Craig, being the studious person he is, recently renewed his Cisco Certified Network Associate (CCNA) certification by passing the CCNA Security exam. These exams must be renewed every three years and this is the fourth time Craig has sat the exams. This time he passed the exam first attempt! Fortunately! In case you were wondering, Cisco is one of the largest networking hardware and software companies in the world which has a famous and respected series of networking courses and certifications hardworking IT people can learn and study. Well done Craig.
