1. 1

   What is the primary purpose of a Kubernetes Ingress resource?

   A To schedule application containers on worker nodes B To define external HTTP and HTTPS routing rules for Services C To provide persistent storage to Pods
2. 2

   In the diagram, component X watches Ingress resources and configures the traffic-handling proxy. What is component X?

   

   A An Ingress controller B A container runtime C A persistent volume provisioner
3. 3

   Which Kubernetes field normally selects the controller intended to implement an Ingress?

   A spec.controllerSelector B metadata.controllerName C spec.ingressClassName
4. 4

   Which pathType requires the complete request path to match the configured path exactly?

   A Prefix B Exact C ImplementationSpecific
5. 5

   The diagram shows Prefix rules for /api and /api/v1 under the same host. Which backend receives a request for /api/v1/users?

   

   A The backend associated with /api/v1 B The backend associated with /api C Neither backend, because Prefix rules cannot overlap
6. 6

   Which data is normally stored in a Kubernetes TLS Secret used by an Ingress?

   A A cloud access key and secret access key B A username and password for the backend Service C A certificate and its corresponding private key
7. 7

   What does an Ingress default backend handle?

   A Only requests that use HTTP instead of HTTPS B Requests that do not match any configured host or path rule C Only health checks sent by the Kubernetes API server
8. 8

   The diagram shows an HTTPS connection ending at the Ingress proxy, followed by an HTTP connection to the application Service. Where is TLS terminated?

   

   A At the client browser B At the application Pod C At the Ingress proxy
9. 9

   Why can creating an Ingress resource fail to make an application externally reachable?

   A No compatible Ingress controller is installed or running B Every Ingress must directly contain a public IP address in its specification C Ingress resources can route traffic only to databases
10. 10

    The Service behind an Ingress selects three Pods, but one Pod is not ready. Which Pods should normally receive new requests through the Service?

    

    A All three Pods regardless of readiness B Only the two ready Pods C Only the unready Pod until its test succeeds
11. 11

    Under the standard Kubernetes Ingress API, where must a backend Service referenced by an Ingress normally exist?

    A In the kube-system namespace B In any namespace selected by the IngressClass C In the same namespace as the Ingress
12. 12

    The diagram shows two requests entering the same Ingress: store.example.com and admin.example.com. Which feature sends them to different Services?

    

    A Host-based routing rules B Pod anti-affinity C Persistent volume claims
13. 13

    Which HTTP header is commonly used by a reverse proxy to pass the original client IP address to a backend application?

    A Content-Encoding B X-Forwarded-For C Accept-Language
14. 14

    Which HTTP headers are central to establishing a WebSocket protocol upgrade through a reverse proxy?

    A ETag and If-None-Match B Content-Length and Content-Range C Upgrade and Connection
15. 15

    The diagram shows a valid host and path rule leading to a Service with no ready endpoints. What is the most likely cause of the failed response?

    

    A The proxy has no healthy backend endpoint to receive the request B The client failed to match any Ingress host rule C The Ingress automatically deleted the Service
16. 16

    A team wants to send 10% of traffic to a canary release using an Ingress controller's annotations. What portability limitation should they recognize?

    A Annotations are automatically translated identically by every controller B Canary annotations are generally controller-specific rather than portable Ingress behavior C Kubernetes annotations can store only numeric values
