A small remote office needs to establish a secure encrypted connection to an Azure virtual network for several on-premises client devices. The team has no dedicated hardware VPN appliance and needs to be up and running within hours. Which Azure connectivity option best meets these requirements?

Correct answer: Azure Point-to-Site VPN using the native Azure VPN client

Option C is correct because Point-to-Site VPN allows individual client devices to connect to an Azure virtual network over the internet using software clients with no on-premises VPN hardware required, and setup can be completed in a matter of hours. Option A describes ExpressRoute, which requires ordering a private circuit through a connectivity provider, a process that typically takes weeks to provision. Option B describes Site-to-Site VPN, which requires a compatible on-premises VPN gateway device and is intended for connecting entire networks rather than individual client devices. Option D describes Azure Virtual WAN, which is a managed networking service suited for large-scale branch connectivity and requires considerably more planning and configuration than a Point-to-Site deployment.
