Week 9 Checkpoint

Covers Lessons 1 through 4

Spans all four Week 9 lessons — why automation exists, the API and data-format mechanics, the SDN and virtualization architecture, and the AI layer on top.

Topics covered

• Automation and controllers
• The three planes
• REST verbs, status codes, and JSON
• SDN and API directions
• Cloud and virtualization
• Generative versus predictive AI

Every question here is answerable from the first-party notes of the lessons above. You commit to an answer before you see whether it was right.

This quiz is a Week 9 milestone in its own right. Passing it does not change the completion state of any individual lesson, and you do not need it to finish the lessons it covers.
