Networking: Peering and VWAN Flashcards

1
Q

VNet peering

A

Virtual network peering enables you to seamlessly connect two Azure virtual networks (private connections). Once peered, the virtual networks appear as one, for connectivity purposes.

Q

Global VNet peering

A

connects Azure virtual networks in different regions. When creating a global peering, the peered virtual networks can exist in any Azure public cloud region or China cloud regions, but not in Government cloud regions.

Q

VNet Peering: Service Chaining

A

VNet Peering is nontransitive. (if VNet1 and Vnet2 are peered, Vnet2 and Vnet3 are peered, Vnet1 and Vnet3 are NOT peered)

user-defined routes and service chaining can provide the transitivity.

Service chaining lets you define user routes. These routes direct traffic from one virtual network to a virtual appliance, or virtual network gateway.

Q

Benefits of VNet Peering - Seamless

A

The ability to transfer data across Azure subscriptions, deployment models, and across Azure regions.

No disruption. No downtime to resources in either virtual network when creating the peering, or after the peering is created.

Q

VWAN Resources: Hub

A

A virtual hub is a Microsoft-managed virtual network.

The hub contains various service endpoints to enable connectivity.

17
Q

VWAN Resources: Hub virtual network connection

A

The Hub virtual network connection resource is used to connect the hub seamlessly to your virtual network. One virtual network can be connected to only one virtual hub.

18
Q

VWAN Resources: Hub-to-Hub connection

A

Hubs are all connected to each other in a virtual WAN.

You can connect VNets within a hub transiting through the virtual hub, as well as VNets across hub, using the hub-to-hub connected framework.

19
Q

VWAN Resources: Hub Route Table

A

You can create a virtual hub route and apply the route to the virtual hub route table. You can apply multiple routes to the virtual hub route table.

20
Q

VWAN Connection Configurations: Site-to-SiteVPN

A

You can connect to your resources in Azure over a Site-to-site IPsec/IKE (IKEv2) connection.

This type of connection requires a VPN device or a Virtual WAN Partner device.

21
Q

VWAN Connection Configurations: User VPN (Point-to-site)

A

You can connect to your resources in Azure over an IPsec/IKE (IKEv2) or OpenVPN connection.

This type of connection requires a VPN client to be configured on the client computer.

22
Q

VWAN Connection Configurations: ExpressRoute Connections

A

ExpressRoute lets you connect on-premises network to Azure over a private connection. To create the connection, see Create an ExpressRoute connection using Virtual WAN.

23
Q

VWAN Connection Configurations: Hub-to-VNet Connections

A

You can connect an Azure virtual network to a virtual hub.
