A CN-Series firewall can secure traffic between which elements?
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. Reference:Palo Alto Networks Certified Software Firewall Engineer (PCSFE), [CN-Series Concepts], [What is a Container?]
Where do CN-Series devices obtain a VM-Series authorization key?
CN-Series devices obtain a VM-Series authorization key from Panorama. Panorama is a centralized management server that provides visibility and control over multiple Palo Alto Networks firewalls and devices. A VM-Series authorization key is a license key that activates the VM-Series firewall features and capacities. CN-Series devices obtain a VM-Series authorization key from Panorama by registering with Panorama using their CPU ID and requesting an authorization code from Panorama's license pool. Panorama then generates an authorization key for the CN-Series device and sends it back to the device for activation. CN-Series devices do not obtain a VM-Series authorization key from local installation, GitHub, or Customer Support Portal, as those are not valid or relevant sources for license management.

Which PAN-OS feature allows for automated updates to address objects when VM-Series firewalls are setup as part of an NSX deployment?
Dynamic Address Group is the PAN-OS feature that allows for automated updates to address objects when VM-Series firewalls are setup as part of an NSX deployment. NSX is a software-defined network (SDN) solution that provides network virtualization, automation, and security for cloud-native applications. Dynamic Address Group is an object that represents a group of IP addresses based on criteria such as tags, regions, interfaces, or user-defined attributes. Dynamic Address Group allows Security policies to adapt dynamically to changes in the network topology or workload characteristics without requiring manual updates. When VM-Series firewalls are setup as part of an NSX deployment, they can leverage the NSX tags assigned to virtual machines (VMs) or containers by the NSX manager or controller to populate Dynamic Address Groups and update Security policies accordingly. Boundary automation, Hypervisor integration, and Bootstrapping are not PAN-OS features that allow for automated updates to address objects when VM-Series firewalls are setup as part of an NSX deployment, but they are related concepts that can be used for other purposes. Reference:Palo Alto Networks Certified Software Firewall Engineer (PCSFE), [Dynamic Address Groups Overview], [Deploy the VM-Series Firewall on VMware NSX]
A customer in a VMware ESXi environment wants to add a VM-Series firewall and partition an existing group of virtual machines (VMs) in the same subnet into two groups. One group requires no additional security, but the second group requires substantially more security.
How can this partition be accomplished without editing the IP addresses or the default gateways of any of the guest VMs?
Which component can provide application-based segmentation and prevent lateral threat movement?
