Routing preference is a feature that allows you to configure how network traffic is routed to your storage account from clients over the internet. By default, traffic from the internet is routed to the public endpoint of your storage account over the Microsoft global network, which is optimized for low-latency path selection and high reliability. Both inbound and outbound traffic are routed through the point of presence (POP) that is closest to the client. This ensures that traffic to and from your storage account traverses over the Microsoft global network for the bulk of its path, maximizing network performance. You can also change the routing preference to use internet routing, which minimizes the traversal of your traffic over the Microsoft global network, handing it off to the transit ISP at the earliest opportunity. This lowers networking costs, but may compromise network performance. Therefore, to ensure that inbound user traffic uses the Microsoft POP closest to the user's location, you should configure routing preference to use the Microsoft global network as the default routing option for your storage account.

To ensure that User1 can deploy virtual machines and manage virtual networks, you need to assign an RBAC role that grants the necessary permissions to perform these tasks. The solution must also use the principle of least privilege, which means that you should only grant the minimum level of access required to accomplish the goal.
Based on these requirements, the best RBAC role to assign to User1 is D. Virtual Machine Contributor. This role allows User1 to create and manage virtual machines, disks, snapshots, and network interfaces. It also allows User1 to connect virtual machines to existing virtual networks and subnets. However, it does not allow User1 to create or delete virtual networks or subnets, or to access the virtual machines themselves. This role follows the principle of least privilege by limiting User1's access to only the resources and actions that are relevant to deploying virtual machines and managing virtual networks1.

Ensure port 445 is open: The SMB protocol requires TCP port 445 to be open; connections will fail if port
445 is blocked.
