NEW QUESTION # 45
You are a developer working on developing reusable workflows for your organization. What keyword should be included as part of the reusable workflow event triggers?
Answer: B
Explanation:
To make a GitHub Actions workflow reusable, you must include the workflow_call keyword under the on key.
This specific event trigger allows the workflow to be called by other "caller" workflows rather than only triggering on standard events like a code push or pull request.
Reusable Workflow Syntax
A basic reusable workflow structure using the workflow_call trigger typically looks like this:
on:
workflow_call:
inputs:
# Optional: Define inputs to be passed from the caller
username:
required: true
type: string
secrets:
# Optional: Define secrets to be passed from the caller
env_token:
required: true
Key Components of workflow_call
inputs: Used to define non-sensitive data (strings, numbers, or booleans) that the caller workflow must or can provide.
secrets: Used to define sensitive data that the caller must pass to the reusable workflow.
outputs: Used to map data from jobs within the reusable workflow so they can be used by the caller workflow.

NEW QUESTION # 46
You are a DevOps engineer working on a custom action. You want to conditionally run a script at the start of the action, before the main entry point. Which code block should be used to define the metadata file for your custom action?
Answer: D
Explanation:
JavaScript action metadata supports the runs.pre property for specifying a script that executes before the action ' s main entry point. The optional runs.pre-if property controls whether that pre-script executes.
Therefore, option B uses the correct metadata structure: pre identifies start.js, pre-if supplies the condition, and main identifies the principal action code. GitHub does not define start, start-if, before, or before-if metadata properties. Current GitHub documentation lists newer supported Node.js runtimes, such as Node.js
20 and Node.js 24, rather than the historical node16 shown in this exam item; however, the tested metadata structure remains pre, pre-if, and main. Thus, among the supplied options, B is structurally correct.
NEW QUESTION # 47
As a DevOps engineer, you are developing a composite action. You have a step that needs to be executed against a subdirectory. Which code snippet should you use within the composite action to specify the directory?
Answer: A
Explanation:
For a run step in a composite action, GitHub Actions supports the working-directory property to specify the directory in which the command executes. The property belongs to the individual step, alongside properties such as run and shell. The generic keyword directory is not part of GitHub Actions metadata syntax.
Composite actions declare runs.using: composite, after which runs.steps defines the reusable sequence of commands or actions. An input such as inputs.dir can therefore be referenced through an expression and assigned to working-directory. GitHub ' s action metadata reference explicitly defines runs.steps[*].working- directory as the supported property for controlling the execution directory of a composite-action command.
Therefore, option B is the valid implementation.
NEW QUESTION # 48
You are a DevOps engineer working on deployment workflows. You need to execute the deploy job only if the current branch name is feature-branch. Which code snippet will help you to implement the conditional execution of the job?
Answer: A
Explanation:
The correct GitHub Actions context property for the short branch or tag name that triggered the workflow is github.ref_name. A job-level if: condition can use this context to control whether the job runs. Therefore, if:
github.ref_name == ' feature-branch ' correctly limits the deploy job to the feature-branch branch. The other options use invalid context paths such as github.ref.name, github.branch_name, and github.branch.name; these are not recognized GitHub Actions properties. In exam terms, this question validates knowledge of workflow expressions, GitHub context variables, and conditional job execution. The important distinction is that github.ref contains the full ref path, while github.ref_name provides the branch or tag name directly.
NEW QUESTION # 49
You are a DevOps engineer working on custom Actions development. You need to handle errors or exceptions as part of the JavaScript-based action code. What should be added to the following code block to handle errors?
const core = require( ' @actions/core ' );
try {
// action code
} catch (error) {
// insert snippet here
}
Answer: B
Explanation:
For a JavaScript action using the official @actions/core toolkit, core.setFailed(error.message) is the documented method for reporting an exception and marking the action as failed. setFailed() logs the supplied message and sets a failing exit code so GitHub records the action and associated check run as unsuccessful.
Neither core.setException() nor core.action.setException() exists in the supported @actions/core API, and action.setError() is likewise not the documented error-handling method. The source PDF visibly contains the first three choices but crops the final distractor; the missing fourth choice was reconstructed from the matching public GH-200 question listing, while the correct answer itself was independently verified against GitHub ' s official documentation. GitHub ' s JavaScript-action example uses this exact catch pattern.
