NGFW-Engineer Exam Dumps - Paloalto Networks Network Security Administrator Questions and Answers

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.

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.

Local firewall rules are evaluated after Panorama pre-rules (those applied before the firewall’s local policies) and before Panorama post-rules (those applied after the firewall’s local policies). This ensures that the local firewall rules do not override the central Panorama policy and are only applied in the appropriate order within the policy evaluation sequence.

When configuring a new firewall virtual system (VSYS) on a Palo Alto Networks firewall, one of the resources that can be assigned is the sessions limit. This setting allows the administrator to control the number of active sessions that can be handled by the VSYS, ensuring that each virtual system has an appropriate allocation of resources based on its needs.

In a hybrid authentication model with both certificate-based authentication for pre-logon and SAML-based multi-factor authentication (MFA) for user logon, the GlobalProtect agent processes the flow as follows:

During the pre-logon stage, the agent uses the machine certificate to authenticate and establish the initial VPN tunnel.

Once the user logs in (after the machine is connected), the agent then triggers SAML-based MFA to ensure the user is authenticated with multi-factor authentication, validating both the device and the user identity before granting full access.

This method ensures that both the device and user are properly authenticated and validated in the hybrid authentication model.

The phases of the Palo Alto Networks AI Runtime Security: Network Intercept solution are designed to help identify and protect against potential threats in real time by using AI to detect and prevent malicious activities within the network.

Discovery: Identifying applications, services, and behaviors within the network to understand baseline activity.

Deployment: Implementing the solution into the network and integrating with existing security measures.

Detection: Monitoring traffic and activities to identify abnormal or malicious behavior.

Prevention: Taking action to stop threats once detected, such as blocking malicious traffic or stopping exploit attempts.

To configure the management interface as a DHCP client on a Palo Alto Networks NGFW, the correct CLI command is set deviceconfig management type dhcp-client.

This command configures the management interface to obtain an IP address dynamically using DHCP.

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.

In Panorama, without performing a context switch, the administrator can perform local configuration tasks directly on the connected firewall. The following operations can be done:

Modification of local security rules: Security rules can be modified directly on the connected firewall from the Panorama GUI.

Modification of a Layer 3 interface: Changes to the Layer 3 interfaces on the connected firewall can be done from Panorama, without needing to switch to the firewall's local interface.

Modification of the firewall device hostname: The firewall's hostname can be changed via Panorama.

When split tunneling is enabled with the "Both Network Traffic and DNS" option in the GlobalProtect portal configuration, it allows the firewall to control which traffic is sent over the VPN tunnel and which is not. Specifically, it determines which domains are resolved by the VPN-assigned DNS servers (for domains requiring VPN access) and which are resolved by local DNS servers (for domains that can be accessed without the VPN tunnel).
