XDR-Analyst Alert Lifecycle And Incident Correlation Practice Question
While investigating an alert in Cortex XDR, an analyst notices that a network-layer alert and an endpoint-layer alert have not been stitched into the same incident despite sharing the same internal IP address and user account. What is the most likely cause of this behavior?
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 time delta between the endpoint and network events exceeds the stitching correlation window
Data stitching relies on consistent identity and endpoint mapping. If the time window between events exceeds the stitching threshold or identifiers like MAC/hostname do not match correctly, stitching may fail.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The incident score was manually overridden to low
Why it's wrong here
Severity scoring does not prevent raw alert stitching.
- ✗
Alert starring was disabled on the network data source
Why it's wrong here
Starring is a manual/bookmark feature and does not impact stitching.
- ✗
Featured fields were not configured for the network logs
Why it's wrong here
Featured fields affect table visibility, not data stitching.
- ✓
The time delta between the endpoint and network events exceeds the stitching correlation window
Why this is correct
Cortex XDR enforces time-based thresholds for stitching multi-source telemetry.

Access Control Model Comparison
| Model | Acronym | Who Controls Access? | Best For |
