Answer: Implement NLB with target group and Auto Scaling group association, and utilize Route 53 latency records with CloudFront for origin.
The correct option is C. Using a Network Load Balancer (NLB) is suitable for UDP connections, which VoIP services typically use. The solution also includes setting up an Amazon Route 53 latency-based routing policy to ensure users are directed to the region with the lowest latency. Additionally, by creating an Amazon CloudFront distribution that uses the latency record as an origin, the system can distribute traffic efficiently and provide automatic failover between regions. This ensures both low latency and high availability for the VoIP service.
