NEW QUESTION # 14
What must be configured before a firewall administrator can define policy rules based on users and groups?
- A. Group mapping settings
- B. Authentication profile
- C. LDAP Server profile
- D. User Mapping profile
Answer: A
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 # 15
A large enterprise wants to implement certificate-based authentication for both users and devices, using an on-premises Microsoft Active Directory Certificate Services (AD CS) hierarchy as the primary certificate authority (CA). The enterprise also requires Online Certificate Status Protocol (OCSP) checks to ensure efficient revocation status updates and reduce the overhead on its NGFWs. The environment includes multiple Active Directory forests, Panorama management for several geographically dispersed firewalls, GlobalProtect portals and gateways needing distinct certificate profiles for users and devices, and strict Security policies demanding frequent revocation checks with minimal latency.
Which approach best addresses these requirements while maintaining consistent policy enforcement?
- A. Configure each firewall independently to trust the root and intermediate CA certificates. Rely only on manual CRL checks for certificate revocation, and import both user and device certificates directly into each firewall's local certificate store for authentication.
- B. Obtain wildcard certificates from a public CA for both user and device authentication, and configure firewalls to perform CRL polling at the default update interval. Manually install user certificates on endpoints and synchronize firewall certificate stores through frequent manual SSH updates to maintain consistency.
- C. Deploy self-signed certificates at each site to simplify local certificate validation and reduce dependencies on a centralized CA. Turn off certificate revocation checks for lower overhead, rely on IP-based rules for GlobalProtect authentication, and use a single certificate profile for both users and devices.
- D. Distribute the root and intermediate CA certificates via Panorama as shared objects to ensure all firewalls have a consistent trust chain. Configure OCSP responder profiles on each firewall to offload revocation checks to an internal OCSP server while keeping CRL checks as a fallback. Maintain separate certificate profiles for user and device authentication and use an automated enrollment method - such as Group Policy or SCEP - to deploy certificates to endpoints.
Answer: D
Explanation:
This approach best addresses the enterprise's requirements for certificate-based authentication, OCSP checks, and consistent policy enforcement:
Distributing the root and intermediate CA certificates via Panorama ensures that all firewalls in the enterprise are consistent in their trust chain and can validate certificates properly.
Configuring OCSP responder profiles on each firewall offloads the revocation checks to an internal OCSP server, which reduces the overhead on the firewalls and ensures fast, real-time certificate status checks.
Using CRL checks as a fallback ensures reliability in case the OCSP responder is unavailable.
Separate certificate profiles for users and devices ensure that the firewall can enforce different security policies based on the type of certificate (user vs. device).
Automated certificate enrollment methods such as Group Policy or SCEP streamline certificate distribution to endpoints, ensuring efficient management of certificates across geographically dispersed firewalls.
NEW QUESTION # 16
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. Configure the subordinate CA to issue certificates with indefinite validity periods.
- 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. Disable all existing SSL decryption rules until the new certificate is fully propagated.
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 # 17
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 "sdwanInterfaces" parameter on a firewall device
- B. XML API's "sdwanprofiles/interfaces" parameter on a Panorama device
- C. XML API's "InterfaceProfiles/sdwan" parameter on a firewall device
- D. REST API's "sdwanInterfaceprofiles" parameter on a Panorama device
Answer: A
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 # 18
Which CLI command is used to configure the management interface as a DHCP client?
- A. set deviceconfig management type dhcp-client
- B. set network dhcp interface management
- C. set deviceconfig system type dhcp-client
- D. set network dhcp type management-interface
Answer: A
Explanation:
To configure the management interface as a DHCP client on a Palo Alto Networks NGFW, the correct CLI command is set deviceconfig management type dhcp-client.
This command configures the management interface to obtain an IP address dynamically using DHCP.
NEW QUESTION # 19
Without performing a context switch, which set of operations can be performed that will affect the operation of a connected firewall on the Panorama GUI?
- A. Modification of post NAT rules, creation of new views on the local firewall ACC tab, creation of local custom reports
- B. Modification of local security rules, modification of a Layer 3 interface, modification of the firewall device hostname
- C. Modification of pre-security rules, modification of a virtual router, modification of an IKE Gateway Network Profile
- D. Restarting the local firewall, running a packet capture, accessing the firewall CLI
Answer: B
Explanation:
In Panorama, without performing a context switch, the administrator can perform local configuration tasks directly on the connected firewall. The following operations can be done:
Modification of local security rules: Security rules can be modified directly on the connected firewall from the Panorama GUI.
Modification of a Layer 3 interface: Changes to the Layer 3 interfaces on the connected firewall can be done from Panorama, without needing to switch to the firewall's local interface.
Modification of the firewall device hostname: The firewall's hostname can be changed via Panorama.
NEW QUESTION # 20
When deploying Palo Alto Networks NGFWs in a cloud service provider (CSP) environment, which method ensures high availability (HA) across multiple availability zones?
- A. Deploying Ansible scripts for zone-specific scaling
- B. Configuring active/active HA
- C. Implementing Terraform templates for redundancy within one availability zone
- D. Using load balancer and health probes
Answer: D
Explanation:
To ensure high availability (HA) across multiple availability zones (AZs) in a cloud service provider (CSP) environment, using a load balancer with health probes is a recommended method. This setup ensures that traffic can be directed to the healthy NGFW instances across multiple availability zones. If one NGFW instance or availability zone goes down, the load balancer can redirect traffic to the available instance(s) in other zones, providing redundancy and maintaining service availability.
NEW QUESTION # 21
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. 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.
- B. 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.
- C. 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.
- D. 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.
Answer: B
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 # 22
Which statement applies to the relationship between Panorama-pushed Security policy and local firewall Security policy?
- A. The order of policy evaluation can be configured differently in different device groups.
- B. Local firewall rules are evaluated after Panorama pre-rules and before Panorama post-rules.
- C. Panorama post-rules can be configured to be evaluated before local firewall policy for the purpose of troubleshooting.
- D. When a policy match is found in a local firewall policy, if any Panorama shared post-rule is configured, it will still be evaluated.
Answer: B
Explanation:
Local firewall rules are evaluated after Panorama pre-rules (those applied before the firewall's local policies) and before Panorama post-rules (those applied after the firewall's local policies). This ensures that the local firewall rules do not override the central Panorama policy and are only applied in the appropriate order within the policy evaluation sequence.
NEW QUESTION # 23
Which zone type allows traffic between zones in different virtual systems (VSYS), without the traffic leaving the firewall?
- A. Isolated
- B. Transient
- C. Internal
- D. External
Answer: B
Explanation:
The Transient zone type is used to allow traffic between zones in different virtual systems (VSYS) on a Palo Alto Networks firewall without the traffic leaving the firewall. It provides a way for virtual systems to communicate with each other by acting as a temporary or intermediary zone. Traffic can pass through the firewall between the virtual systems without requiring physical interfaces or leaving the device.
NEW QUESTION # 24
Which statement applies to Log Collector Groups?
- A. Log redundancy is available only if each Log Collector has the same amount of total disk storage.
- B. The maximum number of Log Collectors in a Log Collector Group is 18 plus two hot spares.
- C. Enabling redundancy increases the log processing traffic in a Collector Group by 50%.
- D. In any single Collector Group, all the Log Collectors must run on the same Panorama model.
Answer: B
Explanation:
The maximum number of Log Collectors that can be added to a Log Collector Group is 18 plus 2 hot spares, ensuring redundancy and availability in case of failure. This allows for a total of up to 20 Log Collectors in a group, providing sufficient scalability and reliability for log collection.
NEW QUESTION # 25
Palo Alto Networks NGFWs use SSL/TLS profiles to secure which two types of connections? (Choose two.)
- A. User Authentication
- B. GlobalProtect Gateways
- C. GlobalProtect Portal
- D. NAT tables
Answer: B,C
Explanation:
Palo Alto Networks Next-Generation Firewalls (NGFWs) use SSL/TLS profiles to secure connections for services such as GlobalProtect Gateways and GlobalProtect Portals. These profiles are used to manage the SSL/TLS encryption and decryption for secure communication between the firewall and clients (such as VPN clients for GlobalProtect). This helps ensure the confidentiality and integrity of the data during transmission.
NEW QUESTION # 26
Which type of firewall resource can be assigned when configuring a new firewall virtual system (VSYS)?
- A. Security profile limit
- B. Memory
- C. Sessions limit
- D. ICPU
Answer: C
Explanation:
When configuring a new firewall virtual system (VSYS) on a Palo Alto Networks firewall, one of the resources that can be assigned is the sessions limit. This setting allows the administrator to control the number of active sessions that can be handled by the VSYS, ensuring that each virtual system has an appropriate allocation of resources based on its needs.
NEW QUESTION # 27
Which networking technology can be configured on Layer 3 interfaces but not on Layer 2 interfaces?
- A. NetFlow
- B. LLDP
- C. DDNS
- D. Link Duplex
Answer: A
Explanation:
NetFlow is a Layer 3 (network layer) protocol that collects and monitors IP traffic flows. It is typically configured on Layer 3 interfaces because it relies on IP information for traffic flow analysis, which is not available on Layer 2 interfaces. Layer 2 interfaces handle frames within the local network, and they don't have IP-related details that NetFlow uses to generate traffic statistics.
NEW QUESTION # 28
Which type of firewall resource can be assigned when configuring a new firewall virtual system (VSYS)?
- A. Security profile limit
- B. Memory
- C. Sessions limit
- D. ICPU
Answer: C
Explanation:
When configuring a new firewall virtual system (VSYS) on a Palo Alto Networks firewall, one of the resources that can be assigned is the sessions limit. This setting allows the administrator to control the number of active sessions that can be handled by the VSYS, ensuring that each virtual system has an appropriate allocation of resources based on its needs.
NEW QUESTION # 29
After an engineer configures an IPSec tunnel with a Cisco ASA, the Palo Alto Networks firewall generates system messages reporting the tunnel is failing to establish.
Which of the following actions will resolve this issue?
- A. Validate the tunnel interface VLAN against the peer's configuration.
- B. Ensure that an active static or dynamic route exists for the VPN peer with next hop as the tunnel interface.
- C. Configure the Proxy IDs to match the Cisco ASA configuration.
- D. Check that IPSec is enabled in the management profile on the external interface.
Answer: C
Explanation:
The Proxy IDs (or Traffic Selectors) define the local and remote subnets that are allowed to communicate over the IPSec tunnel. If the Proxy IDs on the Palo Alto Networks firewall do not match the configuration on the Cisco ASA, the tunnel will fail to establish because the firewalls won't agree on which traffic to encrypt. Ensuring that the Proxy IDs match between the Palo Alto Networks firewall and the Cisco ASA will resolve the issue.
NEW QUESTION # 30
A multinational organization wants to use the Cloud Identity Engine (CIE) to aggregate identity data from multiple sources (on premises AD, Azure AD, Okta) while enforcing strict data isolation for different regional business units. Each region's firewalls, managed via Panorama, must only receive the user and group information relevant to that region. The organization aims to minimize administrative overhead while meeting data sovereignty requirements.
Which approach achieves this segmentation of identity data?
- A. Disable redistribution of identity data entirely. Instead, configure each regional firewall to pull user and group details directly from its local identity providers (IdPs).
- B. Create one CIE tenant, aggregate all identity data into a single view, and redistribute the full dataset to all firewalls. Rely on per-firewall Security policies to restrict access to out-of-scope user and group information.
- C. Establish separate CIE tenants for each business unit, integrating each tenant with the relevant identity sources. Redistribute user and group data from each tenant only to the region's firewalls, maintaining a strict one-to-one mapping of tenant to business unit.
- D. Deploy a single CIE tenant that collects all identity data, then configure segments within the tenant to filter and redistribute only the relevant user/group sets to each regional firewall group.
Answer: C
Explanation:
To meet the requirement of data isolation for different regional business units while minimizing administrative overhead, the best approach is to establish separate Cloud Identity Engine (CIE) tenants for each business unit. Each tenant would be integrated with the relevant identity sources (such as on-premises AD, Azure AD, and Okta) for that specific region. This ensures that the identity data for each region is kept isolated and only relevant user and group data is distributed to the respective regional firewalls.
By maintaining a strict one-to-one mapping between CIE tenants and business units, the organization ensures that each region's firewall only receives the user and group data relevant to that region, thus meeting data sovereignty requirements and minimizing administrative complexity.
NEW QUESTION # 31

- B. PA-5280, PA-7080, PA-3250, VM-Series
- C. PA-455, VM-Series, PA-1410, PA-5450
- D. PA-3260, PA-5410, PA-850, PA-460
Answer: D
Explanation:
The Advanced Routing Engine (ARE) is supported on Palo Alto Networks firewalls that utilize the PAN-OS 11.0+ software and have the required hardware architecture. The supported models include PA-3200 Series, PA-5400 Series, PA-800 Series, and PA-400 Series. These models provide enhanced routing capabilities, including BGP, OSPF, and more complex routing policies.
PA-3260 and PA-5410 are part of the PA-3200 and PA-5400 Series, which are known to support ARE.
PA-850 and PA-460 are within the PA-800 and PA-400 Series, which also support ARE
NEW QUESTION # 32
An engineer is implementing a new rollout of SAML for administrator authentication across a company's Palo Alto Networks NGFWs. User authentication on company firewalls is currently performed with RADIUS, which will remain available for six months, until it is decommissioned. The company wants both authentication types to be running in parallel during the transition to SAML.
Which two actions meet the criteria? (Choose two.)
- A. Create an authentication sequence that includes both the "RADIUS" Server Profile and "SAML Identity Provider" Server Profile to run the two services in tandem.
- B. Create a testing and rollback plan for the transition from Radius to SAML, as the two authentication profiles cannot be run in tandem.
- C. Create and add the "SAML Identity Provider" Server Profile to the authentication profile for the "RADIUS" Server Profile.
- D. Create and apply an authentication profile with the "SAML Identity Provider" Server Profile.
Answer: A,C
Explanation:
To enable both RADIUS and SAML authentication to run in parallel during the transition period, you need to configure an authentication sequence and an authentication profile that includes both authentication methods.
By creating an authentication sequence that includes both RADIUS and SAML server profiles, the firewall will attempt authentication with RADIUS first and, if that fails, will fall back to SAML. This enables both authentication types to function simultaneously during the transition period.
You can also configure an authentication profile that includes both the RADIUS Server Profile and the SAML Identity Provider server profile. This setup allows the firewall to use both RADIUS and SAML for authentication requests, and it will check both authentication methods in parallel.
