Exam AZ-301 topic 3 question 6 discussion

Answer A seems correct. Answer B is wrong - Why would you bind a function to SendGrid instead of Event Source i.e. IoT device.

I'm going with B: - functions are cheaper than logic apps (The first 400,000 GB/s of execution and 1,000,000 executions are free.) - you can easily create a cosmosdb trigger (https://docs.microsoft.com/en-us/azure/azure-functions/functions-create-cosmos-db-triggered-function)

Question is not properly described.

B. Deploy a function app that is configured to use the Consumption plan and a SendGrid binding.

B is correct answer.

B is correct. There is not such thing like SendGrid binding.

i will go with A

https://docs.microsoft.com/en-us/azure/cosmos-db/serverless-computing-database I think: B

Following Azure doc says Logic App is the right connector for Azure cosmos DB SQL APi https://docs.microsoft.com/en-us/connectors/documentdb/ Don't you guys think about option A? Thanks

There is no trigger for CosmosDB availabe in Logics Apps, so B is correct answer

The correct answer is B. You can send email by using SendGrid bindings in Azure Functions. Azure Functions supports an output binding for SendGrid. Note: When you're using the Consumption plan, instances of the Azure Functions host are dynamically added and removed based on the number of incoming events. Reference: https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-sendgrid https://docs.microsoft.com/en-us/azure/azure-functions/functions-scale#consumption-plan

Correct Answer: B. https://docs.microsoft.com/en-us/azure/azure-functions/functions-triggers-bindings

I'll go with B. Logic Apps Cosmos DB connector is for creating and updating documents, there's no cosmos DB trigger in Logic apps. But you can use a cosmos DB trigger in a function.

I think both Azure logic app and Azure function works well, https://docs.microsoft.com/en-us/azure/cosmos-db/serverless-computing-database#iot-use-case---azure-functions-trigger-and-output-binding-for-cosmos-db, https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-sendgrid?tabs=csharp, and Azure function & consumption plan should be cheaper, I will go with B.

i think key word here is sendgrid action and sendgrid binding

Isn't Logic app comes with hidden charges which requires polling? so functions app in consumption plan could be cheaper?
