AZ-700 Question 124
Select 2Your organization has a global presence with offices in Europe, North America, and Asia that need secure, high-bandwidth connectivity to Azure resources. You plan to use a single ExpressRoute circuit to provide connectivity for these offices to Azure regions worldwide. Additionally, you want to use Microsoft 365 consumption over the same circuit and anticipate a large number of BGP routes. You are deciding whether an ExpressRoute Standard or Premium tier is necessary to meet these requirements. Which two statements are correct about selecting an ExpressRoute SKU and tier for these requirements?
- A
Remain on ExpressRoute Standard because it provides global connectivity by default and meets all route limits.
- B
Upgrade to ExpressRoute Premium to enable worldwide connectivity across all Azure regions and higher route capacities.
- C
Use multiple ExpressRoute Local circuits in each geographic location because ExpressRoute Standard covers all necessary peering requirements.
- D
ExpressRoute Premium is typically required for Microsoft 365 connectivity in large-scale global deployments, due to higher route limits and global routing.
Show answer and explanation
Correct answers: B, D
Explanation
In scenarios requiring worldwide access to Azure services from a single circuit, plus the ability to handle Microsoft 365 traffic and a large number of BGP routes, ExpressRoute Premium is typically necessary. The Standard tier limits connectivity to specific regional pairs and has lower route limits. Upgrading to Premium enables global routing across all Azure regions, increases the route limit capacity, and aligns with Microsoft� guidelines for Microsoft 365 over ExpressRoute in large or globally distributed environments. For more details, refer to Microsoft� official documentation on ExpressRoute circuits: https://docs.microsoft.com/azure/expressroute/expressroute-overview
- A. Incorrect.
Option 1 is incorrect. ExpressRoute Standard does not automatically provide global connectivity across all Azure regions, and it has lower route limits than the Premium tier, which can be a constraint for large deployments.
- B. Correct.
Option 2 is correct. ExpressRoute Premium allows global connectivity to all Azure regions and permits larger BGP route advertisements, making it suitable for multi-region scenarios.
- C. Incorrect.
Option 3 is incorrect. While ExpressRoute Local can reduce costs for local data ingress/egress, it does not provide global connectivity. You would need multiple local circuits for each region, which defeats the goal of using a single circuit for worldwide coverage.
- D. Correct.
Option 4 is correct. For large-scale global deployments, particularly those involving Microsoft 365, Premium tier is often required due to increased route limits and the ability to connect to multiple regions through a single circuit.
