NGFW-Engineer Exam Dumps - Palo Alto Networks Next-Generation Firewall Engineer

Terraform is an Infrastructure-as-Code (IaC) tool that automates the provisioning and management of infrastructure resources, including Palo Alto Networks Next-Generation Firewalls (NGFWs). By using Terraform configuration files, administrators can define and deploy NGFW instances across cloud environments (such as AWS, Azure, and GCP) efficiently and consistently.

Terraform enables:

Automated firewall deployment in cloud environments.

Configuration of security policies and networking settings in a declarative manner.

Scalability and repeatability, reducing manual intervention in firewall provisioning.

The maximum number of Log Collectors that can be added to a Log Collector Group is 18 plus 2 hot spares, ensuring redundancy and availability in case of failure. This allows for a total of up to 20 Log Collectors in a group, providing sufficient scalability and reliability for log collection.

Use of dynamic routing protocols: An IP address is needed on the tunnel interface to participate in dynamic routing protocols (like OSPF, BGP, etc.) over the tunnel. This allows the firewall to advertise routes and receive updates over the tunnel.

Tunnel monitoring: The IP address on the tunnel interface can also be used for monitoring the tunnel's status. Tunnel monitoring (such as IPSec tunnel monitoring) requires an IP address on the tunnel interface to check the health and availability of the tunnel.

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 the preemptive hold time is set to 0 minutes in route monitoring, the firewall is configured to immediately reinstall the route into the Routing Information Base (RIB) as soon as the monitored path comes up. This essentially means that the firewall will not wait for any predefined hold time before reestablishing the route once the monitoring condition is met, ensuring a faster recovery of the route.

Palo Alto Networks Next-Generation Firewalls (NGFWs) use SSL/TLS profiles to secure connections for services such as GlobalProtect Gateways and GlobalProtect Portals. These profiles are used to manage the SSL/TLS encryption and decryption for secure communication between the firewall and clients (such as VPN clients for GlobalProtect). This helps ensure the confidentiality and integrity of the data during transmission.
