AZ-305 Question 233
Select 2Your organization runs a global, stateless web application across multiple Azure regions. End users in remote geographies experience high latency when accessing the application. You need to recommend solutions that minimize latency and ensure high availability. Which two solutions should you recommend? (Choose two.)
- A
A. Use Azure Front Door to route users to the nearest Azure region and provide global load balancing
- B
B. Enable Accelerated Networking on all VMs hosting the front-end services
- C
C. Configure Azure Traffic Manager with Priority routing to direct all user traffic to a single primary region
- D
D. Establish Site-to-Site VPN tunnels from each global user location to all Azure regions
Show answer and explanation
Correct answers: A, B
Explanation
To optimize network performance for globally distributed user bases, a combination of global load balancing (Azure Front Door) and optimized VM networking (Accelerated Networking) is often recommended. Azure Front Door routes users to the nearest Azure region, decreasing round-trip times and improving application availability. Meanwhile, Accelerated Networking on Azure VMs enhances throughput and reduces latency by offloading network processing to the hardware. Refer to Azure Front Door documentation (https://learn.microsoft.com/azure/frontdoor/front-door-overview) and Accelerated Networking documentation (https://learn.microsoft.com/azure/virtual-network/create-vm-accelerated-networking) for more details.
- A. Correct.
A. Correct. Azure Front Door can distribute traffic to the closest region, reducing latency and offering high availability through global load balancing. It also supports features such as SSL offloading and application-level routing.
- B. Correct.
B. Correct. Accelerated Networking reduces CPU overhead and improves throughput, which can significantly lower latency for high-traffic workloads on Azure VMs.
- C. Incorrect.
C. Incorrect. Priority routing sends most or all traffic to a single primary region, which may not minimize latency for users in geographically distant areas. Performance routing, not Priority, would be more suitable for latency optimization.
- D. Incorrect.
D. Incorrect. Site-to-Site VPN is typically used for secure communication between on-premises networks and Azure. It does not generally help reduce latency for end users connecting from multiple global locations over the public internet.
