Which statement applies to a Cortex XSOAR engine that is part of a load-balancing group?

The correct choice indicates that a Cortex XSOAR engine that is part of a load-balancing group does not appear in the engine drop-down menu when configuring an integration instance. This is because engines that are part of a load-balancing group are designed to work together in that group context, which means they typically do not function as standalone entities in the integration setup. When configuring integration instances, the system only presents engines that can operate independently or are not currently part of a load-balancing configuration.

This design choice helps streamline the integration process, allowing administrators to select only applicable engines that can handle the specific tasks without the ambiguity of selecting an engine that is not operable individually. Understanding this principle is key to effectively managing and deploying engines in a load-balanced environment within Cortex XSOAR.
