| Question type | Answer structure |
|---|---|
| Define protocol | One precise definition → central mechanism → one correct example |
| Compare two protocols | Two-column table with distinct comparable points → application |
| Explain ARP or DHCP | Purpose → actors → ordered messages → result |
| Explain routing algorithm | Initialization → update/selection rule → repeat/stop → path extraction |
| Draw a header | Label fields and widths → explain field meanings → length convention |
For a 2-mark answer, keep the explanation focused on the requested points. For a 3-mark algorithm/numerical, show the essential sequence, not just a memorized final number. Original 10-mark PYQs here intentionally contain longer working.
