Which two features of CN-Series firewalls protect east-west traffic between pods in different trust zones? (Choose two.)

Show Suggested Answer Hide Answer
Suggested Answer: A, D

The two features of CN-Series firewalls that protect east-west traffic between pods in different trust zones are:

Intrusion prevention system

Layer 7 visibility

East-west traffic is the traffic that flows between applications or workloads within a network or a cloud environment. Pods are the smallest units of deployment in Kubernetes, consisting of one or more containers that share resources and network space. Trust zones are segments of the network or the cloud environment that have different levels of security requirements or policies based on data sensitivity, user identity, device type, or application function. CN-Series firewalls are containerized firewalls that integrate with Kubernetes and provide visibility and control over container traffic. Intrusion prevention system is a feature of CN-Series firewalls that protects east-west traffic between pods in different trust zones by detecting and blocking known exploits and vulnerabilities using signature-based and behavior-based methods. Layer 7 visibility is a feature of CN-Series firewalls that protects east-west traffic between pods in different trust zones by identifying and classifying applications and protocols based on their content and characteristics, regardless of port, encryption, or evasion techniques. Communication with Panorama and external load balancer are not features of CN-Series firewalls that protect east-west traffic between pods in different trust zones, but they are related features that can enhance management and performance.

Definitely A and D! Those are key for east-west traffic.

I feel like external load balancer might not be relevant here, but I can't recall the exact details from my study sessions.

I’m a bit confused; I thought communication with Panorama was more about management than direct traffic protection.

I remember practicing a question about east-west traffic, and I think Layer 7 visibility was mentioned as a key feature.

I think the intrusion prevention system is definitely one of the features, but I'm not sure about the second one.

Ah, I remember this from the OSPF lessons. Manual route summarization is done on the ABRs, and by default, automatic summarization may or may not be optimal, depending on the network.

This seems straightforward. I'm pretty confident I know the right answer, but I'll double-check my work just to be sure.
