NetSec-Architect Practice Question: NGFW And Cloud Delivered Security Services Architecture
An enterprise network security architect is integrating Cortex XSIAM and Cortex XDR threat intelligence feeds with physical Palo Alto Networks NGFWs using PAN-OS services. Which THREE mechanisms are used to distribute and apply this integrated threat intelligence across the architecture? (Choose three)
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
✓
Log forwarding and automated response actions via Panorama and Cortex integrations
Threat intelligence and indicators are distributed across PAN-OS architectures using External Dynamic Lists (EDLs), automated policy enforcement via Cortex XSOAR/XSIAM integrations, and direct automated threat feed synchronization to the firewalls.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Log forwarding and automated response actions via Panorama and Cortex integrations
Why this is correct
Panorama and Cortex integrations can automate security policy and object updates based on threat findings.
- ✗
Direct SNMPv2 trap broadcasting from XSIAM to individual firewall data planes
Why it's wrong here
SNMPv2 is an old monitoring protocol, not the mechanism used for distributing dynamic threat intelligence feeds.
- ✓
PAN-OS integrated threat feeds and Automated Indicator Sharing (AIS)
Why this is correct
PAN-OS natively consumes automated threat feeds and standards such as TAXII/AIS.
- ✗
Manual USB firmware flashing of indicator database updates on every firewall
Why it's wrong here
Threat intelligence updates are automated continuously through cloud services, never via manual USB flashing.
- ✓
External Dynamic Lists (EDLs) updated dynamically via cloud feeds
Why this is correct
EDLs allow firewalls to pull updated threat indicators dynamically from external URLs and feeds.
