AZ-140 Azure Virtual Desktop Practice Exam 2025 – Complete Study Guide

Azure Bastion is a fully managed service that provides secure and seamless RDP and SSH connectivity to your Azure Virtual Desktop instances directly from the Azure portal. By using Azure Bastion, you eliminate the need to expose your virtual desktops to the public Internet, which significantly enhances security.

With Azure Bastion, users can access their virtual machines without needing a public IP address on the VM, reducing the attack surface. It operates over SSL, providing a secure browsing experience directly in the Azure portal. This service acts as an intermediary, allowing users to connect to their Azure Virtual Desktop environments securely, while mitigating the risks associated with remote access tools.

In contrast, while Azure Firewall and Azure Active Directory do offer security features, they are not specifically designed for the purpose of enabling secure remote desktop access to virtual environments like Azure Bastion. Azure Firewall is generally used to control traffic between Azure Virtual Network resources and protect against threats, while Azure Active Directory handles identity and access management. Azure Load Balancer is focused on distributing network traffic efficiently across multiple resources but does not address the secure connection requirement directly.
