One thing that many of these exams have in common is that they were built Visual Certification Exam software and used VCE files. A lot of companies use this model to certify technical workers – Microsoft, Cisco, SeaChange, CompTIA, Nortel and many others.Īll of the exams follow roughly similar formats: you sit in front of a computer in a testing room with exam proctors, and answer multiple-choice questions about the subject of the certification. Many of us have taken IT certification courses so that we could take those exams and get those coveted certifications with which to build our IT careers.
