A workflow runs a matrix with `os: [ubuntu-latest, macos-latest]` and `python: [3.8, 3.9, 3.10]`. The run fails for all combinations with `python: 3.10`, but succeeds for all others. What is the most likely common cause of the failures?

The workflow file has a syntax error that only affects certain combinations.

The `ubuntu-latest` runner is out of disk space.

The `macos-latest` runner has a hardware issue.

The Python 3.10 environment has a dependency that is not compatible with the code.

A workflow with a matrix strategy has 4 jobs, and only `build (ubuntu-latest, 18)` failed. The developer wants to rerun only this failed job without rerunning the other 3 jobs. What is the correct approach?

In the Actions tab, open the failed run, select the failed job, and click "Re-run jobs"

Push an empty commit to the repository to trigger a new run

Modify the workflow file to remove the other matrix values and re-run

Re-run the entire workflow from the run summary page

A workflow run failed, and the developer sees the following in the job log: ``` Run npm test npm ERR! code ELIFECYCLE npm ERR! errno 1 npm ERR! test: `jest` ``` What is the most likely root cause of the failure?

The workflow file has a YAML syntax error

The `jest` package is not listed in `package.json`

The `npm test` command exited with a non-zero exit code, indicating test failures

The `npm` package manager is not installed on the runner

A workflow is configured with a `schedule` trigger using cron syntax: `cron: '0 2 * * *'`. When will this workflow run?

Twice a day at 2:00 AM and 2:00 PM UTC

Every hour at 2 minutes past the hour
