Three equal-capacity zones each currently handle one third of application load. The application must sustain full load after one zone fails. Which design requirement follows?

Choose the single best answer.

A.Provision headroom so surviving zones can absorb the failed zone's load
B.Treat three-zone placement as sufficient capacity regardless of utilization
C.Place all application data on each VM's temporary disk
D.Use scale-set placement as automatic cross-region replication

Show the answer and explanation

✓ Correct answer

Provision headroom so surviving zones can absorb the failed zone's load

Zone placement must be combined with enough healthy surviving compute and dependency capacity. Three zones alone do not create headroom, temporary disks are not a replicated durable data design, and a regional scale set does not add cross-region replication. Source guide: PDF page(s) 45.
