A team of developers at your company plans to deploy, and then remove (AZ-900)

Correct answer: B) Azure DevTest Labs.
Azure DevTest Labs is a service that helps developers and testers quickly create environments in Azure while minimizing waste and controlling costs. It is designed to enable teams to deploy and remove virtual machines efficiently, which aligns with the requirements in the scenario.

Here's why Azure DevTest Labs is the best recommendation:
Deployment and removal of VMs: Azure DevTest Labs simplifies the process of deploying and removing virtual machines by providing pre-configured VM images and templates. This helps minimize the administrative effort required to manage the 50 VMs each week.
Azure Resource Manager (ARM) templates: The scenario mentions that the virtual machines are configured using Azure Resource Manager templates, which is a key feature of Azure DevTest Labs. It allows you to create and manage VMs using ARM templates, further streamlining the deployment process.

The other options are not as suitable for this scenario:
A) Azure Reserved Virtual Machine (VM) Instances: This option is for reserving and pre-paying for virtual machines, which does not address the need for quickly deploying and removing VMs.
C) Azure virtual machine scale sets: This option is more suitable for scaling VMs automatically based on demand, rather than the manual deployment and removal of VMs required in this scenario.
D) Microsoft Managed Desktop: This is a service for managing end-user devices, not for deploying and removing virtual machines.
