Free Microsoft Azure AZ-700 Actual Exam Questions - Question 7 Discussion
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?
Not just bandwidth, but the global reach of Premium is crucial here. Since VNets span US and Europe, only one Premium circuit (B) can connect all without multiple expensive circuits.
This is tricky, but I think it has to be B. One Premium circuit covers global connectivity, so it can link the US and European VNets plus the office in one go, which keeps costs down versus multiple circuits. Standard circuits wouldn’t span those regions. Also, since the bandwidth cap is 1 Gbps total, a single circuit should handle it without needing to split. So, one Premium circuit makes the most sense here.
Actually, the key here is that Standard ExpressRoute circuits only cover connectivity within a geopolitical region, like US or Europe, but not across multiple regions. Since the company has virtual networks in both the US and Europe, you’d need more than one circuit to cover all locations unless you go Premium. So, just picking one Standard circuit (A) won’t work because it won’t connect all VNets to the office. That means either multiple circuits or a single Premium circuit is needed to meet the requirement of access to all VNets.
D imo, only one circuit is needed since Standard covers global regions up to 1 Gbps. Premium is overkill and would push costs up unnecessarily with multiple circuits.
B, since Premium is needed for cross-continental VNets beyond standard limits.
A/B? Standard supports global regions, so one circuit might be enough. Premium adds features but costs more. Since connections are only US and Europe, Standard should cover it, keeping costs low with 1 Gbps bandwidth.
Option A makes sense because a single ExpressRoute Standard circuit supports global connectivity across regions, which means your New York office can connect to all VNets in East US, West US, North Europe, and West Europe without needing multiple circuits. Premium is usually for more advanced features or more regions, but here it seems unnecessary and more costly. Also, having just one circuit keeps costs down as required, so no need to provision multiple circuits just to cover different locations.
B (doesn't Standard cover all regions though?)
