• Master VMware VCAP5-DCA exam topics
• Assess your knowledge with chapter-opening quizzes and review tasks
• Review key concepts with exam preparation tasks
• Prepare and practice with realistic exam scenarios
The VCAP5-DCA Official Cert Guide focuses specifically on the objectives for the VMware Certified Advanced Professional 5–Data Center Administration. VMware Certified Instructors (VCI) Steve Baca and John A. Davis share preparation hints and test-taking tips, helping you identify areas of weakness and improve both your conceptual knowledge and hands-on skills. Material is presented in a concise manner, focusing on increasing your understanding and retention of exam topics.
This Official Cert Guide comes with access to one set of original practice scenarios designed to prepare you for the experience of the real exam and get you comfortable executing the scenarios in order to complete them in the limited amount of time during the actual test. Content in the practice scenarios maps to the VCAP blueprint and is relevant to both the VDCA510 and VDCA550 exams. All the scenarios are based on real-world experiences, where administration tasks that are covered by the exam, may need to be applied.
Well-regarded for its level of detail, assessment features, comprehensive design scenarios, and challenging review questions and exercises, this official study guide helps you master the concepts and techniques that will allow you to succeed on the exam the first time.
The VCAP5-DCA Official Cert Guide is part of a recommended learning path from VMware that includes simulation and hands-on training from authorized VMware instructors and self-study products from VMware Press.
