1. Which statement best describes how the four major AI coding tools (Cursor, Copilot, Claude Code, and Windsurf) position themselves in the market?

   1. The tools compete mainly on logo design and brand recognition
   2. Each tool occupies a different position along the spectrum from simple autocomplete to full autonomous agent capabilities
   3. They all provide identical functionality with different pricing
   4. All four tools focus primarily on terminal-based command execution

2. When selecting an AI coding assistant for your team, what is the recommended approach according to best practices?

   1. Choose by understanding your team's specific workflow needs rather than hype
   2. Select the tool that was most recently released
   3. Choose based on public benchmark scores and marketing claims
   4. Pick the tool with the lowest per-seat cost regardless of features

3. What does the lesson recommend regarding vendor pricing for AI coding tools?

   1. You should verify pricing on the day you sign a contract, not when you started evaluating
   2. All vendors offer identical pricing structures
   3. Pricing only affects enterprise customers, not individual developers
   4. Pricing remains stable for at least two years once set

4. A team wants to evaluate two AI coding assistants systematically. What methodology does the lesson recommend?

   1. Run automated benchmarks on a public dataset for one hour
   2. Compare the tools based on their GitHub star counts
   3. Have one engineer use each tool exclusively for two weeks, then compare PR throughput, escape defects, and self-reported friction
   4. Read user reviews on third-party websites for one week

5. Which of the following is NOT something AI can reliably predict about AI coding assistants?

   1. The exact syntax errors in your current codebase
   2. Which tool will dominate the market in 12 months
   3. Which model architecture a tool uses internally
   4. How much latency you'll experience when generating code

6. What are the three main repo-context strategies that AI coding assistants use to understand your codebase?

   1. Code formatting, linting, and type checking
   2. Git commits, pull requests, and merge conflicts
   3. Symbol index, embeddings, and full-load approaches
   4. Web scraping, API calls, and database queries

7. What do audit logs provide for teams using AI coding assistants?

   1. Faster autocomplete suggestions based on history
   2. Automatic code refactoring suggestions
   3. A record of which AI models were used and when, useful for security and compliance review
   4. Real-time collaboration features

8. What is 'model pinning' in the context of AI coding assistant administration?

   1. The practice of locking your code files with a password
   2. A feature that prevents code from being uploaded to the cloud
   3. Ensuring all developers on a team use the exact same AI model version for consistency
   4. Automatically selecting the fastest model for every task

9. Why is comparing AI coding tools using only public benchmarks insufficient?

   1. Benchmarks measure only price, not capability
   2. Public benchmarks require a paid subscription to access
   3. Benchmarks are always wrong and should be ignored
   4. Public benchmarks test generic code, not your specific codebase's patterns and architecture

10. What are 'escape defects' in the context of evaluating AI coding assistants?

    1. Memory leaks in the AI assistant itself
    2. Defects that slip through code review and make it into production
    3. Syntax errors that prevent code from compiling
    4. Documentation errors in user manuals

11. What does 'self-reported friction' measure during an AI coding assistant evaluation?

    1. Number of help desk tickets filed
    2. The physical latency between typing and autocomplete appearing
    3. The amount of time spent configuring the tool
    4. How difficult developers find the tool to use, based on their own feedback

12. What does SSO stand for in the context of AI coding assistant admin controls?

    1. Secure Socket Output, an encryption protocol
    2. Single Sign-On, allowing users to access the tool with one set of credentials
    3. Source System Operator, a role in the development team
    4. Super Smart Optimization, a feature that improves code quality

13. Why might two different AI coding assistants have dramatically different performance on the same codebase?

    1. The tools have different colored user interfaces
    2. One tool runs on faster hardware
    3. Each tool uses different context strategies and training data, leading to varying effectiveness on different code patterns
    4. One tool is simply better than the other in all cases

14. What is 'full-load' in the context of how AI coding assistants understand your repository?

    1. Compressing code files to save storage space
    2. Loading the entire codebase into context so the AI can see all code at once
    3. Copying all files to a new repository
    4. A backup strategy for code repositories

15. Which metric would best indicate an AI coding assistant is improving a team's productivity?

    1. Higher memory usage on developer machines
    2. Longer coding sessions without breaks
    3. More syntax errors being generated
    4. Increased PR throughput (more pull requests completed per week)
