An Ingress is configured with TLS, but clients receive a certificate warning. What is a common cause?

The Ingress controller is not running.

The Ingress resource does not have a host field.

The TLS secret does not contain a valid certificate for the hostname.

Which of the following is true about Ingress resources?

They replace the need for Services entirely.

They can route traffic based on the requested hostname and URL path.

They can expose any TCP/UDP service, not just HTTP/S.

They are automatically applied without any controller.

Which kubectl command creates a Service to expose a deployment named 'web' on port 80, targeting container port 8080?

kubectl create service deployment web --port=80 --target-port=8080

kubectl run web --port=80 --target-port=8080

kubectl apply -f web-service.yaml --port=80 --target-port=8080

kubectl expose deployment web --port=80 --target-port=8080

An administrator created an Ingress resource to expose a Service. The Ingress controller is running, but requests to the Ingress return a 404 Not Found error. The Ingress YAML is shown below: ```yaml apiVersion: networking.k8s.io/v1 kind: Ingress metadata: name: example-ingress spec: rules: - host: example.com http: paths: - path: / pathType: Prefix backend: service: name: web-svc port: number: 80 ``` The Service 'web-svc' exists and has endpoints. What is the most likely cause of the 404 error?

The host 'example.com' does not resolve to the Ingress controller's IP.

The Ingress controller is not configured with the correct class.

The Service port is set to 80, but the pods listen on 8080.

The Service selector does not match the pods.
