Actual exam question from Microsoft's AZ-203

Question #: 17
Topic #: 2

You develop a website. You plan to host the website in Azure. You expect the website to experience high traffic volumes after it is published.
You must ensure that the website remains available and responsive while minimizing cost.
You need to deploy the website.
What should you do?

A. Deploy the website to a virtual machine. Configure the virtual machine to automatically scale when the CPU load is high.
B. Deploy the website to an App Service that uses the Shared service tier. Configure the App service plan to automatically scale when the CPU load is high.
C. Deploy the website to an App Service that uses the Standard service tier. Configure the App service plan to automatically scale when the CPU load is high.
D. Deploy the website to a virtual machine. Configure a Scale Set to increase the virtual machine instance count when the CPU load is high.

Show Suggested Answer

Suggested Answer: C 🗳️
Windows Azure Web Sites (WAWS) offers 3 modes: Standard, Free, and Shared.
Standard mode carries an enterprise-grade SLA (Service Level Agreement) of 99.9% monthly, even for sites with just one instance.
Standard mode runs on dedicated instances, making it different from the other ways to buy Windows Azure Web Sites.
Incorrect Answers:
B: Shared and Free modes do not offer the scaling flexibility of Standard, and they have some important limits.
Shared mode, just as the name states, also uses shared Compute resources, and also has a CPU limit. So, while neither Free nor Shared is likely to be the best choice for your production environment due to these limits.

given answer is correct, VM or shared service tier doesn't give availability.

VM also works but it's more expensive than app service, the question requires minimizing cost.

Is correct answer. C . Deploy the website to an App Service that uses the Standard service tier. Configure the App service plan to automatically scale when the CPU load is high.

Technically D would be also a valid solution, see https://docs.microsoft.com/en-us/azure/virtual-machine-scale-sets/overview On another side you would need a load balancer or an app gateway so it is not a complete response, but the statement is valid though. As usual, Exam questions are misleading ;).

Well the question is - what should you do ? Not which option would work. and having VM with load balancer is just too much
