Designing Cisco Data Center Infrastructure (DCID) — Question 52

An engineer must interconnect two geographically separated data centers. The service provider offers a Layer 2 Metro Ethernet link. The strict security policy requires that the information that is shared between two sites must be sent encrypted. The application deployed between two sites requires a line-rate throughput regardless of the packet size and speed.

Which solution meets these requirements?

Answer options

Correct answer: C

Explanation

The correct answer is MACsec because it provides encryption at Layer 2, which meets the security requirement while ensuring line-rate throughput. L2TPv2 and L2TPv3 are tunneling protocols that do not inherently provide encryption, and IPsec operates at Layer 3, which would not fulfill the requirement for Layer 2 encryption.
