Zorluk: OrtaConfigure Virtual Network Peering

You manage three Azure virtual networks in the West US region:
* `VNet-Transit` (172.20.0.0/16172.20.0.0/16) contains a Virtual Network Gateway configured for an ExpressRoute connection to your on-premises datacenter.
* `VNet-App` (172.21.0.0/16172.21.0.0/16) contains virtual machines running web applications.
* `VNet-Database` (172.22.0.0/16172.22.0.0/16) contains virtual machines running database instances.

You configure virtual network peering between `VNet-Transit` and `VNet-App`, and between `VNet-Transit` and `VNet-Database`.

You need to ensure that the virtual machines in both `VNet-App` and `VNet-Database` can connect to the on-premises datacenter through the Virtual Network Gateway in `VNet-Transit`.

Which configuration must you apply to the peering links?

  1. Configure the peering links from `VNet-Transit` to enable Allow gateway transit, and configure the peering links from `VNet-App` and `VNet-Database` to enable Use remote gateways.Cevap
  2. B
    Configure the peering links from `VNet-Transit` to enable Use remote gateways, and configure the peering links from `VNet-App` and `VNet-Database` to enable Allow gateway transit.
  3. C
    Configure the peering links from `VNet-Transit` to enable Allow forwarded traffic, and configure the peering links from `VNet-App` and `VNet-Database` to enable Allow forwarded traffic.
  4. D
    Deploy a Virtual Network Gateway in both `VNet-App` and `VNet-Database`, and configure the peering links to enable Allow gateway transit on all connections.

Cevap

Configure the peering links from `VNet-Transit` to enable Allow gateway transit, and configure the peering links from `VNet-App` and `VNet-Database` to enable Use remote gateways.
To allow spoke virtual networks (`VNet-App` and `VNet-Database`) to use the VPN or ExpressRoute gateway in a hub virtual network (`VNet-Transit`), you must enable gateway transit. This is done by configuring Allow gateway transit on the peering link from the hub virtual network (`VNet-Transit`) to the spokes and configuring Use remote gateways (or 'Use this virtual network's gateway or Route Server') on the peering links from the spoke virtual networks (`VNet-App` and `VNet-Database`) to the hub.

Adım Adım Çözüm

1
Identify the hub-and-spoke relationship between the virtual networks.
`VNet-Transit` acts as the hub since it hosts the Virtual Network Gateway, while `VNet-App` and `VNet-Database` act as spokes.
Determining the network roles identifies which network must share its gateway resources.
2
Enable the sharing capability on the hub virtual network.
Enable Allow gateway transit on the peering links originating from `VNet-Transit`.
This configuration permits the hub to route spoke traffic through its local gateway.
3
Configure the spoke networks to utilize the shared resource.
Enable Use remote gateways on the peering links originating from both `VNet-App` and `VNet-Database`.
This instructs the spokes to route external traffic to the remote gateway located in the peered hub network.
