دانلود کتاب VMware – مرکز داده حرفه ای معتبر – مجازی سازی در vSphere 6.7 – امتحان 2V0-21.19

Why should you learn about VMware vSphere? Although the concept of virtualization has been around since the days of mainframe computing, VMware was and is the company that made virtualization a mainstay in the x86/x64 space. Originally, VMware introduced a desktop virtualization product called Workstation followed by the server virtualization products GSX and ESX and a datacenter management product called VirtualCenter. Today, the ESX and VirtualCenter products have converged into the vSphere platform. This platform allows IT administrators to get greater utilization out of existing physical servers and reduce the overall datacenter footprint, sometimes by 50 percent or more. It also provides features to allow for high availability and scaling up with a predictable level of performance. Today, vSphere is used by 100 percent of Fortune 500 companies and distributed by over 75,000 partners.1 This means that if you intend to get a job in the IT space, whether you are working for a large organization or a big partner, you are likely to be working with vSphere. Because of this, companies look for individuals who are certified. Holding the VMware certification lets companies know that you are qualified to work with vSphere at a guaranteed level of competency. The purpose of this book is to help you pass the Professional VMware vSphere 6.7 (2V0-21.19) exam, exam number 2V0-21.19. The exam is closely tied to a version of vSphere. This book focuses on vSphere 6.x (6.5, 6.7). The current version of the certification, VMware Certified Professional – Data Center Virtualization 2020 (VCP-DCV 2020), is based on the 6.7 release of vSphere and covers installation, configuration, and administration. VMware’s information about the exam is posted at www.vmware.com/education-services/certification/ vcp6-7-dcv-exam.html This book covers all of the objectives tested for in the exam and includes topical information, lab work, and review questions. Because this book covers many of the tasks an administrator would perform on a day-to-day basis, this book should remain a useful reference even after you have passed the exam and earned your certification.
