Designing Cisco Data Center Infrastructure (DCID) — Question 45

An engineer must use OTV for Layer 2 connectivity between data centers to support virtual machine mobility between the customer sites. To support this requirement, the engineer must ensure the existence of the same default gateway on both sites. Additionally, the operations team reports high bandwidth utilization on site A and wants to optimize the outbound traffic flows to use a local DC exit point.

Which feature must be used to meet these requirements?

Answer options

Correct answer: B

Explanation

The correct answer is B, FHRP filter, as it allows for the optimization of outbound traffic flows by filtering certain traffic types, thus reducing bandwidth utilization. Options A (data group) and C (ARP filter) do not address the need for managing high bandwidth and outbound traffic optimally. Option D (control group) is not relevant to Layer 2 connectivity or bandwidth optimization in this context.
