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.

TSV files are typically used for data exchange between different applications, and are easily readable by humans.
