Answer: Network load balancer
For a standard internet-facing VOIP application, which typically uses UDP for real-time communication, the Network Load Balancer (Option B) is the correct choice. The Network Load Balancer operates at Layer 4 (TCP/UDP) and supports both regional and global traffic. It is designed for low-latency, high-performance scenarios like VOIP. The HTTP(S) Load Balancer (A) is Layer 7 and unsuitable for UDP. The Internal TCP/UDP Load Balancer (C) is for private/internal traffic, not internet-facing. The TCP/SSL Proxy Load Balancer (D) terminates TCP/SSL traffic but does not support UDP, making it incompatible with VOIP requirements.
