Step-by-Step Solution
Solution:
Step 1: Understand limitations of Deployments
Deployments do not provide stable network IDs or persistent storage, nor control over disruptions.Step 2: Recognize why advanced patterns are needed
StatefulSet and PodDisruptionBudget address these needs for stateful and highly available apps.Final Answer:
Because Deployments do not guarantee stable identities or controlled disruptions needed by some apps -> Option CQuick Check:
Deployments lack stable IDs and disruption control [OK]
Quick Trick: Use advanced patterns for stateful and disruption-sensitive apps [OK]
