Which Microsoft Azure load balancing option resolves the same hostname to different IP addresses?

The correct answer is Traffic Manager. Microsoft Azure Traffic Manager is designed to route incoming traffic based on policies you define, such as performance, geographic location, or round-robin distribution. One of its key features is the ability to resolve a single hostname to multiple IP addresses. This capability allows Traffic Manager to route requests to different endpoints based on the configured rules, ensuring that clients are directed to the most appropriate service, which can help with load balancing and improving user experience.

Traffic Manager operates at the DNS level, meaning that when a client makes a request to a hostname managed by Traffic Manager, it returns the IP address of the most suitable endpoint based on the defined policies. This is particularly useful for applications that are distributed across multiple regions or that require failover capabilities, as it allows seamless redirection of traffic without changing the client-facing hostname.

In contrast, Azure Load Balancer and Application Gateway function differently, as they primarily balance traffic within Azure networks or manage incoming web traffic, respectively, but do not specifically feature the DNS-based resolution of multiple IPs under a single hostname. Azure DNS Balancer, while it deals with DNS records, does not perform load balancing in the same context as Traffic Manager and does not resolve hostnames to various IP addresses dynamically based
