Selected Answer: A
A. Azure Front Door Azure Front Door is the recommended load balancing service for the planned deployment as it meets all the specified requirements: ✓ Maintains access to the app in the event of a regional outage, as it is a global load balancer with instant failover capabilities. ✓ Supports Azure Web Application Firewall (WAF) integration for security. ✓ Supports cookie-based affinity for session stickiness. ✓ Supports URL routing for directing traffic to different backend pools based on URL patterns.

Azure front door. While both azure application gateway and azure front door hit most of the requirements, the key requirement is the cross-region support. Azure Application Gateway is a regional service that distributes traffic within a region, while Azure Front Door is a global service that distributes traffic across regions. https://learn.microsoft.com/en-us/azure/frontdoor/standard-premium/faq#what-is-the-difference-between-azure-front-door-and-azure-application-gateway

A is the answer. https://learn.microsoft.com/en-us/azure/frontdoor/routing-methods#affinity Session affinity can be enabled the origin group level in Azure Front Door Standard and Premium tier and front end host level in Azure Front Door (classic) for each of your configured domains (or subdomains). Once enabled, Azure Front Door adds a cookie to the user's session. The cookies are called ASLBSA and ASLBSACORS. Cookie-based session affinity allows Front Door to identify different users even if behind the same IP address, which in turn allows a more even distribution of traffic between your different origins.

https://learn.microsoft.com/en-us/azure/web-application-firewall/afds/afds-overview zure Web Application Firewall (WAF) on Azure Front Door provides centralized protection for your web applications. WAF defends your web services against common exploits and vulnerabilities. It keeps your service highly available for your users and helps you meet compliance requirements. WAF on Front Door is a global and centralized solution. It's deployed on Azure network edge locations around the globe. WAF enabled web applications inspect every incoming request delivered by Front Door at the network edge. WAF prevents malicious attacks close to the attack sources, before they enter your virtual network. You get global protection at scale without sacrificing performance. A WAF policy easily links to any Front Door profile in your subscription. New rules can be deployed within minutes, so you can respond quickly to changing threat patterns.

Selected Answer: B
I believe that the correct answer is B. Traffic Manager. It supports Multi-region load balancing, WAF, Cookie-based session affinity and URL path https://docs.microsoft.com/en-us/azure/architecture/high-availability/reference-architecture-traffic-manager-application-gateway

Stop upvoting this. Traffic Manager rely on Application Gateway in this architecture. Application Gateway - While Traffic Manager provides DNS-based regional load balancing, Application Gateway gives you many of the same capabilities as Azure Front Door but at the regional level such as: Web Application Firewall (WAF) Transport Layer Security (TLS) termination Path-based routing Cookie-based session affinity

Traffic Manager is a DNS resolver ... used with Application Gateway may cover session affinity but on its own only Front Door meets the requirements.

Answer is correct, I was leaning towards C however AAG is regional and doesn't support path based routing Front Door is an application delivery network that provides global load balancing and site acceleration service for web applications. It offers Layer 7 capabilities for your application like SSL offload, path-based routing, fast failover, caching, etc. to improve performance and high-availability of your applications.
