CASE STUDY (Questions 51-55)

Contoso Financial is a global investment bank.

Current Infrastructure:

• On-premises datacenters in New York, London, and Tokyo.
• Azure regions used: US East, Europe West, Japan East.
• Each on-premises datacenter is connected to its local Azure region via a 10 Gbps ExpressRoute circuit.
• Azure architecture uses a Hub-and-Spoke topology in each region.

Business Requirements:

• The network architecture must support global failover. If the US East region fails, the New York datacenter must be able to route traffic to the Europe West Azure region.
• All outbound internet traffic from Azure VMs must be inspected by a centralized firewall.
• Azure PaaS services (SQL, Storage) must not be accessible from the public internet.
• Network management overhead must be minimized as the company plans to add 50 more spoke VNets per region next year.

Question 1 of 5:
To meet the global failover requirement, the New York datacenter must be able to communicate with the Europe West Azure region if US East fails.

Which ExpressRoute feature or architecture should you implement?
