AWS Certified Solutions Architect Associate SAA-C03 Practice Question

The right choice here is the Application Load Balancer combined with an Auto Scaling group. The Application Load Balancer excels at managing inbound HTTP/HTTPS traffic, directing it across multiple destinations, such as EC2 instances, containers, IP addresses, and Lambda functions, which allows for fine-grained control, especially with HTTP/S requests. When paired with an Auto Scaling group, it facilitates adjustment to the cyclicality of web traffic by scaling the virtual servers' capacity up or down. The Network Load Balancer, though suitable for handling extreme performance requirements, doesn't pair intrinsically with virtual server scaling strategies. The CloudFront service is primarily a content distribution network to cache content closer to users globally, rather than for scaling server response to direct web traffic. Direct Connect is a service to establish a private connection from a private network to the cloud, and Route 53 is a Domain Name System web service that is unrelated to traffic distribution amongst servers. The use of a Spot Fleet could optimize costs when acquiring compute capacity but does not inherently address traffic distribution or scaling.
