Coming from a Cisco background, switching to Juniper was quite a challenge for me. The question bank had plenty of practice with clear explanations, and the scenario questions really strengthened my analytical skills. I felt a lot of pressure on exam day, but my score turned out surprisingly high. Highly recommended.
