Hi Nicholas,
Thank you for taking the time to analyze this scenario and for cross-checking it with Microsoft Learn.
You’re right to highlight the mismatch between the scenario’s requirements and the listed answer. In this case, the website is expected to experience a significant and unpredictable surge in global traffic following a marketing campaign. The key goals are:
-
Scaling dynamically based on traffic demand,
-
High availability and responsiveness, and
-
Minimal infrastructure management and cost efficiency.
While Azure App Service in the Standard plan supports autoscaling based on CPU utilization, it’s primarily suited for smaller or more predictable workloads. The Premium plan, however, offers:
-
Higher instance limits and faster scale-out for sudden global spikes,
-
Demand-based or automatic scaling with pre-warmed instances to minimize latency, and
-
A fully managed PaaS environment that removes the need for manual infrastructure management.
Therefore, the correct answer is Option 3 — Host the website on Azure App Service with the Premium plan and enable auto-scaling based on demand. This best satisfies the scenario’s requirements for performance, scalability, and reliability.
We appreciate you pointing this out, and we will update this item to reflect the correct answer.
