Common Mistakes to Avoid

1. Underestimating ENCOR breadth. It covers more than you expect
2. Skipping automation. It’s 15% and growing in importance
3. Weak BGP understanding. It’s critical for enterprise networks
4. Not enough lab time. Simulation isn’t optional

The Bottom Line

CCNP Enterprise requires significant commitment—200+ study hours, $700+ in exam fees, and deep hands-on practice. But it establishes you as a senior network professional capable of handling enterprise-scale infrastructure.

Start with ENCOR, build extensive lab experience, and choose a concentration that aligns with your career goals. Your senior networking career accelerates here.
