DAC DevOps & Continuous Delivery 2

Question 1

In Disciplined Agile, what is the primary goal of a deployment pipeline?

Accepted Answer

To provide a repeatable, reliable process for delivering software to production

Answer

A deployment pipeline automates and standardizes the path from code commit to production, ensuring reliability and repeatability.

Question 2

Which DevOps metric measures the average time from code commit to running in production?

Accepted Answer

Lead Time for Changes

Answer

Lead Time for Changes tracks the elapsed time from when a developer commits code until that change is deployed to production.

Question 3

What does 'shift-left testing' mean in a Continuous Delivery context?

Accepted Answer

Performing testing activities earlier in the development lifecycle

Answer

Shift-left testing moves quality activities earlier in the pipeline so defects are caught closer to their introduction.

Question 4

In a DA context, what is a 'feature toggle' primarily used for in Continuous Delivery?

Accepted Answer

Decoupling deployment from release so features can be deployed but not yet activated

Answer

Feature toggles allow code to be deployed to production while keeping new features hidden until deliberately activated.

Question 5

Which practice best supports 'continuous integration' in a DevOps environment?

Accepted Answer

Developers integrating their work frequently, at least daily, with automated builds and tests

Answer

Continuous Integration requires frequent merges to mainline with automated validation to detect integration problems early.
