Step-by-Step Solution
Solution:
Step 1: Identify correct field names and types for backups and scaling
Backups require 'backups' with enabled and schedule fields; autoscaling needs enabled, minReplicas, maxReplicas.Step 2: Compare options for correctness
spec: replicas: 3 version: "5.0" backups: enabled: true schedule: "0 1 * * *" autoscaling: enabled: true minReplicas: 2 maxReplicas: 5 uses correct field names, proper YAML structure, and valid values for version and schedule.Final Answer:
spec: replicas: 3 version: "5.0" backups: enabled: true schedule: "0 1 * * *" autoscaling: enabled: true minReplicas: 2 maxReplicas: 5 -> Option AQuick Check:
Correct fields and values enable features [OK]
Quick Trick: Use exact field names and valid cron schedules [OK]
Common Mistakes:
- Using 'backup' instead of 'backups'
- Incorrect autoscaling field names
- Setting enabled false disables features
