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.

Item formats

  • Multiple response
  • Performance-based

The highlighted formats are the ones you cannot answer from memory alone. CompTIA, Network+ exam details

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.

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.
