Which of the following YAML snippets correctly defines a ClusterIP service?

AapiVersion: v1 kind: Pod metadata: name: my-service spec: containers: - name: myapp image: nginx

BapiVersion: v1 kind: Service metadata: name: my-service spec: type: NodePort selector: app: myapp ports: - protocol: TCP port: 80 targetPort: 8080

CapiVersion: v1 kind: Service metadata: name: my-service spec: type: ClusterIP selector: app: myapp ports: - protocol: TCP port: 80 targetPort: 8080

DapiVersion: v1 kind: Service metadata: name: my-service spec: type: LoadBalancer selector: app: myapp ports: - protocol: UDP port: 80 targetPort: 8080

Step-by-Step Solution

Solution:

Step 1: Check service type and selector
apiVersion: v1 kind: Service metadata: name: my-service spec: type: ClusterIP selector: app: myapp ports: - protocol: TCP port: 80 targetPort: 8080 uses type: ClusterIP and has a proper selector and ports defined.
Step 2: Validate other options
apiVersion: v1 kind: Service metadata: name: my-service spec: type: NodePort selector: app: myapp ports: - protocol: TCP port: 80 targetPort: 8080 uses NodePort, not ClusterIP. apiVersion: v1 kind: Pod metadata: name: my-service spec: containers: - name: myapp image: nginx is a Pod, not a Service. apiVersion: v1 kind: Service metadata: name: my-service spec: type: LoadBalancer selector: app: myapp ports: - protocol: UDP port: 80 targetPort: 8080 uses type: LoadBalancer, not ClusterIP.
Final Answer:
YAML with type ClusterIP, selector, and TCP port -> Option C
Quick Check:
Correct YAML = apiVersion: v1 kind: Service metadata: name: my-service spec: type: ClusterIP selector: app: myapp ports: - protocol: TCP port: 80 targetPort: 8080 [OK]

Quick Trick: ClusterIP service YAML must specify type: ClusterIP [OK]

Common Mistakes:

Using wrong service type like NodePort
Confusing Pod definition with Service
Omitting service type field
