Which characteristic applies to Dynamic Data Active Archive (DDAA)?

The characteristic of Dynamic Data Active Archive (DDAA) that pertains to being purchased via accounts in 500 GB blocks is correct because DDAA is designed to provide scalable data archiving solutions. Organizations often need to manage large volumes of data, and having a plan that allows the purchase of storage in defined blocks facilitates budgeting and resource allocation. This model enables flexibility in scaling storage according to an organization’s data growth without needing to commit to a fixed amount of storage that may exceed their requirements.

The other characteristics do not accurately describe DDAA, as the service is not limited to permanent data storage; it is intended for data that may need to be accessed and utilized over time but is not necessarily kept permanently. Moreover, DDAA is not exclusively customer-managed—it often includes elements of management provided by the service to ensure compliance and efficiency in accessing archived data. Lastly, DDAA does not require on-premises infrastructure because it leverages cloud-based solutions to provide the necessary storage capabilities, allowing companies to avoid the complexities and costs associated with maintaining their own physical infrastructure.
