Demo Questions

Question 1
A network security engineer is segmenting a single firewall into VSYS-A and VSYS-B. For traffic to flow from VSYS-A to VSYS-B, external zones are required.
What are two fundamental properties of the external zones needed for this configuration? (Choose two.)
  1. They must be linked to the same virtual router as the ingress interface.
  2. They represent their parent VSYS without being tied to a physical or logical interface.
  3. They are a security construct belonging to a single VSYS.
  4. They are automatically created when inter-VSYS routing is enabled.
Correct answer: B, C
Question 2
A firewall administrator needs to configure a new Palo Alto Networks firewall so that its management interface automatically obtains an IP address, netmask, and default gateway from the network.
Which command should be executed in the CLI to accomplish this goal?
  1. set deviceconfig system interface mgt mode dhcp
  2. set network interface management dhcp enable
  3. set deviceconfig system type dhcp-client
  4. configure system management-interface ip dynamic
Correct answer: A
Question 3
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.)
  1. User-ID agent redistribution
  2. RADIUS server authentication
  3. Authentication portal
  4. GlobalProtect gateway
Correct answer: A, C
Question 4
When deploying Palo Alto Networks NGFWs in a cloud service provider (CSP) environment, which method ensures high availability (HA) across multiple availability zones?
  1. Deploying Ansible scripts for zone-specific scaling
  2. Implementing Terraform templates for redundancy within one availability zone
  3. Using load balancer and health probes
  4. Configuring active/active HA
Correct answer: C
Question 5
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?
  1. REST API’s “sdwanInterfaceprofiles” parameter on a Panorama device
  2. REST API’s “sdwanInterfaces” parameter on a firewall device
  3. XML API’s “sdwanprofiles/interfaces” parameter on a Panorama device
  4. XML API’s “InterfaceProfiles/sdwan” parameter on a firewall device
Correct answer: B
Question 6
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?
  1. Import the new subordinate CA certificate into the trust stores of all client devices.
  2. Set the subordinate CA certificate as the default routing certificate for all network traffic.
  3. Configure the subordinate CA to issue certificates with indefinite validity periods.
  4. Disable all existing SSL decryption rules until the new certificate is fully propagated.
Correct answer: A
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?
  1. 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.
  2. 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.
  3. 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.
  4. 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
Question 8
Which interface types should be used to configure link monitoring for a high availability (HA) deployment on a Palo Alto Networks NGFW?
  1. HA, Virtual Wire, and Layer 2
  2. Tap, Virtual Wire, and Layer 3
  3. Virtual Wire, Layer 2, and Layer 3
  4. HA, Layer 2, and Layer 3
Correct answer: C
Question 9
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?
  1. Ensure that an active static or dynamic route exists for the VPN peer with next hop as the tunnel interface.
  2. Configure the Proxy IDs to match the Cisco ASA configuration.
  3. Check that IPSec is enabled in the management profile on the external interface.
  4. Validate the tunnel interface VLAN against the peer’s configuration.
Correct answer: B
Question 10
Which statement applies to the relationship between Panorama-pushed Security policy and local firewall Security policy?
  1. When a policy match is found in a local firewall policy, if any Panorama shared post-rule is configured, it will still be evaluated.
  2. Local firewall rules are evaluated after Panorama pre-rules and before Panorama post-rules.
  3. Panorama post-rules can be configured to be evaluated before local firewall policy for the purpose of troubleshooting.
  4. The order of policy evaluation can be configured differently in different device groups.
Correct answer: B
