Question
Your company has an office in New York.
The company has an Azure subscription that contains the virtual networks shown in the following table.
| Name | Location |
|---|---|
| Vnet1 | East US |
| Vnet2 | North Europe |
| Vnet3 | West US |
| Vnet4 | West Europe |
You need to connect the virtual networks to the office by using ExpressRoute. The solution must meet the following requirements:
- The connection must have up to 1 Gbps of bandwidth.
- The office must have access to all the virtual networks.
- Costs must be minimized.
How many ExpressRoute circuits should be provisioned, and which ExpressRoute SKU should you enable?
- A. one ExpressRoute Premium circuit Correct
- B. two ExpressRoute Premium circuits
- C. four ExpressRoute Standard circuits
- D. one ExpressRoute Standard circuit
Explanation
A Standard ExpressRoute circuit only reaches Azure regions in the same geopolitical area as its peering location, so a circuit in North America cannot link to the virtual networks in North Europe and West Europe. ExpressRoute Premium adds global connectivity, letting a single circuit link virtual networks in any region, which meets the requirement with the fewest circuits. A single Standard circuit cannot reach the European virtual networks, and two or four circuits cost more than one Premium circuit.
