Your team is planning to migrate a large on-premises data warehouse to BigQuery. You need to estimate the number of slots required to handle the expected query workload and stay within budget. What should you do?

Start with the default on-demand pricing and monitor usage for a month to see if you need a reservation.

Use the BigQuery pricing calculator to estimate costs based on the expected query volume and data size, and then create a reservation with the recommended number of slots.

Request a quota increase for BigQuery to ensure you can run as many queries as needed.

Create a reservation with the maximum number of slots available to ensure you never run out.
