CDS Data Lifecycle Management Flashcards

What is the key difference between data archiving and data backup?

Answer: Backups support disaster recovery; archives support long-term retention and retrieval

Backups are designed for rapid restoration after failure, while archives preserve data for long-term retention, compliance, and occasional retrieval.

A data steward discovers that a dataset scheduled for deletion under the retention policy is subject to a legal hold. What is the correct action?

Answer: Suspend the retention schedule and preserve the data until the hold is lifted

Legal holds override standard retention schedules; data must be preserved intact until the legal hold is formally released.

Which concept describes the practice of minimizing the amount of data collected to only what is strictly necessary for a defined purpose?

Answer: Data minimization

Data minimization is a privacy-by-design principle that limits data collection to what is adequate, relevant, and necessary for the stated purpose.

In the context of data lifecycle management, what is 'information asset register' used for?

Answer: Cataloging data assets with their classification, owner, retention period, and disposal rules

An information asset register inventories all data assets with metadata about ownership, sensitivity, retention, and disposal, enabling lifecycle governance.

Which storage tier is most appropriate for data that is rarely accessed but must be retained for 7+ years for regulatory compliance?

Answer: Cold/archival storage (tape or deep archive)

Cold or archival storage tiers offer the lowest cost for infrequently accessed data retained solely for compliance over long periods.

What is the purpose of a 'data destruction certificate' in a data lifecycle program?

Answer: To provide auditable proof that data was disposed of in accordance with policy

A data destruction certificate documents the method, date, and scope of disposal, providing a compliance record that data was properly destroyed.
