A team wants to configure GitLab Group Runners for multiple projects but needs to ensure that only specific types of jobs run on them while other jobs should execute on shared GitLab-hosted runners. What is the best way to achieve this?

You are managing a complex GitLab CI/CD pipeline for a project that has multiple stages including build, test, and deploy. The build stage must compile the code, the test stage should run unit tests, and the deploy stage should push the code to a staging server. However, the deploy stage should only run if the build and test stages are successful. How can you ensure that the deploy stage only runs after the successful completion of the build and test stages?

You are working on a project in GitLab that involves multiple environments (development, staging, production). Each environment requires different configurations and credentials. Recently, you’ve observed that the deployment to the production environment sometimes fails due to incorrect configurations being used. Which approach is best to ensure that each environment gets the correct configurations and credentials during deployment?

Your team is working on a GitLab project that handles sensitive user data. To prevent accidental exposure of secrets like API keys and passwords, you need to enable Secret Detection in your CI/CD pipeline. Which of the following steps is NOT required to set up Secret Detection in GitLab?

You are responsible for a CI/CD pipeline that must deploy a complex application composed of multiple services, each with its own repository. You need to ensure that the deployment process only proceeds if the builds and tests for all services are successful. How can you orchestrate this in GitLab?
