You are the administrator of the ACME banking group. You want to deploy an application as code to Azure for testing. The only requirement is that this solution does not incur any costs while in testing mode. Which if of the following App Service Plan tiers will suffice and be the most cost-effective?
The F1 plan is correct, as this is the free version of the App service Plan, however, limited in functionality. D1,B1 and S1 tiers all will incur costs, even if they have more functionalities.
