Question

You are developing an Azure Function App that processes images that are uploaded to an Azure Blob container. Images must be processed as quickly as possible after they are uploaded, and the solution must minimize latency. You create code to process images when the Function App is triggered. You need to configure the Function App. What should you do?

Options

  • AUse an App Service plan. Configure the Function App to use an Azure Blob Storage input trigger.
  • BUse a Consumption plan. Configure the Function App to use an Azure Blob Storage trigger.
  • CUse a Consumption plan. Configure the Function App to use a Timer trigger.
  • DUse an App Service plan. Configure the Function App to use an Azure Blob Storage trigger.
  • EUse a Consumption plan. Configure the Function App to use an Azure Blob Storage input trigger.
