NEW QUESTION # 13
How does a Palo Alto Networks firewall choose the best route when it receives routes for the same destination from different routing protocols?
- A. It will attempt to load balance the traffic across all routes.
- B. It compares the administrative distance and chooses the one with the highest value.
- C. The route that was received first will be entered into the forwarding table, and all subsequent routes will be rejected.
- D. It compares the administrative distance and chooses the one with the lowest value.
Answer: D
Explanation:
When a Palo Alto Networks firewall receives routes for the same destination from different routing protocols, it uses the administrative distance (AD) to determine the best route. The administrative distance is a measure of the trustworthiness of a route, with a lower value indicating higher preference. The firewall will choose the route with the lowest administrative distance to populate its forwarding table.
NEW QUESTION # 14
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?
- A. Enable the "allow inter-VSYS traffic" option in both external zone configurations.
- B. Add each VSYS to the list of visible virtual systems of the other VSYS.
- C. Create a transit VSYS and route all inter-VSYS traffic through it.
- D. Create Security policies to allow the traffic between the two external zones.
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 # 15
In an active/active high availability (HA) configuration with two PA-Series firewalls, how do the firewalls use the HA3 interface?
- A. To exchange hellos, heartbeats, HA state information, and management plane synchronization for routing and User-ID information
- B. To perform session cache synchronization among all HA peers having the same cluster ID
- C. To synchronize sessions, forwarding tables, IPSec security associations, and ARP tables between firewalls in an HA pair
- D. To forward packets to the HA peer during session setup and asymmetric traffic flow
Answer: B
Explanation:
In an active/active HA configuration with two PA-Series firewalls, the HA3 interface is used primarily for the exchange of HA state information between the firewalls. This includes:
Hellos and heartbeats to monitor the status of the HA peer.
Synchronization of management plane data, which includes critical routing and User-ID information.
NEW QUESTION # 16
An enterprise uses GlobalProtect with both user- and machine-based certificate authentication and requires pre-logon, OCSP checks, and minimal user disruption. They manage multiple firewalls via Panorama and deploy domain-issued machine certificates via Group Policy.
Which approach ensures continuous, secure connectivity and consistent policy enforcement?
- A. Use a wildcard certificate from a public CA, disable all revocation checks to reduce latency, and manage certificate renewals manually on each firewall.
- B. Deploy self-signed certificates on each firewall, allow IP-based authentication to override certificate checks, and use default GlobalProtect settings for user / machine identification.
- C. Configure a single certificate profile for both user and machine certificates. Rely solely on CRLs for revocation to minimize complexity.
- D. Distribute root and intermediate CAs via Panorama template, use distinct certificate profiles for user versus machine certs, reference an internal OCSP responder, and automate certificate deployment with Group Policy.
Answer: D
Explanation:
To ensure continuous, secure connectivity and consistent policy enforcement with GlobalProtect in an enterprise environment that uses user- and machine-based certificate authentication, the approach should:
Distribute root and intermediate CAs via Panorama templates: This ensures that all firewalls managed by Panorama share the same trusted certificate authorities for consistency and security.
Use distinct certificate profiles for user vs. machine certificates: This enables separate handling of user and machine authentication, ensuring that both types of certificates are managed and validated appropriately.
Reference an internal OCSP responder: By integrating OCSP checks, the firewall can validate certificate revocation in real-time, meeting the security requirement while minimizing the overhead and latency associated with traditional CRLs (Certificate Revocation Lists).
Automate certificate deployment with Group Policy: This ensures that machine certificates are deployed in a consistent and scalable manner across the enterprise, reducing manual intervention and minimizing user disruption.
This approach supports the requirements for pre-logon, OCSP checks, and minimal user disruption, while maintaining a secure, automated, and consistent authentication process across all firewalls managed via Panorama.
NEW QUESTION # 17
Which set of options is available for detailed logs when building a custom report on a Palo Alto Networks NGFW?
- A. Threat, GlobalProtect, application statistics, WildFire submissions
- B. GlobalProtect, traffic, application statistics
- C. Traffic, User-ID, URL
- D. Traffic, threat, data filtering, User-ID
Answer: D
Explanation:
When building a custom report on a Palo Alto Networks NGFW, you can select detailed logs that provide specific insights into various aspects of firewall activity. The available options for detailed logs typically include:
Traffic logs: These provide information on the network traffic passing through the firewall.
Threat logs: These logs capture data related to identified security threats, such as malware or intrusion attempts.
Data filtering logs: These logs capture events related to data filtering policies, such as preventing the transfer of sensitive data.
User-ID logs: These logs associate user identities with the traffic and activities observed on the firewall, enabling user-based policy enforcement.
NEW QUESTION # 18
What is a result of enabling split tunneling in the GlobalProtect portal configuration with the "Both Network Traffic and DNS" option?
- A. It specifies which domains are resolved by the VPN-assigned DNS servers and which domains are resolved by the local DNS servers.
- B. lt allows devices on a local network to access blocked websites by changing which DNS server resolves certain domain names.
- C. It specifies when the secondary DNS server is used for resolution to allow access to specific domains that are not managed by the VPN.
- D. It allows users to access internal resources when connected locally and external resources when connected remotely using the same FQDN.
Answer: A
Explanation:
When split tunneling is enabled with the "Both Network Traffic and DNS" option in the GlobalProtect portal configuration, it allows the firewall to control which traffic is sent over the VPN tunnel and which is not. Specifically, it determines which domains are resolved by the VPN-assigned DNS servers (for domains requiring VPN access) and which are resolved by local DNS servers (for domains that can be accessed without the VPN tunnel).
NEW QUESTION # 19
An administrator plans to upgrade a pair of active/passive firewalls to a new PAN-OS release. The environment is highly sensitive, and downtime must be minimized.
What is the recommended upgrade process for minimal disruption in this high availability (HA) scenario?
- A. Push the new PAN-OS version simultaneously to both firewalls, having them upgrade and reboot in parallel. Rely on automated HA reconvergence to restore normal operations without manually failing over traffic.
- B. Isolate both firewalls from the production environment and upgrade them in a separate, offline setup. Reconnect them only after validating the new software version, resuming HA functionality once both units are fully upgraded and tested.
- C. Suspend the active firewall to trigger a failover to the passive firewall. With traffic now running on the former passive unit, upgrade the suspended (now passive) firewall and confirm proper operation. Then fail traffic back and upgrade the remaining firewall.
- D. Shut down the currently active firewall and upgrade it offline, allowing the passive firewall to handle all traffic. Once the active firewall finishes upgrading, bring it back online and rejoin the HA cluster. Finally, upgrade the passive firewall while the newly upgraded unit remains active.
Answer: C
Explanation:
In an active/passive HA setup, the recommended process for upgrading involves minimizing downtime and ensuring traffic continuity by using the failover process:
Suspend the active firewall: This triggers a failover to the passive unit, making it the active unit.
Upgrade the former passive (now active) unit: With traffic now running on the previously passive unit, upgrade the suspended unit while the active unit continues handling traffic.
Confirm proper operation: Once the upgrade is complete, verify that the upgraded unit is functioning properly.
Fail traffic back: Once the upgraded firewall is confirmed to be working, fail the traffic back to the original active unit and upgrade the remaining firewall.
NEW QUESTION # 20
Which interface types should be used to configure link monitoring for a high availability (HA) deployment on a Palo Alto Networks NGFW?
- A. HA, Virtual Wire, and Layer 2
- B. Tap, Virtual Wire, and Layer 3
- C. Virtual Wire, Layer 2, and Layer 3
- D. HA, Layer 2. and Layer 3
Answer: C
Explanation:
When configuring link monitoring for high availability (HA) on a Palo Alto Networks NGFW, the following interface types are supported:
Virtual Wire: Used when you have a transparent mode firewall deployment, where the firewall operates at Layer 2 to monitor traffic between two network segments.
Layer 2: Also used in transparent mode, where the firewall operates as a Layer 2 device and can be configured for link monitoring.
Layer 3: Used in routed mode, where the firewall is involved in routing traffic and can also be configured to monitor links.
NEW QUESTION # 21
An organization runs multiple Kubernetes clusters both on-premises and in public clouds (AWS, Azure, GCP). They want to deploy the Palo Alto Networks CN-Series NGFW to secure east-west traffic within each cluster, maintain consistent Security policies across all environments, and dynamically scale as containerized workloads spin up or down. They also plan to use a centralized Panorama instance for policy management and visibility.
Which approach meets these requirements?
- A. Install standalone CN-Series instances in each cluster with local configuration only. Export daily policy configuration snapshots to Panorama for recordkeeping, but do not unify policy enforcement.
- B. Use Kubernetes-native deployment tools (e.g., Helm) to deploy CN-Series in each cluster, ensuring local insertion into the service mesh or CNI. Manage all CN-Series firewalls centrally from Panorama, applying uniform Security policies across on-premises and cloud clusters.
- C. Deploy a single CN-Series firewall in the on-premises data center to process traffic for all clusters, connecting remote clusters via VPN or peering. Manage this single instance through Panorama.
- D. Configure the CN-Series only in public cloud clusters, and rely on Kubernetes Network Policies for on-premises cluster security. Synchronize partial policy information into Panorama manually as needed.
Answer: B
Explanation:
This approach meets all the requirements for securing east-west traffic within each Kubernetes cluster, maintaining consistent security policies across on-premises and cloud environments, and allowing for dynamic scaling of the CN-Series NGFWs as containerized workloads spin up or down. By using Kubernetes-native deployment tools (such as Helm), the CN-Series NGFWs can be deployed and scaled dynamically within each cluster. Local insertion into the service mesh or CNI ensures that the NGFW can inspect traffic at the appropriate points within the cluster.
Centralized management via Panorama ensures that security policies are uniform across both on-premises and cloud environments, providing visibility and control across all clusters.
NEW QUESTION # 22
An engineer at a managed services provider is updating an application that allows its customers to request firewall changes to also manage SD-WAN. The application will be able to make any approved changes directly to devices via API.
What is a requirement for the application to create SD-WAN interfaces?
- A. REST API's "sdwanInterfaceprofiles" parameter on a Panorama device
- B. REST API's "sdwanInterfaces" parameter on a firewall device
- C. XML API's "InterfaceProfiles/sdwan" parameter on a firewall device
- D. XML API's "sdwanprofiles/interfaces" parameter on a Panorama device
Answer: B
Explanation:
To create SD-WAN interfaces through an API, the correct approach is to use the REST API's "sdwanInterfaces" parameter on a firewall device. This parameter allows you to configure SD-WAN interfaces directly on the firewall devices via API, ensuring that the required interfaces are set up and managed for SD-WAN functionality.
NEW QUESTION # 23
Which two statements describe an external zone in the context of virtual systems (VSYS) on a Palo Alto Networks firewall? (Choose two.)
- A. It is associated with an interface within a VSYS of a firewall.
- B. It is not associated with an interface; it is associated with a VSYS itself.
- C. It is a security object associated with a specific virtual router of a VSYS.
- D. It is a security object associated with a specific VSYS.
Answer: A,D
Explanation:
In the context of virtual systems (VSYS) on a Palo Alto Networks firewall, the external zone is typically associated with specific interfaces within a VSYS. Zones are fundamental security objects used to define traffic flow between interfaces, and the external zone would be used for interfaces that connect to external networks.
An external zone is associated with an interface within a VSYS of the firewall. This ensures that traffic from specific interfaces can be classified as belonging to the external zone, allowing the firewall to apply appropriate security policies.
The external zone is indeed a security object that is specific to a given VSYS, as each VSYS can have its own set of zones that are isolated from others.
NEW QUESTION # 24
Which two statements apply to configuring required security rules when setting up an IPSec tunnel between a Palo Alto Networks firewall and a third- party gateway? (Choose two.)
- A. The IKE negotiation and IPSec/ESP packets are allowed by default via the intrazone default allow policy.
- B. For incoming and outgoing traffic through the tunnel, creating separate rules for each direction is optional.
- C. The IKE negotiation and IPSec/ESP packets are denied by default via the interzone default deny policy.
- D. For incoming and outgoing traffic through the tunnel, separate rules must be created for each direction.
Answer: C,D
Explanation:
Separate rules must be created for each direction: Palo Alto Networks firewalls enforce security policies based on traffic direction. To allow bidirectional communication through the IPSec tunnel, two separate rules are required - one for incoming and one for outgoing traffic.
IKE negotiation and IPSec/ESP packets are denied by default: Palo Alto Networks firewalls use an interzone default deny policy, meaning that unless an explicit policy allows IKE (UDP 500/4500) and ESP (protocol 50) traffic, the firewall will block these packets, preventing tunnel establishment. Therefore, administrators must create explicit rules permitting IKE and IPSec/ESP traffic to the firewall's external interface.
NEW QUESTION # 25
What is the purpose of assigning an Admin Role Profile to a user in a Palo Alto Networks NGFW?
- A. Allow access to all resources without restrictions.
- B. Enable multi-factor authentication (MFA) for administrator access.
- C. Restrict access to sensitive report data.
- D. Define granular permissions for management tasks.
Answer: D
Explanation:
Assigning an Admin Role Profile to a user in a Palo Alto Networks NGFW is used to define granular permissions for management tasks. This allows administrators to control what actions a user can perform on the firewall, such as configuration changes, monitoring, and logging. By assigning different admin roles, you can ensure that users have access only to the areas and tasks they need, enforcing the principle of least privilege.
NEW QUESTION # 26
In a Palo Alto Networks environment, GlobalProtect has been enabled using certificate-based authentication for both users and devices. To ensure proper validation of certificates, one or more certificate profiles are configured.
What function do certificate profiles serve in this context?
- A. They allow the firewall to bypass certificate validation entirely, focusing only on username / password-based authentication.
- B. They define trust anchors (root / intermediate Certificate Authorities (CAs)), specify revocation checks (CRL/OCSP), and map certificate attributes (e.g., CN) for user or device authentication.
- C. They provide a one-click mechanism to distribute certificates to all endpoints without relying on external enrollment methods.
- D. They store private keys for users and devices, effectively allowing the firewall to issue or reissue certificates if the primary Certificate Authority (CA) becomes unavailable, providing a built-in fallback CA to maintain continuous certificate issuance and authentication.
Answer: B
Explanation:
In the context of GlobalProtect with certificate-based authentication, certificate profiles are used to ensure proper validation of the certificates. They perform the following functions:
Define trust anchors, which are the root and intermediate Certificate Authorities (CAs) that the firewall trusts to authenticate certificates.
Specify revocation checks, such as CRL (Certificate Revocation List) and OCSP (Online Certificate Status Protocol), to ensure that the certificates being used have not been revoked.
Map certificate attributes, such as the Common Name (CN), which helps in authenticating users and devices based on their certificates.

NEW QUESTION # 28
Which configuration step is required when implementing a new self-signed root certificate authority (CA) certificate for SSL decryption on a Palo Alto Networks firewall?
- A. Disable all existing SSL decryption rules until the new certificate is fully propagated.
- B. Set the subordinate CA certificate as the default routing certificate for all network traffic.
- C. Import the new subordinate CA certificate into the trust stores of all client devices.
- D. Configure the subordinate CA to issue certificates with indefinite validity periods.
Answer: C
Explanation:
When implementing a new self-signed root certificate authority (CA) for SSL decryption on a Palo Alto Networks firewall, the subordinate CA certificate (which is generated by the firewall) must be imported into the trust stores of all client devices. This ensures that client devices trust the firewall as a valid certificate authority, enabling the firewall to decrypt and re-encrypt SSL traffic.
Importing the subordinate CA certificate into the client devices' trust stores is necessary for those devices to trust the new self-signed root CA and properly handle SSL decryption traffic.
NEW QUESTION # 29
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?
- A. Select the "Enable Cloud Logging" option in the Cloud Logging section under Device --> Setup --> Management in the appropriate templates.
- B. Select the "Enable Duplicate Logging" option in the Cloud Logging section under Device --> Setup --> Management in the appropriate templates.
- C. Enable the "Panorama/Cloud Logging" option in the Logging and Reporting Settings section under Device --> Setup --> Management in the appropriate templates.
- D. Modify all active Log Forwarding profiles to select the "Cloud Logging" option in each profile match list in the appropriate device groups.
Answer: A
Explanation:
To begin sending logs to Strata Logging Service while continuing to forward them to Panorama log collectors, the necessary configuration is to enable Cloud Logging. This option is configured in the Cloud Logging section under Device → Setup → Management in the appropriate templates. Once enabled, this ensures that logs are directed both to the Strata Logging Service (cloud) and to the Panorama log collectors.
NEW QUESTION # 30
What must be configured before a firewall administrator can define policy rules based on users and groups?
- A. User Mapping profile
- B. LDAP Server profile
- C. Authentication profile
- D. Group mapping settings
Answer: D
Explanation:
Before a firewall administrator can define policy rules based on users and groups, the Group Mapping settings must be configured. These settings enable the firewall to map users to their respective Active Directory (AD) groups. This mapping allows the firewall to use user and group information to create policy rules based on group membership.
NEW QUESTION # 31

PA-850 and PA-460 are within the PA-800 and PA-400 Series, which also support ARE
NEW QUESTION # 33
Which two zone types are valid when configuring a new security zone? (Choose two.)
- A. Internal
- B. Tunnel
- C. Intrazone
- D. Virtual Wire
Answer: B,D
Explanation:
When configuring a new security zone on a Palo Alto Networks firewall, the two valid zone types are:
Tunnel: A Tunnel zone is used for traffic that is associated with a VPN tunnel, such as IPSec tunnels. Traffic passing through a tunnel interface is classified into this zone.
Virtual Wire: A Virtual Wire zone is used when a firewall operates in transparent mode (also known as Layer 2 mode). In this configuration, the firewall can inspect traffic without modifying the IP address structure of the network.
