   What is the primary purpose of CI pipeline orchestration?

   • ATo automatically fix code errors before they reach the build stage
   • BTo store compiled artifacts for later deployment
   • CTo define the sequence and dependencies of tasks so they execute in the correct order
   • DTo replace the need for version control systems

   A large monorepo contains several independent services. The CI pipeline is configured to build and test every service on every commit, which takes over an hour. The team wants to reduce pipeline time while still ensuring that changes to a service are tested before merge. They are considering implementing path-based triggers. What is the most important consideration when implementing this change?

   • AConfigure the pipeline to run all services in parallel to reduce the total time.
   • BEnsure that changes to shared libraries trigger the builds of all services that depend on them.
   • CIncrease the number of build agents to handle the load from more frequent builds.
   • DMove all services into separate repositories to avoid the monorepo complexity.

   What is the purpose of a lock file in dependency management?

   • ATo prevent multiple developers from editing the same file
   • BTo pin the exact versions of dependencies used in a build
   • CTo encrypt dependencies before they are stored
   • DTo automatically resolve dependency conflicts

   A CI pipeline for a C++ project uses CMake and a third-party library that is built from source. The library build takes 20 minutes. The team wants to speed up the pipeline. They are considering caching the built library. What is the most important consideration for the cache to be effective?

   • AThe cache must be stored on the same machine that runs the build.
   • BThe cache key must include the source version of the library and the compiler version and build configuration.
   • CThe cache must be compressed to reduce storage costs.
   • DThe cache must be cleared after every build to ensure fresh artifacts.

   A CI pipeline for a Node.js application runs `npm install` in the build stage. The team wants to ensure that the exact same versions of dependencies are installed every time the pipeline runs, even if new versions are published to the npm registry. What is the most reliable way to achieve this?

   • ASet the `NPM_CONFIG_REGISTRY` environment variable to a private registry that hosts only the approved versions.
   • BUse `npm install --save-exact` in the build stage to pin all dependencies to exact versions.
   • CCommit the `package-lock.json` file to the repository and run `npm ci` instead of `npm install`.
   • DDelete the `node_modules` folder before running `npm install` to force a fresh download.
