Google Cloud Associate Cloud Engineer — Question 103

You have an application that receives SSL-encrypted TCP traffic on port 443. Clients for this application are located all over the world. You want to minimize latency for the clients. Which load balancing option should you use?

Answer options

• A. HTTPS Load Balancer
• B. Network Load Balancer
• C. SSL Proxy Load Balancer
• D. Internal TCP/UDP Load Balancer. Add a firewall rule allowing ingress traffic from 0.0.0.0/0 on the target instances.

Correct answer: C

Explanation

The SSL Proxy Load Balancer is ideal for handling SSL traffic as it can decrypt the SSL connections before forwarding them to the backend, which can help reduce latency. The HTTPS Load Balancer is also capable of handling SSL but is more suited for HTTP traffic and may not optimize performance as effectively as the SSL Proxy. The Network Load Balancer operates at a lower level and does not handle SSL termination, while the Internal TCP/UDP Load Balancer is not applicable for external client traffic.
