Network+ performance-based questions (PBQ) practice

5 questions · Untimed · Notes after each question

Five performance-based questions: map the OSI model, match ports, work out subnets, choose DNS records, read a routing table and pick troubleshooting tools, with a note on every row. Each question gives you a task and a dropdown for every row; check your answers to see a note on each row.

Before you start

Multiple-choice questions have four options and one answer, or five options and two answers when the question says "Choose two." Performance-based questions give you a task with a dropdown for every row. After each answer you see why the key is right and why every other option is wrong.
Check each answer to see the notes before moving on. Checked answers cannot be changed.

We write our own practice questions to help you prepare for CompTIA Network+ (N10-009). They are original, written to the published Network+ N10-009 exam objectives, document version 6.0, and none is a real exam question. Independent practice, not affiliated with or endorsed by CompTIA.
