This chapter covers the following exam topic:

Describe Device Virtualization

There are two types of device virtualization when it comes to Nexus devices. The first is how to partition one physical switch and make it appear as multiple switches, each with its own administrative domain and security policy. That approach has its own benefits and business requirements.

The other option is how to make multiple switches appear as if they are one big modular switch. That approach has its own benefits and business requirements, too. This chapter covers the virtualization capabilities of the Nexus 7000 and Nexus 5000 switches using Virtual Device Context (VDC) and Network Interface Virtualization (NIV).

“Do I Know This Already?” Quiz

The “Do I Know This Already?” quiz enables you to assess whether you should read this entire chapter thoroughly or jump to the “Exam Preparation Tasks” section. If you are in doubt about your answers to these questions or your own assessment of your knowledge of the topics, read the entire chapter. Table 3-1 lists the major headings in this chapter and their corresponding “Do I Know This Already?” quiz questions. You can find the answers in Appendix A, “Answers to the ‘Do I Know This Already?’ Quizzes.”

CAUTION

The goal of self-assessment is to gauge your mastery of the topics in this chapter. If you do not know the answer to a question or are only partially sure of the answer, you should mark that question as wrong for purposes of the self-assessment. Giving yourself credit for an answer you correctly guess skews your self-assessment results and might provide you with a false sense of security.
