Network Foundations & Traffic Flow

Covers Lesson 1 and Lesson 2

Checks whether you can trace a message across a network and name what handles it at each step — not whether you can recite device definitions.

Topics covered

• Device roles and what each one examines
• Hubs, collision domains, and why switches replaced them
• PDU names and the layer each belongs to
• Which addresses a router rewrites and which it preserves

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 1 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.
