NetSec-Architect Zero Trust Architecture And Design Practice Question
An enterprise architect is designing a Zero Trust architecture for Kubernetes container environments using Palo Alto Networks CN-Series container native firewalls. Where must the CN-Series firewall be positioned to inspect pod-to-pod traffic within a Kubernetes cluster effectively?
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
✓
Inline within the Kubernetes cluster network path as containerized instances (CN-Series) inspecting pod-to-pod traffic via Kubernetes service insertion and CNI integration
CN-Series firewalls are deployed as daemonsets or containerized firewalls enforcing micro-segmentation at the Kubernetes CNI (Container Network Interface) layer for pod-to-pod east-west traffic inspection.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Installed directly on employee laptops as a browser extension
Why it's wrong here
Incorrect. Browser extensions cannot inspect Kubernetes container cluster traffic.
- ✓
Inline within the Kubernetes cluster network path as containerized instances (CN-Series) inspecting pod-to-pod traffic via Kubernetes service insertion and CNI integration
Why this is correct
Correct. CN-Series provides container-native inspection for east-west pod traffic.
- ✗
As a physical hardware appliance sitting outside the Kubernetes worker node cluster racks
Why it's wrong here
Incorrect. Intra-cluster pod-to-pod traffic does not traverse physical cluster rack switches, bypassing external physical firewalls.
- ✗
Configured exclusively as an SMTP mail relay proxy in the DMZ
Why it's wrong here
Incorrect. This is unrelated to Kubernetes cluster pod inspection.
