• Question 41:

  Which two methods of Zero Trust implementation can benefit an organization? (Choose two.)

  A. Compliance is validated.

  B. Boundaries are established.

  C. Security automation is seamlessly integrated.

  D. Access controls are enforced.

  Correct Answer: BD

  Explanation: The two methods of Zero Trust implementation that can benefit an organization are: Boundaries are established Access controls are enforced Zero Trust is a security model that assumes no trust for any entity or network segment, and requires continuous verification and validation of all connections and transactions. Zero Trust implementation can benefit an organization by improving its security posture, reducing its attack surface, and enhancing its visibility and compliance. Boundaries are established is a method of Zero Trust implementation that involves defining and segmenting the network into smaller zones based on data sensitivity, user identity, device type, or application function. Boundaries are established can benefit an organization by isolating and protecting critical assets from unauthorized access or lateral movement. Access controls are enforced is a method of Zero Trust implementation that involves applying granular security policies based on the principle of least privilege to each zone or connection. Access controls are enforced can benefit an organization by preventing data exfiltration, malware propagation, or credential theft. Compliance is validated and security automation is seamlessly integrated are not methods of Zero Trust implementation, but they may be potential outcomes or benefits of implementing Zero Trust.

• Question 42:

  How are CN-Series firewalls licensed?

  A. Data-plane vCPU

  B. Service-plane vCPU

  C. Management-plane vCPU

  D. Control-plane vCPU

  Correct Answer: A

  Explanation: 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 43:

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

  A. Positive K

  B. OpenShift

  C. OpenStack

  D. Native K8

  Correct Answer: BD

  Explanation: The two environments supported by the CN-Series firewall are: OpenShift Native K8 The CN-Series firewall is a containerized firewall that integrates with Kubernetes and provides visibility and control over container traffic. The CN-Series firewall can be deployed in various environments that support Kubernetes, such as public clouds, private clouds, or on-premises data centers. OpenShift is an environment supported by the CN-Series firewall. OpenShift is a platform that provides enterprise-grade Kubernetes and container orchestration, as well as developer tools and services. Native K8 is an environment supported by the CN-Series firewall. Native K8 is a term that refers to the standard Kubernetes distribution that is available from the Kubernetes project website, without any vendor-specific modifications or additions. Positive K and OpenStack are not environments supported by the CN-Series firewall, but they are related concepts that can be used for other purposes.

• Question 44:

  Auto scaling templates for which type of firewall 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?

  A. HA-Series

  B. CN-Series

  C. IPA-Series

  D. VM-Series

  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.

• Question 45:

  Which two actions can be performed for VM-Series firewall licensing by an orchestration system? (Choose two.)

  A. Creating a license

  B. Renewing a license

  C. Registering an authorization code

  D. Downloading a content update

  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.

• Question 46:

  Which two configuration options does Palo Alto Networks recommend for outbound high availability (HA) design in Amazon Web Services using a VM-Series firewall? (Choose two.)

  A. Transit VPC and Security VPC

  B. Traditional active-active HA

  C. Transit gateway and Security VPC

  D. Traditional active-passive HA

  Correct Answer: CD

  Explanation: Palo Alto Networks recommends two configuration options for outbound high availability (HA) design in Amazon Web Services using a VM-Series firewall: transit gateway and Security VPC, and traditional active-passive HA. Transit gateway and Security VPC allows you to use a single transit gateway to route traffic between multiple VPCs and the internet, while using a Security VPC to host the VM-Series firewalls. Traditional active-passive HA allows you to use two VM-Series firewalls in an HA pair, where one firewall is active and handles all traffic, while the other firewall is passive and takes over in case of a failure.

  Which three NSX features can be pushed from Panorama in PAN-OS? (Choose three.)

  A. Security group assignment of virtual machines (VMs)

  B. Security groups

  C. Steering rules

  D. User IP mappings

  E. Multiple authorization codes

  Correct Answer: ABC

• Question 48:

  Which two deployment modes of VM-Series firewalls are supported across NSX-T? (Choose two.)

  A. Prism Central

  B. Bootstrap

  C. Service Cluster

  D. Host-based

  Correct Answer: BC

  Explanation: The two deployment modes of VM-Series firewalls that are supported across NSX-T are: Bootstrap Service Cluster NSX-T is a software-defined network (SDN) solution that provides network virtualization, automation, and security for cloud-native applications. Bootstrap is a method of deploying and configuring VM-Series firewalls in NSX-T using a bootstrap package that contains the initial setup information, such as licenses, certificates, software updates, and configuration files. Service Cluster is a mode of deploying VM-Series firewalls in NSX-T as a group of firewalls that act as a single logical firewall to provide scalability and high availability. Prism Central, Host-based, and Service Insertion are not deployment modes of VM-Series firewalls in NSX-T, but they are related concepts that can be used for other purposes.

• Question 49:

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

  A. Special AWS plugins are needed for load balancing.

  B. Resources are shared within the cluster.

  C. Only active-passive high availability (HA) is supported.

  D. High availability (HA) clusters are limited to fewer than 8 virtual appliances.

  Correct Answer: C

  Explanation: 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 50:

  Which type of group allows sharing cloud-learned tags with on-premises firewalls?

  A. Device

  B. Notify

  C. Address

  D. Template

  Correct Answer: C

  Explanation: Address groups are the type of groups that allow sharing cloud-learned tags with on-premises firewalls. Address groups are dynamic objects that can include IP addresses or tags as members. Cloud-learned tags are tags that are assigned to cloud resources by cloud providers or third-party tools. By using address groups with cloud- learned tags, you can apply consistent security policies across your hybrid cloud environment. References: [Address Groups]
