Which approach improves pipeline performance by reducing the amount of data transferred between jobs?

Using a single job with multiple steps

Using pipeline artifacts to pass files between jobs

Using multiple stages with separate agents

Your pipeline uses a large number of hosted agents for a short period, and the cost is high. You want to reduce cost while maintaining performance. What should you do?

Reduce the number of parallel jobs to lower the number of agents used.

Use self-hosted agents that are always on.

Use a self-hosted agent pool with auto-scaling that scales down when idle.

Use a single agent for all jobs to minimize cost.

Which practice minimizes pipeline time by avoiding repeated execution of unchanged steps?

Running all tests in a single step

Increasing the pipeline timeout

Caching dependencies and build outputs

Your team has a limited number of parallel pipeline jobs available in their Azure DevOps subscription. The team wants to ensure that the most important production deployment pipeline always runs immediately, while other pipelines can wait. What should you configure?

Schedule the production pipeline to run at a specific time to avoid contention.

Reduce the number of parallel jobs for the production pipeline to save resources.

Set a higher concurrency limit for the production pipeline than for other pipelines.

Use a separate agent pool for the production pipeline and reserve agents for that pool.

Your organization runs a large number of CI pipelines on Microsoft-hosted agents. The finance team wants to reduce the cost of the agents, but the development team wants to maintain fast feedback times. The pipelines are mostly short builds that run on every commit. What is the most effective way to balance cost and feedback time?

Move all pipelines to self-hosted agents that are always on.

Reduce the number of parallel jobs to the minimum required for the team's workflow.

Consolidate multiple pipelines into a single pipeline that runs all builds sequentially.

Increase the pipeline timeout to allow more time for builds.
