You want to implement a progressive delivery strategy that automatically rolls back if error rates exceed 5%. Which Kubernetes tool or feature best supports this?
AKubernetes Horizontal Pod Autoscaler
BPersistentVolumeClaim with backup snapshots
CConfigMap with error thresholds
DService Mesh with automated traffic shifting and monitoring
Step-by-Step Solution
Solution:
  1. Step 1: Identify tools for automated rollback

    Service Meshes like Istio support traffic shifting and monitoring with automatic rollback on errors.
  2. Step 2: Eliminate unrelated options

    Autoscaler manages scaling, ConfigMap stores config but no automation, PVC is storage only.
  3. Final Answer:

    Service Mesh with automated traffic shifting and monitoring -> Option D
  4. Quick Check:

    Auto rollback needs Service Mesh monitoring [OK]
Quick Trick: Use Service Mesh for auto rollback on errors [OK]
Common Mistakes:
  • Confusing autoscaling with rollback
  • Expecting ConfigMap to automate rollback
  • Thinking storage snapshots handle rollback
