NEW QUESTION # 38
As a developer, your Actions workflow often reuses the same outputs or downloaded dependencies from one run to another. To cache dependencies for a job, you are using the GitHub cache action. Which input parameters are required for this action? (Choose two.)
- A. restore-keys: the copy action key used with cache parameter to cache the data
- B. ref: the ref name of the branch to access and restore a cache created
- C. dependency: the name and version of a package to cache or restore
- D. cache-hit: the copy action key used with restore parameter to restore the data from the cache
- E. path: the file path on the runner to cache or restore
- F. key: the key created when saving a cache and the key used to search for a cache
Answer: E,F
Explanation:
The key is required because it uniquely identifies the cache. It is used to store and retrieve cached data. When creating or restoring a cache, you need to define a key that will be used to identify the cache.
The path is the file path on the runner that you want to cache. This is where the cached files or dependencies are located and should be specified to tell GitHub where to store or retrieve the cache from.
NEW QUESTION # 39
What is the smallest scope for an environment variable?
- A. a job
- B. the workflow env mapping
- C. a step
- D. the workflow settings
Answer: C
Explanation:
The smallest scope for an environment variable is within astep. Environment variables defined within a step are only accessible to that particular step, which makes it the smallest scope for a variable in a GitHub Actions workflow.
NEW QUESTION # 40

The correct minimal syntax for declaring an output in GitHub Actions is by using thefookey underoutputs, and associating it with avalue(in this case,Some value). This is the simplest form to define an output in a workflow or action.
NEW QUESTION # 42
Which scopes are available to define custom environment variables within a workflow file? (Choose three.)
- A. the contents of a job within a workflow, by using jobs.<job_id>.env
- B. within the run attribute of a job step
- C. all jobs being run on a single Actions runner, by using runner.env at the top of the workflow file
- D. a specific step within a job, by using jobs.<job_id>.steps[*].env
- E. the entire stage, by using env at the top of the defined build stage
- F. the entire workflow, by using env at the top level of the workflow file
Answer: B,D,F
Explanation:
You can define environment variables for the entire workflow by using the env key at the top level of the workflow file. These environment variables will be available to all jobs and steps within the workflow.
Environment variables can also be set within the run attribute of a job step, and these variables will be scoped only to that specific step.
You can set environment variables for specific steps within a job by using jobs.<job_id>.steps[*].env, which allows you to define variables that will only be available to that step.
NEW QUESTION # 43

NEW QUESTION # 44
As a developer, you need to use GitHub Actions to deploy a microservice that requires runtime access to a secure token. This token is used by a variety of other microservices managed by different teams in different repos. To minimize management overhead and ensure the token is secure, which mechanisms should you use to store and access the token? (Choose two.)
- A. Store the token in a configuration file in a private repository. Use GitHub Actions to deploy the configuration file to the runtime environment.
- B. Store the token as a GitHub encrypted secret in the same repo as the code. Create a reusable custom GitHub Action to access the token by the microservice at runtime.
- C. Use a corporate non-GitHub secret store (e.g., HashiCorp Vault) to store the token. During deployment, use GitHub Actions to store the secret in an environment variable that can be accessed at runtime.
- D. Store the token as an organizational-level encrypted secret in GitHub. During deployment, use GitHub Actions to store the secret in an environment variable that can be accessed at runtime.
- E. Store the token as a GitHub encrypted secret in the same repo as the code. During deployment, use GitHub Actions to store the secret in an environment variable that can be accessed at runtime.
Answer: C,D
Explanation:
Using a corporate secret store like HashiCorp Vault provides a secure, centralized location for sensitive information. GitHub Actions can then retrieve and store the token securely during deployment by setting it as an environment variable, ensuring the token remains secure and accessible at runtime.
Storing the token as an organizational-level encrypted secret in GitHub ensures it is accessible across multiple repositories, minimizing management overhead. GitHub Actions can then use this secret during deployment by setting it as an environment variable, allowing the microservice to access it securely at runtime.
NEW QUESTION # 45
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?
- A. GET /repos/:owner/:repo/actions/artifacts/logs
- B. POST /repos/:owner/:repo/actions/runs/:run_id
- C. GET /repos/:owner/:repo/actions/runs/:run_id/logs
- D. POST /repos/:owner/:repo/actions/runs/:run_id/logs
Answer: C
Explanation:
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.
NEW QUESTION # 46

- A. enable debug logging
E composite run step - B. self-hosted runners
- C. environment variables
- D. workflow commands
Answer: D
Explanation:
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.
NEW QUESTION # 47
What are the two types of environment protection rules you can configure? (Choose two.)
- A. wait timer
- B. required reviewers
- C. branch protections
- D. artifact storage
Answer: A,B
Explanation:
Required reviewers is a protection rule where you can specify that certain individuals or teams must review and approve the workflow run before it can proceed. This is used to enforce approvals before certain steps or environments are accessed.
Wait timer is a protection rule that introduces a delay before a workflow can proceed to the next stage. This is useful for adding time-based constraints to the deployment process or ensuring that certain conditions are met before a workflow continues.
NEW QUESTION # 48

- A. support for a variety of Linux variations including CentOS, Fedora, and Debian
- B. requiring a payment mechanism (e.g., credit card) to use for private repositories
- C. support for Linux, Windows, and mac
- D. automatic patching of both the runner and the underlying OS
- E. automatic file-system caching between workflow runs
Answer: A,C
Explanation:
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.
NEW QUESTION # 50
As a developer, your self-hosted runner sometimes looses connection while running jobs. How should you troubleshoot the issue affecting your self-hosted runner?
- A. Set the DEBUG environment variable to true before starting the self-hosted runner to produce more verbose console output.
- B. Access the self-hosted runner's installation directory and look for log files in the _diag folder.
- C. Start the self-hosted runner with the --debug flag to produce more verbose console output.
- D. Locate the self-hosted runner in your repository's settings page and download its log archive.
Answer: B
Explanation:
When troubleshooting a self-hosted runner, you can access the_diagfolder located in the self-hosted runner's installation directory. This folder contains diagnostic logs that can help you identify the root cause of issues, such as connection problems.
NEW QUESTION # 51
Which syntax correctly accesses a job output (output1) of an upstream job (job1) from a dependent job within a workflow?
- A. ${{job1.outputs.output1}}
- B. ${{depends.job1.output1}}
- C. ${{needs.job1.output1}}
- D. ${{needs.job1.outputs.output1}}
Answer: D
Explanation:
Theneedscontext is used to reference the outputs of jobs that are dependencies of the current job. In this case, needs.job1.outputs.output1correctly accesses the output ofoutput1from the jobjob1in the dependent job.
NEW QUESTION # 52
Disabling a workflow allows you to stop a workflow from being triggered without having to delete the file from the repo. In which scenarios would temporarily disabling a workflow be most useful? (Choose two.)
- A. A workflow sends requests to a service that is down.
- B. A workflow needs to be changed from running on a schedule to a manual trigger
- C. A runner needs to have diagnostic logging enabled.
- D. A workflow error produces too many, or wrong, requests, impacting external services negatively.
- E. A workflow is configured to run on self-hosted runners
Answer: A,D
Explanation:
If a workflow depends on an external service that is down, disabling the workflow temporarily will prevent it from running and sending requests to the service, thus avoiding failed requests or unnecessary retries.
If a workflow is causing a negative impact on external services by generating too many requests or incorrect data due to a bug, temporarily disabling the workflow will stop this behavior while the issue is fixed.
NEW QUESTION # 53
Which workflow command would output the debug message "action successfully debugged"?
- A. echo "debug-action successfully debugged"
- B. echo :debug::message=action successfully debugged"
- C. echo ":debug:action successfully debugged:"
- D. echo "::debug::action successfully debugged"
Answer: D
Explanation:
The ::debug:: syntax is used to output debug messages in GitHub Actions workflows. This command will print the message "action successfully debugged" in the debug logs when the workflow runs.
NEW QUESTION # 54
As a developer, you are using a Docker container action in your workflow. What is required for the action to run successfully?
- A. The action must be published to the GitHub Marketplace.
- B. The job env must be set to a Linux environment.
- C. The referenced action must be hosted on Docker Hub.
- D. The job runs-on must specify a Linux machine with Docker installed.
Answer: D
Explanation:
For a Docker container action to run in a GitHub Actions workflow, the runner must have Docker installed.
The runs-on attribute of the job should specify an environment that supports Docker, typically a Linux environment (e.g., ubuntu-latest), since Docker is widely supported and commonly used in Linux-based environments.
NEW QUESTION # 55
How many jobs will result from the following matrix configuration?
- A. 6 jobs
- B. 4 jobs
- C. 3 jobs
- D. 5 jobs
Answer: A
Explanation:
The matrix configuration specifies two variables: color and animal. The color variable has 2 values (green and pink), and the animal variable has 2 values (owl and magpie). This would result in 4 combinations (2 color values × 2 animal values). Additionally, the include section introduces two more combinations (color: blue and animal: owl; color: pink and animal: magpie).
NEW QUESTION # 56
As a developer, you have a 10-MB data set that is required in a specific workflow. Which steps should you perform so the dataset is stored encrypted and can be decrypted during the workflow? (Choose three.)
- A. Store the encryption keys in a GitHub encrypted secret.
- B. Commit the encrypted dataset to the same repository as the workflow
- C. Store the dataset in a GitHub encrypted secret.
- D. Compress the dataset
- E. Leverage the actions/download-secret action in the workflow.
- F. Create a GitHub encrypted secret with the Large object option selected and upload the dataset.
- G. Encrypt the dataset.

Explanation:
First, the dataset should be encrypted before being stored. This ensures that the data is protected when stored in a repository.
The encrypted dataset can be stored in a GitHub secret, ensuring it is securely kept and not exposed publicly.
The encryption key needed to decrypt the dataset should also be stored in a GitHub secret to maintain security during the workflow, allowing access only when needed.
NEW QUESTION # 57
As a developer, how can you identify a Docker container action on GitHub?
- A. The action's repository name includes the keyword "Docker."
- B. The action.yml metadata file references a Dockerfile file.
- C. The action's repository includes @actions/core in the root directory.
- D. The action.yml metadata file has the runs.using value set to Docker.
Answer: D
Explanation:
In a Docker container action, theaction.ymlfile includes theruns.usingfield, which is set todockerto specify that the action runs inside a Docker container. This is the key indicator that the action is a Docker container action.
NEW QUESTION # 58
As a DevOps engineer, you are trying to leverage an organization secret in a repo. The value received in the workflow is not the same as that set in the secret. What is the most likely reason for the difference?
- A. The Encrypt Secret setting was not configured for the secret.
- B. The Codespace secret doesn't match the expected value.
- C. There is a different value specified at the enterprise level.
- D. There is a different value specified at the rego level.
- E. There is a different value specified at the workflow level.
Answer: D
Explanation:
GitHub secrets are defined at different levels: organization, repository, and sometimes at the workflow level.
If a secret is defined at both the organization level and the repository level, the repository-level secret will take precedence. So, if the value of the secret differs between these levels, the workflow will use the value from the repository level instead of the organization level.
NEW QUESTION # 59
When reviewing an action for use, what file defines its available inputs and outputs?
- A. action.yml
- B. defaults.json
- C. inputs.yml
- D. config.json
- E. workflow.yml
Answer: A
Explanation:
The action.yml file defines the inputs and outputs for a GitHub Action. This file contains metadata about the action, including the required inputs and outputs, as well as other configurations like the action's description, runs, and environment setup.
NEW QUESTION # 60
When creating and managing custom actions in an enterprise setting, which of the following is considered a best practice?
- A. creating a separate branch in application repositories that only contains the actions
- B. creating a separate repository for each action so that the version can be managed independently
- C. creating a single repository for all custom actions so that the versions for each action are all the same
- D. including custom actions that other teams need to reference in the same repository as application code
Answer: B
Explanation:
Creating a separate repository for each custom action allows you to manage the versioning independently for each action. This approach provides flexibility, as each action can be updated, tested, and versioned separately, avoiding potential conflicts or dependencies between different actions.
NEW QUESTION # 61
