Question No. 14
[Optimizing service performance]
You support the backend of a mobile phone game that runs on a Google Kubernetes Engine (GKE)
cluster. The application is serving HTTP requests from users. You need to implement a solution that
will reduce the network cost. What should you do?
Select one option, then reveal solution.

D imo. Setting up a Google Cloud HTTP Load Balancer as Ingress can help optimize traffic routing and reduce unnecessary outgoing network hops, which should lower network costs. It’s designed for handling external HTTP traffic efficiently, and GKE integrates well with it.

Options like A and B don’t directly address network cost reduction from the HTTP traffic perspective, and C (Private Cluster) is more about security/isolation rather than cost savings on incoming user requests. So, D feels like the most solid bet here.

Probably B here. Using Standard Tier for network services is cheaper than Premium Tier, so switching to Standard Tier should cut network costs. The question doesn’t mention any particular security or performance needs that require Premium Tier, so this seems like a straightforward way to reduce cost without changing the cluster setup.

Also, the Private Cluster (C) mainly helps with security and internal access, but it doesn’t directly reduce network egress costs for user HTTP requests coming from outside. So B feels more aligned with just lowering cost.

Maybe C makes sense since a Private Cluster limits egress traffic through the internet, which should cut down network costs. It keeps traffic internal to Google’s network.

Does the question specify if the users are accessing from within the same VPC or public internet?
