After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You are migrating an on-premises application to Azure. One component of the application is a legacy Windows native executable that performs image processing.
The image processing application must run every hour. During times that the image processing application is not running, it should not be consuming any Azure compute resources.
You need to ensure that the image processing application runs correctly every hour.
Solution: Create an Azure Batch application that runs the image processing application every hour.
Does the solution meet the goal?

A. Yes
B. No

Answer is Yes. - Nodes can run any executable or script that is supported by the operating system environment of the node. Executables or scripts include *.exe, *.cmd, *.bat, and PowerShell scripts for Windows https://docs.microsoft.com/en-us/azure/batch/batch-api-basics#compute-node There is no charge for Batch itself, only the underlying compute and other resources consumed to run your batch jobs, including applicable software license costs. Virtual machines are billed per-second rounded down to the last minute. https://azure.microsoft.com/en-in/pricing/details/batch/

Azure Batch needs a seprate Scheduler which makes it dependent .. Azure Logic Apps is a complete solution..

The scheduler seems to be built in as seen here?: https://docs.microsoft.com/en-us/azure/batch/batch-job-schedule

answer should be yes as azure batch is not charging for compute resources when it is not processing and there they have not asked for minimum cost so there is no reason to compare with another solution azure function with consumption plan mentioned in another question.

From my research Logic apps can't run windows .exe Azure functions is best solution to me with its consumption plans and ability to run exe

the is answer is A When defining a pool in the Azure Batch account, you can scale the number of nodes based on an Auto scale formula.

Correct Answer: B. You're billed for every compute node in the pool, regardless of the state it's in. This includes any charges required for the node to run such as storage and networking costs. https://docs.microsoft.com/en-us/azure/batch/best-practices

I believe you need a minimum of 1 node in the batch pool, so you will be consuming compute resources

I think the right answer is Acute Functions with consumption plan. You can use auto scaling to decrease the number of nodes running when workouts is reduced using Acute Batch, however the will be always a minimum number of VMs running. There's no option to shut them all down between batch schedules then bring then up again. So there will be a compute cost.

this one again, you must use logic apps to schedule azure batch. you need both, not just 1

This is my opinion as well. But nobody else seems to be wondering about the native windows executable which I am pretty sure cannot be used within Azure Logic Apps...

Why isn't yes the correct answer? Azure batch would not consume any computer resources when not running. I am assuming batch does not have any issues in running legacy windows executables

Seems No, batch cost and VM cost, please refer https://azure.microsoft.com/en-in/pricing/details/batch/ Graphics and rendering application licensing Azure Batch pools can optionally be configured with graphics and rendering applications installed, where the application licensing is handled by Batch and the application costs are billed by Batch alongside the VM costs. As with the VM costs, the applications are charged per minute for the lifetime of each VM. See the Azure Batch documentation for more information on rendering using Azure Batch.

There’s no charge for Batch itself, only the underlying compute and other resources consumed to run your batch jobs. If Job complete, the VM will be released and no ongoing cost
