Question No. 1

What can software next-generation firewall (NGFW) credits be used to provision?

Show Answer Hide Answer
Correct Answer: C

Software next-generation firewall (NGFW) credits can be used to provision migrating NGFWs from hardware to VMs. Software NGFW credits are a flexible licensing model that allows customers to purchase and consume software NGFWs as needed, without having to specify the platform or deployment model upfront. Customers can use software NGFW credits to migrate their existing hardware NGFWs to VM-Series firewalls on any supported cloud or virtualization platform, or to deploy new VM-Series firewalls as their needs grow. Software NGFW credits cannot be used to provision remote browser isolation, virtual Panorama appliances, or enablement of DNS security, as those are separate solutions that require different licenses or subscriptions.

Question No. 2

What is a design consideration for a prospect who wants to deploy VM-Series firewalls in an Amazon Web Services (AWS) environment?

Show Answer Hide Answer
Correct Answer: C

A design consideration for a prospect who wants to deploy VM-Series firewalls in an Amazon Web Services (AWS) environment is that only active-passive high availability (HA) is supported. High availability (HA) is a feature that provides redundancy and failover protection for firewalls in case of hardware or software failure. Active-passive HA is a mode of HA that consists of two firewalls in a pair, where one firewall is active and handles all traffic, while the other firewall is passive and acts as a backup. Active-passive HA is the only mode of HA that is supported for VM-Series firewalls in an AWS environment, due to the limitations of AWS networking and routing. Active-active HA, which is another mode of HA that consists of two firewalls in a pair that both handle traffic and synchronize sessions, is not supported for VM-Series firewalls in an AWS environment. A design consideration for a prospect who wants to deploy VM-Series firewalls in an AWS environment is not that special AWS plugins are needed for load balancing, resources are shared within the cluster, or high availability (HA) clusters are limited to fewer than 8 virtual appliances, as those are not valid or relevant factors for firewall deployment in an AWS environment.

Question No. 3

How are CN-Series firewalls licensed?

Show Answer Hide Answer
Correct Answer: A

CN-Series firewalls are licensed by data-plane vCPU. Data-plane vCPU is the number of virtual CPUs assigned to the data plane of the CN-Series firewall instance. The data plane is the part of the CN-Series firewall that processes network traffic and applies security policies. CN-Series firewalls are licensed by data-plane vCPU, which determines the performance and capacity of the CN-Series firewall instance, such as throughput, sessions, policies, rules, and features. CN-Series firewalls are not licensed by service-plane vCPU, management-plane vCPU, or control-plane vCPU, as those are not factors that affect the licensing cost or consumption of CN-Series firewalls.

Question No. 4

Which Palo Alto Networks firewall provides network security when deploying a microservices-based application?

Show Answer Hide Answer
Correct Answer: B

CN-Series firewall is the Palo Alto Networks firewall that provides network security when deploying a microservices-based application. A microservices-based application is an application that consists of multiple independent and loosely coupled services that communicate with each other through APIs. A microservices-based application 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 provide network security when deploying a microservices-based application by inspecting and enforcing security policies on traffic between containers within a pod, across pods, or across namespaces in a Kubernetes cluster. PA-Series, VM-Series, and HA-Series are not Palo Alto Networks firewalls that provide network security when deploying a microservices-based application, but they are related solutions that can be deployed on different platforms or environments.

Question No. 5

Which component allows the flexibility to add network resources but does not require making changes to existing policies and rules?

Show Answer Hide Answer
Correct Answer: D

Dynamic address group is the component that allows the flexibility to add network resources but does not require making changes to existing policies and rules. 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. Content-ID, External dynamic list, and App-ID are not components that allow the flexibility to add network resources but do not require making changes to existing policies and rules, but they are related features that can enhance security and visibility.
