Question
Company A has engaged a network architect to design a robust redundancy strategy for their primary data center. The company wants to implement an active/active configuration within the data center and establish a disaster-recovery site that can take over operations in case of major disruption at the primary data center. The company has these requirements:
- The solution must ensure high availability and minimize the risk of
downtime.
- The solution must ensure data synchronization and consistency between
the primary and disaster-recovery sites.
- The desired RTO is less than 4 hours, and the RPO is no more than 15
minutes.
- The solution must follow RFC 7348 principles.
Which solution meets the requirements?
Options
- AImplement OTV to provide seamless migration of virtual machines workload distribution across
- BImplement a Geneve-based overlay to replicate all storage data to a remote backup site to ensure
- CImplement DMVPN phase 3 to establish a secure channel between the data centers.
- DImplement a VXLAN-based overlay to provide network virtualization, segmentation, flexibility, and

Explanation
RFC 7348 defines VXLAN. A VXLAN-based overlay provides the network virtualization and segmentation needed for an active/active primary data center design and scalable interconnect patterns, while enabling consistent tenant/VRF/VNI constructs across the primary and DR sites- supporting the high-availability objective and operational flexibility required to meet the stated recovery targets.
