a migration project?

A migration process is experiencing frequent deadlocks on the target database. What is the MOST likely cause and solution?

In a data migration project, what is the purpose of implementing a 'reconciliation report' process?

When migrating a database with complex referential integrity constraints, what is the recommended sequence for data migration?

Which IBM tool component is specifically used for schema conversion and assessment when migrating between different database platforms?

During high-volume data migration, the target database transaction logs are growing rapidly and consuming all available storage. What is the BEST immediate action?

What is the primary purpose of implementing a 'data lineage' tracking system during a complex migration project?

An organization is planning to migrate 200TB of historical data from multiple legacy systems to a single consolidated platform. Initial estimates show the migration will take 6 months at current transfer rates. What combination of strategies would BEST accelerate the migration while maintaining data integrity?

In a heterogeneous database migration using IBM InfoSphere Data Replication, the replication is experiencing increasing latency over time. The source database has high transaction volume with frequent updates to the same records. What is the MOST effective solution?

A migration project requires transforming denormalized source data into a normalized target schema while maintaining referential integrity. The source system has 500 million records with embedded repeating groups. What is the MOST appropriate approach?

During performance testing of a migration process, you observe that CPU utilization on the target database server is only 30%, disk I/O is at 40%, but the migration is still slow. Network utilization shows 95% capacity. What is the PRIMARY bottleneck and solution?

An enterprise is migrating a mission-critical database that must maintain sub-second consistency between source and target during the cutover phase. The system processes 50,000 transactions per minute. Which architecture pattern and IBM tool combination is MOST appropriate?
