Which Kubernetes feature helps check if your app is running correctly in production?
AConfigMap
BPersistent Volume
CNamespace
DLiveness Probe
Step-by-Step Solution
Solution:
  1. Step 1: Identify health check features in Kubernetes

    Kubernetes uses probes to check app health: liveness and readiness probes.
  2. Step 2: Match feature to checking if app is running

    Liveness probe checks if the app is alive and restarts it if not.
  3. Final Answer:

    Liveness Probe -> Option D
  4. Quick Check:

    Liveness Probe = app health check [OK]
Quick Trick: Liveness probe checks if app is alive, readiness probe checks if ready [OK]
Common Mistakes:
  • Confusing ConfigMap with health checks
  • Thinking Namespace controls app health
  • Assuming Persistent Volume monitors app status
