In the ingestion and history review, what is the retention policy applied to the lakehouse table mentioned?

• A. Indefinite
• B. One year
• C. Three months
• D. Six months

Answer: (D)

Retention policies for a lakehouse table control how long historical data and ingestion metadata are kept, enabling you to review past states and perform audits or recoveries. The six-month setting provides a practical window to inspect recent ingestions and data versions, supporting time travel and rollback if something goes wrong while keeping storage and maintenance costs reasonable. Longer retention (like indefinite or a full year) would incur more storage and governance overhead, and shorter periods (such as three months) might miss important earlier states. In this ingestion and history review context, six months strikes the right balance between accessibility to past data and efficient resource use.
