[All PSE-SoftwareFirewall Questions]

A CN-Series firewall can secure traffic between which elements?

Show Suggested Answer Hide Answer
Suggested Answer: C

The CN-Series firewalls are specifically designed to secure containerized environments. They can secure traffic between Kubernetes pods, which are the smallest deployable units in a Kubernetes cluster, and are often composed of one or more containers. The primary focus of CN-Series firewalls is to ensure security within Kubernetes environments by managing traffic and enforcing security policies at the pod level.

D) Source applications seems like the obvious choice here. The firewall is there to secure the traffic, not just the containers themselves.

If I recall correctly, the CN-Series firewall is designed to secure traffic between containers and pods, but I might need to double-check that.

I'm a little confused by the options here. Are host containers, pods, and source applications all different types of network elements? I'll need to double-check my understanding before answering this one.

I think this question is asking about the capabilities of the CN-Series firewall. I'll need to review my notes on that firewall model to determine which network elements it can secure traffic between.
