Next VR can be used as an Action when creating a Policy-Based Forwarding (PBF) policy. A PBF policy allows the firewall to forward traffic based on criteria such as source and destination IP addresses, application, user, and service. The Action of a PBF policy defines how the firewall forwards the matching traffic. Next VR specifies the virtual router to which the firewall forwards the traffic. Option A is incorrect because Deny is not a valid Action for a PBF policy. Deny is an Action for a security policy that blocks the matching traffic. Option B is incorrect because Discard is not a valid Action for a PBF policy. Discard is an Action for a DoS protection policy that drops the matching traffic. Option C is incorrect because Allow is not a valid Action for a PBF policy. Allow is an Action for a security policy that permits the matching traffic.

The heartbeat interval determines the frequency at which the HA peers exchange messages in the form of an ICMP (ping). The default value is 1000 milliseconds (1 second). The heartbeat interval is used to detect failures and trigger failover in an HA pair1. The other options are not correct. The hello interval determines the frequency at which the HA peers exchange messages in the form of an HA packet. The default value is 3000 milliseconds (3 seconds). The hello interval is used to establish and maintain HA connectivity2. The promotion hold time determines the amount of time that a passive firewall waits before it becomes active after detecting a failure on the active firewall. The default value is 5000 milliseconds (5 seconds)3. The monitor fail hold up time determines the amount of time that a firewall waits before it declares a monitor failure after detecting a link down event on an interface. The default value is 2000 milliseconds (2 seconds)4. Reference: 1:

Panorama offers three options for deploying dynamic updates to its managed devices: Schedules, Install from file, and Revert content. Schedules allows the administrator to configure a recurring schedule for downloading and installing dynamic updates from the Palo Alto Networks update server. Install from file allows the administrator to manually upload and install a dynamic update file from a local system. Revert content allows the administrator to revert to a previous version of a dynamic update in case of any issues with the current version. Option A is incorrect because Verify is not an option for deploying dynamic updates on Panoram a. Verify is an option for validating the configuration on Panorama or a managed device. Option D is incorrect because Check dependencies is not an option for deploying dynamic updates on Panorama. Check dependencies is an option for checking if a configuration change affects other settings on Panorama or a managed device.

The engineer can use the test vpn gateway CLI command to manually initiate a VPN tunnel from the CLI. This command allows the engineer to specify the name of the VPN gateway and the IP address of the peer to initiate an IKE negotiation and establish a VPN tunnel. Option A is incorrect because test vpn flow is not a valid CLI command. Option B is incorrect because test vpn ike-sa is a CLI command that displays information about the IKE security associations, not initiates a VPN tunnel. Option C is incorrect because test vpn tunnel is a CLI command that displays information about the IPSec security associations, not initiates a VPN tunnel.

Logging at session start should be used as a best practice while troubleshooting. Logging at session start allows the administrator to see the logs for sessions that are initiated but not completed, such as sessions that are dropped or blocked by the firewall. This can help the administrator to identify and resolve issues with network connectivity or firewall configuration. Logging at session start should not be used for normal operations because it generates more logs and consumes more resources on the firewall. Option A is incorrect because logging at session start should not be used on all Allow rules. Logging at session end is sufficient for Allow rules because it provides information about the completed sessions, such as bytes and packets transferred, application, user, and threat information.

Option C is incorrect because logging at session start can be used independently of logging at session end. Logging at session start and logging at session end are not mutually exclusive options. Option D is incorrect because logging at session start should not be used only on Deny rules. Logging at session end is sufficient for Deny rules because it provides information about the denied sessions, such as source and destination IP addresses, ports, and protocol.

When overriding the firewall configuration pushed from Panorama, the modification will not be visible in Panoram a. The firewall will show an override icon next to the modified setting and will display a warning message that the local configuration differs from Panorama. The override icon will also appear on Panorama next to the firewall name in the Device Groups and Templates tabs1. The other options are not correct. The firewall template will not show that it is out of sync within Panorama, because the template itself is not modified. Panorama will not update the template with the overridden value, because the template is read-only on the firewall. The override can be reverted either from Panorama or from the firewall2.

An external zone is a type of zone that will allow different virtual systems to communicate with each other. An external zone is a special zone that is shared by all virtual systems on the firewall and can be used to route traffic between virtual systems without leaving the firewall. The external zone can also be used to route traffic to other zones within the same virtual system1. The other options are not correct. A tap zone is a type of zone that is used to passively monitor traffic without affecting the flow of packets2. A virtual wire zone is a type of zone that is used to create a transparent bridge between two network segments without changing the original IP addressing or routing3. A tunnel zone is a type of zone that is used to terminate VPN tunnels or other types of encapsulated traffic4.

Depending on the type of log you want to use for tagging, create a log forwarding profile or configure the log settings to define how you want the firewall or Panorama to handle logs. For Authentication, Data, Threat, Traffic, Tunnel Inspection, URL, and WildFire logs, create a log forwarding profile. For User-ID, GlobalProtect, and IP-Tag logs, configure the log settings.

The System Resources widget on the Dashboard in the WebUI shows both the management plane and data plane CPU utilization as well as other system resources such as memory, disk, and session1.

The other options do not show both the management plane and data plane CPU utilization. The Application Command and Control Center (ACC) shows the network activity and application usage based on traffic logs2. The Monitor >

Utilization page shows the interface utilization and packet buffer utilization3. The Support > Resources page shows the system resources for Panorama only4.
