VPN Gateway, ExpressRoute, and Hybrid Connectivity Decisions
A scenario-driven lab: compare VPN Gateway, ExpressRoute, and Virtual WAN, size a gateway SKU, design hybrid DNS, and build the live network foundation a gateway attaches to without waiting 30-45 minutes for a gateway to provision.
Lab Overview
Hybrid connectivity is a core AZ-104 networking topic, but live VPN gateway provisioning takes 30 to 45 minutes and ExpressRoute is impractical and costly to provision in a student lab. This is a scenario-and-artifact lab, not a live gateway deployment lab.
You will analyze a hybrid connectivity requirement set, choose between VPN Gateway, ExpressRoute, and Virtual WAN, size a VPN gateway SKU, and design hybrid DNS resolution, recording each decision as a reviewable architecture artifact.
The only live, Contributor-safe work is building the network foundation that a gateway would attach to: a virtual network, a correctly named GatewaySubnet sized at /27, and a Standard static public IP for the gateway. You will inspect and validate that foundation. The gateway itself, ExpressRoute, and Virtual WAN remain documented walkthroughs and decision artifacts so the lab never waits on gateway provisioning.
What You'll Learn

Build the live network foundation for a gateway: a VNet, a GatewaySubnet sized at /27, and a Standard static public IP
Document the az network vnet-gateway create command without waiting on live gateway provisioning
Design a hybrid DNS forwarding pattern for on-premises and Azure name resolution
Prerequisites
