Answer: B

Explanation:

Setting up Liberty server clusters

A Liberty can be configured into a server cluster for application high availability and scale.

The collectiveController-1.0 feature and its capabilities are available only in multiple-server products such as WebSphere® Application Server Liberty Network Deployment and WebSphere Application Server Liberty for z/OS. The feature is not available in single-server products such as WebSphere Application Server Liberty, WebSphere Application Server Liberty – Express, or WebSphere Application Server Liberty Core. If you have a multiple-server product installation, you can use its collectiveController-1.0 feature to work with collective members from single-server products.
