Your HTTPRoute is in the 'app' namespace, but the backend service 'payments' is in the 'backend' namespace. You need to route traffic to this cross-namespace service. What must you configure in the HTTPRoute's backendRef to make this work?

Set the 'name' field in the backendRef to 'payments.backend.svc.cluster.local'

Use a Gateway in the 'backend' namespace to route to the service

Set the 'namespace' field in the backendRef to 'backend'

Create the HTTPRoute in the 'backend' namespace instead

You are configuring an HTTPRoute for a canary deployment. You want 90% of traffic to go to the stable service (v1) and 10% to the canary service (v2). Both services are in the same namespace. Which backendRef configuration achieves this traffic split?

Two rules: one matching all traffic to v1, another matching all traffic to v2

Two backendRefs in the same rule: one to v1 with weight 90, one to v2 with weight 10

One backendRef to v1 with weight 100 and another rule to v2 with weight 10

One backendRef to v1 and a second backendRef to v2, both without weights

You have an HTTPRoute that matches hostname 'example.com' and routes to service A. You also have a second HTTPRoute that matches hostname 'example.com' and path prefix '/admin' and routes to service B. Both HTTPRoutes are attached to the same Gateway. A request to 'example.com/admin' is received. Which service will receive the request?

Neither service, because having two HTTPRoutes with overlapping matches is invalid

Service A, because it is the first HTTPRoute created

Both services, because both HTTPRoutes match the request

Service B, because the HTTPRoute with the more specific match (path prefix '/admin') takes precedence

What is the primary purpose of a GatewayClass resource in the Gateway API?

To define the network listeners (ports and protocols) that a Gateway exposes

To define routing rules for HTTP traffic to backend services

To specify the backend services that a Gateway should forward traffic to

To specify the controller that will manage Gateways of this class
