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 LS 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 5KU should you enable?

Answer options

Correct Answer:

Explanation

The virtual networks are located in two different Azure geopolitical regions: North America (East US, West US) and Europe (North Europe, West Europe). An ExpressRoute Standard circuit only provides access to Azure regions within the same geopolitical region as the peering location (in this case, North America). To connect the New York office to all virtual networks, including those in the Europe geopolitical region, global connectivity is required. The ExpressRoute Premium add-on provides this global connectivity. Therefore, a single ExpressRoute Premium circuit is the most cost-effective solution that meets all requirements.

Why Incorrect

A. one ExpressRoute Standard circuit: A Standard circuit would not provide connectivity to the virtual networks in the Europe geopolitical region from a North American peering location.

C. two ExpressRoute Premium circuits: This is not a cost-minimized solution, as a single Premium circuit is sufficient to provide the required global connectivity.

D. four ExpressRoute Standard circuits: This solution is unnecessarily complex, significantly more expensive, and does not meet the requirement for global connectivity from a single office.

1. Microsoft Learn

"ExpressRoute circuits and peering": Under the "ExpressRoute SKUs" section

it states

"ExpressRoute Standard SKU gives you connectivity to all Azure regions in a geopolitical region... ExpressRoute Premium SKU provides connectivity to all Azure regions globally." This directly contrasts the capabilities of the two SKUs.

2. Microsoft Learn

"ExpressRoute FAQ": In the "What is ExpressRoute Premium?" section

it clarifies

"A VNet created in one geopolitical region can be accessed through an ExpressRoute circuit in another geopolitical region. For example

you can create a virtual network in West Europe and link it to an ExpressRoute circuit created in Silicon Valley." This confirms Premium is needed for the scenario.

3. Microsoft Learn

"ExpressRoute locations and connectivity providers": The table under "Locations by geopolitical region" confirms that "North America" and "Europe" are distinct geopolitical regions

necessitating the Premium SKU for cross-region connectivity as described in the question.
