- C)NP means Certified Network Principles, a foundational networking credential from Mile2.
- The exam is 100 multiple-choice questions in roughly 2 hours, with a 70% minimum passing score.
- Ten unweighted course modules define the preparation scope, from network fundamentals to network planning.
- Credential validity is 3 years; the U.S. CE-renewal fee is $200.
What C)NP Stands For
On this site, C)NP stands for Certified Network Principles. The unusual closing parenthesis is part of how Mile2 styles its certification names, so you will see the same pattern across its other credentials. The letters spell out a simple promise: the holder understands the principles that make networks work, rather than just the buttons on one vendor's equipment.
That distinction matters when you search for the term. The same acronym is used elsewhere in the professional world for unrelated credentials, so a general web search can send you to material that has nothing to do with networking or with this exam. If you are here to learn about the Mile2 credential, everything that follows refers only to Certified Network Principles. For related explainers that approach the same question from different angles, see What Does C)NP Stand For? and C)NP Meaning.
Who Issues It and How It Is Delivered
Certified Network Principles is issued by Mile2, a provider of cybersecurity and IT certification training. The exam is taken through the candidate's Mile2 account, which runs on the Learning Management System. Mile2's general FAQ describes its standard exams as online and on demand, though you should always follow the exam-specific instructions that arrive with your purchase, since those take precedence over general descriptions.
Two points about the commercial structure are worth understanding early:
- Course purchase is not required. You can sit the exam without buying the training course, which makes the credential accessible to self-directed learners.
- The Exam Combo bundles several items. It includes the certification exam, a preparation guide, a practice quiz or simulator, and two exam attempts. If you use both attempts without passing, further paid access is needed.
Training and certification are separate products. Mile2 offers a five-day instructor-style course that carries 40 course CEUs, but those hours belong to the course, not the exam. For a closer look at the learning side, read C)NP Training, and for the cost side see C)NP Certification Cost 2026: Complete Pricing Breakdown.
What the Credential Actually Covers
The scope of C)NP follows ten official course modules. It is important to be precise about what these represent. Mile2's published outline lists the modules, but those module lists are unweighted. They describe the material you should prepare, not a separately established, weighted exam blueprint. In practice, that means you should not assume one module carries a fixed percentage of the exam, and you should prepare across all ten rather than gambling on a favorite.
The recommended background is hardware and operating-system knowledge at roughly the level of Mile2's C)HT or C)OST courses, or equivalent experience. If you can already describe what a network interface card does, how an operating system handles a network connection, and what happens when a device powers on and joins a network, you are the intended candidate.

The Ten Preparation Modules in Detail
Below is what each module asks of you. The names come directly from the official outline, and the bullet points describe the kinds of concepts worth mastering within each theme.
Foundations: Modules 1 to 3
Domain 1: Introduction to Network Fundamentals
This is the vocabulary layer. Candidates should be comfortable with what a network is and why networks are built the way they are.
- Common network types and topologies
- Layered models and why layering exists
- Clients, servers, and peer relationships
- How data moves conceptually from one host to another
Domain 2: The Physical Networking Fundamentals
Here the focus is on the tangible: what carries the signal and what connects devices.
- Copper, fiber, and the tradeoffs between media
- Connectors, cabling standards, and distance limits
- Network interface hardware and physical-layer troubleshooting
- How physical problems present as symptoms higher up
Domain 3: TCP/IP Primer
For most candidates this is the heaviest conceptual module, because nearly everything later depends on it.
- IP addressing and subnetting logic
- Common protocols and the ports associated with them
- Name resolution and address assignment
- How packets are encapsulated and delivered
Connectivity and Access: Modules 4 and 5
Domain 4: Connecting Networks with Switches and Routers
This module separates local delivery from inter-network delivery and explains the devices responsible for each.
- How switches forward frames within a segment
- How routers forward packets between networks
- Basic routing concepts and default gateways
- When segmentation helps performance and containment
Domain 5: Wireless Networking
Wireless adds a shared, open medium, which changes both performance and risk.
- Wireless standards and their general characteristics
- Access point roles and basic deployment concerns
- Encryption and authentication options for wireless links
- Common sources of interference and coverage problems
Protection: Modules 6 and 7
Domain 6: Security Principles
Security appears here as a set of principles, not a product catalog.
- Confidentiality, integrity, and availability
- Authentication, authorization, and accounting concepts
- Common threat categories facing networks
- Why defense in depth outperforms any single control
Domain 7: Defending the Network
This module turns principles into controls.
- Firewalls, filtering, and the idea of a network perimeter
- Monitoring and detection concepts
- Hardening devices and reducing attack surface
- Remote access and encrypted tunnels at a conceptual level
Operations and Direction: Modules 8 to 10
Domain 8: Network Technology Boom
This module surveys newer technologies that have reshaped how networks are built and consumed.
- Virtualization and its effect on network design
- Cloud-connected and remote-access models
- Mobile and always-connected device trends
- How new technology changes both capability and exposure
Domain 9: Day to Day Networking
Practical administration is the theme: keeping a working network working.
- Troubleshooting methodology and common diagnostic tools
- Documentation, change awareness, and routine maintenance
- Interpreting symptoms and isolating the failing layer
- Supporting users and recognizing recurring fault patterns
Domain 10: Network Planning
The final module looks forward: designing and sizing a network before it is built.
- Gathering requirements and estimating capacity
- Choosing topology, devices, and addressing schemes
- Planning for growth, redundancy, and security from the start
- Budget and lifecycle considerations
Exam Format, Registration and Scoring
The mechanics are refreshingly simple compared with many industry exams, and knowing them removes a layer of test-day anxiety.
| Item | Detail |
|---|---|
| Issuing body | Mile2 |
| Question count | 100 questions |
| Question type | Multiple choice |
| Duration | Approximately 2 hours |
| Minimum passing score | 70% |
| Delivery | Through your Mile2 account and Learning Management System |
| Course required? | No |
| Exam Combo attempts | Two included |
At 100 questions over about two hours, you have a little over a minute per question on average. That is comfortable for conceptual multiple-choice items, but it rewards candidates who recognize terminology quickly. A 70% minimum means you can miss up to 30 questions and still pass, which creates room for weak spots but not for ignoring an entire module. If you want the full picture on scoring, see C)NP Passing Score 2026: Exactly What You Need to Pass, and for scheduling logistics see C)NP Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
Candidates often ask about difficulty and pass rates. This site does not publish a pass-rate figure it cannot source, and you should be wary of anyone who does. For a qualitative treatment, see How Hard Is the C)NP Exam? Complete Difficulty Guide 2026 and C)NP Pass Rate 2026: What the Data Shows.
Who Should Pursue It
Certified Network Principles suits people at the start of a networking or security path, or those whose current role touches networks without being fully dedicated to them. Typical profiles include:
- Help desk and desktop support staff who want to move from fixing endpoints to understanding the network beneath them.
- Aspiring network administrators building a structured foundation before specializing.
- Career changers who need a recognized credential to anchor their first IT role.
- Security-minded newcomers who understand that defending a network requires knowing how it works first.
Employers who value this kind of foundation are generally those hiring for entry-level infrastructure, support, and junior security roles, where candidates are expected to reason about connectivity and basic defense. Because the credential is foundational, it works best as a stepping stone and as evidence of baseline competence, not as a standalone qualification for senior engineering positions. For a realistic view of roles, read C)NP Jobs, and to weigh the investment, see Is the C)NP Certification Worth It? Complete ROI Analysis 2026. Earnings depend heavily on location, employer, and the rest of your skill set, which is why the C)NP Salary Guide 2026: Complete Earnings Analysis treats compensation qualitatively rather than promising a figure.

Credential Validity and Renewal
A C)NP credential is valid for 3 years. That validity period is separate from any access window attached to a course or an exam voucher, so do not confuse the time you have to use a purchase with the lifespan of the credential itself.
When the 3-year cycle ends, Mile2's current renewal paths offer a choice:
- The CEU route: document 60 qualifying CEUs within the 3-year cycle and pay the applicable renewal fee. The U.S. CE-renewal fee is $200.
- The examination route: take an accepted current examination instead.
Policy and ethics acknowledgment applies under the renewal program. A common misreading is to assume you must complete both an exam and a set of CEUs every cycle. That is not how the current paths are framed: they are alternatives, and you should check the live renewal-path policy before planning, since policies can be updated. Do not treat the exam and CEUs as universally cumulative requirements.
Key Takeaway
Keep a running log of qualifying CEU activity from day one of your credential. Documenting as you go makes the 60-CEU renewal route far easier than reconstructing three years of activity at the deadline.
Sequencing Your Preparation by Module
Because the ten modules build on one another, the order you study them matters more than the total hours. Here is one way to schedule the material, with the reasoning attached to each stage. If you want a broader plan, C)NP Study Guide 2026: How to Pass on Your First Attempt covers the full approach.
Domains 1 and 2: vocabulary and the physical layer
- Learn the layered-model language first, since every later topic uses it.
- Pair cabling and media facts with the idea that physical faults show up as higher-level symptoms.
Domain 3: TCP/IP Primer
- Give this the most time; addressing, subnetting logic, and protocols underpin switching, routing, security, and troubleshooting.
- Practice reasoning through addressing scenarios rather than memorizing lists.
Domains 4 and 5: switches, routers, and wireless
- Contrast frame forwarding within a segment against packet forwarding between networks.
- Treat wireless as the same concepts applied to a shared, open medium.
Domains 6 and 7: security principles, then defense
- Study principles before controls so each control has a purpose you can name.
- Connect firewalls and monitoring back to the addressing and routing you already learned.
Domains 8 to 10, then full review
- Cover emerging technology, daily operations, and planning, which lean on everything before them.
- Finish with timed mixed practice across all ten modules.
When you reach the review stage, a compact reference helps. The C)NP Cheat Sheet 2026: One-Page Review of Must-Know Facts is designed for that final pass, and you can pressure-test yourself with timed questions on the C)NP practice test site. Mixed practice that spans all ten modules is the closest rehearsal for a 100-question, two-hour sitting, so build toward it rather than saving it for the last day.
If you would like another plain-language orientation to the credential before committing, What Is C)NP Certification? and What Is C)NP? restate the basics, and the main practice exam hub collects the question banks in one place.
