  2. Write-only access for offloading inserts
  3. No direct access; only the primary is reachable
  4. Read-only access, while the primary accepts reads and writes
Show the answer

Answer: D. Read-only access, while the primary accepts reads and writes

A read replica serves read queries only; the source becomes the primary and continues to take reads and writes.
