An AKS application loses availability during rolling maintenance because it has one replica and no disruption controls. Which two measures most directly improve survivability? Select 2 answers.

Select all that apply. Every correct option and no extras are required for credit in the app.

A.Run multiple healthy replicas with suitable topology spread
B.Use appropriate disruption budgets and readiness checks with sufficient replacement capacity
C.Keep all durable state only on one pod's local filesystem
D.Increase image tag mutability so nodes always pull an unreviewed latest build
E.Assume Kubernetes control-plane management protects every individual pod

Show the answer and explanation

✓ Correct answers

Run multiple healthy replicas with suitable topology spread
Use appropriate disruption budgets and readiness checks with sufficient replacement capacity

Replica diversity and controlled disruption with readiness and capacity improve maintenance tolerance. Local-only state can lose data, a managed control plane cannot protect a single pod from all failures, and mutable unreviewed images undermine release control. Source guide: PDF page(s) 46.
