To create its highly regarded networking information products, Certification Zone has always relied on a skilled group of world-class experts, who are certified and experienced, to write and develop our Cisco certification preparation products. Instead of using just one or two networking professionals to address the multitude of topics addressed on Cisco's certification exams, Certification Zone finds experts in each topic who have hands-on field experience with the technologies they cover for our site.
