You are the architect of the ACME shipping group. You are responsible for designing remote connectivity between 4 of your branches and your main virtual network in Azure. The connection needs to be secure and no additional intervention to connect from the remote branches to Azure and vice versa. Additional remote branches are also to be connected to Azure in the future, however, there is no need for the remote branches to communicate with each other directly. What connectivity solution should be used?
Site-to-Site VPN is correct as this solution is correct and supports up to 30 simultaneous connections as well as no user intervention to access the other sites. Point-to-Site VPN will not suffice as this is used for remote users to connect individually to the Azure VNets. Virtual Network Peering will not suffice as this is used to connect virtual networks in Azure with each other. Express route will not suffice as this is considerably costlier than Site-to-Site VPN. Express route will not suffice as this is used to connect large sites to Azure directly with low latency and high bandwidth.
