Managing retention policies is a typical use case for separate indexes because each index can have its own retention settings, allowing organizations to customize how long they keep different types of data. For example, high-volume log data might be retained for a shorter period due to storage constraints, while critical security logs could be kept for a longer duration to comply with regulatory requirements. This flexibility is essential for data management in environments where different data types have varying importance and legal obligations governing their retention.

While grouping similar types of data can be helpful, it serves more of an organizational purpose rather than addressing management-related needs like retention. Improving indexing speed typically involves optimizing configuration settings or hardware choices rather than separating data into different indexes. Lastly, the option that states "None of the above" indicates that there are appropriate use cases listed, which contradicts the validity of managing retention policies as a significant and practical usage of separate indexes.
