DOL DevOps Principles 4

Question 1

A team has a lead time for changes of 6 months. According to DORA benchmarks, this classifies them as:

Accepted Answer

Low performers

Answer

DORA research classifies teams with lead times greater than six months as low performers, indicating significant process inefficiencies.

Question 2

What is the primary DevOps rationale for small, frequent commits over large, infrequent ones?

Accepted Answer

They reduce integration complexity and make failures easier to isolate

Answer

Small commits limit the scope of changes, making merge conflicts, failures, and root cause analysis significantly easier to handle.

Question 3

Which concept describes the practice of ensuring infrastructure configuration is always restored to a known state, ignoring any manual changes made directly?

Accepted Answer

Immutable infrastructure

Answer

Immutable infrastructure means servers are never modified in place; instead, new instances with correct configuration replace old ones, preventing configuration drift.

Question 4

A DevOps leader is asked to justify DevOps adoption to the CFO. Which argument is MOST aligned with DevOps business outcomes research?

Accepted Answer

High-performing DevOps teams deploy more frequently with lower failure rates, improving both speed and stability

Answer

DORA research consistently shows elite DevOps teams achieve higher deployment frequency AND lower change failure rates, proving speed and stability are not trade-offs.

Question 5

What is the purpose of a 'deployment pipeline' in DevOps?

Accepted Answer

An automated sequence of stages that validates and delivers software to production

Answer

A deployment pipeline automates build, test, and release stages, providing fast feedback and consistent delivery from commit to production.
