PCNSA Managing Objects Practice Question
A company needs to block a list of known malicious domains that is updated daily by a threat intelligence vendor. Which Palo Alto Networks object should be used?
⚠ Common exam trap
It's easy for candidates to confuse Custom URL Categories with EDLs, assuming a manually updated list can suffice for dynamic feeds, but the exam emphasizes that EDLs are the only object designed for automated, external-sourced updates.

Correct answer & explanation
✓
External Dynamic List (EDL)
An External Dynamic List (EDL) is the correct object because it allows Palo Alto Networks firewalls to import and automatically update a list of known malicious domains from an external threat intelligence vendor on a scheduled basis (e.g., every 5 minutes). This ensures the firewall dynamically blocks newly identified malicious domains without manual intervention, making it ideal for a daily-updated feed.
