AZ104-Q: App Service plan scaling
Q: Your App Service plan must scale out based on CPU usage automatically to a maximum of 6 instances. Which App Service plan tier is required?
- A) A tier that supports autoscale — Standard or higher ✓
- B) Free
- C) Shared
- D) Basic is enough for autoscale
Answer: A. Autoscale (scale-out based on CPU/queue etc.) requires the Standard, Premium, Isolated, or Elastic Premium plan. The Free and Shared tiers allow no autoscale/scale-out (Free/Shared are not SLA-backed, no dedicated instances, no autoscale). The exam anchors: autoscale needs Standard+.
Why it helps
Remember the App Service plan tier cutoff: Standard+ for autoscale & VNet integration; Free/Shared have no SLA and no autoscale.
