Palo Alto Networks PCSFE Exam - Topic 4 Question 46 Discussion

Actual exam question for Palo Alto Networks's PCSFE exam
Question #: 46
Topic #: 4
[All PCSFE Questions]

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

Show Suggested Answer Hide Answer
Suggested Answer: C

Containers are the elements that a CN-Series firewall can secure traffic between. Containers are isolated units of software that run on a shared operating system and have their own resources, dependencies, and configuration. A CN-Series firewall can inspect and enforce security policies on traffic between containers within a pod, across pods, or across namespaces in a Kubernetes cluster. Host containers, source applications, and IPods are not valid elements that a CN-Series firewall can secure traffic between.

Wait, can it really secure IPods? That sounds off.

I don't think IPods are relevant here; they seem more like a distraction in the options.

I feel like the focus was on containers, but I might be mixing it up with another type of firewall.

I remember practicing a question about firewalls and applications, but I can't recall if source applications were specifically mentioned for CN-Series.

I think the CN-Series firewall secures traffic between containers, but I'm not entirely sure if it includes host containers too.

Okay, I've got a strategy. I'll start by ruling out the options that don't make sense, then focus on the ones that seem more plausible based on my understanding of firewalls.

I'm a bit confused by the options. IPods? That doesn't seem relevant at all. I'll have to eliminate the clearly wrong answers first.

Host containers seems like the most logical option here. Firewalls are often used to secure traffic between different containers or virtual environments.

Hmm, this is a tricky one. I'm not super familiar with CN-Series firewalls, so I'll have to think this through carefully.

I'm pretty sure this is asking about the capabilities of a CN-Series firewall, so I'll focus on the options that mention securing traffic between different elements.
