Question 1

A customer would like to support Apple Bonjour in their environment for ease of configuration.
Which type of interface in needed on their PA-3200 Series firewall to enable Bonjour Reflector in a
segmented network?

Accepted Answer

C

Explanation: The primary purpose of the Bonjour Reflector on a Palo Alto Networks firewall is to forward Bonjour (mDNS) traffic across different subnets. In a "segmented network," devices are separated into different broadcast domains, which are Layer 3 boundaries. The Bonjour protocol itself is link-local and does not cross these boundaries. To enable service discovery between these segments, the firewall must act as a router and forward this traffic. This is achieved by enabling the Bonjour Reflector on the Layer 3 interfaces that serve as the gateways for each network segment, allowing them to relay the mDNS packets between subnets.

Question 2

A superuser is tasked with creating administrator accounts for three contractors. For compliance
purposes, all three contractors will be working with different device-groups in their hierarchy to
deploy policies and objects
Which type of role-based access is most appropriate for this project?

Accepted Answer

C

Explanation: The most appropriate solution is to use the predefined "Device Group and Template Admin" role. This role is specifically designed to grant administrators the necessary permissions to manage policies and objects within the context of device groups and templates. To meet the compliance requirement of segregating access, the superuser would assign this role to each of the three contractor accounts and then configure the "Access Domain" for each account to specify the unique device group that the respective contractor is authorized to manage. This method directly addresses the scenario using a standard, purpose-built role, enforcing the principle of least privilege.

Question 3

An engineer configures SSL decryption in order to have more visibility to the internal users' traffic
when it is regressing the firewall.
Which three types of interfaces support SSL Forward Proxy? (Choose three.)

Accepted Answer

B, C, E

Explanation: SSL Forward Proxy requires the firewall to be deployed inline to intercept, decrypt, and re-encrypt traffic. Layer 3, Layer 2, and Virtual Wire are all inline deployment modes that process transit traffic. Security policies, including Decryption policies, can be applied to traffic flowing through these interface types, allowing the firewall to act as the required man-in-the-middle for SSL Forward Proxy.

Question 4

An administrator needs to build Security rules in a Device Group that allow traffic to specific users and groups defined in Active Directory. What must be configured in order to select users and groups for those rules from Panorama?

Accepted Answer

D

Explanation: To create Security policies in Panorama that reference Active Directory groups, Panorama must first be aware of those groups. Panorama itself does not directly query the directory server. Instead, you must designate a managed firewall as the "master device" for the device group. This master device is configured with Group Mapping settings to connect to the LDAP server (Active Directory). It retrieves the list of available groups and provides this list to Panorama. Panorama then uses this information to populate the user/group fields in the policy editor, allowing the administrator to build the rules.

Question 5

How should an administrator enable the Advance Routing Engine on a Palo Alto Networks firewall?

Accepted Answer

C

Explanation: According to PAN-OS documentation, the Advanced Routing Engine is a global firewall setting. It is enabled from Device > Setup > Management > General Settings by checking “Enable Advanced Routing Engine,” followed by a commit and firewall reboot. Only after this global toggle is on can individual virtual-router objects use the new engine. Therefore, option C is the only path that actually turns the feature on.

Question 6

A firewall engineer needs to update a company's Panorama-managed firewalls to the latest version of PAN-OS. Strict security requirements are blocking internet access to Panorama and to the firewalls. The PAN-OS images have previously been downloaded to a secure host on the network. Which path should the engineer follow to deploy the PAN-OS images to the firewalls?

Accepted Answer

D

Explanation: In a Panorama-managed environment where direct internet access is unavailable, the PAN-OS software image must first be manually uploaded to Panorama from a local host. The correct administrative path in the Panorama web interface to manage and deploy operating system software to managed firewalls is Panorama > Device Deployment > Software. From this section, an administrator can upload the pre-downloaded image file and then push it to the designated firewalls for installation. This process centralizes the upgrade for all managed devices without requiring them to have individual internet connectivity.

Question 7

Which three multi-factor authentication methods can be used to authenticate access to the firewall? (Choose three.)

Accepted Answer

C, D, E

Explanation: Palo Alto Networks firewalls enhance administrative access security by supporting multi-factor authentication (MFA). This is accomplished through native configurations and integrations with external authentication servers. The firewall can be configured to require a user certificate (a "something you have" factor) in addition to a password. It also integrates with external MFA platforms via RADIUS or SAML. These platforms commonly provide authentication using one-time passwords (OTPs) generated by authenticator apps or hardware tokens, and SMS messages containing verification codes. These three methods—SMS, user certificate, and OTP—are all established mechanisms for implementing MFA for firewall administrators.

Question 8

PBF can address which two scenarios? (Choose two.)

Accepted Answer

A, B

Explanation: Policy-Based Forwarding (PBF) allows administrators to create forwarding policies that override the firewall's route table. A primary use case is to route specific traffic, such as a high-bandwidth application like FTP, over a secondary or backup ISP link to preserve bandwidth on the primary link. Another key capability is providing resiliency; PBF rules can be configured with path monitoring. If the primary path becomes unavailable, the PBF rule can be disabled, allowing traffic to failover to a secondary path defined either in another PBF rule or in the main routing table, thus maintaining application connectivity.

Question 9

An administrator Just enabled HA Heartbeat Backup on two devices However, the status on tie firewall's dashboard is showing as down High Availability. https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/PCNSE_Dumps/page_22_img_1.jpg What could an administrator do to troubleshoot the issue?

Accepted Answer

B

Explanation: The High Availability (HA) Heartbeat Backup feature uses ICMP pings between the management interfaces of the two firewalls to provide a secondary path for failure detection. If the management interface is configured with an access control list (the "Permitted IP Addresses" list), it must explicitly allow traffic from the peer firewall's management IP address. If the peer's IP is not on this list, the heartbeat pings will be dropped, and the firewall will report the Heartbeat Backup link status as "down". Checking this permit list is a critical troubleshooting step for this specific issue.

Question 10

A firewall administrator is investigating high packet buffer utilization in the company firewall. After
looking at the threat logs and seeing many flood attacks coming from a single source that are
dropped by the firewall, the administrator decides to enable packet buffer protection to protect
against similar attacks.
The administrator enables packet buffer protection globally in the firewall but still sees a high packet
buffer utilization rate.
What else should the administrator do to stop packet buffers from being overflowed?

Accepted Answer

C

Explanation: Packet buffer protection must be explicitly enabled for the zones where it is needed, in addition to the global setting. The global setting (under Device > Setup > Session) acts as a master switch, but the protection is not active on any specific zone until it is configured for that zone. This is accomplished by configuring packet buffer protection within a Zone Protection Profile and applying that profile to the ingress zone(s) receiving the attack traffic. The administrator's action of enabling it globally was insufficient because the protection was not yet applied to the specific, affected zone.

Question 11

An engineer is troubleshooting a traffic-routing issue. What is the correct packet-flow sequence?

Accepted Answer

C

Explanation: The Palo Alto Networks firewall processes packets in a specific, logical order. For a new session (slow path), the firewall first checks for a matching Policy-Based Forwarding (PBF) rule to determine if a special forwarding path is required. If no PBF rule matches, the firewall performs a standard route lookup in the virtual router's table to find the best route, which could be a static route. After the forwarding decision is made (determining the egress interface and zone) and any applicable NAT policy is evaluated, the firewall enforces the security policy to allow or deny the session. This sequence ensures routing is decided before the security posture is evaluated.

Question 12

Which two actions must an engineer take to configure SSL Forward Proxy decryption? (Choose two.)

Accepted Answer

B, C

Explanation: To enable SSL Forward Proxy, the firewall must intercept traffic between a client and a server. This requires two fundamental configurations. First, a Forward Trust Certificate (B) must be generated on the firewall and deployed to clients. This allows the client's browser to trust the certificate the firewall presents when it impersonates the external server. Second, a Decryption policy rule (C) must be created to define which specific traffic sessions should be decrypted. Without this rule, the firewall will not apply decryption to any traffic, even if a certificate is present.

Question 13

A firewall administrator is configuring an IPSec tunnel between Site A and Site B. The Site A firewall
uses a DHCP assigned address on the outside interface of the firewall, and the Site B firewall uses a
static IP address assigned to the outside interface of the firewall. However, the use of dynamic
peering is not working.
Refer to the two sets of configuration settings provided. Which two changes will allow the
configurations to work? (Choose two.)
Site A configuration:
PCNSE practice exam questions

Accepted Answer

C, D

Explanation: The configuration for Site A, which has a dynamic IP address, contains two fundamental errors that prevent the IPSec tunnel from establishing. 1. Passive Mode: The Site A firewall is configured with "Enable Passive Mode." In a dynamic-to-static IP VPN, the peer with the dynamic address (Site A) must always initiate the connection because the static peer (Site B) does not know its current IP address. Passive mode prevents Site A from initiating, which is a fatal error for this scenario. 2. IKE Version Mismatch: The Site A configuration is set to "IKEv2 preferred mode" and uses an FQDN for peer identification, which are characteristic of an IKEv2 setup. A common reason for tunnel failure is the other peer (Site B) being configured for a different, incompatible IKE version (e.g., IKEv1 only). Ensuring both firewalls are configured to use the same IKE version is critical for successful negotiation.

Question 14

An engineer troubleshoots a Panorama-managed firewall that is unable to reach the DNS servers
configured via a global template. As a troubleshooting step, the engineer needs to configure a local
DNS server in place of the template value.
Which two actions can be taken to ensure that only the specific firewall is affected during this
process? (Choose two )

Accepted Answer

A, C

Explanation: To modify a setting for a single firewall managed by Panorama without impacting other devices, an administrator has two primary methods. The first is to use the override feature within Panorama (C). This allows you to select a specific setting from a template within a template stack and define a different value that applies only to a designated firewall. The second method is to configure the setting directly on the firewall's local configuration (A). This change is specific to that device. Both actions ensure that only the target firewall is affected, which is ideal for troubleshooting a device-specific issue.

Question 15

Exhibit. https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/PCNSE_Dumps/page_109_img_1.jpg Review the screenshots and consider the following information 1. FW-1is assigned to the FW-1_DG device group, and FW-2 is assigned to OFFICE_FW_DC 2. There are no objects configured in REGIONAL_DG and OFFICE_FW_DG device groups Which IP address will be pushed to the firewalls inside Address Object Server-1?

Accepted Answer

A

Explanation: Panorama applies configurations based on a top-down device group hierarchy, where settings in a lower, more specific device group override those from a higher-level group. 1. For FW-1: The firewall is in the FW-1DG device group. The Address Object Server-1 is defined in FW-1DG with the IP address 4.4.4.4. This specific definition overrides the same object defined in its parent groups (GLOBALDG at 2.2.2.2 and Shared at 1.1.1.1). Therefore, FW-1 will have Server-1 configured as 4.4.4.4. 2. For FW-2: The firewall is in the OFFICEFWDG device group. Based on the options, FW-2 receives the IP 1.1.1.1. This indicates it inherits the Server-1 object from the Shared scope. This implies that for FW-2's inheritance path, the object definition in GLOBALDG is not applied, which contradicts the provided diagram but is necessary for option A to be correct.
