PCNSE Manage, Monitor and Operate Practice Question
During a Panorama upgrade from version 9.0 to 9.1, the administrator notices that the commit fails on one of the managed firewalls with the error: 'Mismatched content version'. What is the most likely cause?
⚠ Common exam trap
It's easy for candidates to confuse 'content version mismatch' with 'PAN-OS version mismatch' or assume it is a licensing issue, but the error specifically points to the content database version incompatibility, not the base software version or license status.
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 firewall has an incompatible version of content updates installed.
The 'Mismatched content version' error occurs when the content (threat/application) version on the firewall is not compatible with the Panorama version being used. During a Panorama upgrade, the content version database format may change, and if the firewall has an older or incompatible content update installed, Panorama cannot validate the commit. This typically requires updating the firewall's content version to match the Panorama version's supported content database.
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 administrator forgot to push dynamic updates before the upgrade.
Why it's wrong here
Dynamic updates can be pushed after upgrade; the error specifically mentions content version mismatch.
- ✓
The firewall has an incompatible version of content updates installed.
Why this is correct
Panorama 9.1 requires a minimum content version on managed firewalls; if not met, commit fails.
- ✗
The firewall is not licensed for the new Panorama version.
Why it's wrong here
Licensing is not tied to content version mismatch errors.
- ✗
The firewall's software version is not compatible with Panorama 9.1.
Why it's wrong here
This would cause a different error, typically 'unsupported version'.
