Question #31
An organization has configured GlobalProtect in a hybrid authentication model using both certificate-based authentication for the pre-logon stage and SAML-based multi-factor authentication (MFA) for user logon.
How does the GlobalProtect agent process the authentication flow on Windows endpoints?
- A . The GlobalProtect agent uses the machine certificate to establish a pre-logon tunnel; upon user sign-in, it prompts for SAML-based MFA credentials, ensuring both device and user identities are validated before granting full access.
- B . The GlobalProtect agent uses the machine certificate during pre-logon for initial tunnel establishment, and then seamlessly reuses the same machine certificate for user-based
authentication without requiring MFA. - C . Once the machine certificate is validated at pre-logon, the Windows endpoint completes MFA on behalf of the user by passing existing Windows Credential Provider details to the GlobalProtect gateway without prompting the user.
- D . GlobalProtect requires the user to log in first for SAML-based MFA before establishing the pre-logon tunnel, rendering the pre-logon certificate authentication (CA) flow redundant.
Correct Answer: A
A
Explanation:
In a hybrid authentication model with both certificate-based authentication for pre-logon and SAML-based multi-factor authentication (MFA) for user logon, the GlobalProtect agent processes the flow as follows:
During the pre-logon stage, the agent uses the machine certificate to authenticate and establish the initial VPN tunnel.
Once the user logs in (after the machine is connected), the agent then triggers SAML-based MFA to ensure the user is authenticated with multi-factor authentication, validating both the device and the user identity before granting full access.
This method ensures that both the device and user are properly authenticated and validated in the hybrid authentication model.

Question #32
By default, which type of traffic is configured by service route configuration to use the management interface?
- A . Security zone
- B . IPSec tunnel
- C . Virtual system (VSYS)
- D . Autonomous Digital Experience Manager (ADEM)
Correct Answer: D
D
Explanation:
By default, the Autonomous Digital Experience Manager (ADEM) traffic is configured to use the management interface in a Palo Alto Networks firewall. The management interface is typically used for management-related traffic, such as monitoring and logging, and it is configured to handle ADEM-related traffic for the optimal performance of digital experience monitoring features.
This default configuration helps ensure that ADEM traffic does not interfere with regular traffic that may traverse other interfaces, such as traffic from security zones or IPSec tunnels.

Question #33
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 . 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.
- C . Configure a single certificate profile for both user and machine certificates. Rely solely on CRLs for revocation to minimize complexity.
- D . Deploy self-signed certificates on each firewall, allow IP-based authentication to override certificate checks, and use default GlobalProtect settings for user / machine identification.
Correct Answer: B
B
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.

Question #34
In an active/active high availability (HA) configuration with two PA-Series firewalls, how do the firewalls use the HA3 interface?
- A . To forward packets to the HA peer during session setup and asymmetric traffic flow
- B . To exchange hellos, heartbeats, HA state information, and management plane synchronization for routing and User-ID information
- C . To synchronize sessions, forwarding tables, IPSec security associations, and ARP tables between firewalls in an HA pair
- D . To perform session cache synchronization among all HA peers having the same cluster ID
Correct Answer: D
D
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.

Question #35
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 . Implementing Terraform templates for redundancy within one availability zone
- C . Using load balancer and health probes
- D . Configuring active/active HA
Correct Answer: C
C
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.

Question #36
Which networking technology can be configured on Layer 3 interfaces but not on Layer 2 interfaces?
- A . DDNS
- B . Link Duplex
- C . NetFlow
- D . LLDP
Correct Answer: C
C
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.

Question #37
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 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.
- 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 allow the firewall to bypass certificate validation entirely, focusing only on username / password-based authentication.
- D . They provide a one-click mechanism to distribute certificates to all endpoints without relying on external enrollment methods.
Correct Answer: B
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.

- A . Flood Protection
- B . Protocol Protection
- C . Packet-Based Attack Protection
- D . Reconnaissance Protection
Correct Answer: B
B
Explanation:
In the context of a Zone Protection profile, Protocol Protection is the section used to configure protections against activities such as spoofed IP addresses and split handshake session establishment attempts. These types of attacks typically involve manipulating protocol behaviors, such as IP address spoofing or session hijacking, and are mitigated by the Protocol Protection settings.

Question #39
Which PAN-OS method of mapping users to IP addresses is the most reliable?
- A . Port mapping
- B . GlobalProtect
- C . Syslog
- D . Server monitoring
Correct Answer: D
D
Explanation:
Server monitoring is the most reliable method for mapping users to IP addresses in PAN-OS. This method allows the firewall to monitor specific servers, such as Microsoft Active Directory (AD) or LDAP servers, to dynamically retrieve and update user-to-IP mappings. It provides a more accurate
and up-to-date mapping of users to their associated IP addresses, as it directly queries user databases in real time.

Question #40
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 . 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.
- B . 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.
- C . 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.
- 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.
Correct Answer: A
A
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.
