Google Cloud Professional Cloud Network Engineer — Question 48

You create multiple Compute Engine virtual machine instances to be used at TFTP servers.
Which type of load balancer should you use?

Answer options

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

Correct answer: D

Explanation

The Network load balancer is the correct choice because it operates at the transport layer and can handle UDP traffic, which is essential for TFTP. The other options, such as HTTP(S) and SSL proxy load balancers, are designed for HTTP and TCP traffic, respectively, making them unsuitable for TFTP's requirements.
