Google Cloud Professional Cloud Network Engineer — Question 2

You want to configure load balancing for an internet-facing, standard voice-over-IP (VOIP) application.
Which type of load balancer should you use?

Answer options

• A. HTTP(S) load balancer
• B. Network load balancer
• C. Internal TCP/UDP load balancer
• D. TCP/SSL proxy load balancer

Correct answer: B

Explanation

The Network load balancer is designed to handle high-throughput and low-latency connections, making it ideal for VOIP applications that require stable performance. The other options, such as the HTTP(S) load balancer, are better suited for web traffic rather than real-time voice data, while the Internal TCP/UDP load balancer and TCP/SSL proxy load balancer do not meet the requirements for internet-facing applications.
