Topic 1 Question 148
You are designing a new application that has backends internally exposed on port 800. The application will be exposed externally using both IPv4 and IPv6 via TCP on port 700. You want to ensure high availability for this application. What should you do?
Create a network load balancer that used backend services containing one instance group with two instances.
Create a network load balancer that uses a target pool backend with two instances.
Create a TCP proxy that uses a zonal network endpoint group containing one instance.
Create a TCP proxy that uses backend services containing an instance group with two instances.

- 正解だと思う選択肢: A
A is the correct, since with need to support IPV6: "Target pool-based network load balancers support only IPv4 traffic, and only support the TCP and UDP protocols." https://cloud.google.com/load-balancing/docs/network/networklb-target-pools
👍 8pfilourenco2022/12/05 D is the correct answer. The question has 3 criteria. High availability, IPv4 and IPv6 support, and translate the front end port to a different backend port.
Answer A - Can not be correct because a Network load balancer is pass-through, the front end port and backend port will allways be the same. Answer B - same reason Answer C - Does not meet the HA requirement Answer D - Meets all 3 requirements, HA with 2 instance instance group, IPV4 and 6 support, and the port change requirement provided by the proxy component of the TCP LB.

Totally assumed LB after the TCP Proxy. Tricky stuff. Answer should be A.
