Data 360 Consultant Identity Resolution Practice Question
A consultant is configuring identity resolution and needs to ensure that when multiple sources provide a customer's birthdate, the oldest recorded birthdate is retained on the unified profile. Which reconciliation rule should be used?
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
✓
Source Sequence configured with the oldest system prioritized first.
While standard reconciliation rules include Most Recent, Source Sequence, Highest Frequency, and Longest String, specific attribute survivorship needs or custom logic may require understanding standard options. If oldest date is required, consultants should note that 'Most Recent' is standard, but let's evaluate the available choices.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Longest String
Why it's wrong here
Longest string evaluates character length, which is irrelevant for date values.
- ✗
Highest Frequency
Why it's wrong here
Highest Frequency picks the most common date, which does not guarantee it is the oldest.
- ✓
Source Sequence configured with the oldest system prioritized first.
Why this is correct
When dealing with chronological data where standard Most Recent isn't appropriate, Source Sequence allows explicit prioritization based on known system reliability (e.g., legacy master system).
- ✗
Most Recent
Why it's wrong here
Most Recent would select the newest date, which is the opposite of the requirement.
