Palo Alto Networks NGFW-Engineer Exam Syllabus Topics:

Topic
Details

Topic 1

PAN-OS Device Setting Configuration: This section evaluates the expertise of System Administrators in configuring device settings on PAN-OS. It includes implementing authentication roles and profiles, and configuring virtual systems with interfaces, zones, routers, and inter-VSYS security. Logging mechanisms such as Strata Logging Service and log forwarding are covered alongside software updates and certificate management for PKI integration and decryption. The section also focuses on configuring Cloud Identity Engine User-ID features and web proxy settings.

Topic 2

Integration and Automation: This section measures the skills of Automation Engineers in deploying and managing Palo Alto Networks NGFWs across various environments. It includes the installation of PA-Series, VM-Series, CN-Series, and Cloud NGFWs. The use of APIs for automation, integration with third-party services like Kubernetes and Terraform, centralized management with Panorama templates and device groups, as well as building custom dashboards and reports in Application Command Center (ACC) are key topics.

Topic 3

PAN-OS Networking Configuration: This section of the exam measures the skills of Network Engineers in configuring networking components within PAN-OS. It covers interface setup across Layer 2, Layer 3, virtual wire, tunnel interfaces, and aggregate Ethernet configurations. Additionally, it includes zone creation, high availability configurations (active
active and active
passive), routing protocols, and GlobalProtect setup for portals, gateways, authentication, and tunneling. The section also addresses IPSec, quantum-resistant cryptography, and GRE tunnels.

Palo Alto Networks Next-Generation Firewall Engineer Sample Questions (Q23-Q28):

NEW QUESTION # 23
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.)

A. The IKE negotiation and IPSec/ESP packets are denied by default via the interzone default deny policy.
B. For incoming and outgoing traffic through the tunnel, creating separate rules for each direction is optional.
C. For incoming and outgoing traffic through the tunnel, separate rules must be created for each direction.
D. The IKE negotiation and IPSec/ESP packets are allowed by default via the intrazone default allow policy.

Answer: A,C

Explanation:
Separate rules must be created for each direction: Palo Alto Networks firewalls enforce security policies based on traffic direction. To allow bidirectional communication through the IPSec tunnel, two separate rules are required - one for incoming and one for outgoing traffic.
IKE negotiation and IPSec/ESP packets are denied by default: Palo Alto Networks firewalls use an interzone default deny policy, meaning that unless an explicit policy allows IKE (UDP 500/4500) and ESP (protocol 50) traffic, the firewall will block these packets, preventing tunnel establishment. Therefore, administrators must create explicit rules permitting IKE and IPSec/ESP traffic to the firewall's external interface.

NEW QUESTION # 24
In a hybrid cloud deployment, what is the primary function of Ansible in managing Palo Alto Networks NGFWs?

A. It facilitates dynamic updates to NGFW threat databases.
B. It provides a web interface for managing NGFW hardware clusters.
C. It automates NGFW policy updates and configurations through playbooks.
D. It enables centralized log collection and correlation for NGFWs.

Answer: C

Explanation:
In a hybrid cloud deployment, Ansible is primarily used for automating configurations and policy updates on Palo Alto Networks Next-Generation Firewalls (NGFWs). Through the use of playbooks, Ansible can automate the process of deploying security policies, updating configurations, and managing the firewall's state, which enhances efficiency and consistency across multiple NGFWs in a large or hybrid cloud environment.

NEW QUESTION # 25
An NGFW engineer is establishing bidirectional connectivity between the accounting virtual system (VSYS) and the marketing VSYS. The traffic needs to transition between zones without leaving the firewall (no external physical connections). The interfaces for each VSYS are assigned to separate virtual routers (VRs), and inter-VR static routes have been configured. An external zone has been created correctly for each VSYS. Security policies have been added to permit the desired traffic between each zone and its respective external zone. However, the desired traffic is still unable to successfully pass from one VSYS to the other in either direction.
Which additional configuration task is required to resolve this issue?

A. Create Security policies to allow the traffic between the two external zones.
B. Create a transit VSYS and route all inter-VSYS traffic through it.
C. Add each VSYS to the list of visible virtual systems of the other VSYS.
D. Enable the "allow inter-VSYS traffic" option in both external zone configurations.

Answer: C

Explanation:
In Palo Alto Networks firewalls, each virtual system (VSYS) is typically isolated from other VSYSs, meaning that traffic between different VSYSs cannot pass through the firewall by default. In this case, since the interfaces for each VSYS are assigned to separate virtual routers (VRs), and the desired traffic is still not passing between the two VSYSs, the firewall needs to be explicitly configured to allow traffic between them.
The required configuration is to add each VSYS to the list of visible virtual systems of the other VSYS. This allows inter-VSYS communication to be enabled, effectively permitting the traffic to pass between the zones of different VSYSs.

NEW QUESTION # 26
Which PAN-OS method of mapping users to IP addresses is the most reliable?

A. GlobalProtect
B. Port mapping
C. Syslog
D. Server monitoring

Answer: D

Explanation:
Server monitoring is the most reliable method for mapping users to IP addresses in PAN-OS. This method allows the firewall to monitor specific servers, such as Microsoft Active Directory (AD) or LDAP servers, to dynamically retrieve and update user-to-IP mappings. It provides a more accurate and up-to-date mapping of users to their associated IP addresses, as it directly queries user databases in real time.

NEW QUESTION # 27
In a Palo Alto Networks environment, GlobalProtect has been enabled using certificate-based authentication for both users and devices. To ensure proper validation of certificates, one or more certificate profiles are configured.
What function do certificate profiles serve in this context?

A. They allow the firewall to bypass certificate validation entirely, focusing only on username / password-based authentication.
B. They define trust anchors (root / intermediate Certificate Authorities (CAs)), specify revocation checks (CRL/OCSP), and map certificate attributes (e.g., CN) for user or device authentication.
C. They provide a one-click mechanism to distribute certificates to all endpoints without relying on external enrollment methods.
D. They store private keys for users and devices, effectively allowing the firewall to issue or reissue certificates if the primary Certificate Authority (CA) becomes unavailable, providing a built-in fallback CA to maintain continuous certificate issuance and authentication.

Answer: B

Explanation:
In the context of GlobalProtect with certificate-based authentication, certificate profiles are used to ensure proper validation of the certificates. They perform the following functions:
Define trust anchors, which are the root and intermediate Certificate Authorities (CAs) that the firewall trusts to authenticate certificates.
Specify revocation checks, such as CRL (Certificate Revocation List) and OCSP (Online Certificate Status Protocol), to ensure that the certificates being used have not been revoked.
Map certificate attributes, such as the Common Name (CN), which helps in authenticating users and devices based on their certificates.
