AZ-305 Question 232
Select 2Your organization runs a web application with users across multiple continents. The application is deployed in Azure across multiple regions and serves both static and dynamic content. Users outside the primary Azure region report slow page loads and high latency. You want to ensure that all customers, regardless of location, experience fast response times. Which two solutions should you recommend to optimize global network performance?
- A
Use Azure Front Door to route incoming requests to the nearest Azure region based on performance and latency metrics
- B
Implement an Azure Content Delivery Network (CDN) to cache static assets closer to users around the world
- C
Configure Azure ExpressRoute for all web traffic to eliminate latency for external users
- D
Set up Azure Load Balancer in each region for global user redirection at Layer 4
Show answer and explanation
Correct answers: A, B
Explanation
Combining Azure Front Door’s global load balancing and Azure CDN’s edge caching provides an optimal solution for reducing latency worldwide. Azure Front Door distributes dynamic requests to the nearest region, while Azure CDN ensures static and media assets are served from globally distributed edge locations. For more details, refer to the Azure Front Door documentation (https://learn.microsoft.com/azure/frontdoor/front-door-overview) and Azure CDN documentation (https://learn.microsoft.com/azure/cdn/cdn-overview).
- A. Correct.
Azure Front Door is designed for global load balancing and can route requests to the nearest Azure region based on performance metrics. This reduces latency and improves user experience for a geographically distributed user base.
- B. Correct.
An Azure CDN allows caching of static content closer to the end users through points of presence around the globe. This significantly improves the performance of serving images, scripts, and other static files.
- C. Incorrect.
Azure ExpressRoute is intended to create private, dedicated network connections between on-premises networks and Azure. It does not directly optimize public user traffic coming from the internet, so it wouldn't solve global latency for external users alone.
- D. Incorrect.
Azure Load Balancer operates at Layer 4 and primarily handles traffic within a single region or across Availability Zones. It does not provide global routing based on latency or caching capabilities.
