It is not really a requirement for future certification exam takers to undergo actual training to gain knowledge and expertise on a specific area that they would like to pursue on getting. Some considers reading books as an actual training in itself, or most would agree that experience will always be the best teacher. Hands on experience will give you an edge over other candidates since more or less, constant exposure will make room for learning and at certain extent, develop the skill sets needed to prepare you for the actual certification exam.
On the other hand, there are still some who finds classroom training more effective. For the average group of individuals who are still advocates of training can rely on training courses offered either trainer-led or online tutorials. Take CompTIA network training for example, wherein there are a lot of web sites that cater to those interested applicants preparing for their CompTIA Network+ exam. Topics discussed include major networking system technologies and terminologies, skills and tools that can be used on modern computer networks. It will also be an advantage if CompTIA Network+ trainees already studied basic Windows or equivalent topics to help them to easily grasp what the trainer is trying to discuss.
Usually, CompTIA network training courses should be delivered in such a way that students will be equipped with the right information to resolve potential networking issues that they may encounter in the future. Aside from taking up training courses, a CompTIA Network+ wannabe can also take advantage of different techniques such as taking up practical tests that can be used to assess his or her readiness in taking the exam.
