Paloalto Networks NGFW-Engineer Exam With Confidence Using Practice Dumps

Basic Concept: Static route monitoring removes and reinstalls routes based on monitored path state. Preemptive hold time controls the delay before a recovered primary route is reinstalled.

Why D is Correct: A value of 0 causes immediate preemption: as soon as the monitored path comes back up, the firewall reinstalls the static route in the RIB without waiting.

Why A is Wrong: It does not accept the configuration. is a routing-related concept, but it is not the PAN-OS routing attribute, prerequisite, or route-selection behavior required by this question.

Why B is Wrong: It accepts the configuration but throws a warning message. is a routing-related concept, but it is not the PAN-OS routing attribute, prerequisite, or route-selection behavior required by this question.

Why C is Wrong: It removes the static route because 0 is a NULL value. is a routing-related concept, but it is not the PAN-OS routing attribute, prerequisite, or route-selection behavior required by this question.

Basic Concept: PAN-OS security zones have specific types that correspond to interface operating modes. Valid zone types include Layer 2, Layer 3, Virtual Wire, Tap, Tunnel, and External depending on the design.

Why A and D are Correct: Tunnel and Virtual Wire are valid selectable zone types and are used for VPN/tunnel interfaces and inline transparent virtual wire deployments respectively.

Why B is Wrong: Intrazone is a default policy concept for traffic inside the same zone. It is not a selectable security zone type.

Why C is Wrong: Internal is commonly used as a zone name, but PAN-OS zone type is based on interface mode, not business naming.

Basic Concept: When interoperating with policy-based VPN devices such as Cisco ASA or Check Point, Proxy IDs identify the local and remote selectors that must match Phase 2/IPSec SAs.

Why B is Correct: Matching Proxy IDs resolves the failure because the ASA expects specific encryption domains; without matching selectors, IKE Phase 2 negotiation fails or traffic does not match the correct SA.

Why A is Wrong: Ensure that an active static or dynamic route exists for the VPN peer with next hop as the tunnel interface. 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: Check that IPSec is enabled in the management profile on the external interface. 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 D is Wrong: Validate the tunnel interface VLAN against the peer’s configuration. 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.
