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 network administrator needs to replace the default self-signed certificate on a firewall with one signed by the company's internal certificate authority (CA).
Which two firewall features would require this new certificate to be assigned via an SSL/TLS service profile? (Choose two.)
Which two zone types are valid when configuring a new security zone? (Choose two.)
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.)
Which two actions in the IKE Gateways will allow implementation of post-quantum cryptography when building VPNs between multiple Palo Alto Networks NGFWs? (Choose two.)
An engineer is creating an automation workflow. The first step is to deploy a new VM-Series firewall into a VMware vSphere environment, including its virtual machine (VM) configuration and network interfaces. The second step is to connect to the firewall and configure a complex set of Security policies and objects. The team uses both Terraform and Ansible.
For which part of this workflow would Terraform typically be used?
A network architect is planning the deployment of a new IPSec VPN tunnel to connect a local data center to a cloud environment. The plan must include all necessary Security policy configurations for both tunnel negotiation and data transit.
Which two Security policy requirements must be included in the implementation plan? (Choose two answers)
Palo Alto Networks NGFWs use SSL/TLS profiles to secure which two types of connections? (Choose two.)
What is the requirement for interface link speeds when configuring a virtual wire on a Palo Alto Networks firewall?
A network engineer has configured a PAN-OS firewall for client certificate authentication. The firewall has the corporate root CA certificate loaded. Client certificates are issued by an intermediate certificate authority (CA), which is signed by the root CA. However, when users attempt to connect, the authentication fails, and system logs indicate an "invalid certificate" error.
What is the most likely cause of this authentication failure?
An administrator configures a GlobalProtect gateway with split tunneling for network traffic based on an access route. Users report that public web browsing works, but they cannot resolve the names of internal servers. The administrator determines that all DNS queries are being sent to the public DNS servers configured on the users' endpoints.
Which GlobalProtect portal setting should be configured to resolve this issue?
After a recent security audit, a company is required to enforce more strict validation for all certificate-based authentication, including for GlobalProtect clients. An engineer observes the firewall accepting certificates from a recently compromised intermediate certificate authority (CA). The engineer needs to update the firewall configuration to use an Online Certificate Status Protocol (OCSP) responder to check for revoked certificates in real time.
In which configuration object would the engineer enable OCSP verification for the CAs used in the authentication process?
By default, which type of traffic is configured by service route configuration to use the management interface?
An engineer is configuring a GlobalProtect portal and wants to enable split tunneling. The requirement is to route DNS queries for "https://www.google.com/search?q=corp.internal.com" to the DNS servers assigned by the VPN, while allowing all other DNS queries to be resolved by the client's locally configured DNS.
What is the effect of configuring this split DNS policy?
When multiple routes have the same destination prefix, which attribute does the firewall use first to determine route preference?
An engineer is required to configure a site-to-site VPN that will automatically fail over to a backup link if the primary tunnel goes down. The engineer also needs to exchange routes dynamically between the sites.
Which two features necessitate assigning an IP address to the tunnel interface? (Choose two.)
Which statement describes the role of Terraform in deploying Palo Alto Networks NGFWs?
A network engineer observes a pattern of anomalous traffic hitting an external-facing zone, including a high volume of TCP packets that are not part of a new session handshake (non-SYN), and a large number of ICMP fragments. The engineer decides to apply a Zone Protection profile to mitigate these potential threats.
Which protection type within the profile must be configured?
An administrator is configuring a GlobalProtect pre-logon VPN. The administrator has already imported the necessary internal certificate authority (CA) certificates for issuing machine certificates onto the firewall.
Which configuration is required on the GlobalProtect Gateway to enable pre-logon using these machine certificates?
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.)
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 network administrator is establishing a site-to-site VPN between a Palo Alto Networks firewall and a partner's Check Point Security Gateway. The partner has provided a specific list of local and remote IP address subnets that are permitted through the tunnel. The initial tunnel configuration on the PAN-OS firewall fails during the IKE Phase 2 exchange.
Which configuration step is essential to ensure compatibility with the policy-based Check Point gateway?
An administrator needs to ensure that a firewall can download threat prevention and software updates, but the management port is on an isolated network without internet access.
Which service must be rerouted through a data plane interface using a service route to allow the firewall to download these updates?
When configuring a physical interface on a Palo Alto Networks firewall, which IP-based service is only available if the interface is set to Layer 3 mode?
A PA-Series firewall with all licensable features is being installed. The customer’s Security policy requires that users do not directly access websites. Instead, a security device must create the connection, and there must be authentication back to the Active Directory servers for all sessions.
Which action meets the requirements in this scenario?
An administrator enables SSL Forward Proxy decryption using a self-signed certificate on a Palo Alto Networks firewall as the forward trust certificate. Shortly after, users report receiving "Your connection is not private" browser errors for all external websites.
What is the most likely cause of these widespread certificate errors?
In an active/active high availability (HA) configuration with two PA-Series firewalls, how do the firewalls use the HA3 interface?
An administrator is configuring dynamic updates on a Palo Alto Networks firewall that protects a hospital's patient record system. The primary concern is ensuring maximum stability and avoiding any service disruption from a potentially problematic content update.
To align with Palo Alto Networks best practices for such environments, which threshold should the administrator set for content updates?
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?
What must be configured before a firewall administrator can define policy rules based on users and groups?
An engineer is troubleshooting a failed inter-VSYS communication path between a DMZ-VSYS and an Internal-VSYS. The configuration includes separate virtual routers with next-vr static routes and appropriate Security policies within each VSYS allowing traffic to and from their external zones.
Given that all routing and policy configurations within each individual VSYS are correct, what is the probable cause of the failure?
A Palo Alto Networks firewall has the following interfaces configured:
• ethernet1/1 (Layer 3)
• ethernet1/2 (TAP)
• ethernet1/3 (Layer 2)
• ethernet1/4 (virtual wire)
An administrator needs to create a link group to monitor upstream connectivity for high availability (HA) failover.
Which set of interfaces can be added to the link group?
Which networking technology can be configured on Layer 3 interfaces but not on Layer 2 interfaces?
Which zone type allows traffic between zones in different virtual systems (VSYS), without the traffic leaving the firewall?
In regard to the Advanced Routing Engine (ARE), what must be enabled first when configuring a logical router on a PAN-OS firewall?
Which forwarding methods can be used on the Objects tab when configuring the Log Forwarding profile?
