What action should be taken to access the data stored in cold buckets?

Data in cold buckets is read-only. In Splunk, cold buckets are part of the overall storage architecture, where older data that is accessed less frequently is stored to optimize performance and utilize storage resources efficiently. Once data is moved to cold buckets, it is considered archived and cannot be modified or deleted directly through standard Splunk search commands.

Accessing data from cold buckets is primarily done through read operations, allowing users to perform searches and retrieve useful insights from historical data while ensuring data integrity. This is a common practice in data management systems as it preserves the original data structure and content over time.

The other options suggest various levels of access and modifications that do not align with how cold buckets function within Splunk's data lifecycle. Understanding this read-only characteristic is essential for managing and querying historical data effectively.
