Cisco ICND1 v3 CCNA: 5 Essentials Before You Start

Jumping into networking with a Cisco-focused course can seem like a direct path to IT skills. Many learners choose the Alison Diploma in Interconnecting Cisco Networking Devices Part 1 (ICND1) v3 CCNA expecting it to be a shortcut to the official CCNA certification or a fast track to a job. But enrolling without checking the details can lead to missed expectations—especially since the Cisco exam this course covers was retired years ago.

This article explains the five most important facts to know before you begin. You’ll see where the course fits in today’s Cisco landscape, what you actually learn, and how the Alison diploma compares to official Cisco certification.

What to Confirm About the Alison ICND1 v3 CCNA Course

1. The Exam Covered Is Now Retired

Many expect this course to prepare them for the current Cisco CCNA certification. In reality, the Alison course covers the ICND1 (exam 100-105), which was retired by Cisco on 24 February 2020. The current exam is CCNA 200-301, which combines both ICND1 and ICND2 content into a single test.

What to do: If your goal is official CCNA certification, use this course as a foundation but check Cisco’s official site for the latest exam topics and requirements. You’ll need to study additional material to cover the current CCNA (200-301) exam.

2. The Alison Diploma Is Not an Official Cisco Certification

Expectation: Some learners think completing this course means they are “CCNA certified” or that the Alison diploma has the same value as Cisco’s own credential.

Reality: The Alison diploma is a recognition of course completion, not an official Cisco qualification. Passing the real CCNA exam requires registering and paying for the test at an authorised Cisco exam centre. The Alison diploma is not accredited by Cisco and does not grant you the CCNA title.

What to do: Use the Alison diploma to show you have studied the basics, but always clarify its independent status if asked by employers or clients.

3. Content Focuses on Networking Fundamentals, Not Advanced Practice

The course is best for those new to networking or wanting a structured introduction to Cisco concepts. It covers:

• Building simple networks and understanding the host-to-host model
• LANs, switches, ethernet, and troubleshooting media issues
• TCP/IP layers, IP addressing, subnets, and static routing
• Device security basics, VLANs, DHCP, OSPF, RIPv2, and an introduction to IPv6

Expectation: Some expect hands-on labs or advanced configuration.

Reality: The content is mostly video-based, with theory and basic command-line examples. There are no live labs or simulated exam environments.

What to do: If you already have networking experience or need advanced Cisco lab practice, look for more hands-on resources or Cisco’s own learning platform.

4. Studying Is Free, but the Diploma Is Paid

You can access all course materials at no cost, including videos and assessments. However, if you want a formal diploma as proof of completion, there is a fee.

• Study: Free on Alison, including via the Alison app (offline study supported)
• Diploma: Paid and optional; not a professional qualification

What to do: Decide if you need the diploma for your CV or personal records. If not, you can still complete the course and gain the knowledge for free. Go to the official course page.

5. Who Should—and Should Not—Take This Course

Best for: Beginners in IT, those considering a networking career, or anyone wanting to understand Cisco basics before committing to the official CCNA path.

Not for: Those seeking direct CCNA certification, advanced Cisco configuration, or guaranteed job outcomes. If you already know how to configure VLANs, OSPF, or IPv6 on real equipment, this course will feel too basic.

Tip: If you want to continue, Alison also offers Part 2 (ICND2), but remember both parts follow the old exam structure.

Key Concepts: Networking Devices, Protocols, and Where They Matter

Networking is about connecting devices—computers, switches, routers—so they can communicate efficiently and securely. At the heart of this are protocols like TCP/IP, which define how data moves across networks, and devices like switches (which connect devices within a local network) and routers (which connect different networks together).

Understanding the OSI model helps you see how data is packaged, transmitted, and received at each layer—from physical connections (cables and switches) up to applications (like web browsers). VLANs allow you to segment a network for better security and efficiency, while protocols like OSPF and RIPv2 help routers decide the best path for data.

Security is also a core part of networking. This means not just passwords, but configuring access control lists (ACLs), using SSH for secure management, and hardening devices against threats. IPv6 is the next generation of internet addressing, and knowing its basics is increasingly important as networks grow.

Is This Course Right for You? Next Steps

The Alison Diploma in Interconnecting Cisco Networking Devices Part 1 (ICND1) v3 CCNA is a solid introduction to networking and Cisco concepts for beginners. It is not a shortcut to the official CCNA certification, nor does it replace hands-on lab experience. If you are exploring IT, want to understand how networks work, or are preparing for further study, this course is a good starting point.

After finishing, consider moving on to more advanced courses or official Cisco resources that align with the current CCNA (200-301) exam. Always check the latest requirements on Cisco’s website before planning your certification path.

Note: The Alison diploma is not an official professional qualification and does not grant Cisco certification status.
