Which approach supports heavy analytical scans over operational data without consuming transactional RU/s?

  1. A Increase autoscale maximum
  2. B Enable analytical store and query it with Azure Synapse Link (correct answer)
  3. C Add more read regions
  4. D Use Direct mode connectivity

Shortcut: Analytical store keeps a column-oriented copy updated automatically and is queried through Synapse Link. It is billed separately and does not draw on transactional RU/s.
