Why are VM-Series firewalls and hardware firewalls that are external to the Kubernetes cluster problematic for protecting containerized workloads?

  1. They function differently based on whether they are located inside or outside of the cluster.
  2. They are located outside the cluster and have no visibility into application-level cluster traffic.
  3. They are managed by another entity when located inside the cluster.
  4. They do not scale independently of the Kubernetes cluster.

Answer(s): B

Explanation:

Visibility into application-level cluster traffic:
VM-Series firewalls and hardware firewalls that are external to the Kubernetes cluster lack the necessary visibility into the traffic and communications occurring at the application level within the cluster. This limitation impedes their ability to effectively protect containerized workloads.


Reference:

Palo Alto Networks documentation highlights the challenges of external firewalls in securing Kubernetes environments due to limited visibility into internal traffic.

What are two environments supported by the CN-Series firewall? (Choose two.)

  1. OpenShift
  2. Positive K
  3. Native K8
  4. OpenStack

Answer(s): A,C

Explanation:

OpenShift:
The CN-Series firewall supports deployment in Red Hat OpenShift environments. OpenShift is a Kubernetes-based container platform that provides a comprehensive solution for container orchestration.


Reference:

Palo Alto Networks documentation on CN-Series firewalls mentions support for OpenShift.
Palo Alto Networks CN-Series Deployment Guide

Native K8:
The CN-Series firewall is designed to be deployed in native Kubernetes (K8s) environments, providing security for containerized applications running within the Kubernetes clusters.

The CN-Series deployment documentation specifies support for native Kubernetes environments.

Which software firewall would assist a prospect who is interested in securing extensive DevOps deployments?

  1. VM-Series
  2. CN-Series
  3. Ion-Series
  4. Cloud next-generation firewall (NGFW)

Answer(s): B

Explanation:

CN-Series for DevOps deployments:
The CN-Series firewall is specifically designed to secure containerized environments and is ideal for protecting extensive DevOps deployments. It integrates seamlessly with Kubernetes and other container orchestration platforms, providing the necessary security controls for DevOps processes.


Reference:

Palo Alto Networks highlights the CN-Series as the solution for securing containerized workloads, which are a core component of many DevOps environments.

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

  1. Intrusion prevention system (IPS)
  2. Communication with Panorama
  3. External load balancer (ELB)
  4. Layer 7 visibility

Answer(s): A,D

Explanation:

Intrusion Prevention System (IPS): The CN-Series firewalls incorporate an Intrusion Prevention System to detect and prevent exploits and attacks on applications and systems. This feature is essential for securing east-west traffic, as it can identify and block threats within the data center traffic between pods in different trust zones.
Layer 7 Visibility: CN-Series firewalls provide Layer 7 (application layer) visibility, enabling deep inspection of application traffic. This allows the firewall to understand and enforce policies based on the application and its behavior, rather than just ports and protocols, ensuring comprehensive security for east-west traffic within a Kubernetes environment.
