Which validated design approach explicitly addresses this dual-stack transition requirement using a three-tier campus architecture, SD-WAN, and Firepower?

A Deploy an IPv6-only three-tier architecture and immediately decommission all IPv4 infrastructure
B Use a three-tier Cisco architecture with Cisco SD-WAN and Cisco Firepower to support IPv6-only clients while maintaining dual-stack infrastructure for IPv4 client transition
C Convert the WAN to SRv6 to eliminate the need for any IPv4 addressing
D Migrate all clients to the Meraki dashboard before enabling any IPv6 addressing
