    • CompTIA Cloud+ Certification Exam Objectives 1 of 17Copyright ©2012 by the Computing Technology Industry Association. All rights reserved.The CompTIA Cloud+ Certification Exam Objectives are subject to change without notice.Certification Exam DraftObjectives: Cloud+ Beta Exam(CV1-001) Live Exam (CV0-001)INTRODUCTIONThe CompTIA Cloud+ certification is an internationally recognized validation of theknowledge required of IT practitioners working in cloud computing environments.Test Purpose: This exam will certify that the successful candidate has the knowledge andskills required to understand standard Cloud terminologies/methodologies, to implement,maintain, and deliver cloud technologies and infrastructures (e.g. server, network,storage, and virtualization technologies), and to understand aspects of IT security and useof industry best practices related to cloud implementations and the application ofvirtualization.It is recommended for CompTIA Cloud+ candidates to have the following:• CompTIA Network+ and/or CompTIA Storage+ Powered by SNIA, thoughCompTIA certifications are not required.• Have at least 24-36 months of work experience in IT networking, networkstorage, or data center administration.• Familiarity with any major hypervisor technologies for server virtualization,though vendor-specific certifications in virtualization are not required.The table below lists the domains measured by this examination and the extent to whichthey are represented.Domain % of Examination1.0 Cloud Concepts and Models 12%2.0 Virtualization 19%3.0 Infrastructure 21%4.0 Resource Management 13%5.0 Security 16%6.0 Systems Management 11%7.0 Business Continuity in the Cloud 8%Total 100%**Note: The bulleted lists below each objective are not exhaustive lists. Even though they arenot included in this document, other examples of technologies, processes or tasks pertaining toeach objective may also be included on the exam.(A list of acronyms used in these objectives appears at the end of this document.)
