Designing Cisco Data Center Infrastructure (DCID) — Question 111
A company runs mission-critical infrastructure in a single data center. Due to business growth, it plans to open more data centers in the coming years. A network engineer is asked to recommend a network technology for data center interconnection that allows scalability and seamless VM mobility while providing maximum security and fault isolation between data centers.
Which technology must be used to meet these requirements?
Answer options
- A. TrustSec
- B. OTV
- C. CloudSec
- D. UDLD
Correct answer: B
Explanation
The correct answer is B, OTV (Overlay Transport Virtualization), as it facilitates the interconnection of multiple data centers while allowing for scalability and seamless virtual machine migration. Unlike TrustSec, CloudSec, and UDLD, which serve different functions, OTV specifically addresses the requirements of secure, scalable data center interconnections.
