-Zone-redundant gateways and zonal gateways both rely on the Azure public IP resource *Standard* SKU. The configuration of the Azure public IP resource determines whether the gateway that you deploy is zone-redundant, or zonal. If you create a public IP resource with a *Basic* SKU, the gateway won't have any zone redundancy, and the gateway resources will be regional.
+Zone-redundant, zonal and non-zonal gateways rely on the configuration of *Standard* SKU of Azure public IP resource. If you create a public IP resource with a *Basic* SKU, the gateway won't have any zone redundancy, and the gateway resources are regional.

 ### Can I deploy both VPN and ExpressRoute gateways in same virtual network?
 
-Co-existence of both VPN and ExpressRoute gateways in the same virtual network is supported. However, you should reserve a /27 IP address range for the gateway subnet.
