Kubernetes - Ingress

Given this Ingress rule snippet, what service will receive traffic for host 'app.example.com'?

spec:
  rules:
  - host: app.example.com
    http:
      paths:
      - path: /app
        pathType: Prefix
        backend:
          service:
            name: app-service
            port:
              number: 8080
      - path: /
        pathType: Prefix
        backend:
          service:
            name: default-service
            port:
              number: 80

ATraffic to app.example.com with path starting /app goes to app-service; others go to default-service.

BTraffic to app.example.com is rejected because of duplicate host rules.

CTraffic to app.example.com goes only to default-service on port 80.

DAll traffic to app.example.com goes to app-service on port 8080.

Step-by-Step Solution

Solution:

Step 1: Analyze the Ingress rules for host 'app.example.com'
The rule for host 'app.example.com' has two paths: '/app' and '/'.
Step 2: Understand path matching priority
Requests with path starting '/app' go to 'app-service' on port 8080; all other paths go to 'default-service' on port 80.
Final Answer:
Traffic to app.example.com with path starting /app goes to app-service; others go to default-service. -> Option A
Quick Check:
Host + path routing = Traffic to app.example.com with path starting /app goes to app-service; others go to default-service. [OK]

Quick Trick: Check host and path rules separately to find matching service [OK]

Common Mistakes:

Assuming all traffic goes to first service listed
Thinking duplicate hosts cause rejection
Ignoring path prefixes in routing
