Question 1

Which practice ensures that code remains in a continuously deployable state within an agile team?

Accepted Answer

Continuous Delivery (CD) with automated build, test, and deployment pipelines

Answer

Quarterly release planning with manual integration testing

Answer

Manual build processes triggered by the release manager

Answer

Long-lived feature branches merged only at the end of each sprint

Question 2

What is the purpose of an architectural spike in Disciplined Agile?

Accepted Answer

To explore a technical uncertainty or risk through a time-boxed investigation

Answer

To document the current system architecture for stakeholders

Answer

To deliver a fully designed feature before committing to implementation

Answer

To replace the architecture owner's decisions with team consensus voting

Question 3

What does 'technical excellence' mean in the Disciplined Agile context?

Accepted Answer

Maintaining high code quality, automated testing, and sound architectural practices to enable sustainable delivery

Answer

Using the latest technology stack regardless of the project's specific needs

Answer

Achieving 100% automated test coverage on every sprint without exception

Answer

Following strict waterfall-style documentation standards for all technical decisions

Question 4

Which practice in Disciplined Agile most directly reduces the cost of future code changes over time?

Accepted Answer

Continuous refactoring and clean code practices

Answer

Comprehensive upfront documentation of all requirements

Answer

Freezing requirements as early as possible in the project

Question 5

What does collective code ownership mean in Disciplined Agile teams?

Accepted Answer

Any team member can modify any part of the codebase, with shared responsibility for overall quality

Answer

Only the architecture owner is authorized to modify the production codebase

Answer

Code ownership is formally assigned per feature to individual named developers

Answer

Question 6

In Disciplined Agile, when should major architecture decisions ideally be made?

Accepted Answer

As late as responsibly possible, when sufficient information is available to make sound decisions

Answer

All at once during project initiation before any development starts

Answer

Only by external enterprise architects who are independent of the delivery team

Answer

Only after all requirements have been formally approved and frozen

Question 7

What is the primary benefit of automated testing suites in Disciplined Agile teams?

Accepted Answer

Providing fast feedback on code changes and significantly reducing regression risk

Answer

Eliminating the need for manual exploratory testing entirely

Answer

Satisfying all external compliance requirements without any manual verification

Answer

Replacing the need for an architecture owner role on the team
