Paloalto Networks NGFW-Engineer Exam With Confidence Using Practice Dumps

Basic Concept: AWS resilient VM-Series architectures normally combine multiple firewall instances, Auto Scaling, and Gateway Load Balancer for horizontal scale and AZ resilience.

Why C is Correct: An EC2 Auto Scaling group with VM-Series firewalls behind an AWS Gateway Load Balancer supports both multi-AZ availability and elastic scale.

Why A is Wrong: AWS Lambda function that monitors the firewall's health and re-routes traffic using the AWS API is a cloud deployment or routing approach, but it does not match the required managed insertion model, resilience pattern, or Panorama-controlled policy design in this scenario.

Why B is Wrong: PAN-OS active/active high availability (HA) pair with an AWS Transit Gateway is a cloud deployment or routing approach, but it does not match the required managed insertion model, resilience pattern, or Panorama-controlled policy design in this scenario.

Why D is Wrong: Single VM-Series firewall with an Elastic IP address that can be re-associated upon failure is a cloud deployment or routing approach, but it does not match the required managed insertion model, resilience pattern, or Panorama-controlled policy design in this scenario.

Basic Concept: GlobalProtect split tunneling can separately control network routes and DNS resolution. Split DNS decides whether queries for specific domains use VPN-assigned DNS servers or local DNS.

Why D is Correct: The Both Network Traffic and DNS option allows selected domains to resolve through corporate DNS while other domains use the endpoint's local resolver.

Why A is Wrong: It specifies when the secondary DNS server is used for resolution to allow access to specific domains that are not managed by the VPN. relates to VPN configuration, but it does not address the specific PAN-OS requirement for selectors, tunnel interface functions, routing, or Security policy in this scenario.

Why B is Wrong: It allows users to access internal resources when connected locally and external resources when connected remotely using the same FQDN. relates to VPN configuration, but it does not address the specific PAN-OS requirement for selectors, tunnel interface functions, routing, or Security policy in this scenario.

Why C is Wrong: It allows devices on a local network to access blocked websites by changing which DNS server resolves certain domain names. relates to VPN configuration, but it does not address the specific PAN-OS requirement for selectors, tunnel interface functions, routing, or Security policy in this scenario.

Basic Concept: Explicit proxy makes the firewall the web proxy endpoint; users configure browsers to send web requests to the firewall, and the firewall creates the upstream server connection.

Why B is Correct: Explicit proxy is correct because it meets the requirement that the firewall, not the workstation, establishes outbound web sessions and enforces authentication.

Why A is Wrong: Transparent proxy is a valid Palo Alto Networks or networking concept in another context, but it does not implement the exact configuration outcome required by this question.

Why C is Wrong: GlobalProtect with User-ID is a valid Palo Alto Networks or networking concept in another context, but it does not implement the exact configuration outcome required by this question.

Why D is Wrong: Decryption policy with Authentication Portal is a valid Palo Alto Networks or networking concept in another context, but it does not implement the exact configuration outcome required by this question.
