Hi there mate! This is Nick, I observed that I was not able to modify my first blog post and that is the reason why I am here trying to explain. Anyways, there will be some modifications on how I will write my blog post since I just recently passed the CCNA exam. First, the topics that I am going to explain covers CCNA basic and fundamentals up to CCNP level. Yes, it is the official start of my journey to CCNP route, switch and TSHOOT. Also I will cover some of the requests of followers if I have time. Below is the picture of my exam result to motivate everyone.
