Correct Answer: A

Explanation: 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.

Correct Answer: A

Explanation: VM-Series firewalls and hardware firewalls that are external to the Kubernetes cluster are problematic for protecting containerized workloads because they are located outside the cluster and have no visibility into application-level cluster traffic. Kubernetes is a platform that provides orchestration, automation, and management of containerized applications. Kubernetes cluster traffic consists of traffic between containers within a pod, across pods, or across namespaces. VM-Series firewalls and hardware firewalls that are external to the Kubernetes cluster cannot inspect or control this traffic, as they only see the encapsulated or aggregated traffic at the network layer. This creates blind spots and security gaps for containerized workloads. VM-Series firewalls and hardware firewalls that are external to the Kubernetes cluster are not problematic for protecting containerized workloads because they do not scale independently of the Kubernetes cluster, are managed by another entity when located inside the cluster, or function differently based on whether they are located inside or outside of the cluster, as those are not valid reasons or scenarios for firewall deployment in a Kubernetes environment.

Correct Answer: B

Explanation: A Palo Alto Networks Next-Generation Firewall (NGFW) must be configured to use a Layer 3 underlay network in order to secure traffic in a Cisco ACI environment. A Layer 3 underlay network is a physical network that provides IP connectivity between devices, such as routers, switches, and firewalls. A Palo Alto Networks NGFW must use a Layer 3 underlay network to communicate with the Cisco ACI fabric and receive traffic redirection from the Cisco ACI policy-based redirect mechanism. A Palo Alto Networks NGFW does not need to be deployed as a member of a device cluster, receive all forwarding lookups from the network controller, or be identified as a default gateway in order to secure traffic in a Cisco ACI environment, as those are not valid requirements or options for firewall integration with Cisco ACI.

Correct Answer: D

Explanation: CN-Series firewall is the software firewall that would help a prospect interested in securing an environment with Kubernetes. Kubernetes is a platform that provides orchestration, automation, and management of containerized applications. Kubernetes environment requires network security that can protect the inter-service communication from cyberattacks and enforce granular security policies based on application or workload characteristics. CN-Series firewall is a containerized firewall that integrates with Kubernetes and provides visibility and control over container traffic. CN- Series firewall can help a prospect interested in securing an environment with Kubernetes by inspecting and enforcing security policies on traffic between containers within a pod, across pods, or across namespaces in a Kubernetes cluster. KN-Series, ML-Series, VM- Series, and Cloud next-generation firewall are not software firewalls that would help a prospect interested in securing an environment with Kubernetes, but they are related solutions that can be deployed on different platforms or environments.

Correct Answer: D

Explanation: CN-Series firewall prevents exfiltration by inspecting outbound traffic content and blocking suspicious activity. Exfiltration is a technique used by attackers to steal sensitive data or assets from a compromised network or system, usually by sending them to an external destination, such as a command and control server, a drop zone, or an email address. CN-Series firewall is a containerized firewall that integrates with Kubernetes and provides visibility and control over container traffic. CN-Series firewall prevents exfiltration by inspecting outbound traffic content and blocking suspicious activity using threat prevention technologies, such as antivirus, anti-spyware, vulnerability protection, URL filtering, file blocking, data filtering, and WildFire analysis. CN-Series firewall does not prevent exfiltration by employing custom-built signatures based on hash, distributing incoming virtual private cloud (VPC) traffic across the pool of VM-Series firewalls, or providing a license deactivation API key, as those are not valid or relevant methods for exfiltration prevention.

Correct Answer: D

Explanation: Auto scaling templates for VM-Series firewalls enable deployment of a single auto scaling group (ASG) of VM-Series firewalls to secure inbound traffic from the internet to Amazon Web Services (AWS) application workloads. An ASG is a collection of EC2 instances that share similar characteristics and can be scaled up or down automatically based on demand or predefined conditions. Auto scaling templates for VM-Series firewalls are preconfigured templates that provide the necessary resources and configuration to deploy and manage VM-Series firewalls in an ASG on AWS. Auto scaling templates for VM-Series firewalls can be used to secure inbound traffic from the internet to AWS application workloads by placing the ASG of VM-Series firewalls behind an AWS Application Load Balancer (ALB) or a Gateway Load Balancer (GWLB) that distributes the traffic across the firewalls. The firewalls can then inspect and enforce security policies on the inbound traffic before sending it to the application workloads. Auto scaling templates for HA-Series, CN-Series, and IPA-Series firewalls do not enable deployment of a single ASG of VM-Series firewalls to secure inbound traffic from the internet to AWS application workloads, as those are different types of firewalls that have different deployment models and use cases.

Correct Answer: AC

Explanation: The two actions that can be performed for VM-Series firewall licensing by an orchestration system are: Creating a license Registering an authorization code An orchestration system is a software tool that automates and coordinates complex tasks across multiple devices or platforms. An orchestration system can perform various actions for VM-Series firewall licensing by using the Palo Alto Networks Licensing API. The Licensing API is a RESTful API that allows programmatic control of license management for VM-Series firewalls. Creating a license is an action that can be performed for VM-Series firewall licensing by an orchestration system using the Licensing API. Creating a license involves generating a license key for a VM-Series firewall based on its CPU ID and the license type. Registering an authorization code is an action that can be performed for VM- Series firewall licensing by an orchestration system using the Licensing API. Registering an authorization code involves activating a license entitlement for a VM-Series firewall based on its authorization code and CPU ID. Renewing a license and downloading a content update are not actions that can be performed for VM-Series firewall licensing by an orchestration system using the Licensing API, but they are related tasks that can be done manually or through other methods.

Correct Answer: BC

Explanation: The two statements that apply to the VM-Series plugin are:

It can be upgraded independently of PAN-OS.

It enables management of cloud-specific interactions between VM-Series firewalls and supported public cloud platforms.

The VM-Series plugin is a software component that extends the functionality of the PAN- OS operating system to support cloud-specific features and APIs. The VM-Series plugin can be upgraded independently of PAN-OS to provide faster

access to new cloud capabilities and integrations. The VM-Series plugin enables management of cloud-specific interactions between VM-Series firewalls and supported public cloud platforms, such as AWS, Azure, GCP, Alibaba Cloud, and

Oracle Cloud. These interactions include bootstrapping, licensing, scaling, high availability, load balancing, and tagging. The VM- Series plugin cannot manage capabilities common to both VM-Series firewalls and hardware firewalls, as those

are handled by PAN-OS. The VM-Series plugin cannot manage Panorama plugins, as those are separate software components that extend the functionality of the Panorama management server to support cloud-specific features and APIs.

Correct Answer: B

Explanation: Tags allow a VM-Series firewall to adapt Security policy rules dynamically in a virtual environment. Tags are labels or identifiers that can be assigned to virtual machines (VMs), containers, or other resources in a virtual environment. Tags can be used to group resources based on various criteria, such as application, function, location, owner, or security posture. A VM-Series firewall can leverage tags to populate Dynamic Address Groups and update Security policies accordingly, without requiring manual changes. Tags do not enable machine learning (ML), integrate with security information and event management (SIEM) solutions, or provide adaptive reporting, but they are related features that can enhance security and visibility.
