Exam Associate Cloud Engineer topic 1 question 167 discussion

Answer is D, cell phones are sending UDP packets and the only that can receive that type of traffic is a External Network TCP/UDP https://cloud.google.com/load-balancing/docs/network

Answer is D. there are so many confusion here, from B,C or D. For myself im eliminating all options except B,D due to the traffic type. which leaves me with B or D. Then next the traffic source either external or internal which in this case is an external traffic from the internet, therefore my final answer is D. https://cloud.google.com/load-balancing/docs/choosing-load-balancer

1. UDP Traffic Support: • An external Network Load Balancer in Google Cloud supports both TCP and UDP traffic. Since your game uses UDP packets for multiplayer interactions, the Network Load Balancer is appropriate for handling this type of traffic. 2. Single IP for Multiple VMs: • Network Load Balancers allow you to use a single, anycast IP address that can distribute incoming traffic across multiple VMs in your backend. This aligns with your requirement to expose the backend servers through a single IP address.

for udp external load balancer, D is the correct answer

By elimination A: SSL proxy LB is for TCP traffic not for UDP, eliminated B: External LB is required, Eliminated C: Http LB works at layer 7, here protocol is UDP, eliminated D: Correct answer

"Correct Answer" says A and community vote says D(100%) which one is correct?

Going with D

Ans is D

The question tricked me. I saw UDP and immediately thought it was B. The correct answer is D, as the LB needs to be External, and SSL\HTTPS are not the right load balancers for this application.

External Network LB used for UDP

D seems correct..

I'm dead sure, it's D!

D, because: https://cloud.google.com/load-balancing/docs/network#:~:text=Google%20Cloud%20external-,TCP/UDP,-Network%20Load%20Balancing

Answer is C. Players need to access through internet by HTTP(S) load balancing

The key statement we need to watch out for ; "And you want to expose the Vms over a single IP address'' . Google Cloud external TCP/UDP Network Load Balancing (after this referred to as Network Load Balancing) is a regional, "pass-through" load balancer. A network load balancer "distributes external traffic among virtual machine (VM) instances" in the same region. You can configure a network load balancer for TCP, UDP, ESP, and ICMP traffic. https://cloud.google.com/load-balancing/docs/network

My answer here is A for the following reasons. Feel free to comment if I missed something. 1. For a mobile game to reach its maximum audience, it must be available globally. SSL proxy LB supports global load balancing service with the Premium Tier. 2. It is intended for non-HTTP(S) traffic. For HTTP(S) traffic, GCP recommends using HTTP(S) Load Balancing. 3. Preserves the original source IP addresses of incoming connections to the load balancer 4. SSL proxy LB allows you to expose a single IP address https://cloud.google.com/network-tiers/docs/overview#configuring_standard_tier_for_https_lb_and_tcpssl_proxy https://cloud.google.com/load-balancing/docs/ssl
