Paloalto Networks NGFW-Engineer Exam With Confidence Using Practice Dumps

Basic Concept: IPSec implementation planning must include Security policy for tunnel establishment and for decrypted data traffic through the tunnel zone.

Why B and D are Correct: A data-policy pair is required for flows through the tunnel zone, and a policy must permit the IPSec container application to the firewall/local endpoint.

Why A is Wrong: The default interzone-default security policy is sufficient to allow the tunnel negotiation traffic between the firewall and the remote peer. 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: A policy must explicitly permit only the IKE application between the external-facing zone and local zone. 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: Layer 2 interfaces in the same VLAN still depend on zone assignment and intrazone/interzone policy. Same-zone traffic is allowed by intrazone-default unless changed.

Why B is Correct: Placing all three Layer 2 interfaces in the same Layer 2 zone allows same-VLAN communication by default.

Why A is Wrong: Create an Aggregate Ethernet (AE) group that includes all three interfaces. 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: Create an "allow" Security policy with the source and destination VLAN set to "VLAN 20". 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: Create a Layer 3 subinterface for VLAN 20 to enable routing. 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.

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.
