MDM Trust Framework and Confidence Scoring 2 — Questions and Answers
Question 1: What is the purpose of 'Validation Trust' in the Informatica MDM Trust Framework?
- To validate user credentials before allowing data updates
- To add bonus trust points when data passes configured validation rules (Correct answer)
- To set the base trust level for a newly registered source system
- To determine the trust level assigned to null or empty field values
Correct answer: To add bonus trust points when data passes configured validation rules
Validation Trust is a bonus added to the base trust score when data from a source system passes the configured validation rules, rewarding higher-quality data contributions.
Question 2: In Informatica MDM, which setting controls whether a source system's data can replace an existing golden record value regardless of comparative trust scores?
- Base Trust
- Validation Trust
- Override (Correct answer)
- Max Trust
Correct answer: Override
The Override setting determines whether a source system's data can replace an existing golden record value regardless of the relative trust scores between competing sources.
Question 3: How is the effective trust score for a field value generally calculated in Informatica MDM?
- Base Trust + Validation Trust - Decay (Correct answer)
- (Base Trust × Validation Trust) / Max Trust
- Max Trust - (Base Trust + Decay)
- Validation Trust × Decay Rate
Correct answer: Base Trust + Validation Trust - Decay
The effective trust score is computed as Base Trust plus any Validation Trust bonus, minus any decay that has accumulated due to data aging since the last update.
Question 4: In the MDM Hub Schema Manager, at which point are trust settings typically assigned to base object columns?
- During the initial Hub Store database installation
- When configuring base objects and defining source system contributions (Correct answer)
- Only after the first full batch load has been completed
- Automatically by the MDM Hub without requiring manual configuration
Correct answer: When configuring base objects and defining source system contributions
Trust settings are configured in the Schema Manager when setting up base objects and defining how each source system contributes to each column, as part of schema design.
Question 5: Which Informatica MDM concept describes selecting the best attribute values from multiple source records to form a single authoritative master record?
- Record Linkage
- Data Profiling
- Survivorship (Correct answer)
- Tokenization
Correct answer: Survivorship
Survivorship is the process where the best values from matched and merged source records are selected—often using trust scores—to form the golden master record.
Question 6: What is the 'Best Version of Truth' (BVOT) in Informatica MDM?
- The source system record with the fewest null values across all fields
- The most recently updated record found in the staging area
- The golden record composed of the highest-trust values from all contributing sources (Correct answer)
- A backup copy of the master record stored in a separate archive table
Correct answer: The golden record composed of the highest-trust values from all contributing sources
The Best Version of Truth is the golden record in Informatica MDM, assembled by selecting the highest-trust field values from all matched and merged source records during consolidation.
Question 7: In Informatica MDM, a source system has Base Trust = 55 and Validation Trust = 25. If Max Trust is set to 70, what is the effective maximum trust score achievable?
- 80
- 55
- 70 (Correct answer)
- 25
Correct answer: 70
Even though Base Trust + Validation Trust = 80, the Max Trust of 70 acts as an absolute ceiling, capping the effective trust score at 70.
