1. Why is observability particularly important for scheduled AI cron jobs running on Vercel?

   1. Vercel's platform automatically notifies users of all job failures
   2. Scheduled jobs often run during off-peak hours when no one is actively monitoring them
   3. AI cron jobs consume more server resources than regular cron jobs
   4. Scheduled AI jobs require human approval before executing each run

2. According to the key concepts, what three things can AI specifically help create for Vercel cron jobs?

   1. Load balancers, CDNs, and SSL certificates
   2. Logging schema, alert rules, and daily health summaries
   3. Database backups, security scans, and performance tests
   4. Code snippets, documentation, and user interfaces

3. A Vercel cron job runs successfully every day and returns an HTTP 200 status code, but the output contains invalid data that no downstream system can use. What does the lesson warn could happen in this scenario?

   1. The job would automatically be paused by Vercel's safety systems
   2. The job could run for months unnoticed because status-based monitoring only checks if the job executed, not whether the output is valid
   3. The job would trigger a credit card charge for excess API usage
   4. The job would fail the next deployment and prevent new releases

4. What limitation of AI does the lesson explicitly identify when building observability for cron jobs?

   1. AI cannot be used for jobs that run less than once per day
   2. AI cannot connect to the Vercel dashboard
   3. AI cannot write code in JavaScript or TypeScript
   4. AI cannot predict the specific cause of the next outage that will occur

5. The lesson mentions that logging alone is insufficient for cron job monitoring. What must complement logging to create effective observability?

   1. Extended API rate limits
   2. Video recording of each cron job execution
   3. Manual code review after every job run
   4. Runtime alerting that checks actual outputs, not just whether the job executed

6. What is a logging schema in the context of cron job observability?

   1. A defined structure that specifies what information should be recorded each time a cron job runs
   2. A list of all Vercel projects in an account
   3. A visual diagram showing job execution times
   4. A template for user authentication

7. Why might a cron job that appears to run successfully still be considered a failure from an observability perspective?

   1. Because it completes without errors but produces output that downstream systems cannot process or use
   2. Because it runs faster than expected
   3. Because it uses more memory than allocated
   4. Because it was triggered manually instead of on schedule

8. The lesson mentions creating a daily cron health summary. What is the primary audience for this summary?

   1. Developers or operations teams who need an overview of all scheduled job statuses
   2. Vercel support staff
   3. Investors reviewing company metrics
   4. End users of the application

9. What distinguishes a well-designed observability layer for cron jobs from simple logging?

   1. It includes both logging of what happened AND alerting when something goes wrong
   2. It automatically fixes failed jobs without human intervention
   3. It requires no configuration to work
   4. It stores logs for only 24 hours before deletion

10. Based on the lesson, if you only monitor whether a Vercel cron job executed (checking status code), what important failure mode might you miss?

    1. The job consumed too much CPU
    2. The job was deleted from the Vercel dashboard
    3. The job triggered a security audit
    4. The job ran but produced output that is empty, corrupted, or otherwise unusable

11. In the context of this lesson, what does the term 'silent failure' refer to?

    1. A database query that returns no results
    2. A failed deployment that gets automatically rolled back
    3. A Vercel function that runs faster than expected
    4. A cron job that executes without errors but produces results that are incorrect or unusable, going unnoticed by the team

12. What does the lesson say AI can draft for each individual cron job?

    1. A marketing plan for the AI product
    2. A complete replacement for the job's code
    3. A new cron schedule that replaces the existing one
    4. A logging schema that defines what information should be captured when that specific job runs

13. Why is it not enough to rely solely on the fact that a cron job executed without errors?

    1. Error-free jobs still require manual code review
    2. Error-free jobs are automatically archived
    3. The job could have executed successfully but produced invalid or empty output that no one will notice
    4. Vercel charges extra for error-free jobs

14. What is the relationship between logging and alerting in effective cron job observability, as described in the lesson?

    1. Alerting should be disabled if logging is enabled
    2. They are interchangeable terms for the same thing
    3. They are complementary; logging records what happened while alerting notifies when there's a problem
    4. Logging should be used instead of alerting for cost savings

15. Based on the lesson, what is one thing AI definitely cannot do when setting up observability for Vercel cron jobs?

    1. Recommend any alert rules
    2. Suggest any logging schema for cron jobs
    3. Predict the specific cause of the next outage that will occur
    4. Format any summary of cron job performance
