Question 2

Which Agile framework organizes work into fixed-length iterations called sprints, typically 1-4 weeks?

Accepted Answer

Scrum

Answer

Scrum uses time-boxed sprints with defined ceremonies (planning, daily standup, review, retrospective) to deliver incremental value.

Question 3

What is the purpose of a 'Definition of Done' (DoD) in Agile DevOps teams?

Accepted Answer

A shared checklist of criteria that must be met before a work item is considered complete

Answer

The Definition of Done is a shared agreement on all conditions — coding, testing, documentation — that must be satisfied before a story is marked complete.

Question 4

Which DevOps concept involves progressively routing a small percentage of production traffic to a new version before a full rollout?

Accepted Answer

Canary deployment

Answer

A canary deployment sends a small fraction of real traffic to the new version to validate it before gradually increasing the rollout.

Question 5

What does 'infrastructure immutability' mean in modern DevOps practices?

Accepted Answer

Servers are never modified in place; instead, new instances replace old ones

Answer

Immutable infrastructure means that once a server or container is deployed, it is never patched or modified; any change requires deploying a new instance.
