Free Practice Questions for Paloalto Networks NGFW-Engineer Exam

When integrating Kubernetes with Palo Alto Networks NGFWs, the CN-Series firewalls are specifically designed to secure traffic between microservices in containerized environments. These firewalls provide advanced security features like Application Identification (App-ID), URL filtering, and Threat Prevention to secure communication between containers and microservices within a Kubernetes environment.

When implementing a new self-signed root certificate authority (CA) for SSL decryption on a Palo Alto Networks firewall, the subordinate CA certificate (which is generated by the firewall) must be imported into the trust stores of all client devices. This ensures that client devices trust the firewall as a valid certificate authority, enabling the firewall to decrypt and re-encrypt SSL traffic.

Importing the subordinate CA certificate into the client devices' trust stores is necessary for those devices to trust the new self-signed root CA and properly handle SSL decryption traffic.

When configuring a new security zone on a Palo Alto Networks firewall, the two valid zone types are:

Tunnel: A Tunnel zone is used for traffic that is associated with a VPN tunnel, such as IPSec tunnels. Traffic passing through a tunnel interface is classified into this zone.

Virtual Wire: A Virtual Wire zone is used when a firewall operates in transparent mode (also known as Layer 2 mode). In this configuration, the firewall can inspect traffic without modifying the IP address structure of the network.

Assigning an Admin Role Profile to a user in a Palo Alto Networks NGFW is used to define granular permissions for management tasks. This allows administrators to control what actions a user can perform on the firewall, such as configuration changes, monitoring, and logging. By assigning different admin roles, you can ensure that users have access only to the areas and tasks they need, enforcing the principle of least privilege.

To meet the company's requirements - minimizing changes to the cloud environments, optimizing compute resources, and unifying security policies - the best approach is to deploy Cloud NGFW solutions natively for AWS and Azure while managing policies centrally with Panorama.

In Azure, using Cloud NGFW for Azure deployed within vNETs allows traffic to be routed through security appliances efficiently without requiring a complete re-architecture. This approach aligns with Azure's existing routing mechanism while maintaining security.

In AWS, deploying Cloud NGFW for AWS in a centralized Security VPC and integrating it with AWS Transit Gateway enables traffic inspection for all connected VPCs without modifying individual workloads. This method ensures efficient scaling and minimal infrastructure changes while maintaining security consistency.

This approach meets all the requirements for securing east-west traffic within each Kubernetes cluster, maintaining consistent security policies across on-premises and cloud environments, and allowing for dynamic scaling of the CN-Series NGFWs as containerized workloads spin up or down. By using Kubernetes-native deployment tools (such as Helm), the CN-Series NGFWs can be deployed and scaled dynamically within each cluster. Local insertion into the service mesh or CNI ensures that the NGFW can inspect traffic at the appropriate points within the cluster.

Centralized management via Panorama ensures that security policies are uniform across both on-premises and cloud environments, providing visibility and control across all clusters.

In a High Availability (HA) active/passive pair configuration, when setting up an Aggregate Ethernet (AE) interface, enabling the "Enable in HA Passive State" option allows the interface to participate in LACP (Link Aggregation Control Protocol) even when the system is in the passive state. This ensures that the pre-negotiation of the LACP link occurs, allowing the link aggregation to be ready as soon as the firewall becomes active.

To enable the Advanced Routing Engine (ARE) on a Palo Alto Networks firewall, the license for the ARE must be applied first. Without the proper license, the firewall cannot activate and use the advanced routing features provided by ARE, such as support for more complex routing protocols (e.g., BGP, OSPF, etc.).

Once the license is applied and validated, the routing engine can be configured, allowing the creation of logical routers and routing policies.

To begin sending logs to Strata Logging Service while continuing to forward them to Panorama log collectors, the necessary configuration is to enable Cloud Logging. This option is configured in the Cloud Logging section under Device → Setup → Management in the appropriate templates. Once enabled, this ensures that logs are directed both to the Strata Logging Service (cloud) and to the Panorama log collectors.
