• Chose D1

  D. Planned maintenance is handled by update domains, not fault domains. Azure updates/reboots one update domain at a time, so if VM1 and VM2 are placed in different update domains, at least one VM stays available during planned maintenance. Fault domains protect against hardware/rack/power/network failure, not planned maintenance. One update domain would allow both VMs to be affected together during maintenance.

  Correct answer is still D. In case there is any confusion, update domains are for “planned”maintenance. https://docs.microsoft.com/en-us/azure/virtual-machines/windows/tutorial-availability-sets https://docs.microsoft.com/en-us/azure/virtual-machines/manage-availability https://docs.microsoft.com/en-us/azure/virtual-machines/maintenance-and-updates

  when hardware failure, fault domain need to use. If update such as windows update that require system reboot, update domain is use. So it should be fault tolerance I blv.
