What can software next-generation firewall (NGFW) credits be used to provision?

  1. Remote browser isolation
  2. Virtual Panorama appliances
  3. Migrating NGFWs from hardware to VMs
  4. Enablement of DNS security

Answer(s): C

Explanation:

Software next-generation firewall (NGFW) credits can be used to provision migrating NGFWs from hardware to VMs. Software NGFW 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 software NGFW credits to migrate their existing hardware NGFWs to VM-Series firewalls on any supported cloud or virtualization platform, or to deploy new VM-Series firewalls as their needs grow. Software NGFW credits cannot be used to provision remote browser isolation, virtual Panorama appliances, or enablement of DNS security, as those are separate solutions that require different licenses or subscriptions.

How is traffic directed to a Palo Alto Networks firewall integrated with Cisco ACI?

  1. By using contracts between endpoint groups that send traffic to the firewall using a shared policy
  2. Through a virtual machine (VM) monitor domain
  3. Through a policy-based redirect
  4. By creating an access policy

Answer(s): C

Explanation:

Traffic is directed to a Palo Alto Networks firewall integrated with Cisco ACI through a policy-based redirect. Cisco ACI is a software-defined network (SDN) solution that provides network automation, orchestration, and visibility. A policy-based redirect is a mechanism that allows Cisco ACI to redirect traffic from one endpoint group (EPG) to another EPG through a service device, such as a Palo Alto Networks firewall. The firewall can then inspect and enforce security policies on the redirected traffic before sending it back to Cisco ACI. Traffic is not directed to a Palo Alto Networks firewall integrated with Cisco ACI by using contracts between endpoint groups that send traffic to the firewall using a shared policy, through a virtual machine (VM) monitor domain, or by creating an access policy, as those are not valid methods for traffic redirection in Cisco ACI.

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

  1. VRLAN
  2. Geneve
  3. GRE
  4. VMLAN

Answer(s): B

Explanation:

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.

Which two elements of the Palo Alto Networks platform architecture enable security orchestration in a software-defined network (SDN)? (Choose two.)

  1. Full set of APIs enabling programmatic control of policy and configuration
  2. VXLAN support for network-layer abstraction
  3. Dynamic Address Groups to adapt Security policies dynamically
  4. NVGRE support for advanced VLAN integration

Answer(s): A,C

Explanation:

The two elements of the Palo Alto Networks platform architecture that enable security orchestration in a software-defined network (SDN) are:
Full set of APIs enabling programmatic control of policy and configuration

Dynamic Address Groups to adapt Security policies dynamically The Palo Alto Networks platform architecture consists of four key elements: natively integrated security technologies, full set of APIs, cloud-delivered services, and centralized management. The full set of APIs enables programmatic control of policy and configuration across the platform, allowing for automation and integration with SDN controllers and orchestration tools. Dynamic Address Groups are objects that represent groups of IP addresses based on criteria such as tags, regions, interfaces, or user-defined attributes. Dynamic Address Groups allow Security policies to adapt dynamically to changes in the network topology or workload characteristics without requiring manual updates. VXLAN support for network-layer abstraction and NVGRE support for advanced VLAN integration are not elements of the Palo Alto Networks platform architecture, but they are features that support SDN deployments.
