One of the most common questions I hear is: "Where do I start with CCNA?" My answer is always the same: master networking fundamentals and IP addressing first, then move into routing and switching, and only then get into security and automation — which is exactly the order of the official exam blueprint.
A common mistake candidates make is jumping straight to memorizing commands without understanding why they're using them. My advice: always keep a real lab or simulator (like Packet Tracer) next to you and actually implement every concept.
