Practice question 122 of 400 · medium

A team scales an Azure SQL database and expects every active connection to remain uninterrupted. What should the application design include?

Choose the single best answer.

  1. A.No retries because online scaling guarantees every connection survives
  2. B.Treat every retry as a new order without idempotency
  3. C.Bounded reconnect/retry behavior for possible brief interruptions
  4. D.Unbounded immediate retries across all clients
Show the answer and explanation

✓ Correct answer

  • Bounded reconnect/retry behavior for possible brief interruptions

Online scaling can still cause reconnects/brief interruptions, so safe bounded retries are necessary. Unlimited synchronized retries can overload recovery. Repeating business effects without idempotency can create duplicates. Source guide: PDF page 24.
