Topic 1 Question 18
Your company's web server administrator is migrating on-premises backend servers for an application to GCP. Libraries and configurations differ significantly across these backend servers. The migration to GCP will be lift-and-shift, and all requests to the servers will be served by a single network load balancer frontend. You want to use a GCP-native solution when possible. How should you deploy this service in GCP?
Create a managed instance group from one of the images of the on-premises servers, and link this instance group to a target pool behind your load balancer.
Create a target pool, add all backend instances to this target pool, and deploy the target pool behind your load balancer.
Deploy a third-party virtual appliance as frontend to these servers that will accommodate the significant differences between these backend servers.
Use GCP's ECMP capability to load-balance traffic to the backend servers by installing multiple equal-priority static routes to the backend servers.

Correct Answer: B
👍 9Jerrard2020/10/14B for sure. It cannot be a managed instance group bc we cannot scale unidentical VMs. We can either use an unmanaged instance group or a target pool (for only NW LBer)
👍 4seddy2021/05/17Answer is B: https://cloud.google.com/load-balancing/docs/target-pools
'External TCP/UDP Network Load Balancing can use either a backend service or a target pool to define the group of backend instances that receive incoming traffic'
'Target pools work with forwarding rules that handle TCP and UDP traffic. You must create a target pool before you can use it with a forwarding rule.'
