A team has a workflow that runs on every push to any branch. Many pushes are small documentation changes that don't require the full build and test pipeline. The team wants to reduce Actions usage costs. What should they do?

Increase the timeout-minutes for the workflow.

Add a path filter to the workflow so it only runs when relevant source files change.

Use a larger runner to finish faster.

Set concurrency to cancel in-progress runs.

What is the effect of setting a shorter artifact retention period in a GitHub repository?

It has no effect on storage costs

It increases the storage cost because artifacts are kept longer

It reduces storage costs but may make artifacts unavailable sooner

It makes artifacts available for a longer time

Which of the following is a cost optimization technique for GitHub Actions?

Disabling caching to avoid storage costs

Using concurrency control to cancel redundant runs

Running workflows on larger runners to finish faster

Increasing the number of jobs in a workflow

A team's CI workflow builds a .NET solution and runs tests. The workflow currently takes 12 minutes per run because it restores NuGet packages from the network on every run. The team wants to reduce runtime and cost without changing the test suite. Which approach should they implement?

Set a concurrency limit on the workflow to prevent multiple runs from executing at the same time.

Add a caching step that keys on the packages.lock.json file and caches the ~/.nuget/packages directory.

Increase the number of jobs in the workflow so that build and test run in parallel.

Use a larger runner type with more CPU and memory.
