A team is developing a microservices-based application. They want to ensure that the services work correctly together before deployment, but they also want to keep the CI pipeline fast. Which testing strategy is most appropriate?

Run only manual testing after deployment

Run unit tests for each service in CI and run integration tests in a separate staging pipeline

Skip unit tests and only run integration tests before release

Run all integration tests in CI for every commit

In Service-Oriented Architecture (SOA), what does 'service reusability' mean?

A service is rebuilt from source code each time it is called.

A service must be redeployed after every use to ensure freshness.

A service can only be used by one application at a time.

A service can be used by multiple applications or business processes without modification.

A development team is using a version control system. They want to ensure that every change is reviewed by at least one other developer before being merged into the main branch. They also want to maintain a clean history. Which workflow best supports this?

Use version control only for releases, not for daily development

Feature branches with pull requests and mandatory code review before merge

Direct commits to the main branch with no review

A single shared branch where all developers commit directly

A project manager is choosing a development lifecycle for a system with strict regulatory compliance requirements. The system must undergo formal security review at each phase, and requirements are fully defined. However, the team wants to incorporate user feedback during development. Which approach best balances these needs?

Agile without any formal security reviews

Waterfall for the entire project with a single security review at the end

Agile with security reviews integrated into each sprint and regular stakeholder feedback

Waterfall with a formal security review at each phase and no changes after requirements are signed off

Part of the Application Development and Security Fundamentals domain, which makes up ~20% of our current practice bank. EC-Council does not publish an official question count, but from its 120-minute exam (~50–80 total, ~10–16 in this domain), expect 2–3 from this objective — we provide 62 practice questions to prepare you well beyond it.
