What is the appropriate file format for Kubernetes applications?
In Kubernetes, configuration files are typically written in YAML (.yaml) format. YAML (Yet Another Markup Language) is preferred due to its readability and ease of use for defining complex data structures like those required for Kubernetes deployments. Kubernetes uses these YAML files to define resources such as pods, services, and deployments.

Which two criteria are required to deploy VM-Series firewalls in high availability (HA)? (Choose two.)
For deploying VM-Series firewalls in high availability (HA), it is crucial to ensure that both firewalls in the HA pair have identical licenses and subscriptions to ensure feature parity and uninterrupted service during failover. Additionally, both firewalls must be deployed on the same type of hypervisor to ensure compatibility and proper synchronization of state and configurations between the active and passive units.

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

How are CN-Series firewalls licensed?
Data-plane vCPU Licensing:
The CN-Series firewalls are licensed based on the number of data-plane vCPUs. This licensing model reflects the processing power dedicated to handling traffic and security enforcement within the containerized environment.
