To help you prepare for the VCAP5-DCD exam, this section explains what a technical design is and why it is important to the end solution, what happens at each stage of the technical design process, and what should be produced as part of a technical design. These topics cover Section 1, “Create a vSphere conceptual design” from the VCAP5-DCD 5 blueprint.
This chapter is from the book

Technical design requires completely different skills from the troubleshooting and maintenance tasks commonly carried out by experienced IT professionals. The role of a technical designer or architect involves communication skills, technical knowledge, and a certain amount of artistic flare. This chapter will take you through the terminology and process of technical design. The concepts discussed here can be applied to any project, not just a VMware-related solution. By understanding and working with a design process, an engineer can integrate with other business and technical professionals and provide valued input to a business project.

“Do I Know This Already?” Quiz

The “Do I Know This Already?” quiz allows you to assess whether you should read this entire chapter or simply jump to the “Exam Preparation Tasks” section for review. If you are in doubt, read the entire chapter. Table 1-1 outlines the major headings in this chapter and the corresponding “Do I Know This Already?” quiz questions. You can find the answers in Appendix A, “Answers to the ‘Do I Know Already?’ Quizzes and ‘Q&A’ Chapter Review Questions.”
