I would say answer is D which can insert message (upload message) https://docs.microsoft.com/en-us/azure/storage/queues/storage-dotnet-how-to-use-queues?tabs=dotnet#insert-a-message-into-a-queue which A can't https://docs.microsoft.com/en-us/cli/azure/storage/queue?view=azure-cli-latest

I think Azure CLI can change over time, and it's not a good practice to use commandline tools in an application.

So, it's safe to say you agree with the given answer, ".NET Core."

I think that should be A, because: - Azure CLI can be installed in Ubuntu: https://docs.microsoft.com/es-es/cli/azure/install-azure-cli-apt - Azure CLI supports upload messages to storage queues https://docs.microsoft.com/en-us/cli/azure/storage/message?view=azure-cli-latest - Azure CLI support create/delete queues https://docs.microsoft.com/en-us/cli/azure/storage/queue?view=azure-cli-latest - And of course, can be scheduled by CRON https://docs.microsoft.com/es-es/azure/batch/quick-create-cli

All of these are good, however, only .net is a developer friendly 'development' language. probably that's why it'll be D - .net core on Linux.

Is it really 'All of these are good' for developers? ADF and AzCopy also are dev tools now?)

ok, probably you are right but if this is the correct explanation this exam question borders on the ridiculous. IMHO of course

While Azure Cli does satisfy all requirements, the question is asking what DEVLOPERS should be using. Azure Cli is more like an Admin's tool. So D for NET Core.

Azure CLI is written in Python, it is also developer friendly and ideal for executing by a CRON job.

That CLI link is for a queue in a storage account, not a service bus. Dotnet Core is the answer (Core because it also runs on Linux). Create an executable which is run by the cron job.

Selected Answer: D

Developers should use .NET Core to interface with Azure Storage Queues. Using .NET Core, developers can write application code suitable for creating and deleting queues periodically, scheduling them on a CRON job schedule, and uploading messages every five minutes. Azure CLI is a command-line tool, AzCopy is a tool for data migration, and Azure Data Factory is a data integration service, none of these options are optimal for interacting with Azure Storage Queues. So, the answer is D - .NET Core.

Azure Cli and .NET core both work. But .NET core is recommended in this case, especially for the "every 5 minutes" requirement. No easy way to do it in Azure cli but very doable in .NET core.

Az CLI i is limited to provisioning and Data Factory can't be scheduloed by CRON. Anyway I think best option is to use .NET Core executable.

D, because Azure CLI is not "a processing solution", it is just a command line With .NET Core, you can develop a process to "upload messages every five minutes", which is not can be done by Azure CLI only.

Although Az CLI meets all the requirements, the best answer is .Net. After all a complete application with processing middle tier app makes more sense and since the devs are writing it, might as well be .net
