  1. "Do I Know This Already?" Quiz
  2. Foundation Topics
  3. Exam Preparation Tasks

Chapter Description

This chapter covers enterprise data center design fundamentals, technology trends, and challenges facing the data center to assist in preparation for the Cisco CCDA 640-864 exam.

This chapter covers the following subjects:

  • Enterprise DC Architectures
  • Challenges in the DC
  • Enterprise DC Infrastructure
  • Virtualization Overview
  • Virtualization Technologies
  • Network Virtualization Design Considerations

This chapter covers enterprise data center design fundamentals, technology trends, and challenges facing the data center. General data center architecture, components, and design considerations are examined, but detailed data center design is not covered.

This chapter also provides an overview of virtualization, discusses the various virtualization technologies and network virtualization design considerations.

The CCDA candidate can expect plenty of questions related to data center fundamentals, challenges, architecture, and virtualization.
