Practice question 481 of 506 · hard

A stateless Windows web service needs more VM instances during demand peaks and must tolerate loss of one supported Azure availability zone. Which two elements belong in the design? Select two answers.

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

A.One large VM in an availability set, with the assumption that Azure copies it to every zone
B.Instances distributed across supported availability zones, with application and traffic-routing dependencies designed for that failure
C.Place every scale-set instance in one availability zone and assume autoscale alone protects against loss of that zone
D.Configure vertical resizing of one VM and assume it supplies the requested additional running instances
E.A suitable VM scale set configuration with an autoscale policy and a tested application health path

Show the answer and explanation

✓ Correct answers

Instances distributed across supported availability zones, with application and traffic-routing dependencies designed for that failure
A suitable VM scale set configuration with an autoscale policy and a tested application health path

Autoscale provides additional instances, while supported multi-zone placement and resilient traffic/application dependencies address zone loss. An availability set does not clone a VM across zones. Vertical resizing does not supply horizontal instances, and autoscale within one failed zone does not establish zone resilience.
