SCAZT Visibility And Assurance Practice Question
You notice an alert in SecureX indicating 'Identity Correlation Failure'. What is the most common reason for this when integrating Cisco Secure Endpoint and Cisco Identity Services Engine (ISE)?
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
✓
Inconsistent time synchronization (NTP) between ISE and the Endpoint
Identity correlation requires a common identifier (like IP address or MAC) and time-synchronization; discrepancies often stem from mapping failures due to time offsets or missing context exchange.
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 ISE node is in standby mode
Why it's wrong here
Standby nodes should still process authentication logs if configured correctly.
- ✗
The SecureX browser extension is disabled
Why it's wrong here
The extension is a UI tool and not part of the backend correlation service.
- ✓
Inconsistent time synchronization (NTP) between ISE and the Endpoint
Why this is correct
Correlation engines rely on timestamps; if the systems are not synced via NTP, the events cannot be mapped to the same identity window.
- ✗
The endpoint is not joined to the domain
Why it's wrong here
While it affects data, it does not specifically break the correlation engine itself.
