With the rapid development of network, there is a growing of the demand for network engineers with an unprecedented rapid, and a soaring demand for educating and testing network engineers. So, how many CTP certification exams are in existence at present? How to take part in those exams?

Anyone who once took part in some kind of international certification exam should have heard about the test company Prometric. Prometric Examination Company is the largest international computerized test authentication services company, it has established 4000 Authorization Test Center (APTC) in the global, in charge of providing the IT Industry Certification Exam. This Company has set up a licensing Examination Center (ATPC) in major cities of many countries around the world, and is responsible for providing the IT industry certification examination, and provides candidates for certification examinations of World well-known IT Corporation, including: Microsoft, Oracle, Cisco, Sun HP, Linux, Adobe, IBM/Lotus, Intel, Lucent, SCO, Novell,Compaq……

CTP certification exams are carried out under the environment of computer network. CTP Company puts its own examinations questions into the test system of Prome-tric Company, and then Prometric produce different papers for each of the candidates. The speed of updating the existing knowledge is fast, therefore the examination item pool of CTP also updates with its produces updating.

To take CTP Certifications for an example, the examination form is divided into standardized test and adaptive test. Because the adaptive test is an item of new test technology, it makes the computer become not only the information receiver in the exam any more. It also has a certain degree of intelligence, ie it can decide the difficulty of the next question by real-time analysing of the examinee's current result, judging the examinee's knowledge scope and how much he has grasped. In the CTP tt0-201 examination, firstly providing a moderate degree of difficulty if the answer is correct, it will increase the degree of difficulty in the next question; if the answer is wrong, the next question would be easier; not allow checking the front of the subjects made. This examination largely avoided cramming and prevented test from leaking, and it really played a role in testing the examinees' understanding to the concepts, now more and more certification exams adopted this kind of exam form.

The IT certification exams at present are mainly choice questions(single,multiple and infinitives choice questions), scene, drag and experiment questions, also tt0-201 is no exception. You can instantly see your result as pass or no pass on the computer screen immediately when you finish your test, the transcript is thereafter printed, on which listed the assessment figure, letting you know the advantage and the disadvantage to make up for.
