Objective 2.4
PCNEConfiguring and maintaining GKE clusters
Objective 2.4 sits in Implementing a VPC network, which carries 20% of the Cloud Network Engineer exam. The questions below are original, written from the official objective title above, and each explanation cites the Google Cloud page it rests on.

A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
An application team creates an HTTPRoute that names a Gateway in another namespace, and the route never takes effect. What else has to happen?
Correct.
Concept
An attachment that both sides must consent to cannot be completed from one side alone, however correctly that side is configured.
Why A
Gateway and Route binding is bidirectional, so both resources have to select each other before the binding comes into effect.
Source
About Gateway API in GKE, checked August 2026An HTTPRoute defines which Gateways it can route traffic from, which Services to route to, and rules that define what traffic the HTTPRoute matches. Gateway and Route binding is bidirectional, which means that both resources must select each other for them to bind.
Now you: objective 2.4 questions
No account needed. The explanation opens when you answer.
Sample question 1 of 3
An HTTPRoute in the frontend namespace has to send traffic to a Service in the backend namespace. Where does the ReferenceGrant belong?
Sample question 2 of 3
A team needs to change how the load balancer behind a Gateway spreads traffic across the endpoints of a backend service. Which resource carries that setting?
Sample question 3 of 3
A platform team wants to own IP allocation, ports and TLS while letting application teams control their own routing rules. Which split of resources delivers that?
