Read the first 7 Trust Framework and Confidence Scoring flashcards as text

  1. What is the effect of setting a high decay rate for a source system's trust configuration in Informatica MDM?

    Answer: The trust score will decrease more rapidly as time passes without a data refresh

    A high decay rate causes the trust score for data from that source to decrease more rapidly over time, making older stale data from that source less likely to survive in the golden record.

  2. When Override is set to TRUE for a source system column trust configuration, what is the expected behavior?

    Answer: Data from this source will always overwrite the existing golden record value regardless of trust scores

    When Override is TRUE, data from that source system replaces the existing golden record value regardless of whether its trust score is higher or lower than the current surviving value.

  3. What is the practical benefit of Trust Score Decay in real-world Informatica MDM implementations?

    Answer: To reduce the influence of stale source data on the golden record over time

    Trust Score Decay reduces the trust score of data that has not been refreshed recently, ensuring stale source data has decreasing influence on the golden record as time passes.

  4. Which Informatica MDM feature allows data stewards to manually override the trust-based survivorship result for a specific field on the golden record?

    Answer: Manual value pinning through Informatica Data Director (IDD)

    Informatica Data Director (IDD) allows data stewards to manually pin a specific value to the golden record, overriding the system-calculated trust-based survivorship result.

  5. What is the primary advantage of the Trust Framework over a simple 'last-write-wins' survivorship strategy in Informatica MDM?

    Answer: It allows multiple source systems to contribute field values based on their configured reliability

    The Trust Framework enables field-level survivorship based on each source system's reliability configuration, ensuring the most trustworthy data from any contributing source wins rather than always defaulting to the most recent update.

  6. In Informatica MDM, what does a 'source system contribution' define in the context of the trust framework?

    Answer: The configured trust parameters governing how a source system's values compete during survivorship

    A source system contribution in Informatica MDM defines the trust parameters—base trust, max trust, validation trust, decay—that govern how values from that source compete during survivorship consolidation.

  7. Which statement correctly describes how Informatica MDM handles trust when a source system provides a null value for a configured column?

    Answer: The behavior depends on the null handling configuration within the column's trust settings

    Informatica MDM provides configurable null handling within trust settings, allowing administrators to define specific behavior—such as ignoring nulls or treating them as valid overrides—when source systems provide empty values.
