Correct answer: Network load balancer.
Why this is the answer
A Network Load Balancer is the correct choice because TFTP (Trivial File Transfer Protocol) uses UDP, not TCP or HTTP(S). Network Load Balancers are designed for non-HTTP(S) protocols and can handle UDP traffic at Layer 4. HTTP(S) load balancers are for HTTP and HTTPS traffic. SSL proxy load balancers and TCP proxy load balancers operate at Layer 4 but are specifically for TCP traffic, not UDP. Since TFTP operates over UDP, these options are unsuitable.
