Which Azure service enables students to access virtual desktops from any device?

Azure Virtual Desktop (AVD) is the correct answer because it is a desktop and app virtualization service that runs on Azure. It allows users, such as students, to access virtualized desktops and applications from virtually anywhere, on any device, providing a consistent and secure experience. Azure Bastion is incorrect because it provides secure and seamless RDP/SSH connectivity to your virtual machines directly through the Azure portal over SSL, without requiring public IP addresses on your VMs. It's for secure VM access, not virtual desktops for end-users. Azure App Gateway is incorrect because it is a web traffic load balancer that enables you to manage traffic to your web applications. It's focused on application delivery, not virtual desktop infrastructure. Azure Functions is incorrect because it is a serverless compute service that enables you to run event-driven code without provisioning or managing infrastructure. It's for executing code, not providing virtual desktops.
