Question 1

What is the primary use case for a DaemonSet in Kubernetes?

Accepted Answer

Ensuring exactly one copy of a Pod runs on every (or selected) node

Answer

A DaemonSet guarantees that a Pod replica runs on each eligible node, making it ideal for node-level agents like log collectors or monitoring daemons.

Question 2

Which workload type provides stable network identities and ordered, graceful deployment for stateful applications?

Accepted Answer

StatefulSet

Answer

A StatefulSet gives each Pod a persistent, stable hostname and ordinal index, and manages ordered startup and shutdown for stateful apps like databases.

Question 3

What Kubernetes object should you use to run a task that executes to completion and then stops?

Accepted Answer

Job

Answer

A Job creates one or more Pods to run a task to completion, tracks successes, and stops creating new Pods once the desired completions are reached.

Question 4

In a StatefulSet, what naming convention are Pod identities given?

Accepted Answer

Sequential ordinal suffixes (e.g., web-0, web-1, web-2)

Answer

StatefulSet Pods receive names combining the StatefulSet name and an ordinal index (0, 1, 2...), providing stable, predictable identities across restarts.

Question 5

What happens to a Job's completed Pods by default after the Job finishes?

Accepted Answer

They remain in Completed state so their logs can be inspected

Answer

Completed Pods from a Job are retained in a Completed state by default, allowing administrators to retrieve logs, until the Job or Pods are manually deleted.
