Palo Alto Networks Next-Generation Firewall Engineer Sample Questions (Q92-Q97):

NEW QUESTION # 92
An engineer configures a PA-440 firewall to act as a switch by creating several Layer 2 interfaces and assigning them all to VLAN 20. A file server is connected to interface ethernet1/1, and client workstations are connected to interfaces ethernet1/2 and ethemet1/3. All devices are in VLAN 20. The clients are unable to access the file server.
Which configuration step to allow this communication by default is missing?

Answer: D

Explanation:
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.


NEW QUESTION # 93
An NGFW engineer is configuring multiple Layer 2 interfaces on a Palo Alto Networks firewall, and all interfaces must be assigned to the same VLAN. During initial testing, it is reported that clients located behind the various interfaces cannot communicate with each other.
Which action taken by the engineer will resolve this issue?

Answer: A

Explanation:
In a Palo Alto Networks Layer 2 deployment, the firewall acts as a transparent bridge between network segments. To facilitate this, the engineer must first create aVLAN objectand assign the physical Layer 2 interfaces to it. While the VLAN object handles the MAC-address learning and switching logic, the firewall's security engine still requires that these interfaces be assigned toSecurity Zonesto enforce traffic inspection.
The reason clients cannot communicate in the described scenario is rooted in the firewall'szone-based policy architecture. Even if multiple interfaces belong to the same logical VLAN, if those interfaces are assigned to different security zones (e.g., "L2-Finance" and "L2-HR"), the firewall treats the traffic as inter-zone. By default, theinterzone-defaultsecurity policy is set toDeny. Therefore, even though the traffic is staying within the same broadcast domain (VLAN), the firewall will drop the packets unless a specific Security Policy is created to permit traffic between those zones.
Option C is the correct resolution because it acknowledges that "appropriate" zone assignment often involves segmentation for security purposes. Once segmented, explicit policies are mandatory. Options A and D are incorrect becauseIP routingis a Layer 3 function and is not used for Layer 2 interfaces, which do not have IP addresses assigned to the physical interfaces themselves.


NEW QUESTION # 94
An NGFW engineer is establishing bidirectional connectivity between the accounting virtual system (VSYS) and the marketing VSYS. The traffic needs to transition between zones without leaving the firewall (no external physical connections). The interfaces for each VSYS are assigned to separate virtual routers (VRs), and inter-VR static routes have been configured. An external zone has been created correctly for each VSYS. Security policies have been added to permit the desired traffic between each zone and its respective external zone. However, the desired traffic is still unable to successfully pass from one VSYS to the other in either direction.
Which additional configuration task is required to resolve this issue?

Answer: B

Explanation:
In Palo Alto Networks firewalls, each virtual system (VSYS) is typically isolated from other VSYSs, meaning that traffic between different VSYSs cannot pass through the firewall by default. In this case, since the interfaces for each VSYS are assigned to separate virtual routers (VRs), and the desired traffic is still not passing between the two VSYSs, the firewall needs to be explicitly configured to allow traffic between them.
The required configuration is to add each VSYS to the list of visible virtual systems of the other VSYS. This allows inter-VSYS communication to be enabled, effectively permitting the traffic to pass between the zones of different VSYSs.


NEW QUESTION # 95
An engineer is configuring a site-to-site IPSec VPN to a partner network. The IKE Gateway and IPSec tunnel configurations are complete, and the tunnel interface has been assigned to a security zone. However, the tunnel fails to establish, and no application traffic passes through it once it is up. Which two Security policy configurations are required to allow tunnel establishment and data traffic flow in this scenario? (Choose two answers)

Answer: A,D

Explanation:
Establishing a functional IPSec VPN on a Palo Alto Networks Next-Generation Firewall requires addressing two distinct traffic flows: the management of the tunnel itself (Control Plane) and the transit of protected data (Data Plane).
First, to address the failure of the tunnel to establish, the firewall must have a security policy that permits the negotiation protocols. Specifically, a rule is required to allowike(UDP/500),ipsec-esp-udp(UDP/4500 if NAT- T is used), andipsec-esp(IP Protocol 50) between the source zone (where the firewall's public-facing interface resides) and the destination zone (where the partner's gateway resides). Since the firewall is the endpoint for this negotiation, the destination zone is often the "local" zone or the specific external zone where the peer's IP is located.
Second, once the tunnel is established, the firewall must be configured to allow the actual application traffic.
In the Palo Alto Networks zone-based architecture, traffic entering or exiting an IPSec tunnel is associated with aTunnel Interface. This interface must be assigned to a security zone. Because the default behavior for interzone traffic is to "Deny," the engineer must explicitly create a pair of security rules: one to allow traffic from the internal network zone to the tunnel interface's zone, and another to allow returning traffic from the tunnel interface's zone back to the internal zone. Without these rules, the tunnel may appear "active" in the logs, but all encapsulated production data will be dropped.


NEW QUESTION # 96
An NGFW engineer is configuring multiple Panorama-managed firewalls to start sending all logs to Strata Logging Service. The Strata Logging Service instance has been provisioned, the required device certificates have been installed, and Panorama and the firewalls have been successfully onboarded to Strata Logging Service.
Which configuration task must be performed to start sending the logs to Strata Logging Service and continue forwarding them to the Panorama log collectors as well?

Answer: C

Explanation:
Basic Concept: Strata Logging Service can receive logs from Panorama-managed firewalls while existing on- premises Panorama log collection is retained. Dual forwarding requires duplicate logging rather than replacing the existing destination.
Why C is Correct: Enable Duplicate Logging is correct because it sends copies to both Strata Logging Service and Panorama/on-premises log collectors instead of moving logs only to the cloud.
Why A is Wrong: Changing Log Forwarding profile match lists is not the required global/template step for preserving both cloud and on-premises log destinations.
Why B is Wrong: The named option is not the duplicate logging control required to send a copy of logs to both locations.
Why D is Wrong: Enable Cloud Logging sends logs to Strata Logging Service, but by itself it does not preserve on-premises Panorama log collector delivery.
