Module Assessment

1.

What is the primary hidden cost of duplicate code in software development?

Increased storage requirements for the codebase.

Maintenance overhead requiring updates in multiple locations when bugs are found or features change.

Slower compilation times due to repeated code parsing.

2.

Which principle guides developers to avoid repeating logic across their codebase?

Single Responsibility Principle (SRP)

Don't Repeat Yourself (DRY)

Open/Closed Principle (OCP)

3.

What is the most fundamental refactoring technique for consolidating duplicate code?

Create static helper classes for all shared functionality.

Extract Method technique

Implement inheritance hierarchies to share common code.

4.

What is the golden rule for safe code refactoring when consolidating duplicate code?

Complete all refactoring changes at once for efficiency.

Make small, safe steps with testing after each change.

Focus on performance optimization before consolidating duplicate code.

5.

What is the primary purpose of GitHub Copilot's Ask mode when identifying duplicate code?

To automatically refactor duplicate code across the entire codebase.

To analyze code and identify potential duplication without altering the code.

To generate new code that replaces all duplicate logic.

6.

What key difference distinguishes Agent mode from Ask mode in GitHub Copilot?

Agent mode can access more files in the workspace than Ask mode.

Agent mode can modify code across multiple files while Ask mode only provides analysis.

Agent mode works faster than Ask mode for code analysis.

7.

What is a best practice when creating prompts for GitHub Copilot Agent mode to consolidate duplicate code?

Use vague references like 'this file' and 'this function' to let the agent decide.

Be specific and clearly identify the methods, classes, and desired outcome.

Request all refactoring changes to be completed in a single large operation.
