A practice test simulates the actual test and aims to provide you with the optimal preparation for what to expect on the real exam. A MeasureUp practice test includes around 150 questions covering the exam objective domains. In a MeasureUp practice test there are two possible test-taking modes to prepare students for their certification: Certification Mode and Practice Mode.
- The Practice Mode lets users highly customize their testing environment. You can select how many questions they want to include in the assessment, the maximum time to finish the test, the possibility to randomize the question order, and select how and which questions will be shown in the test.
- The Certification Mode simulates the actual testing environment users will encounter during a certification exam. They are timed and do not let users request the answers and explanations to the questions until the end of the test.

How to use the CompTIA Data+ Practice Test?
You can use the CompTIA Data+ practice test in two different modes: certification and practice mode. The former gives you the possibility to assess your knowledge and discover your weak areas, and the latter allows you to focus on these areas, ensuring you spend your time wisely. We recommend you initially take the DA0-001 Data+ practice test in certification mode. By studying the generated report on completing the test, you will get a helpful overview of which areas require further attention. You should then take the test in practice mode in order to improve in those areas. Once you are confident you have developed your knowledge in those areas, you can re-take the test in certification mode and, on passing two consecutive times with a score of 90%, you know you are exam ready!
CompTIA DATA+ CERTIFICATION EXAM
