Designing Cisco Data Center Infrastructure (DCID) — Question 98
An engineer must interconnect two data centers to support the dynamic virtual machine migration. The data centers are currently interconnected using an IPv4 network. However, the data plane encapsulation of the underlay network is expected to change next year. To meet the VM migration requirement, the solution must track MAC route changes, update all other remote devices simultaneously and prevent excessive MAC flapping with broadcast and unicast traffic loops. The company must also use networking equipment from different manufacturers to prevent vendor-locking. Which solution meets these requirements?
Answer options
- A. EoMPLS
- B. OTV
- C. EVPN
- D. VXLAN
Correct answer: C
Explanation
The correct answer is EVPN because it provides a control plane for MAC address learning and allows for efficient handling of MAC route changes across a multipoint environment while preventing loops. Other options like EoMPLS and OTV do not offer the same level of flexibility and functionality for dynamic VM migration and MAC tracking, while VXLAN primarily focuses on encapsulation without the advanced control plane features that EVPN provides.
