A VM application must tolerate a full availability-zone outage within one region. Which starting architecture directly addresses that fault boundary?

Choose the single best answer.

A.Supported instances across zones with healthy routing, resilient state, and surviving capacity
B.One zonal VM with three redundant disks and no application replica
C.A region-pair selection assumed to deploy redundant workers automatically
D.Two VMs in one availability set assumed to span separate regions

Show the answer and explanation

✓ Correct answer

Supported instances across zones with healthy routing, resilient state, and surviving capacity

Deliberate zone spread and end-to-end dependencies address a zone failure. Sets distribute local fault/update domains rather than supplying a regional/zone-spanning application guarantee. Disk copies do not supply a replacement worker, and pairing deploys no app topology. Source guide: PDF page 40.
