A distributed development team at AlpineApps wants to replace jump boxes with Azure Bastion Standard. Their requirements: support for multiple concurrent sessions, scale to handle up to 50 simultaneous RDP/SSH sessions, allow connecting from known developer laptop public IPs, and provide shareable session links for contractors without exposing VM public IPs. How should they configure Azure Bastion Standard and related settings?

The correct option meets all requirements. Azure Bastion Standard supports multiple concurrent sessions and scaling up to 50 hosts (scale units). The 'Allowed IP Addresses' feature directly restricts access to specified public IPs, fulfilling the developer access requirement. The 'Shareable Bastion Connect' feature is designed for generating time-limited, shareable links for external users like contractors without exposing VM public IPs. Incorrect options: Bastion Basic does not support the required features like 'Allowed IP Addresses' or 'Shareable Bastion Connect', and peering a Basic instance for cross-VNet access isn't a direct solution for all requirements. While a high SKU might handle sessions, Azure Firewall isn't the primary mechanism for Bastion source IP restriction, and direct VPN access for contractors defeats the purpose of secure, link-based access via Bastion. 'AllowExternalConnections' is not a standard Bastion feature for creating public links to VMs; Bastion's core purpose is to avoid public exposure. Scaling off would also limit session capacity.
