Exam AZ-304 topic 5 question 1 discussion

Answer is B. To connect to Azure virtual machines using private IP address, we must do Virtual network integration. Virtual network integration is supported only on Azure Functions Dedicated plan and Azure Logics Apps ISE. Azure Functions dedicated plan is cheaper than Azure Logic Apps ISE. https://docs.microsoft.com/en-us/azure/azure-functions/functions-scale#hosting-plans-comparison

A is the correct answer, Consumption plan doesn't support vNet integration. ref: https://docs.microsoft.com/en-us/azure/azure-functions/functions-networking-options#matrix-of-networking-features

Option (D) Azure Functions in the Consumption plan may not have direct access to the private IP address, as it operates in a serverless environment with limited control over the underlying infrastructure. Therefore, option (B) Azure Functions in the Dedicated plan and the Basic Azure App Service plan is the most suitable choice for this scenario.

1. You don't need App service plan, because the C# code is in Azure Function 2. Azure function dedicated plan is more expensive than premium plan

There seems so much confusion over what looks like a simple question. Running custom C# so strongly points to a function over a logic app. I know you can call a function from a logic app but thats all exra cost, and the aim is minimising cost. B. Azure Functions in the Dedicated plan and the Basic Azure App Service plan Az function supports dedicated (but not consumption) plan supports virtual network integration: https://docs.microsoft.com/en-us/azure/azure-functions/functions-scale#networking-features Basic Azure App Service plan supports virtual network integration: https://docs.microsoft.com/en-us/azure/app-service/overview-vnet-integration Must be B surely

Answer should be D, because even though Consumption Plan does not support VNet integration, it does support Inbound IP restrictions ("...You can use access restrictions to define a priority-ordered list of IP addresses that are allowed or denied access to your app...") https://docs.microsoft.com/en-us/azure/azure-functions/functions-scale#networking-features https://docs.microsoft.com/en-us/azure/azure-functions/functions-networking-options?tabs=azure-cli#inbound-access-restrictions

A. Azure Logic Apps in the integrated service environment B. Azure Functions in the Dedicated plan and the Basic Azure App Service plan C. Azure Logic Apps in the Consumption plan D. Azure Functions in the Consumption plan I wish I could pick B, but the Basic App plan doesn't support vNet integration. Consumption plans (C and D) don't support vNet integration so the best chance of getting the answer right would be A I would say.

How can it be D? Per, https://docs.microsoft.com/en-us/azure/azure-functions/functions-scale Networking features section, virtual network integration isn't an option. Virtual network integration Virtual network integration allows your function app to access resources inside a virtual network. Azure Functions supports two kinds of virtual network integration: The dedicated compute pricing tiers, which include the Basic, Standard, Premium, Premium v2, and Premium v3. The App Service Environment, which deploys directly into your virtual network with dedicated supporting infrastructure and is using the Isolated and Isolated v2 pricing tiers.

Same question in 305 exam and option B is not even listed as an option!

Network support by function app comparison is here :- https://docs.microsoft.com/en-us/azure/azure-functions/functions-scale#networking-features

I vote A Azure Logic Apps in the integrated service environment

Not the best solutions to choose from but B and D are off due to lack of support for VNET integrations. That leaves only A - Logic App in ISE with a connector to some other part of the solution I suspect the wording of this question or the options are a bit bungled from what the actual questions on the exam may be.

https://docs.microsoft.com/en-us/azure/azure-functions/functions-networking-options

I go with a D https://docs.microsoft.com/en-us/azure/azure-functions/functions-networking-options private site access is Yes with a Consumption plan

A. Azure Logic Apps in the integrated service environment -Azure Logic Apps Standard plan provides connectivity to Vnet using an integration service environment B. Azure Functions in the Dedicated plan and the Basic Azure App Service plan Most Voted -Azure Functions in the Dedicated plan leverages Basic Azure App Service plan with no Vnet connectivity C. Azure Logic Apps in the Consumption plan -Azure Logic Apps Consumption plan provides no connectivity to Vnet D. Azure Functions in the Consumption plan -Azure Functions Consumption plan provides no connectivity to Vnet

Definitely D! Consumption plan is the most cost-effective, serveless plan available.

You can't do VNet integration on a basic plan.
