QuestionQ113

Network Design

A company operates mission-critical infrastructure in one data center. Because of business growth, it intends to open additional data centers in the coming years. A network engineer must recommend a data center interconnection technology that enables scalability and seamless VM mobility, while delivering maximum security and fault isolation between data centers.

Which technology must be used to satisfy these requirements?

  • A TrustSec
  • B OTV
  • C CloudSec
  • D UDLD
Explanation

Overlay Transport Virtualization (OTV) extends Layer 2 networks between geographically separate data centers to support workload and VM mobility. It uses an overlay that isolates each site’s Layer 2 control-plane and fault domain, avoiding the extension of STP failures between data centers while supporting scalable interconnection.
