Palo Alto Networks PCSFE Palo Alto Networks Certified Software Firewall Engineer Exam Practice Test

Answer : A, C

The two routing options that are supported by VM-Series are:

OSPF

BGP

Routing is a process that determines the best path for sending network packets from a source to a destination. Routing options are protocols or methods that enable routing between different networks or devices. 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. VM-Series firewall supports various routing options that allow it to participate in dynamic routing environments and exchange routing information with other routers or devices. OSPF and BGP are two routing options that are supported by VM-Series. OSPF is a routing option that uses link-state routing algorithm to determine the shortest path between routers within an autonomous system (AS). BGP is a routing option that uses path vector routing algorithm to determine the best path between routers across different autonomous systems (ASes). RIP and IGRP are not routing options that are supported by VM-Series, but they are related protocols that can be used for other purposes.

Answer : B

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.

Answer : B

Cloud next-generation firewall is the Palo Alto Networks software firewall that protects Amazon Web Services (AWS) deployments with network security delivered as a managed cloud service. Cloud next-generation firewall is a cloud-native solution that provides comprehensive security and visibility across AWS environments, including VPCs, regions, accounts, and workloads. Cloud next-generation firewall is deployed and managed by Palo Alto Networks as a service, eliminating the need for customers to provision, configure, or maintain any infrastructure or software. VM-Series, CN-Series, and Ion-Series are not Palo Alto Networks software firewalls that protect AWS deployments with network security delivered as a managed cloud service, but they are related solutions that can be deployed on AWS or other platforms.

Answer : D

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.

Answer : A, C

The two factors that lead to improved return on investment for prospects interested in Palo Alto Networks virtualized next-generation firewalls (NGFWs) are:

Decreased likelihood of data breach

Reduced time to deploy

Palo Alto Networks virtualized NGFWs are virtualized versions of the Palo Alto Networks next-generation firewall that can be deployed on various cloud or virtualization platforms. Palo Alto Networks virtualized NGFWs provide comprehensive security and visibility across hybrid and multi-cloud environments, protecting applications and data from cyberattacks. By using Palo Alto Networks virtualized NGFWs, prospects can decrease the likelihood of data breach by applying granular security policies based on application, user, content, and threat information, and by leveraging cloud-delivered services such as Threat Prevention, WildFire, URL Filtering, DNS Security, and Cortex Data Lake. By using Palo Alto Networks virtualized NGFWs, prospects can also reduce the time to deploy by taking advantage of automation and orchestration tools such as Terraform, Ansible, CloudFormation, ARM templates, and Panorama plugins that simplify and accelerate the deployment and configuration of firewalls across different cloud platforms. Reduced operational expenditures and reduced insurance premiums are not factors that lead to improved return on investment for prospects interested in Palo Alto Networks virtualized NGFWs, but they may be potential benefits or outcomes of using them.

Answer : B

Geneve is the protocol used for communicating between VM-Series firewalls and a gateway load balancer in Amazon Web Services (AWS). A gateway load balancer is a type of network load balancer that distributes traffic across multiple virtual appliances, such as VM-Series firewalls, in AWS. Geneve is a tunneling protocol that encapsulates the original packet with an additional header that contains metadata about the source and destination endpoints, as well as other information. Geneve allows the gateway load balancer to preserve the original packet attributes and forward it to the appropriate VM-Series firewall for inspection and processing. VRLAN, GRE, and VMLAN are not protocols used for communicating between VM-Series firewalls and a gateway load balancer in AWS, but they are related concepts that can be used for other purposes.

Answer : C

Traffic is directed to a Palo Alto Networks firewall integrated with Cisco ACI through a policy-based redirect. Cisco ACI is a software-defined network (SDN) solution that provides network automation, orchestration, and visibility. A policy-based redirect is a mechanism that allows Cisco ACI to redirect traffic from one endpoint group (EPG) to another EPG through a service device, such as a Palo Alto Networks firewall. The firewall can then inspect and enforce security policies on the redirected traffic before sending it back to Cisco ACI. Traffic is not directed to a Palo Alto Networks firewall integrated with Cisco ACI by using contracts between endpoint groups that send traffic to the firewall using a shared policy, through a virtual machine (VM) monitor domain, or by creating an access policy, as those are not valid methods for traffic redirection in Cisco ACI.
