Network+ practice exams
3 full-length forms, 90 questions each, apportioned to the published domain weightings.
An optimizer inserts a window scale option into a mid-session data segment, hoping to raise throughput on an established connection. How does the receiver treat it?
The answer
It ignores the option on a segment with no SYN bit
Checked against
datatracker.ietf.org, checked August 2026A Window Scale option in a segment without a SYN bit MUST be ignored.

What the exam actually asks you to do
Multiple choice, multiple response, and performance-based questions. The performance-based items drop you into a simulated console, network diagram, or configuration screen and score what you actually do.

The part of Network+ you cannot memorize
Performance-based questions are where memorized dumps fail, because you cannot memorize your way through configuring or analyzing something. A dump can tell you which letter was marked correct. It cannot read the output on the screen in front of you and tell you what it means.
We built 12 of them for Network+, across 4 interaction types. They score with partial credit, and every one ends with a walkthrough of the reasoning rather than just an answer key.
- Sorting
- Drop controls, data states, or hardening tasks into the category each one belongs to.
- Log and output analysis
- Read a real log excerpt, firewall rule set, or command output, then answer what it tells you.
- Matching
- Assign the right technology to each requirement, with a pool bigger than the number of slots so guessing does not pay.
- Sequencing
- Put incident response phases, forensic collection, or a remediation cycle in the order the work actually happens.
Fix a broken network, at a real command line
The Network+ exam puts you at a device and scores what you configured. A lab does the same thing: you get a network with something wrong in it, a console on every device, and a list of conditions your configuration has to satisfy. Check your work as often as you like, and it tells you how far off each one is rather than just marking it wrong.
It runs in your browser. Nothing is installed and no answer is stored, so any configuration that satisfies the conditions passes, not just the one we had in mind.
- The new branch can see itself and nothing else
A branch router was installed with its interfaces addressed and no routes. Users can print locally and reach nothing at head office.

- The warehouse dropped off the network after the maintenance window
A change last night touched the warehouse link. This morning the ERP server cannot reach the warehouse, and the ticket says nothing was changed.
about 20 minutes
- The cameras can reach the payroll server
The IP camera network was put on the same router as the office with no filtering. The cameras must reach their recorder and nothing else on the office side.

Frequently asked questions
How hard is the Network+ N10-009 exam?
Network+ is a step up from A+, you'll need real comfort with subnetting, the OSI model, routing concepts, and troubleshooting methodology. The passing score is 720/900, the highest of CompTIA's core trio.
Should I take Network+ before Security+?
It's the classic path: A+ → Network+ → Security+. Security+ assumes networking fluency, so doing Network+ first makes Security+ substantially easier, but it isn't a formal prerequisite.
Does Network+ cover subnetting?
Yes, IPv4 addressing and subnetting are core to the Networking Concepts domain, and troubleshooting questions frequently hinge on recognizing a wrong mask or gateway.
