About the AuthorAt the impressionable age of 14,William “Bo” Rothwellcrossed paths with aTRS-80 Micro Computer System (affectionately known as a “Trash 80”). Soonafter, the adults responsible for Bo made the mistake of leaving him alone withthe TSR-80. He immediately dismantled it and held his first computer class,showing his friends what made this “computer thing” work. Since that experi-ence, Bo’s passion for understanding how computers work and sharing thisknowledge with others has resulted in a rewarding career in IT training. Hisexperience includes cloud, Linux, UNIX, IT security, DevOps, and program-ming languages such as Perl, Python, Tcl, and BASH. He is the founder andlead instructor of One Course Source, an IT training organization.DedicationTo my sister, Betsy, who I tormented so much growing up. I’m glad that nowwe are adults you have either forgotten or forgiven my misdeeds.To my parents: 99.7 percent of the time Betsy confessed and got in trouble,it was really me.To my childhood dog, Hansel, thank you for always being there, under thedining room table, when I needed vegetables to disappear from my plate.You learned to chew silently, and for that, I was grateful.To my seventh-grade homeroom teacher, you know who you are.You said I was lazy and would never amount to anything. If you are reading this now,you have concrete proof in your hands that you were mistaken.AcknowledgmentsI always worry when I write this section that I will miss someone who hashelped me with this book. It takes a team to write a book, but often the authorgets all of the credit. For all of the editors and support staff who have helpedmake this book possible, thank you very much.Humble Bundle Pearson Networking and Security Certification Bundle – © Pearson.

xxviiiCompTIA®Cloud+ CV0-003 Exam CramArriving at the Exam LocationAs with any examination, arrive at the testing center early (at least 15 minutes).Be prepared! You need to bring two forms of identification (one with a pic-ture). The testing center staff requires proof that you are who you say you areand that someone else is not taking the test for you. Arrive early, because ifyou are late, you will be barred from entry and will not receive a refund for thecost of the exam.You’ll be spending a lot of time in the exam room. Plan on using the full 90 minutesallotted for your exam and surveys. Policies differ from location to location regard-ing bathroom breaks. Check with the testing center before beginning the exam.ExamAlertIn the Testing CenterYou will not be allowed to take into the examination room study materials oranything else that could raise suspicion that you’re cheating. This includespractice test material, books, exam prep guides, or other test aids. The TestingCenter will provide you with scratch paper and a pen or pencil. These days,this often comes in the form of an erasable whiteboard.Examination results are available after the exam. After submitting the exam,you will be notified whether you have passed or failed. The test administratorwill also provide you with a printout of your results.About This BookThe ideal reader for anExam Crambook is someone seeking certification.However, it should be noted that anExam Crambook is a very easily readable,rapid presentation of facts.
