What should you include in the recommendation?

Answer options

Correct answer: A

Explanation

Azure Front Door is the correct choice as it meets all specified requirements, including regional failover, WAF support, cookie-based affinity, and URL routing. Azure Traffic Manager primarily focuses on DNS-based routing and does not provide WAF capabilities, while Azure Application Gateway is designed for application-level load balancing but lacks global routing features. Azure Load Balancer is not suitable for application-level features like WAF or cookie affinity.
