GitHub-Copilot Exam Practice Test Instant Access

Question 1

How does GitHub Copilot suggest code optimizations for improved performance?

ABy analyzing the codebase and suggesting more efficient algorithms or data structures.

BBy automatically rewriting the codebase to use more efficient code.

CBy enforcing strict coding standards that ensure optimal performance.

DBy providing detailed reports on the performance of the codebase.

Answer : A

GitHub Copilot suggests code optimizations by analyzing the codebase and recommending more efficient algorithms or data structures.

Question 2

How does GitHub Copilot Chat ensure that a function works correctly?

ABy suggesting assertions based on the code's context and semantics.

BBy automatically writing all the tests for the function.

CBy writing the implementation code for the function.

DBy executing the test cases to validate the correctness of the code.

Answer : A

GitHub Copilot Chat can suggest assertions based on the code's context and semantics to help developers verify the correctness of their functions. These assertions serve as checks that the function behaves as expected under various conditions.

Question 3

What is a key consideration when relying on GitHub Copilot Chat's explanations of code functionality and proposed improvements?

AThe explanations are dynamically updated based on user feedback.

BReviewing and validating the generated output for accuracy and completeness.

CGitHub Copilot Chat uses a static database for generating explanations.

DThe explanations are primarily derived from user-provided documentation.

Answer : B

While GitHub Copilot Chat can provide helpful explanations and suggestions, it's crucial to review and validate the generated output. Copilot's suggestions are based on its training data, and they may not always be perfectly accurate or complete. Human judgment is essential to ensure the quality and correctness of the code.

Question 4

Which of the following scenarios best describes the intended use of GitHub Copilot Chat as a tool?

AA complete replacement for developers generating code.

BA productivity tool that provides suggestions, but relying on human judgment.

CA solution for software development, requiring no additional input or oversight.

DA tool solely designed for debugging and error correction.

Answer : B

GitHub Copilot Chat is designed to be a productivity enhancer, not a replacement for human developers. It provides suggestions and assists with coding tasks, but the final decision and validation always rest with the developer. Copilot Chat is meant to augment the developer's workflow, making it faster and more efficient, but it does not remove the need for human oversight and judgment.

Question 5

What is a benefit of using custom models in GitHub Copilot?

AResponses are faster to produce and appear sooner

BResponses use practices and patterns in your repositories

CResponses use the organization's LLM engine

DResponses are guaranteed to be correct

Answer : B

Custom models in GitHub Copilot allow the tool to learn from the specific code patterns and practices within your repositories. This results in suggestions that are more aligned with your organization's coding standards and conventions, improving the relevance and accuracy of the generated code.

Question 6

What method can a developer use to generate sample data with GitHub Copilot? (Each correct answer presents part of the solution. Choose two.)

AUtilizing GitHub Copilot's ability to create fictitious information from patterns in training data.

BLeveraging GitHub Copilot's ability to independently initiate and manage data storage services.

CUtilize GitHub Copilot's capability to directly access and use databases to create sample data.

DLeveraging GitHub Copilot's suggestions to create data based on API documentation in the repository.

Answer : A, D

GitHub Copilot can generate sample data by creating fictitious information based on patterns in its training data and by using suggestions based on API documentation within the repository.

Question 7

How can GitHub Copilot assist with code refactoring tasks?

AGitHub Copilot can fix syntax errors without user input.

BGitHub Copilot can automatically rewrite code to follow best practices.

CGitHub Copilot can suggest refactoring improvements for better code quality.

DGitHub Copilot can remove unnecessary files from the project directory.

Answer : C

GitHub Copilot can analyze existing code and suggest refactoring improvements to enhance code quality, readability, and maintainability. It can propose changes to improve code structure, reduce complexity, and follow best practices.
