Q

Determine Gateway Transit and connectivity needs

A

Gateway transit allows peered virtual networks to share the gateway and get access to resources

No VPN gateway is required in the peered spoke network

Default VNet peering provides full connectivity

IP address spaces of connected networks cant overlap.

Q

Determine service chaining uses

A

Leverage user defined routes and service chaining to implement custom routing

Implement a VNet hub with network virtual appliance or VPN gateway

Service Chaining enables you to direct traffic from one virtual network to a virtual appliance , or virtual network gateway , in a peered virtual network , through user defined routes

Q

Review System Routes

A

Directs network traffic between virtual machines , on prem networks , and the internet.
System routes is used when:
Traffic between VMs in the same subnet

Between VMs in different subnets in the same virtual network

data flow from VMs to the internet

Communication between VMs using a VNet To VNet VPN

Site to Site and expressRoute communication through the VPN gateway.

VPN is needed only when you trying to connect VNets that are from your on on prem to azure , AWS , and other cloud providers

Q

Identify User defined Routes

A

A route table contains a set of rules called routes , that specifies how packets should be routed in a virtual network

User defined routes are custom routes that specify the next hop of traffic flow

The next hop can be a virtual network , gateway , internet or virtual appliance.

Review https://learn.microsoft.com/en-us/azure/virtual-network/virtual-networks-udr-overview#system-routes to see how azure routes the traffic
