CompTIA A Certification ExamObjectivesExam Number: 220-901IntroductionIn order to receive CompTIA A certification a candidate must pass two exams. The first exam isCompTIA A 220-901 Certification Exam. The CompTIA A 220-901 examination measures necessarycompetencies for an entry-level IT professional with the equivalent knowledge of at least 12 months ofhands-on experience in the lab or field.Successful candidates will have the knowledge required to: Assemble components based on customer requirements Install, configure and maintain devices, PCs and software for end users Understand the basics of networking and security/forensics Properly and safely diagnose, resolve and document common hardware and software issues Apply troubleshooting skills Provide appropriate customer support Understand the basics of virtualization, desktop imaging, and deploymentCompTIA A is accredited by ANSI to show compliance with the ISO 17024 Standard and, as such,undergoes regular reviews and updates to the exam objectives. The following CompTIA A 220-901 examobjectives result from subject matter expert workshops and industry-wide survey results regarding the skillsand knowledge required of an entry-level IT professional. The percentages in this document represent therelative importance of the subject areas (domains) in the associated body of knowledge, and togetherestablish the foundation of an entry-level IT professional.This examination blueprint includes domain weighting, test objectives, and example content. Exampletopics and concepts are included to clarify the test objectives and should not be construed as acomprehensive listing of all the content of this examination.Candidates are encouraged to use this document to guide their studies.
