A team wants to use monitoring and observability to drive continuous improvement of their software quality. They have deployed a new version and want to know if it is performing as expected. Which metric is most useful for detecting a regression in user experience?

Application error rate and response time.

CPU utilization of the application server.

Number of test cases executed in CI.

Number of lines of code changed.

What is the fundamental concept of Infrastructure as Code (IaC)?

Creating a single, large script that sets up the entire production environment from scratch.

Manually configuring servers and environments using a web console to ensure precise control.

Using a cloud provider's proprietary API to create resources without any version control.

Managing and provisioning infrastructure through machine-readable definition files, rather than physical hardware configuration or interactive configuration tools.

A team wants to improve the flow of feedback between development and operations. They currently have separate teams that rarely communicate. Which practice best embodies the DevOps principle of sharing?

Use a ticketing system for all communication between teams.

Hold regular joint meetings where developers and operations share metrics and lessons learned.

Have developers monitor production systems on a rotating basis.

Create a shared documentation repository for all teams.

A team is struggling with a 'blame culture' where testers are held responsible for defects that escape to production. They want to adopt a DevOps culture. Which change is most aligned with DevOps principles?

Require testers to sign off on every release to ensure accountability.

Implement a reward system for testers who find the most defects.

Create a separate quality assurance team to audit all releases.

Establish a blameless post-incident review process that focuses on system and process improvements.

A team is experiencing frequent integration conflicts and defects that are found late. They want to adopt continuous integration to detect issues earlier. Which practice is most essential to implement?

Run a full regression suite only on the release branch before deployment.

Create feature branches that are merged only at the end of the release cycle.

Integrate code changes into a shared mainline at least daily, with automated builds and tests.

Use a code review tool that automatically merges changes without running tests.
