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 posture agent failed to connect to the PSN
Why this is correct
If the agent cannot send the report, ISE keeps the status as 'Unknown'.
- ✗
The Client Provisioning policy is misconfigured
Why it's wrong here
This would prevent the agent from even installing or launching.
- ✗
The remediation action is disabled
Why it's wrong here
This would lead to a 'Non-Compliant' status, not 'Unknown'.
- ✗
The authorization rule is incorrect
Why it's wrong here
While possible, the state 'Unknown' usually implies no posture data has reached the server.
