It was nearly 3 years to the day that I completed CCNA Security. So coming down to the expiration, I had to prepare to retake a previous exam or move onward and upward with another exam and certification. Obviously it makes sense to go up. I prepared for the CCNP Security SECURE 642-637 exam and passed! Part 1 of 4 tests to take to get the CCNP Security. Here I come!
