Question 1

You are maintaining a legacy JavaScript codebase that has become difficult to manage due to repeated blocks of similar code across multiple functions. You want to refactor this code to improve readability and maintainability. How can GitHub Copilot help you refactor this code and improve your productivity?

Options :

A : "Ask GitHub Copilot to add more comments to the existing code."

B : "Ask GitHub Copilot to write an entirely new codebase from scratch."

C : "Ask GitHub Copilot to replace repeated code blocks with reusable functions."

D : "Ask GitHub Copilot to automatically update all code to the latest JavaScript version."

Answer: C

Question 2

You are working on a Python function find_max(numbers) that returns the largest number in a list. The function is defined as follows:You want to use GitHub Copilot to help identify edge cases and suggest tests to ensure the function works correctly in all situations. Which approach should you take to get the most comprehensive test suggestions from Copilot?

Options :

A : Ask Copilot to generate tests using large sets of random numbers to ensure scalability.

B : Instruct Copilot to generate test cases for lists that contain only positive numbers, assuming negative numbers are not relevant.

C : Rely on Copilot to generate a basic test for a list of three numbers and manually test other cases.

D : Use Copilot to suggest test cases by outlining possible edge cases, such as an empty list, a list with one element, or a list of all identical elements.

Answer: D

Question 3

You are a team lead in a software development company that has recently adopted GitHub Copilot. You’ve heard about GitHub Copilot Chat, which adds an interactive chat feature to Copilot, and you want to present its main features to your team. Which of the following are key features of GitHub Copilot Chat?

Options :

A : Provides step-by-step explanations for suggested code snippets

B : Collaborates in real-time with other developers on the same project

C : Automatically refactors entire codebases upon request

D : Generates detailed test cases based on user prompts

Answer: A

Question 4

You are tasked with implementing GitHub Copilot in your organization for developers to generate code. Your team is concerned about the ethical implications of using AI in code generation, particularly around bias and unintended consequences in the output. What steps should you take to ensure that GitHub Copilot is used responsibly?

Options :

A : Allow Copilot to generate any code automatically, assuming that the AI system has already been trained to be free of bias.

B : Regularly review the AI-generated code for potential biases and ensure that sensitive data (such as gender, race, or age) is not being unnecessarily handled by the AI suggestions.

C : Rely on user feedback alone to correct any issues with the AI suggestions and handle bias as it arises through manual reporting.

D : Ensure that Copilot-s suggestions are accepted without modification, as they have been optimized for efficiency and accuracy.

Answer: B

Question 5

You are building a web application and need to generate code to handle user authentication, including login, logout, and password reset functionalities. You write the following prompt: # Implement user authentication with login, logout, and password reset. However, Copilot's output lacks security best practices, such as proper hashing of passwords and multi-factor authentication (MFA). Which of the following changes to your prompt would most likely lead to more secure and comprehensive code from GitHub Copilot?

Options :

A : Remove details about login, logout, and password reset to focus only on password hashing, as "Implement user authentication with password hashing."

B : Keep the prompt vague and allow Copilot to handle the implementation logic based on the default practices in the training data.

C : Use multiple prompts, each for a different functionality, such as "Implement login," "Implement password reset," and "Implement logout."

D : Add specific security requirements to the prompt, such as "Implement user authentication with login, logout, password reset, using hashed passwords and multi-factor authentication."

Answer: D
