Paloalto Networks NGFW-Engineer Exam With Confidence Using Practice Dumps

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: 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: 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.
