A fintech app added features that required a new topic in an existing Amazon MSK cluster. A few days later, CloudWatch alarmed on the cluster's RootDiskUsed metric. How should the company respond to that CloudWatch alarm?

Correct answer: Increase the MSK broker storage and configure the MSK cluster to expand storage automatically..
Why this is the answer
The CloudWatch alarm on RootDiskUsed indicates the MSK broker's storage is nearing capacity. Adding a new topic increases data storage requirements, directly impacting the broker's disk space. Increasing MSK broker storage directly addresses this issue. Configuring automatic storage expansion prevents future alarms by allowing the cluster to scale storage dynamically as data grows. Increasing ZooKeeper storage is incorrect because ZooKeeper stores metadata, not message data, and wouldn't alleviate broker disk pressure. Upgrading the instance type primarily increases CPU and memory, not storage, unless a larger instance type also comes with proportionally more local storage, which isn't the primary solution for a RootDiskUsed alarm. Setting a "Target Volume-in-GiB parameter" for a topic is not a standard MSK configuration option for managing storage.
