Configuring 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.

Shown solved, with the whole explanation open: this is what every question here carries.

2-4Implementing a VPC network

An application team creates an HTTPRoute that names a Gateway in another namespace, and the route never takes effect. What else has to happen?

The Gateway must permit that route as wellCorrect · your answerCorrect. Consent is needed from the other side too.
The route must be recreated in that namespaceNamespace placement is not what blocks the attachment.
The Gateway must be recreated after the routeOrdering of creation has no effect on the binding.
The route must list every backend explicitlyBackend listing is unrelated to whether a route attaches.

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

An 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.

2-4Implementing a VPC network

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?
