Selected Answer: A
Yes, using Azure Front Door to provide access to the app meets the goal. Azure Front Door is a global, scalable entry-point that uses the Microsoft global edge network to create fast, secure, and widely distributed web applications. It supports the following requirements: Rate limiting: Azure Front Door, when combined with Azure Web Application Firewall (WAF), supports rate limiting to protect your web applications from malicious attacks or excessive request rates. Load balancing: Azure Front Door provides global load balancing to distribute incoming traffic across multiple instances of your web app, improving availability and responsiveness. Regional outage resilience: In the event of a regional outage, Azure Front Door can automatically route users to the closest available instance of your web app, ensuring continued access.

Given answer A is correct as Azure FD combined with WAF policy will achieve all that, as note also Azure App GWY can achieve same with WAF policy but Azure App GWY doesn't provide Global redundancy, ONLY per region (Azure App GWY was answer in another question which is B)

https://learn.microsoft.com/en-us/azure/web-application-firewall/afds/waf-front-door-rate-limit Rate limiting enables you to detect and block abnormally high levels of traffic from any socket IP address. The socket IP address is the address of the client that initiated the TCP connection to Front Door. Typically, the socket IP address is the IP address of the user, but it might also be the IP address of a proxy server or another device that sits between the user and Front Door. By using the web application firewall (WAF) with Azure Front Door, you can mitigate some types of denial of service attacks. Rate limiting also protects you against clients that have accidentally been misconfigured to send large volumes of requests in a short time period. Rate limits are applied at the socket IP address level. If you have multiple clients accessing your Front Door from different socket IP addresses, they'll each have their own rate limits applied. The socket IP address is the source IP address WAF sees. If your user is behind a proxy, socket IP address is often the proxy server address.

https://learn.microsoft.com/en-us/azure/web-application-firewall/afds/waf-front-door-rate-limit What is the difference between Azure Front Door and Azure Application Gateway? While both Front Door and Application Gateway are layer 7 (HTTP/HTTPS) load balancers, the primary difference is that Front Door is a non-regional service whereas Application Gateway is a regional service. While Front Door can load balance between your different scale units/clusters/stamp units across regions, Application Gateway allows you to load balance between your VMs/containers etc. that is within the scale unit.
