A standard pooled pool uses external profiles and replaceable hosts. The team wants to deploy a tested monthly image while minimizing disruption. Which actions fit?

✓ Correct answers

• Drain old hosts and remove them only after the agreed session handling is complete.
• Create validated replacement hosts from the approved image with sufficient capacity before retiring old hosts.

For replaceable standard pooled hosts, use a controlled image-replacement pipeline with capacity, validation and user handling. Match servicing tools to the OS support matrix. Option explanations: A. Use Azure Update Manager as the supported Windows client multi-session patching method without checking the OS matrix.: The current AVD matrix does not support Azure Update Manager for this client OS. B. Drain old hosts and remove them only after the agreed session handling is complete.: Drain and controlled retirement reduce disruption; drain alone does not end sessions. C. Assume publishing the image silently patches every running host.: Image publication does not update existing VMs. D. Create validated replacement hosts from the approved image with sufficient capacity before retiring old hosts.: This maintains working capacity and tests the new compute before removing the old fleet.
