Which option is commonly purchased for medium to long-term retention in Splunk Cloud?

The option commonly purchased for medium to long-term retention in Splunk Cloud is the Dynamic Data Active Archive. This storage solution is specifically designed to manage large volumes of data that do not require frequent access but need to be retained for a longer duration due to compliance, auditing, or analytical purposes.

Dynamic Data Active Archive enables organizations to efficiently store data while optimizing costs, as it leverages cloud-based storage capabilities that can scale according to the needs of the business. This feature allows the data to be accessed more easily compared to static archives, thus providing a balance between retention, accessibility, and cost-efficiency.

In contrast, the Static Data Archive is primarily used for data that is infrequently accessed and intended for long-term storage without the intention of regular retrieval, making it less ideal for medium to long-term use cases that might still require some level of accessibility. Dynamic Data Self Storage is typically not associated with long-term retention but focuses more on user-managed storage solutions. Basic Index Storage is more related to active indexing rather than archival, making it unsuitable for long-term retention needs.
