CompTIA Network+ (N10-009): the practice module
Exam body: CompTIA. Verified for CompTIA Network+ Certification Exam Objectives, N10-009 V9 (Document Version 6.0) on October 18, 2026.
What it covers
Covers: single-answer and multiple-answer multiple-choice questions written to this exam’s outline, format and timing.
Does not cover: performance-based, drag-and-drop. DoMcq is multiple-choice only; the real exam’s other item types are out of scope.
Question format
- Every question has exactly 4 options.
- One or more correct answers per question (multiple-answer stems say how many to choose, and are scored all-or-nothing unless the module says otherwise).
- Not allowed as an option: “all of the above”, “none of the above”.
- Stems follow the exam’s conventions, such as “Which of the following is the most likely reason?”, “Which of the following refers to”, “Which of the following social engineering attacks is this an example of?”, “Which of the following is the first step a network administrator should take”.
Exam mode
The real exam is 90 questions in 90 minutes. Exam mode keeps that pace for any number of questions.
