質問 # 23
Which Palo Alto Networks firewall provides network security when deploying a microservices-based application?
- A. PA-Series
- B. HA-Series
- C. VM-Series
- D. ICN-Series
正解：D
解説：
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.

質問 # 24
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. Traditional active-passive HA
- B. Traditional active-active HA
- C. Transit VPC and Security VPC
- D. Transit gateway and Security VPC
正解：A、D
解説：
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. Reference: [VM-Series Deployment Guide for AWS Outbound VPC]
質問 # 25
When implementing active-active high availability (HA), which feature must be configured to allow the HA pair to share a single IP address that may be used as the network's gateway IP address?
- A. VRRP
- B. ARP load sharing
- C. Floating IP address
- D. HSRP
正解：C
質問 # 26
What is the structure of the YAML Ain't Markup Language (YAML) file repository?
- A. Kubernetes/Deployment Type/Environment
- B. Kubernetes/Environment/Deplovment Type
- C. Deployment Type/Kubernetes/Environment
- D. Environment/Kubernetes/Deployment Type
正解：A
解説：
Kubernetes/Deployment Type/Environment is the structure of the YAML Ain't Markup Language (YAML) file repository. YAML is a human-readable data serialization language that is commonly used for configuration files. YAML file repository is a collection of YAML files that specify the resources and configuration for deploying and managing infrastructure components, such as firewalls, load balancers, networks, or servers. Kubernetes/Deployment Type/Environment is the structure of the YAML file repository that organizes the YAML files based on the following criteria:
Kubernetes: The platform that provides orchestration, automation, and management of containerized applications.
Deployment Type: The method or model of deploying and managing infrastructure components, such as Terraform, Ansible, Helm, or Kubernetes manifests.
Environment: The type or stage of the cloud or virtualization environment, such as development, testing, staging, or production. Deployment Type/Kubernetes/Environment, Kubernetes/Environment/Deployment Type, and Environment/Kubernetes/Deployment Type are not the structure of the YAML file repository, but they are related ways of organizing YAML files based on different criteria. Reference: [Palo Alto Networks Certified Software Firewall Engineer (PCSFE)], [What is YAML?], [YAML File Repository]
質問 # 27
What helps avoid split brain in active-passive high availability (HA) pair deployment?
- A. Enabling preemption on both firewalls in the HA pair
- B. Using the management interface as the HA1 backup link
- C. Using a standard traffic interface as the HA3 link
- D. Using a standard traffic interface as the HA2 backup
正解：B
解説：
Using the management interface as the HA1 backup link helps avoid split brain in active-passive high availability (HA) pair deployment. 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. Split brain is a condition that occurs when both firewalls in an HA pair assume the active role and start processing traffic independently, resulting in traffic duplication, policy inconsistency, or session disruption. Split brain can be caused by network failures, device failures, or configuration errors that prevent the firewalls from communicating their HA status and synchronizing their configurations and sessions. Using the management interface as the HA1 backup link helps avoid split brain in active-passive HA pair deployment. The HA1 interface is used for exchanging HA state information and configuration synchronization between the firewalls. Using the management interface as the HA1 backup link provides redundancy and failover protection for the HA1 interface, ensuring that the firewalls can maintain their HA communication and avoid split brain. Using a standard traffic interface as the HA2 backup, enabling preemption on both firewalls in the HA pair, or using a standard traffic interface as the HA3 link do not help avoid split brain in active-passive HA pair deployment, but they are related features that can enhance performance and reliability.

質問 # 28
What are two requirements for automating service deployment of a VM-Series firewall from an NSX Manager? (Choose two.)
- A. vCenter has been given Palo Alto Networks subscription licenses for VM-Series firewalls.
- B. Panorama has been configured to recognize both the NSX Manager and vCenter.
- C. Panorama can establish communications to the public Palo Alto Networks update servers.
- D. The deployed VM-Series firewall can establish communications with Panorama.
正解：B、D
解説：
The two requirements for automating service deployment of a VM-Series firewall from an NSX Manager are:
Panorama has been configured to recognize both the NSX Manager and vCenter.
The deployed VM-Series firewall can establish communications with Panorama.
NSX Manager is a software component that provides centralized management and control of the NSX environment, including network virtualization, automation, and security. Service deployment is a process that involves deploying and configuring network services, such as firewalls, load balancers, or routers, on the NSX environment. VM-Series firewall is a virtualized version of the Palo Alto Networks next-generation firewall that can be deployed on various cloud or virtualization platforms, including NSX. Panorama is a centralized management server that provides visibility and control over multiple Palo Alto Networks firewalls and devices. Panorama has been configured to recognize both the NSX Manager and vCenter is a requirement for automating service deployment of a VM-Series firewall from an NSX Manager. vCenter is a software component that provides centralized management and control of the VMware environment, including hypervisors, virtual machines, and other resources. Panorama has been configured to recognize both the NSX Manager and vCenter by adding them as VMware service managers and enabling service insertion for VM-Series firewalls on NSX. This allows Panorama to communicate with the NSX Manager and vCenter, retrieve information about the NSX environment, and deploy and manage VM-Series firewalls as network services on the NSX environment. The deployed VM-Series firewall can establish communications with Panorama is a requirement for automating service deployment of a VM-Series firewall from an NSX Manager. The deployed VM-Series firewall can establish communications with Panorama by registering with Panorama using its serial number or IP address, and receiving configuration updates and policy rules from Panorama. This allows the VM-Series firewall to operate as part of the Panorama management domain, synchronize its settings and status with Panorama, and report its logs and statistics to Panorama. vCenter has been given Palo Alto Networks subscription licenses for VM-Series firewalls and Panorama can establish communications to the public Palo Alto Networks update servers are not requirements for automating service deployment of a VM-Series firewall from an NSX Manager, as those are not related or relevant factors for service deployment automation.

質問 # 29
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?
- A. Create a new virtual switch and use the VM-Series firewall to separate virtual switches using virtual wire mode. Then move the guests that require more security into the new virtual switch.
- B. Send the VLAN out of the virtual environment into a hardware Palo Alto Networks firewall in Layer 3 mode. Use the same IP address as the old default gateway, then delete it.
- C. Create a Layer 3 interface in the same subnet as the VMs and then configure proxy Address Resolution Protocol (ARP).
- D. Edit the IP address of all of the affected VMs. www*
正解：A
解説：
The partition can be accomplished without editing the IP addresses or the default gateways of any of the guest VMs by creating a new virtual switch and using the VM-Series firewall to separate virtual switches using virtual wire mode. Then move the guests that require more security into the new virtual switch. A virtual switch is a software-based switch that connects virtual machines (VMs) in a VMware ESXi environment. A virtual wire is a deployment mode of the VM-Series firewall that allows it to act as a bump in the wire between two network segments, without requiring an IP address or routing configuration. By creating a new virtual switch and using the VM-Series firewall to separate virtual switches using virtual wire mode, the customer can isolate the group of VMs that require more security from the rest of the network, and apply security policies to the traffic passing through the firewall. The partition cannot be accomplished without editing the IP addresses or the default gateways of any of the guest VMs by editing the IP address of all of the affected VMs, creating a Layer 3 interface in the same subnet as the VMs and then configuring proxy Address Resolution Protocol (ARP), or sending the VLAN out of the virtual environment into a hardware Palo Alto Networks firewall in Layer 3 mode. Use the same IP address as the old default gateway, then delete it, as those methods would require changing the network configuration of the guest VMs or introducing additional complexity and latency.

質問 # 31
What does the number of required flex credits for a VM-Series firewall depend on?
- A. IP address allocation
- B. Network interface allocation
- C. vCPU allocation
- D. Memory allocation
正解：C
解説：
The number of required flex credits for a VM-Series firewall depends on vCPU allocation. Flex 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 flex credits to provision VM-Series firewalls on any supported cloud or virtualization platform. The number of required flex credits for a VM-Series firewall depends on vCPU allocation, which is the number of virtual CPUs assigned to the VM-Series firewall instance. The vCPU allocation determines the performance and capacity of the VM-Series firewall instance, such as throughput, sessions, policies, rules, and features. The number of required flex credits for a VM-Series firewall does not depend on IP address allocation, network interface allocation, or memory allocation, as those are not factors that affect the licensing cost or consumption of flex credits. Reference: Palo Alto Networks Certified Software Firewall Engineer (PCSFE), [Flex Credits Datasheet], [Flex Credits FAQ], [VM-Series System Requirements]

- A. Security automation is seamlessly integrated.
- B. Compliance is validated.
- C. Boundaries are established.
- D. Access controls are enforced.
正解：C、D
解説：
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.

質問 # 36
Which two mechanisms could trigger a high availability (HA) failover event? (Choose two.)
- A. Ping monitoring
- B. Heartbeat polling
- C. Session polling
- D. Link monitoring
正解：B、D
解説：
Heartbeat polling and link monitoring are two mechanisms that can trigger an HA failover event. Heartbeat polling is a method of verifying the health of the peer firewall by sending periodic heartbeat messages. If the heartbeat messages are not received within a specified interval, the firewall assumes that the peer is down and initiates a failover. Link monitoring is a method of verifying the connectivity of the interfaces on the firewall by sending link state packets. If the link state packets are not received on a specified number of interfaces, the firewall assumes that the network is down and initiates a failover. Ping monitoring and session polling are not HA mechanisms, but they are used for path monitoring and session synchronization respectively.
