Question No. 1

What does the number of required flex credits for a VM-Series firewall depend on?

Show Answer Hide Answer
Correct Answer: A

The number of required flex credits for a VM-Series firewall depends on vCPU allocation. Flex credits are a flexible licensing model that allows customers to purchase and consume software NGFWs as needed, without having to specify the platform or deployment model upfront. Customers can use flex credits to provision VM-Series firewalls on any supported cloud or virtualization platform. The number of required flex credits for a VM-Series firewall depends on vCPU allocation, which is the number of virtual CPUs assigned to the VM-Series firewall instance. The vCPU allocation determines the performance and capacity of the VM-Series firewall instance, such as throughput, sessions, policies, rules, and features. The number of required flex credits for a VM-Series firewall does not depend on IP address allocation, network interface allocation, or memory allocation, as those are not factors that affect the licensing cost or consumption of flex credits.

Question No. 2

When implementing active-active high availability (HA), which feature must be configured to allow the HA pair to share a single IP address that may be used as the network's gateway IP address?

Correct Answer: B

Question No. 3

Which two mechanisms could trigger a high availability (HA) failover event? (Choose two.)

Show Answer Hide Answer
Correct Answer: A, D

Heartbeat polling and link monitoring are two mechanisms that can trigger an HA failover event. Heartbeat polling is a method of verifying the health of the peer firewall by sending periodic heartbeat messages. If the heartbeat messages are not received within a specified interval, the firewall assumes that the peer is down and initiates a failover. Link monitoring is a method of verifying the connectivity of the interfaces on the firewall by sending link state packets. If the link state packets are not received on a specified number of interfaces, the firewall assumes that the network is down and initiates a failover. Ping monitoring and session polling are not HA mechanisms, but they are used for path monitoring and session synchronization respectively.

Question No. 4

Which two configuration options does Palo Alto Networks recommend for outbound high availability (HA) design in Amazon Web Services using a VM-Series firewall? (Choose two.)

Show Answer Hide Answer
Correct Answer: C, D

Palo Alto Networks recommends two configuration options for outbound high availability (HA) design in Amazon Web Services using a VM-Series firewall: transit gateway and Security VPC, and traditional active-passive HA. Transit gateway and Security VPC allows you to use a single transit gateway to route traffic between multiple VPCs and the internet, while using a Security VPC to host the VM-Series firewalls. Traditional active-passive HA allows you to use two VM-Series firewalls in an HA pair, where one firewall is active and handles all traffic, while the other firewall is passive and takes over in case of a failure. Reference: [VM-Series Deployment Guide for AWS Outbound VPC]


Question No. 5

Which protocol is used for communicating between VM-Series firewalls and a gateway load balancer in Amazon Web Services (AWS)?

Show Answer Hide Answer
Correct Answer: B

Geneve is the protocol used for communicating between VM-Series firewalls and a gateway load balancer in Amazon Web Services (AWS). A gateway load balancer is a type of network load balancer that distributes traffic across multiple virtual appliances, such as VM-Series firewalls, in AWS. Geneve is a tunneling protocol that encapsulates the original packet with an additional header that contains metadata about the source and destination endpoints, as well as other information. Geneve allows the gateway load balancer to preserve the original packet attributes and forward it to the appropriate VM-Series firewall for inspection and processing. VRLAN, GRE, and VMLAN are not protocols used for communicating between VM-Series firewalls and a gateway load balancer in AWS, but they are related concepts that can be used for other purposes.
