PCNSA Securing Traffic Practice Question
An organization wants to segment internal traffic between the Engineering and Finance departments and apply threat prevention. Which TWO actions should be taken? (Choose two.)
⚠ Common exam trap
A common mix-up: candidates confuse NAT or QoS with security controls, thinking address translation or bandwidth management can segment traffic, when in fact only zones and security rules enforce access control and threat inspection.
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
✓
Define separate security zones for Engineering and Finance.
Security zones are the fundamental building blocks for segmenting traffic in Palo Alto Networks firewalls. By placing Engineering and Finance interfaces into separate zones, you create a trust boundary that allows you to enforce inter-zone security rules. Option E is correct because applying Threat Prevention profiles (e.g., antivirus, anti-spyware, vulnerability protection) to the inter-zone rule enables the firewall to inspect and block malicious traffic between the segmented departments.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure NAT policies to translate internal addresses.
Why it's wrong here
NAT handles address translation, not traffic segmentation or threat prevention.
- ✓
Define separate security zones for Engineering and Finance.
Why this is correct
Separate zones allow fine-grained security policies between departments.
- ✗
Create a single security zone for all internal traffic.
Why it's wrong here
A single zone does not provide segmentation; all devices would be in the same trust level.
- ✗
Enable QoS policies between the zones.
Why it's wrong here
QoS manages bandwidth, not security access control.
- ✓
Apply Threat Prevention profiles to the inter-zone security rules.
Why this is correct
Threat Prevention profiles inspect traffic for malware and exploits, essential for inter-zone security.
