Advice to get certified in NSE4

Hi everyone

I’ll be taking over a firewall at work soon, even though I haven’t worked with one hands-on before. Right now, I have read-only access to get familiar with the system before officially starting.

My course starts next week, and I’m planning to go for NSE5 after that, so I want to make sure I’m on the right track from the beginning. How was your experience with the course and the exam? What should I focus on?

Any advice from real experience would be really appreciated!
