CompTIA A+ Certification Exam Objectives Exam Number: 220-901 Introduction In order to receive CompTIA A+ certification a candidate must pass two exams. The first exam is CompTIA A+ 220-901 Certification Exam. The CompTIA A+ 220-901 examination measures necessary competencies for an entry-level IT professional with the equivalent knowledge of at least 12 months of hands-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 deployment CompTIA 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 exam objectives result from subject matter expert workshops and industry-wide survey results regarding the skills and knowledge required of an entry-level IT professional. The percentages in this document represent the relative importance of the subject areas (domains) in the associated body of knowledge, and together establish the foundation of an entry-level IT professional. This examination blueprint includes domain weighting, test objectives, and example content. Example topics and concepts are included to clarify the test objectives and should not be construed as a comprehensive listing of all the content of this examination. Candidates are encouraged to use this document to guide their studies. The table below lists the domains measured by this examination and the extent to which they are represented. The CompTIA A+ 220-901 exam is based on these objectives. Domain Percentage of Examination 1.0 Hardware 34% 2.0 Networking 21% 3.0 Mobile Devices 17% 4.0 Hardware & Network Troubleshooting 28% Total 100% CompTIA A+ 220-901 Certification Exam Objectives version5 2 of 25 Copyright © 2015 by the Computing Technology Industry Association.
