Question # 1

An organization's Security policy states that for all outbound web traffic, the TCP session to the external web server must be established by the firewall, not the user's workstation. This requires configuring user web browsers to point to the firewall. Authentication is also required.

Which solution on a PA-Series firewall meets these specific needs?

A.

Transparent proxy

B.

Explicit proxy

C.

GlobalProtect with User-ID

D.

Decryption policy with Authentication Portal

Question # 2

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.

Pushing threat intelligence updates to the new firewall

B.

Deploying the VM and associated network interfaces

C.

Storing the credentials needed to access the vSphere environment

D.

Applying the detailed Security policies and objects

Question # 3

A network security engineer wants to create Security policy rules that allow or deny traffic based on a user's department, which corresponds to groups in the company's Active Directory. To achieve this, the firewall needs to retrieve group information from the directory server.

Which configuration object must be created first to establish the connection with the Active Directory server?

A.

LDAP server profile

B.

User-ID agent service account

C.

Authentication sequence

D.

Kerberos server profile

Question # 4

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.

Question # 5

An NGFW engineer is configuring multiple Layer 2 interfaces on a Palo Alto Networks firewall, and all interfaces must be assigned to the same VLAN. During initial testing, it is reported that clients located behind the various interfaces cannot communicate with each other.

Which action taken by the engineer will resolve this issue?

A.

Configure each interface to belong to the same Layer 2 zone and enable IP routing between them.

B.

Assign each interface to the appropriate Layer 2 zone and configure a policy that allows traffic within the VLAN.

C.

Assign each interface to the appropriate Layer 2 zone and configure Security policies for interfaces not assigned to the same

zone.

D.

Enable IP routing between the interfaces and configure a Security policy to allow traffic between interfaces within the VLAN.

Question # 6

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?

A.

Define the local and remote subnets provided by the partner in the Proxy ID settings.

B.

Create individual Security policies for each pair of local and remote subnets.

C.

Assign a specific IP address to the tunnel interface to match the Check Point gateway.

D.

Enable Dead Peer Detection (DPD) in the IKE Gateway configuration.

Question # 7

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.

Question # 8

An organization is deploying VM-Series firewalls in Microsoft Azure to secure its VNets. A key requirement is that the security infrastructure must be resilient to the failure of an entire Azure Availability Zone.

What is the recommended method to achieve this goal?

A.

Deploy multiple, independent VM-Series firewalls in different Availability Zones and use an Azure Load Balancer to distribute traffic to them.

B.

Implement a Terraform configuration that automatically redeploys the firewall in a new zone if the original one fails.

C.

Use Azure Traffic Manager to direct traffic to a primary VM-Series firewall, with a second firewall in another zone as a failover target.

D.

Configure PAN-OS active/passive high availability (HA) between two VM-Series instances in separate Availability Zones using HA links over a VNet peering connection.

Question # 9

An administrator needs to perform several maintenance tasks on a managed firewall directly from the Panorama console, without using the Context Switch feature.

Which set of tasks can the administrator fully execute from the Panorama UI? (Choose one answer)

A.

Download and install a new content update. View current firewall session details. Initiate a device reboot.

B.

Create a new zone. Configure a new virtual router. View the local ACC on the firewall.

C.

Edit a post-rule. Create a new certificate profile. Configure the firewall's hostname.

D.

Modify the IP address of a Layer 3 interface. Configure a new local administrator account. Edit a pre-rule.

Question # 10

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?

A.

The decryption policy is configured with a "no-decrypt" action, which causes browsers to reject the connection.

B.

The external websites are using TLS 1.3, which cannot be decrypted by the firewall without a specific license.

C.

The firewall's forward untrust certificate has expired, preventing it from identifying untrusted sites.

D.

The firewall's self-signed CA certificate is not deployed to the trusted certificate store on client endpoints.
