Sample Practice Questions:

Question 1:

GitHub Copilot generates a code function that compiles without errors but returns incorrect results under specific input conditions. What does this behavior most accurately illustrate as a limitation of generative AI tools?

A. Lack of syntactic understanding

B. Inability to generate runnable code

C. Potential for plausible but incorrect outputs

D. Over-reliance on training data diversity

Answer: C

Explanations:

• A. Explanation for option A: This is incorrect because the code compiles without errors, demonstrating that Copilot understands syntax correctly.

• B. Explanation for option B: This is incorrect because the code does run; it returns incorrect results only under specific conditions.

• C. Explanation for option C: This is correct because generative AI can produce outputs that appear correct (syntactically valid) but contain logical errors or hallucinations under certain conditions.

• D. Explanation for option D: This is incorrect because while training data diversity can affect outputs, the described behavior is a direct example of a model producing a plausible but wrong answer.

Domain : AI Fundamentals and Limitations

Question 2:
A development team notices that GitHub Copilot consistently suggests variable naming conventions and code structures that favor patterns dominant in English-language open-source repositories, underrepresenting styles common in other programming communities. What risk category does this behavior represent within the limitations of generative AI tools?

A. Security vulnerability risk
B. Intellectual property risk
C. Bias and fairness risk
D. Operational stability risk

Answer: C

• Explanation:
  A. Explanation for option A: This is incorrect because the scenario describes stylistic and cultural bias, not a direct introduction of security flaws.
  B. Explanation for option B: This is incorrect because the issue is about representation of coding styles, not about copying licensed code.
  C. Explanation for option C: This is correct because the behavior reflects a bias in the training data that favors certain cultural or linguistic norms, leading to outputs that may not be fair or inclusive of diverse development practices.
  D. Explanation for option D: This is incorrect because the described pattern does not directly impact the runtime stability or performance of the application.

Domain: Responsible AI

Question: 3
Question Text: You are a developer working in a large monorepo with multiple open files from different service domains. You notice that GitHub Copilot's suggestions for a payment processing module seem influenced by context from an unrelated authentication service file you have open in a separate editor tab. Which aspect of Copilot's prompt construction best explains this behavior?

A. Token limit exhaustion causing context leakage
B. Inclusion of all open tabs in the IDE as supplementary context
C. Random sampling of training data for each suggestion
D. The model's inability to distinguish between different programming languages

Answer: B

• Explanation:
  A. Explanation for option A: This is incorrect because token limit exhaustion typically causes loss of context, not the inclusion of context from unrelated files.
  B. Explanation for option B: This is correct because GitHub Copilot automatically includes the content of other files open in the editor, along with the current file, as supplementary context to build the prompt sent to the model.
  C. Explanation for option C: This is incorrect because Copilot suggestions are based on the provided context (current and open files), not random samples from the training data.
  D. Explanation for option D: This is incorrect because the model can distinguish between languages; the issue is that it's drawing from an unrelated file that is open, not misinterpreting the language.
