Data+ question types
- [Instructor] The Data+ exam contains two different types of questions, standard multiple choice questions, and some specialized performance-based questions. Let's look at each of these two categories. The multiple choice questions are usually pretty straightforward. For most of them, you'll simply be presented with a fact-based question, such as the one shown here and asked to choose a correct answer from four possible choices. The second type of question you'll face is the performance based question. On some CompTIA exams, like the A+ exam, you might be asked to perform a task on a simulated computer system. Fortunately, the data plus exam doesn't currently include these tasks. Instead, you'll find questions where you're asked to drag items into the right order, sort things by category, indicate different components of a data analysis, or perform similar vendor agnostic tasks. When you're answering exam questions, remember to use solid test taking strategies. Here are a few pointers. First, read the question very carefully. Pay attention to exactly what the question is asking, and remember that one or more of the wrong answers may based upon common misinterpretations of the question. Don't get tricked by the exam because you didn't read the question closely enough. Second, read all of the answer choices before you commit to the correct one. If you're unsure of the correct answer, try to eliminate one or more of the answers that you think are obviously incorrect. If you can eliminate two of the answer choices, you just improved your odds of getting that question correct from one in four to 50-50. Third, answer every question, even if you have no idea what the question is asking you. There's no penalty for guessing on the exam, so you might as well give some answer for every question. Fourth, the exam software offers you the ability to move back and forth between questions and revisit those that you're unsure of. You can mark questions that you'd like to review later. Be sure to use that feature. If you're not confident in your answer, go back later and give it another read. Finally, make at least three passes through the exam during your 90 minutes. Taking a quick first run through the exam and knocking out the easy questions will build your confidence and help you get a feel for the contents of the entire exam. I've heard from many test takers that they've encountered exams where all the performance-based questions appeared in the beginning of the exam. If you don't do a quick pass through the entire exam, you might become very discouraged because these performance-based questions tend to be more difficult and time consuming. It's absolutely fine to just skip them entirely during your first pass. During your second run through, try to answer every question on the exam. Then your third pass will help you clean up any errors that you made. Answering other questions during the first and second passes might also jog your memory and help you answer questions that were sticking points earlier in the exam.
