SNOW-CSA Database Administration and CMDB Practice Question
An organization is planning to implement CMDB for a large-scale environment with multiple data sources. They need to ensure that the most trustworthy data source takes precedence when conflicts occur. Which feature should they use?
⚠ Common exam trap
A common mix-up: candidates confuse the Identification & Reconciliation engine (which performs the conflict detection) with the Data Source Priority feature (which dictates which source wins), leading them to select Option A instead of D.

Correct answer & explanation
✓
Data Source Priority
Data Source Priority (Option D) is the correct feature because it allows administrators to define a hierarchy of data sources in the CMDB, ensuring that when multiple sources provide conflicting attribute values for the same CI, the source with the highest priority (lowest numeric value) is trusted and its data is used. This directly addresses the requirement to make the most trustworthy data source take precedence in a large-scale, multi-source environment.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Identification & Reconciliation engine
Why it's wrong here
This engine handles CI identification, not source priority.
- ✗
Reconciliation
Why it's wrong here
Reconciliation resolves conflicts but does not set source priority by itself.
- ✗
Set source precedence in the CI class manager for each CI
Why it's wrong here
Source precedence is not set per CI but globally.
- ✓
Data Source Priority
Why this is correct
This feature allows setting precedence for data sources.
