What is the purpose of Azure Bastion in an Azure Virtual Desktop setup?

Azure Bastion is a fully managed service that provides a secure and seamless RDP and SSH connectivity to your virtual machines directly in the Azure portal. When it comes to an Azure Virtual Desktop setup, its primary role is to secure administrative access to session hosts. By leveraging Azure Bastion, you can connect to your session hosts without exposing them to the public internet, thereby enhancing the security posture of your environment.

Azure Bastion helps to protect against potential attack vectors that can arise from having RDP or SSH ports open to the internet. Instead of requiring users to configure public IP addresses on their virtual machines, Azure Bastion establishes a secure connection through the Azure portal. This allows administrators and users to securely access the session hosts while maintaining a clean and hardened network configuration.

The other options do not align with the primary function of Azure Bastion. Providing antivirus configuration is not a feature of Azure Bastion; rather, traditional antivirus solutions would handle that. While Azure Bastion does facilitate secure connectivity, it does not enable VPN access, which is specifically tasked by Azure VPN Gateway. Lastly, automatically backing up virtual machines would typically be handled by Azure Backup, not Azure Bastion. Thus, securing administrative access to session hosts is the main purpose of Azure Bastion in
