PCNSE Core Concepts and Architecture Practice Question
Which THREE of the following are key differences between the Palo Alto Networks Next-Generation Firewall and Cloud-Delivered Security Services (CDSS)?
⚠ Common exam trap
The trap here is assuming CDSS replaces local firewall functions (like packet inspection or threat prevention) rather than understanding it as a complementary cloud service that enhances, not substitutes, the firewall's core enforcement capabilities.
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
✓
CDSS offers services like DNS Security and WildFire that require an internet connection to the cloud.
DNS Security and WildFire are cloud-delivered services that require an active internet connection to the Palo Alto Networks cloud for real-time analysis and signature retrieval. Unlike local threat prevention, these services offload processing to the cloud, enabling detection of unknown threats without consuming firewall resources.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
CDSS performs full application-level packet inspection.
Why it's wrong here
Packet inspection is done by the firewall, not CDSS.
- ✓
CDSS offers services like DNS Security and WildFire that require an internet connection to the cloud.
Why this is correct
These services rely on cloud connectivity.
- ✓
CDSS provides cloud-based threat analysis and signature updates, while the firewall is the enforcement point.
Why this is correct
CDSS offloads analysis to the cloud.
- ✗
CDSS is a replacement for the firewall's local threat prevention functionality.
Why it's wrong here
CDSS complements, not replaces, local capabilities.
- ✓
CDSS can automatically share threat intelligence across all subscribed firewalls.
Why this is correct
Threat intelligence is shared via cloud.
