Yes, but practice. When I took the exam about half of the questions were related to tcp/ip in some form or another. It really helps if you have several routers to play with.
No problem mate, im glad i can help.
Make sure you cover every lab on end of every chapter, it will help you grasp the basics under your belt.
Now, offtopic, but i need some clarification:How much is worth of MTCNA? I have my CCNA’s on routing and security, i thought about getting Mtik cert tracks, but in my country at least, i get the opinion that this cert is not as valuable as other vendors.Is it me or it is true-ish?
