Where can you find the YAML files necessary for deploying the CN-Series firewall?

The correct answer is the GitHub repository because this location is a popular platform for hosting open-source projects and sharing code. For the CN-Series firewall, YAML files required for deployment are typically maintained in a GitHub repository. This allows users to access the latest versions, track updates, and collaborate on contributions, making it an ideal choice for sharing configuration files.

The other options, while they may contain valuable resources, do not explicitly focus on the latest deployment files. The Palo Alto Networks Customer Support Portal often provides assistance and downloads related to support but may not concentrate specifically on YAML files for the CN-Series firewall. Palo Alto Networks public documentation can offer detailed guides and references but may not serve as the direct source for downloading configuration files. The Marketplace generally features services and applications rather than specific deployment documentation or configuration scripts. Therefore, the GitHub repository stands out as the most appropriate source for YAML files necessary for deploying the CN-Series firewall.
