Question
You have an Azure subscription that contains a virtual network.
You plan to deploy an Azure VPN gateway and 90 Site-to-Site VPN connections. The solution must meet the following requirements:
- Ensure that the Site-to-Site VPN connections remain available if an Azure datacenter fails.
- Minimize costs.
Which gateway SKU should you specify?
- A. VpnGw1AZ
- B. VpnGw2AZ
- C. VpnGw4AZ Correct
- D. VpnGw5AZ
Explanation
The AZ SKUs are zone-redundant, so the gateway keeps working if one datacenter (availability zone) fails. VpnGw1AZ, VpnGw2AZ and VpnGw3AZ support at most 30 Site-to-Site tunnels, which is not enough for 90 connections. VpnGw4AZ and VpnGw5AZ support up to 100 tunnels, and VpnGw4AZ is the cheaper of the two.
