Which of the following is not backed up in a managed cluster?

1. Configuration files

2. Cassandra

3. Transaction storage

4. Elastic Search

The correct answer is: Transaction storage

Transaction storage is not backed up in a managed cluster because it is specifically designed for high performance and low-latency access to transactional data. Managed clusters focus on managing the configuration and providing high availability, but they do not include transaction storage in their backup processes. This is due to the nature of the data handled and the need for real-time processing, which can be adversely impacted by typical backup operations. Other components, such as configuration files, Cassandra, and Elastic Search, are backed up because they contain settings and data relevant for system restoration and compliance, ensuring that the environment can be rebuilt or recovered in case of failure or data loss. These components play a critical role in the overall functionality and resilience of the managed cluster, while transaction storage emphasizes swift access and processing over redundancy in the backup strategy.
