PCNSE Troubleshoot Practice Question
After upgrading Panorama to a newer version, a configuration push to a managed firewall fails with the error 'Commit failed: template validation error.' Which of the following should be checked first?
⚠ Common exam trap
A common mix-up: candidates assume a 'validation error' is due to permissions or connectivity, but in the context of a Panorama commit, it almost always points to a version mismatch between Panorama and the managed firewall.
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
✓
Verify that the firewall's PAN-OS version is supported by the Panorama version.
The 'template validation error' during a commit indicates that the configuration templates being pushed are incompatible with the target firewall's PAN-OS version. Panorama templates may include features or syntax not supported by older firewall versions, causing the validation to fail. Therefore, verifying that the firewall's PAN-OS version is within the supported matrix for the Panorama version is the first logical step.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Ensure that the administrator account has superuser privileges.
Why it's wrong here
Administrator privileges affect what changes can be made, but template validation errors are not privilege-related.
- ✓
Verify that the firewall's PAN-OS version is supported by the Panorama version.
Why this is correct
Incompatible versions between Panorama and firewalls can cause template validation failures during push.
- ✗
Check that the firewall is connected to the internet for cloud services.
Why it's wrong here
Internet connectivity is not required for template validation; it is needed for cloud services but not for commit/push.
- ✗
Review the system logs on the firewall for disk space errors.
Why it's wrong here
Disk space errors would typically appear as commit failures, not template validation errors.
