A hybrid company uses Direct Connect with a single Site-to-Site VPN backup and is migrating to IPv6 by moving to dual-stack. They require a backup connectivity option to always be present. Which combination of steps will migrate the data center connectivity to support IPv6 in the least time? (Choose two.)

The company needs to support IPv6 with a backup option and minimize downtime. Adding an IPv6 peer to the existing Direct Connect virtual interface (VIF) allows the Direct Connect connection to carry IPv6 traffic without creating a new VIF, which would require more configuration and potential downtime. Provisioning a new Site-to-Site VPN tunnel specifically for IPv6 traffic provides the necessary IPv6 backup connectivity. This approach allows for a phased migration, keeping the existing IPv4 connections active while the new IPv6 paths are established. Creating a new dual-stack Site-to-Site VPN and deleting the old one would cause a service interruption. Associating a new dual-stack public VIF would require reconfiguring the Direct Connect connection, leading to more downtime than simply adding an IPv6 peer. Encapsulating IPv6 in IPv4 VPN tunnels is not a standard or efficient way to migrate to dual-stack and adds unnecessary overhead.
