CIS-DF Configuration Practice Question
When configuring identification rules for a custom CI class via the CI Class Manager, an administrator includes multiple criteria attributes. How does the Identification and Reconciliation Engine (IRE) process these criteria?
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
✓
The IRE evaluates criteria attributes as an AND condition within the criterion, requiring all specified attributes to match.
The IRE evaluates criteria within an identification rule as an AND operation; all specified attributes in an identification criterion must match for the CI to be identified as an existing record.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Criteria attributes are ignored unless a Discovery source is explicitly named in the payload.
Why it's wrong here
Identification rules apply to all integration payloads processed through the IRE, regardless of discovery source unless filtered by rule scope.
- ✗
The IRE randomly selects one attribute to perform the lookup based on payload weight.
Why it's wrong here
The IRE does not randomly select attributes; it follows strict evaluation order defined in the rule.
- ✗
The IRE evaluates attributes as an OR condition, matching on any single attribute present in the payload.
Why it's wrong here
Within a single criterion, attributes operate as an AND condition. Separate criteria entries act as sequential fallback steps (OR).
- ✓
The IRE evaluates criteria attributes as an AND condition within the criterion, requiring all specified attributes to match.
Why this is correct
All attributes listed inside a single identification criterion must match the target CI for identification to succeed.
