Tips for Taking Your Cloud+ Exam
The CompTIA Cloud+ exam contains 100 multiple-choice questions and must be completed in 90 minutes or less. This information may change over time, and we advise you to check www.comptia.org for the latest updates.
Many questions on the exam offer answer choices that at first glance look identical, especially the syntax questions. Remember to read through the choices carefully because close just doesn’t cut it. If you get information in the wrong order or forget one measly character, you may get the question wrong. Many of the questions will be presented in a scenario format that can be a long, involved statement that is designed to confuse or misdirect you. Read these questions carefully and make sure you completely understand what is being asked. It is important to filter out irrelevant statements in scenario questions and focus on what they are asking you to identify as the correct answer. So, to practice, do the practice exams and hands-on exercises from this book’s chapters over and over again until they feel natural to you. Do the online sample test until you can consistently answer all the questions correctly. Relax, read the question over and over until you are 100 percent clear on what it is asking, and then you can usually eliminate a few of the obviously wrong answers.
Here are some general tips for exam success:
- Arrive early at the exam center so you can relax and review your study materials.
- Read the questions carefully. Don’t jump to conclusions. Make sure you’re clear about exactly what each question asks. “Read twice, answer once!” Scenario questions can be long and contain information that is not relevant to the answer. Take your time and understand what they are really asking you.
- Ask for a piece of paper and pencil if it is offered to take quick notes and make sketches during the exam.
- When answering multiple-choice questions that you’re not sure about, use the process of elimination to get rid of the obviously incorrect answers first. Doing this greatly improves your odds if you need to make an educated guess.
After you complete an exam, you’ll get immediate, online notification of your pass or fail status, a printed examination score report that indicates your pass or fail status, and your exam results by section. (The test administrator will give you the printed score report.) Test scores are automatically forwarded to CompTIA after you take the test, so you don’t need to send your score to them. If you pass the exam, you’ll receive confirmation from CompTIA and a package in the mail with a nice document suitable for framing showing that you are now a Cloud+ certified professional!
