DA0-002 Data Concepts and Environments Practice Question
A large financial institution is implementing a data governance framework to comply with new regulations requiring strict control over sensitive customer data. The data governance committee has identified several domains, including customer master data, transaction data, and risk assessment data. They need to decide on a master data management (MDM) approach that ensures a single, authoritative source of customer information across all systems. However, the current environment has multiple legacy systems with conflicting customer records. The committee is concerned about downtime and business disruption during the transition. Which MDM approach best balances data consistency with minimal operational impact?
⚠ Common exam trap
Watch out — candidates often confuse Registry MDM with Consolidation MDM, assuming that a single authoritative source requires physical data movement, when in fact a virtual registry can achieve the same goal with minimal operational impact.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Registry MDM, which creates a virtual view by linking records without moving data.
Registry MDM is correct because it creates a virtual, unified view of customer data by linking records from multiple legacy systems via a registry index, without physically moving or consolidating data. This approach ensures a single authoritative source of customer information while avoiding downtime and business disruption, as the underlying systems remain unchanged and operational during the transition.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Registry MDM, which creates a virtual view by linking records without moving data.
Why this is correct
Correct: Registry avoids disruption by leaving data in place and creating a unified index.
- ✗
Centralized MDM, which replaces all systems with one central master system.
Why it's wrong here
Incorrect: Centralized MDM is highly disruptive and requires full migration.
- ✗
Consolidation MDM, which merges all customer data into a single physical hub.
Why it's wrong here
Incorrect: Consolidation requires data migration and can cause downtime.
- ✗
Coexistence MDM, which maintains multiple masters with synchronization.
Why it's wrong here
Incorrect: Coexistence does not enforce a single source of truth.
