How Hard Is CompTIA Network+?

What CompTIA publishes about Network+ difficulty, and what it does not

The CompTIA pages checked for this guide give no difficulty rating for CompTIA Network+, and CompTIA's candidate testing policies say it does not publish exam passing rates, because questions and passing rates can change without notice. So a pass rate you see quoted for N10-009 (V9) is not one CompTIA published.

What CompTIA does publish is a description of the person the exam is written for. The Network+ page, checked on October 18, 2026, recommends CompTIA A+ certification plus 9 to 12 months of hands-on experience as a junior network administrator or network support technician. The N10-009 objectives PDF words it differently: a minimum of 9 to 12 months of experience in the IT networking field. Both are recommendations, not booking requirements. The closer you are to that role, the more of the scenarios will describe situations you recognize.

Five Network+ difficulty factors you can check

1. The 720 is a scaled score. You need 720 on a scale of 100 to 900. CompTIA says passing scores are set by statistical analysis and may change, so 720 is not 72% or 80% of the questions. The passing score guide explains what that means for a retake.
2. Performance-based questions change the pacing. The exam has a maximum of 90 questions in 90 minutes, mixing multiple-choice and performance-based items. CompTIA's December 18, 2024 blog says most PBQs appear at the beginning and that you cannot see a clock while working on them. CompTIA's PBQ page adds that simulation PBQs can be skipped and revisited and that partial credit may be given. The pages checked give no PBQ count. The PBQ guide shows how to prepare for them.
3. Troubleshooting is the largest domain. Network Troubleshooting carries 24%, and its first objective, 5.1, is the seven-step troubleshooting methodology. On A+ 220-1201, by contrast, the objectives say the methodology is not a formal objective. On Network+, the order of the steps is testable.
4. Some math has to happen in your head or on a whiteboard. Objective 1.7 asks you to use IPv4 addressing in a scenario, which means subnetting. If you test online, CompTIA's online guidelines allow a digital whiteboard only, with no physical notes. Practice the subnetting method with nothing but scratch space.
5. The wording is vendor-neutral. Objective 5.5 lists device commands in generic forms, such as show mac-address-table and show route. Real vendors spell some of them differently. If you learned on one vendor's equipment, expect to translate.

One more fact raises the ceiling. The objectives say their bulleted examples are not exhaustive, so other technologies tied to an objective may appear.

Where each N10-009 domain tends to feel hard

Your background changes which row hurts most:

A ten-item Network+ self-check

Answer from memory, then read the notes. This is not a score, and it does not predict a result. It shows where your gaps are.

1. How many usable host addresses does a /27 subnet have?
2. SNMP traps never reach the management station. Which UDP port must be allowed toward it?
3. Write 2001:0db8:0000:0000:0000:0000:0000:0010 in its shortest form.
4. A router has a static route to 10.0.0.0/8 and an OSPF route to 10.5.0.0/16. Which one carries a packet to 10.5.9.9?
5. Two switches must carry VLANs 10, 20, and 30 over one link. What kind of port is that, and which tagging standard does it use?
6. Which syslog message is more urgent, severity 2 or severity 5?
7. Which DNS record type answers a reverse lookup, from an address to a name?
8. What does a MAC flooding attack try to fill, and what does the switch do once it is full?
9. A port showed 1,000 CRC errors yesterday and still shows 1,000 today. Is the link failing now?
10. In the seven-step methodology, when do you document findings, actions, outcomes, and lessons learned?

Notes.

1. 30, because 2^5 − 2 = 30. See subnetting.
2. UDP 162, which IANA registers as snmptrap. See ports and protocols.
3. 2001:db8::10. Drop the leading zeros and compress the run of five zero groups once. See IPv6.
4. The OSPF /16. The longest matching prefix wins before administrative distance is compared. See routing.
5. A trunk port using 802.1Q tagging. See switching.
6. Severity 2 (Critical). In RFC 5424, a lower number is more severe than 5 (Notice). See monitoring.
7. PTR, in a reverse zone. See ports and protocols.
8. The switch's MAC address table. If legitimate destinations cannot be learned, unknown unicast traffic may be flooded within the VLAN; known unicast traffic is not automatically all flooded. See network attacks.
9. Not on that evidence. Counters are running totals, and objective 5.2 is about increasing counters. Read it twice, minutes apart. See cable and interface issues.
10. Throughout the process. Documentation is listed as the last step, but the objective says it happens throughout. See the troubleshooting methodology.

Misses in items 1 to 4 point to Networking Concepts and addressing math. Item 5 points to Network Implementation, items 6 and 7 to Network Operations, item 8 to Network Security, and items 9 and 10 to Network Troubleshooting. To turn those misses into a schedule, use how long to study for Network+.

A baseline across all five domains

The self-check is short and leans on recall. For scenario items in every domain, you can set a baseline with the 20 mixed Network+ questions →. Each item is single-answer with an explanation for every option, and the result breaks your misses down by domain. The set includes no performance-based questions, and its percentage is not a scaled score.

The order to study in once you know your gaps is laid out in the Network+ study guide.
