Three of the 143 questions in this pack

Question 1

To maintain security efficacy of its public cloud resources by using native tools, a company purchases Cloud NGFW credits to replicate the Panorama, PA-Series, and VM-Series devices used in physical data centers. Resources exist on AWS and Azure:

• The AWS deployment is architected with AWS Transit Gateway, to which all resources connect.

• The Azure deployment is architected with each application independently routing traffic.

The engineer deploying Cloud NGFW in these two cloud environments must account for the following:

• Minimize changes to the two cloud environments.

• Scale to the demands of the applications while using the least amount of compute resources.

• Allow the company to unify the Security policies across all protected areas.

Which two implementations will meet these requirements? (Choose two.)

  1. Deploy a VM-Series firewall in AWS in each VPC, create an IPSec tunnel between AWS and Azure, and manage the policy with Panorama.
  2. Deploy Cloud NGFW for Azure in vNET/s, update the vNET/s routing to path traffic through the deployed NGFWs, and manage the policy with Panorama.
  3. Deploy Cloud NGFW for Azure in vWAN, create a vWAN to route all appropriate traffic to the Cloud NGFW attached to the vWAN, and manage the policy with local rules.
  4. Deploy Cloud NGFW for AWS in a centralized Security VPC, update the Transit Gateway to route all appropriate traffic through the Security VPC, and manage the policy with Panorama.
Show answer and explanation

Correct answer: B, D. Deploy Cloud NGFW for Azure in vNET/s, update the vNET/s routing to path traffic through the deployed NGFWs, and manage the policy with Panorama; Deploy Cloud NGFW for AWS in a centralized Security VPC, update the Transit Gateway to route all appropriate traffic through the Security VPC, and manage the policy with Panorama.

Each cloud keeps its existing routing design. In Azure, where every application routes independently, Cloud NGFW for Azure is deployed in the vNETs and the vNET routing is updated to send traffic through it, so no new transit architecture is introduced. In AWS, where everything already attaches to the Transit Gateway, Cloud NGFW for AWS sits in a centralized Security VPC and the Transit Gateway route tables steer traffic through it. Cloud NGFW is a managed service that scales with application demand without the customer sizing and running firewall instances, and managing both deployments from Panorama lets one set of Security policies cover the cloud resources and the existing PA-Series and VM-Series firewalls.

Why the other options are wrong

  • A. A VM-Series firewall in every VPC consumes more compute than a centralized managed service, and an IPSec tunnel between AWS and Azure adds infrastructure the requirements do not call for.
  • C. Building a vWAN changes the Azure routing design, and managing policy with local rules keeps it separate from Panorama, so policy is not unified across all protected areas.

Question 2

During an upgrade to the routing infrastructure in a customer environment, the network administrator wants to implement Advanced Routing Engine (ARE) on a Palo Alto Networks firewall.

Which firewall models support this configuration?

  1. PA-5280, PA-7080, PA-3250, VM-Series
  2. PA-455, VM-Series, PA-1410, PA-5450
  3. PA-3260, PA-5410, PA-850, PA-460
  4. PA-7050, PA-1420, VM-Series, CN-Series
Show answer and explanation

Correct answer: A. PA-5280, PA-7080, PA-3250, VM-Series

The Advanced Routing Engine replaces the legacy virtual router with logical routers and an industry-standard routing configuration. Its supported platforms include the PA-7000 Series, PA-5200 Series and PA-3200 Series hardware and VM-Series firewalls, so the PA-7080, PA-5280, PA-3250 and VM-Series in this list can all enable Advanced Routing and use logical routers for static routes, BGP, OSPF and redistribution. Enabling it is a General Settings change followed by a commit and a reboot, after which the firewall uses the Advanced Routing Engine in place of the legacy routing engine.

Why the other options are wrong

  • B. This list pairs VM-Series with PA-455, PA-1410 and PA-5450 models instead of the PA-7000, PA-5200 and PA-3200 Series hardware described above.
  • C. The PA-850 belongs to the PA-800 Series, which is not on the Advanced Routing Engine platform list, so this set of models cannot all run logical routers.
  • D. This list pairs the PA-7050 and VM-Series with the PA-1420 and the container-based CN-Series instead of the PA-5200 and PA-3200 Series hardware described above.

Question 3

Which two statements apply to configuring required security rules when setting up an IPSec tunnel between a Palo Alto Networks firewall and a third-party gateway? (Choose two.)

  1. For incoming and outgoing traffic through the tunnel, creating separate rules for each direction is optional.
  2. The IKE negotiation and IPSec/ESP packets are allowed by default via the intrazone default allow policy.
  3. For incoming and outgoing traffic through the tunnel, separate rules must be created for each direction.
  4. The IKE negotiation and IPSec/ESP packets are denied by default via the interzone default deny policy.
Show answer and explanation

Correct answer: A, B. For incoming and outgoing traffic through the tunnel, creating separate rules for each direction is optional; The IKE negotiation and IPSec/ESP packets are allowed by default via the intrazone default allow policy.

IKE negotiation and IPSec ESP packets between the firewall and the third-party peer arrive on the external interface and terminate on the firewall's own address in that same zone, so they match the intrazone default allow rule and need no additional rule for the tunnel to establish. For the traffic carried inside the tunnel, writing a separate rule for each direction is a choice made for granular control of incoming and outgoing traffic, not a requirement: a single rule that lists both the internal zone and the tunnel zone as source and destination can permit traffic in both directions.

Why the other options are wrong

  • C. Separate rules per direction are only needed when granular control is wanted, because one rule containing both zones as source and destination can cover traffic in both directions.
  • D. IKE and ESP between the peer and the firewall's external interface stay within one zone, so they match the intrazone default allow rule rather than the interzone default deny rule.

What makes the NGFW Engineer exam hard

This is the exam that replaced PCNSE. Palo Alto Networks retired the whole PCNSE, PCNSA and PCCET family in 2025 and rebuilt the portfolio around job roles, and the Next-Generation Firewall Engineer is now the firewall engineering credential. A PCNSE bank is not a shortcut: the new blueprint has three domains where PCNSE had six, and 80% of the marks sit in two of them.

PAN-OS Networking Configuration and PAN-OS Device Setting Configuration are 40% each. Networking covers Layer 2, Layer 3, virtual wire, tunnel, aggregate and management interfaces, zones, active/active and active/passive HA with link and path monitoring, dynamic routing, redistribution, route monitoring and the Advanced Routing Engine, GlobalProtect portals, gateways, authentication and split tunnelling, and IPsec, GRE and quantum-resistant cryptography. Device settings covers authentication roles, profiles and sequences, virtual systems with virtual and logical routers and inter-VSYS routing, Strata Logging Service, log forwarding and collector groups, software updates, PKI and decryption certificates, SSL/TLS profiles, on-premises and Cloud Identity Engine User-ID with group mapping and redistribution, and the PAN-OS web proxy. Integration and Automation at 20% is where it departs furthest from PCNSE: PA-Series, VM-Series, CN-Series, Cloud NGFW and AI Runtime Security deployment, API-driven deployment, Kubernetes, hypervisors, CSPs, Terraform and Ansible, Panorama templates, device groups and pre and post rulesets, and ACC dashboards and custom reports.
