CAS can support multiple backup controllers in a distributed architecture, which can improve performance and provide redundancy. Additionally, a backup controller can be added after the initial deployment, which can be useful for managing a large number of CAS workers.

It is false statement because CAS supports adding more than one backup controller in a CAS server architecture. The CAS Backup Controller is a separate process that runs alongside the CAS Controller and monitors the health of the CAS processes. It can be deployed on a separate machine or on the same machine as a CAS worker. The backup controller can be added during the initial deployment or after the initial deployment.

A CAS Backup controller is used in a distributed CAS server architecture but it can also be used in a single machine architecture too. CAS Backup controller provides an additional level of redundancy, in case the primary CAS controller goes down, it can take over its responsibilities.
