XDR-Analyst Alert Lifecycle And Incident Correlation Practice Question
During incident triage, an analyst notices that two completely separate attacks on different endpoints were merged into a single incident by Cortex XDR. What is the underlying reason for this over-correlation?
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
✓
Shared common identifiers such as a NAT gateway IP address within the correlation window
Over-correlation typically occurs when disparate alerts share a common indicator (such as a shared NAT gateway IP address or a generic proxy server) within the same time window, tricking the stitching engine.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
All alerts were manually starred by an analyst
Why it's wrong here
Starring does not trigger event grouping or merging.
- ✗
The incident scoring threshold was set too low
Why it's wrong here
Scoring thresholds rank severity; they do not dictate alert stitching.
- ✗
Featured fields were configured to group by IP subnet
Why it's wrong here
Featured fields do not alter grouping logic.
- ✓
Shared common identifiers such as a NAT gateway IP address within the correlation window
Why this is correct
Shared infrastructure like NAT gateways can cause the engine to falsely stitch unrelated activity.
