Passing CCNA without touching configurations is very difficult. The exam may be theory-based, but the blueprint assumes you have spent time on the CLI. Fortunately, you do not need a full rack of routers and switches at home. With modern simulation and virtualization tools, you can build powerful labs on a single laptop or use cloud-based environments.
The key is to understand the strengths and limits of each platform and choose the combination that fits your budget and learning style.
Cisco Packet Tracer is often the first tool CCNA candidates encounter. It is easy to install, runs on modest hardware and includes many CCNA-level features:
Use Packet Tracer for quick experiments, especially when learning new topics. You can drag and drop devices, connect them and observe behavior in minutes. However, remember that it is still a simulator, not real IOS. Some advanced features are not available or behave slightly differently from production devices.
When you want more realism and flexibility, tools like GNS3 and EVE-NG allow you to run actual IOS images or modern virtual appliances. They require more CPU, RAM and disk space, but they bring you much closer to what you will see in real networks.
For CCNA, you can use these platforms to build multi-router topologies, practice routing protocols, test ACLs and experiment with more realistic scenarios than Packet Tracer alone.
If you prefer not to manage virtual infrastructure yourself, cloud labs are a strong option. PASS EXAM’s lab environments, for example, provide:
Many learners adopt a hybrid approach: Packet Tracer for fast everyday practice, a local virtual environment for deeper experiments and cloud labs for structured, exam-aligned tasks.
There is no single “best” CCNA lab platform. Instead, ask yourself:
Start simple, then expand as your skills and ambitions grow. The most important factor is not which platform you choose, but how consistently you use it.
Get access to CCNA-ready lab topologies and step-by-step exercises that accelerate your hands-on skills.
