Sample question 1 of 5
At which OSI layer do switches make forwarding decisions using MAC addresses?
Sample question 2 of 5
A branch needs at least 100 hosts per subnet from 10.20.0.0/16 while creating as many subnets as possible. Which prefix length should be used?
Sample question 3 of 5
Which routing protocol is a link-state protocol that floods link-state advertisements and computes shortest paths with Dijkstra's algorithm?
Sample question 4 of 5
IoT sensors, guest Wi-Fi, and corporate laptops currently share one flat network. What is the primary security benefit of separating them into VLANs with firewall rules between segments?
Sample question 5 of 5
A user can reach internal servers but no internet sites, by name or IP. Other users on the same subnet are fine. ipconfig shows a correct IP and subnet mask but a blank default gateway. What's the fix?
Full Network+ question bank coming
We’re writing the complete bank from the official objectives right now. Leave your email and we’ll tell you when it ships, nothing else, ever.
An honest study plan
1. Read the official objectives first
Download the official objectives from CompTIA and skim every line. The exam can only test what’s listed there, it’s the contract.
2. Weight your study toward Network Troubleshooting and Networking Concepts
Together the top two domains are 47% of the exam. Practice them until your accuracy is consistently above 80%.
3. Drill weak domains, then take a mock exam
Use Domain Drill on your weakest areas, then a full timed mock at real length (Maximum of 90 questions, 90 minutes). Book the real exam when you’re consistently passing mocks, not before.

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.
