Explanation: The two valid components that are used in installation of a VM-Series firewall in an OpenStack environment are: OpenStack heat template in YAML Ain't Markup Language (YAML) format VM-Series qcow2 image OpenStack is a cloud computing platform that provides infrastructure as a service (IaaS) for deploying and managing virtual machines (VMs) and other resources. OpenStack environment requires network security that can protect the traffic between VMs or other cloud services from cyberattacks and enforce granular security policies based on application, user, content, and threat information. VM-Series firewall is a virtualized version of the Palo Alto Networks next-generation firewall that can be deployed on various cloud or virtualization platforms, including OpenStack. OpenStack heat template in YAML format is a valid component that is used in installation of a VM-Series firewall in an OpenStack environment. OpenStack heat template is a file that defines the resources and configuration for deploying and managing a VM-Series firewall instance on OpenStack. YAML is a human-readable data serialization language that is commonly used for configuration files. YAML format is supported for OpenStack heat templates for VM-Series firewalls. VM-Series qcow2 image is a valid component that is used in installation of a VM- Series firewall in an OpenStack environment. VM-Series qcow2 image is a file that contains the software image of the VM-Series firewall for OpenStack. qcow2 is a disk image format that supports features such as compression, encryption, snapshots, and copy-on-write. qcow2 format is supported for VM-Series images for OpenStack. OpenStack heat template in JSON format and VM-Series VHD image are not valid components that are used in installation of a VM-Series firewall in an OpenStack environment, as those are not supported formats for OpenStack heat templates or VM-Series images.

Correct Answer: CD

Explanation: To deploy a VM-Series firewall on NSX, you need to enable communication between Panorama and the NSX Manager. This allows Panorama to receive information about the virtual machines and services in the NSX

environment. You also need to register the VM-Series firewall as a service on the NSX Manager. This allows NSX to redirect traffic to the VM-Series firewall for inspection3. References: VM-Series Deployment Guide for VMware NSX

Correct Answer: C

Explanation: DNS Security is the feature that provides real-time analysis using machine learning (ML) to defend against new and unknown threats. DNS Security leverages a cloud-based service that applies predictive analytics, advanced ML, and automation to block malicious domains and stop attacks in progress. Advanced URL Filtering (AURLF), Cortex Data Lake, and Panorama VM-Series plugin are not features that provide real-time analysis using ML, but they are related solutions that can enhance security and visibility.
