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
✓
Precedence rules can be configured to allow specific data sources to update designated attributes while blocking others.
Precedence rules operate hierarchically, can be customized per class, and rely on exact discovery source string matching.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Data Source Precedence rules are managed directly within the System Log table.
Why it's wrong here
Precedence rules are managed in CI Class Manager, not the System Log.
- ✓
Precedence rules can be configured to allow specific data sources to update designated attributes while blocking others.
Why this is correct
Precedence rules give granular control over which sources win specific attributes.
- ✗
Precedence rules automatically apply to legacy transform maps that do not use the IRE.
Why it's wrong here
Legacy transform maps bypass the IRE and therefore do not respect Data Source Precedence rules.
- ✓
Child classes inherit Data Source Precedence rules from parent classes unless explicitly overridden.
Why this is correct
Inheritance applies through the CI class hierarchy, allowing child classes to inherit or override parent precedence rules.
- ✓
If no specific precedence rule is defined for an attribute, the IRE falls back to default precedence behavior.
Why this is correct
When explicit rules are absent, standard default system precedence logic applies.
