What is the correct way to install different engines on the same Ubuntu machine for...

The XSOAR Engine Installation Guide explains that a single Linux host can run multiple engines using theShell Installer with the “Allow running multiple engines” option enabled. This method is specifically intended for Dev/Prod, HA, and multi-tenant scenarios. When this option is selected, the installer configures separate engine services and directories, preventing conflicts in ports, logs, or runtime environments.

Using Docker containers (option B) is not an officially supported or documented deployment method for running multiple XSOAR engines. Creating custom JSON or DEB installers (options A and D) applies to advanced engine deployments but doesnotenable multiple engines on the same host.

The Admin Guide explicitly states that the Shell Installer includes a built-in prompt allowing multiple engines to coexist safely, and this is the approved and supported mechanism provided by Palo Alto Networks. Therefore, the correct answer isC.
