PCNSA Managing Objects Practice Question
An administrator has created an address group that includes an FQDN address object. When the FQDN's IP address changes, how does the firewall update the group?
⚠ Common exam trap
Test-takers frequently think FQDNs require manual updates or that only dynamic groups support automatic resolution, but Palo Alto firewalls resolve FQDNs at commit for any group type.

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 automatically resolves the FQDN at commit and updates the group accordingly.
Palo Alto Networks firewalls automatically resolve FQDNs at commit time. When an FQDN address object is included in an address group, the firewall performs a DNS resolution during the commit process and updates the group with the current IP address(es). This ensures that the group reflects the latest IP mapping without requiring manual intervention.
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 must manually update the address object's IP address.
Why it's wrong here
Manual update is not required; the firewall handles resolution.
- ✗
Only if the address group is dynamic will the update occur automatically.
Why it's wrong here
Dynamic groups are based on tags, not FQDN resolution. FQDN resolution happens regardless.
- ✗
FQDN objects cannot be included in address groups.
Why it's wrong here
FQDN objects are allowed in static address groups.
- ✓
The firewall automatically resolves the FQDN at commit and updates the group accordingly.
Why this is correct
FQDN resolution occurs at commit, ensuring the group uses the current IP.
