Select all that apply. Every correct option and no extras are required for credit in the app.

  1. A.Route requests to healthy workers using a suitable frontend and probes
  2. B.Treat additional worker count as a replacement for state durability
  3. C.Externalize or deliberately replicate state in a resilient service
  4. D.Assume the scale set automatically reconstructs every lost in-memory session
Show the answer and explanation

✓ Correct answers

  • Route requests to healthy workers using a suitable frontend and probes
  • Externalize or deliberately replicate state in a resilient service

Resilient state and healthy routing enable replacement workers to serve correctly. A scale set does not reconstruct arbitrary memory; extra stateless capacity alone does not retain sessions. Source guide: PDF page 40.
