AZ-900 Practice Question 54: ExpressRoute
Microsoft Azure Fundamentals (AZ-900) · Test 6 · question 4 of 10
A bank must connect its own datacenter to Azure with consistent latency and higher security than the public internet can offer. It accepts the lead time and the need to work with a connectivity provider. Which option should it choose?
Show answer and explanation
Answer:
ExpressRoute extends an on-premises network into the Microsoft cloud over a private connection, with the help of a connectivity provider. Microsoft states the benefit in the terms the stem uses: because ExpressRoute connections don't go over the public internet, they offer more reliability, faster speeds, consistent latencies, and higher security than typical connections over the internet. The provider relationship and the lead time are the price of that, and the bank has accepted both.
Option A misreads point-to-site VPN, which is established between a virtual network and a *single computer* that configures its own connection, a getting-started or developer option, and it still tunnels over the internet. Option B is the trap the word "global" sets: peering connects Azure *virtual networks* to one another, whether in the same region or across regions, and it cannot reach an on-premises datacenter. Option D filters *who* may connect but changes nothing about *where the packets travel*; the traffic still crosses the public internet.
