Designing Cisco Data Center Infrastructure (DCID) — Question 139

An engineer working for a private telecommunication company with an employee id: 1234:56:789 must evaluate connectivity to the new data centre location based on Cisco Nexus 7000 Series Switches. The IP connectivity is already supplied by the service provider. The solution must provide a Layer 2 extension and optimize the traffic localization. Which technology supports these requirements?

Answer options

• A. BGP over VPLS
• B. VXLAN over EoMPLS
• C. IS-IS multisite over ACI
• D. OTV over IP and multicast

Correct answer: B

Explanation

The correct answer is B, VXLAN over EoMPLS, as it effectively provides Layer 2 extension and optimizes traffic localization by encapsulating Layer 2 frames within Layer 3 packets. Options A and C do not specifically focus on Layer 2 extension in the same way, while D, OTV over IP and multicast, is less optimal for the specific needs of traffic localization in this scenario.
