- The C)NP exam is 100 multiple-choice questions in roughly 2 hours, with a 70% minimum passing score.
- Difficulty comes from breadth across ten modules, not from deep specialization in any single one.
- Mile2 recommends C)HT/C)OST-level or equivalent hardware and operating-system knowledge before you sit the exam.
- An Exam Combo includes two attempts, so a first-try miss does not force an immediate repurchase.
The Honest Difficulty Verdict
Certified Network Principles from Mile2 sits at the foundational end of the networking certification ladder, and that framing should set your expectations. It is not an expert-level exam designed to filter out all but a few candidates. It is a broad check that you understand how networks are built, addressed, secured, run, and planned. The difficulty is real, but it is the difficulty of coverage: ten distinct areas, each needing working familiarity, in a single 100-question sitting.
If you have ever administered a small office network, worked a help desk, or built and repaired PCs, much of the material will feel like putting names to things you already do. If your technical background is thin, the exam is still achievable, but you will be learning vocabulary, protocols, and concepts from scratch, which takes noticeably longer. For a data-oriented look at outcomes, see our breakdown of the C)NP pass rate and what the available data shows.
What the Exam Actually Looks Like
The mechanics are straightforward, and knowing them removes a layer of avoidable anxiety.
| Exam Element | C)NP Detail |
|---|---|
| Question count | 100 multiple-choice questions |
| Time allowed | Approximately 2 hours |
| Minimum passing score | 70% |
| Delivery | Through your Mile2 account / Learning Management System |
| Recommended background | C)HT/C)OST-level or equivalent hardware and OS knowledge |
| Training requirement | None; course purchase is not required |
Two minutes per question is a comfortable pace for a multiple-choice exam, which means time pressure is rarely the main issue. The pass line of 70% means you can miss up to 30 questions and still succeed. That margin is forgiving enough that a weak domain or two will not sink you, provided your overall coverage is solid. We cover the scoring threshold in more detail in our guide to the C)NP passing score.
Mile2's general FAQ describes its standard exams as online and on demand, so scheduling is typically flexible rather than tied to a fixed testing window. Always follow the exam-specific instructions that come with your purchase, and see C)NP exam dates and scheduling for how to plan your sitting.
Question style
Expect conventional multiple-choice items that test recognition and applied understanding: identifying the right protocol for a scenario, choosing the correct device for a connection need, recognizing a security principle, or sequencing a basic network planning decision. The ten course modules are the preparation scope, so the questions draw from the topics those modules cover rather than from an unpublished weighting scheme. Because the domain list reproduces official course modules without published weights, you should not assume any one domain is guaranteed to dominate. Prepare evenly.
Where Candidates Struggle Most
Mile2 does not publish per-domain pass data, so any claim that one domain is statistically "the hardest" would be speculation. What we can do is identify the areas where the nature of the material tends to trip people up, based on how the topics are structured. For a full breakdown of each area, read our complete guide to all 10 C)NP content areas.
Domain 3: TCP/IP Primer
This is the conceptual backbone of the exam and the area where beginners feel the steepest climb.
- Addressing and how hosts identify one another on a network
- How data moves between layers and between devices
- Common protocols and what job each one performs
- Why this module underpins nearly every later domain
Domain 4: Connecting Networks with Switches and Routers
Candidates who have only used networks, never configured or reasoned about them, find the distinction between devices surprisingly slippery.
- What switches do versus what routers do, and why the difference matters
- How traffic is forwarded within a network versus between networks
- Recognizing which device fits a given scenario
Domains 6 and 7: Security Principles and Defending the Network
These two modules form a pair, and candidates often underestimate how much of the exam they represent together.
- Foundational security concepts and the reasoning behind them
- Defensive measures used to protect network resources
- Distinguishing between principles (the "why") and defenses (the "how")
Domain 5: Wireless Networking
Wireless is a compact topic but full of terminology. Candidates who treat it as "just Wi-Fi" are often surprised by the vocabulary and the security considerations tied to it.
- How wireless networks differ from wired ones in operation and risk
- Terminology you must recognize on sight
Domains 8 through 10: Technology, Daily Operations, and Planning
Network Technology Boom, Day to Day Networking, and Network Planning feel softer than the protocol-heavy modules, which makes them easy to under-prepare. They reward candidates who understand how networks are actually run and designed in practice, not just how packets move.
- Emerging technologies and how they affect networks
- Routine administration and operational concerns
- Planning considerations before a network is built or expanded
How Your Background Changes the Difficulty
The same exam feels very different depending on where you start. Mile2's own recommendation is C)HT/C)OST-level or equivalent hardware and operating-system knowledge. That recommendation tells you something: the exam assumes you already understand the machines that sit on the network. If you do not know what a network interface does or how an operating system handles connections, the networking material has less to attach to.
| Your Starting Point | Likely Experience |
|---|---|
| Help desk or desktop support background | Hardware and OS fluency carries over; focus effort on TCP/IP, switching and routing, and the security domains. |
| Small-office or home-lab experience | Practical familiarity helps with Domains 2 and 9; formal terminology in wireless and planning may need attention. |
| Career changer with little IT exposure | Plan to build hardware and OS basics first, then work through the ten modules in order. |
| Already holds an entry-level IT credential | Likely the smoothest path; targeted review of gaps may be enough. |
Key Takeaway
Audit yourself against the ten domain names before you commit to a timeline. If you can explain each module title in your own words, you are close. If three or more feel unfamiliar, budget for structured learning rather than just practice questions. Our C)NP requirements guide explains exactly what is and is not required to sit the exam.
The Network+ Comparison
Many candidates ask whether C)NP is easier or harder than CompTIA Network+. A fair answer requires care. The two share subject matter, so preparing for one builds knowledge relevant to the other. But that overlap is a statement about topics, not credentials: studying for Network+ does not confer a CompTIA certification, and it does not establish that C)NP is equivalent to Network+'s current objectives. They are separate credentials from separate bodies, with their own blueprints.
The practical takeaway is that someone with solid networking fundamentals from any source will find the C)NP's ten modules familiar. The exam format also differs from what you may have seen elsewhere: it is delivered through your Mile2 account rather than a third-party testing center workflow, with 100 multiple-choice questions and a 70% pass line. Do not assume that techniques or timing from another vendor's exam transfer one-to-one.
Attempts, Access, and Retake Realities
Difficulty is partly about stakes, and the stakes here are moderated by how the product is structured. The Exam Combo includes the certification exam, a preparation guide, a practice quiz or simulator, and two exam attempts. That means a first miss is a setback, not a restart from zero.
It also helps to separate three things that are easy to confuse: the exam itself, the optional five-day training with its 40 course CEUs, and your access periods for course and voucher materials. The training and its CEUs are separate from the exam. You can sit the exam without buying the course, but if you do take the training, its access period is distinct from the three-year validity of the credential you earn.
To rehearse before your real attempt, use the C)NP practice test and work through scenario-style questions that mirror the multiple-choice format. Pair it with the included practice quiz or simulator from your Exam Combo.
A Domain-Ordered Preparation Plan
Because the ten modules build on one another, the order you study them matters more than the generic habits you use. Foundations first, then the protocol and device layers, then the security pair, then the applied modules. This is one possible sequence for a candidate with moderate background; stretch or compress it to fit your situation. For a fuller roadmap, see our C)NP study guide.
Domains 1 and 2: Foundations and Physical Networking
- Lock in core terminology and network types before anything else depends on it
- Review cabling, hardware, and physical connectivity concepts
Domain 3: TCP/IP Primer
- Give this module the most time; later domains lean on it
- Practice explaining addressing and protocol roles aloud
Domains 4 and 5: Switches, Routers, and Wireless
- Drill the switch-versus-router distinction until it is automatic
- Build a wireless vocabulary list and review security implications
Domains 6 and 7: Security Principles and Defending the Network
- Separate security principles from the defensive measures that implement them
- Connect each defense back to the threat it addresses
Domains 8, 9, and 10: Technology Boom, Daily Operations, Planning
- Review the applied modules that are easy to skim past
- Finish with full practice runs and review every miss by domain

What Passing Gets You and How Long It Lasts
Passing earns a credential valid for three years, a period separate from any course or voucher access you hold. Renewal currently offers two paths: documenting 60 qualifying CEUs within the three-year cycle and paying the applicable renewal fee (the U.S. CE-renewal fee is $200), or taking an accepted current-examination route. Policy and ethics acknowledgment applies either way. Check Mile2's current renewal-path policy rather than assuming an exam and CEUs are both always required.
Whether the effort is worth it depends on your goals. C)NP is a foundational credential, so it tends to support entry-level and support-oriented roles rather than senior positions on its own. Explore what the market looks like in our guides to C)NP jobs and the ROI of the C)NP certification, and see the C)NP salary guide for earnings context. If you are still orienting yourself to the credential, start with what C)NP certification is.
Frequently Asked Questions
It is manageable but broad. Beginners without hardware and operating-system knowledge face the steepest climb because Mile2 recommends C)HT/C)OST-level or equivalent background. With structured study across all ten modules, it is a realistic goal.
The exam has 100 multiple-choice questions over approximately 2 hours, and the minimum passing score is 70%. That allows up to 30 incorrect answers while still passing.
No. Course purchase is not required. The five-day training and its 40 course CEUs are separate from the exam, so you can prepare through self-study and take the exam on its own.
The Exam Combo includes two exam attempts, so you can retake without repurchasing. Once both attempts are exhausted, further paid access is needed, so use your first attempt seriously and review misses by domain.
The subject matter overlaps, so Network+ preparation builds relevant knowledge. However, that overlap does not confer CompTIA certification or make C)NP equivalent to Network+'s current objectives. They remain separate credentials with separate requirements.
The C)NP exam rewards steady, even preparation across all ten modules rather than cramming one specialty. Build your foundation, give TCP/IP and the security pair extra time, and test yourself with realistic questions on our practice test site before you sit the real thing.
