Question 1

What are the two ways to pass data between jobs? (Choose two.)

AUse the copy action with restore parameter to restore the data from the cache

BUse the copy action to save the data that should be passed in the artifacts folder.

CUse the copy action with cache parameter to cache the data

DUse data storage.

EUse job outputs

FUse artifact storage.

Answer : E, F

Job outputs are used to pass data from one job to another in a workflow. A job can produce output values (like variables or files), which can be referenced by subsequent jobs using the needs keyword and ${{ steps.step_id.outputs.output_name }} syntax.

Artifact storage allows data (such as files or results) to be saved by a job and then retrieved by another job in a later step. This is commonly used for passing large amounts of data or files between jobs.

Question 2

Which of the following is the best way for an enterprise to prevent certain marketplace actions from running?

ACreate a list of the actions that are restricted from being used as an enterprise policy. Every other action can be run.

BIt is not possible; if an action is in the marketplace, its use cannot be restricted.

CCreate a list that is maintained as a . yml file in a . github repository specified in the enterprise. Only these actions can be run.

DCreate a list of the actions that are allowed to run as an enterprise policy. Only these actions can be run.

Answer : D

The best way for an enterprise to control which GitHub Actions run is by creating a list of approved actions as an enterprise policy. This approach restricts workflows to only use the actions that are explicitly allowed, ensuring security and compliance within the organization.

Question 3

As a developer, you are designing a workflow and need to communicate with the runner machine to set environment variables, output values used by other actions, add debug messages to the output logs, and other tasks. Which of the following options should you use?

Aenvironment variables

Bworkflow commands

Cself-hosted runners

Denable debug logging
E composite run step

Answer : B

Workflow commands are special commands that allow you to interact with the runner, set environment variables, output values, add debug messages, and perform other tasks within the workflow. These commands are used to modify the environment or influence the behavior of the GitHub Actions runner.

Question 4

As a developer, you are optimizing a GitHub workflow that uses and produces many different files. You need to determine when to use caching versus workflow artifacts. Which two statements are true? (Choose two.)

AUse caching when reusing files that change rarely between jobs or workflow runs.

BUse artifacts when referencing files produced by a job after a workflow has ended.

CUse caching to store cache entries for up to 30 days between accesses.

DUse artifacts to access the GitHub Package Registry and download a package for a workflow

Answer : A, B

Caching is ideal for files that change rarely, such as dependencies or build outputs, as it speeds up subsequent workflow runs by reusing previously cached files instead of re-downloading or rebuilding them.

Artifacts are used for persisting files produced during a job that need to be used in later jobs or after the workflow has ended, allowing them to be downloaded or referenced later.

Question 5

You need to make a script to retrieve workflow run logs via the API. Which is the correct API to download a workflow run log?

APOST /repos/:owner/:repo/actions/runs/:run_id

BGET /repos/:owner/:repo/actions/artifacts/logs

CGET /repos/:owner/:repo/actions/runs/:run_id/logs

DPOST /repos/:owner/:repo/actions/runs/:run_id/logs

Answer : C

The GET /repos/:owner/:repo/actions/runs/:run_id/logs API endpoint is used to retrieve the logs of a specific workflow run identified by run_id. This is the correct method for downloading logs from a workflow run.

Question 6

GitHub-hosted runners support which capabilities? (Choose two.)

Aautomatic patching of both the runner and the underlying OS

Bautomatic file-system caching between workflow runs

Csupport for Linux, Windows, and mac

Dsupport for a variety of Linux variations including CentOS, Fedora, and Debian

Erequiring a payment mechanism (e.g., credit card) to use for private repositories

Answer : C, D

GitHub-hosted runners automatically handle patching, meaning they will be kept up to date with the latest security updates and software patches for both the runner environment and the underlying operating system.

GitHub-hosted runners support Linux, Windows, and macOS, giving you flexibility to run workflows on different operating systems without needing to manage your own self-hosted runners.

Question 7

You need to create new workflows to deploy to an unfamiliar cloud provider. What is the fastest and safest way to begin?

ACreate a custom action to wrap the cloud provider's CLI.

BSearch GitHub Marketplace for verified actions published by the cloud provider.

CUse the actions/jenkins-plugin action to utilize an existing Jenkins plugin for the cloud provider.

DSearch GitHub Marketplace for actions created by GitHub.

EDownload the CLI for the cloud provider and review the associated documentation.

Answer : B

Searching the GitHub Marketplace for verified actions published by the cloud provider is the quickest and safest approach. Many cloud providers offer verified GitHub Actions that are maintained and optimized to interact with their services. These actions typically come with the correct configurations and best practices, allowing you to get started quickly without reinventing the wheel.
