Refer to the exhibit. An engineer must design a solution that facilitates IP mobility and avoids hair pinning between DC1 and DC2 in an active/active data center design. The current environment implem

Configuring active HSRP on DC2, possibly alongside another active HSRP on DC1, does not inherently solve the hair-pinning problem for IP mobility across stretched subnets.

Implementing anycast gateways on both data centers ensures that a mobile host in a stretched subnet always uses its local gateway for default forwarding. This prevents traffic from being hair-pinned across the DCI to the remote data center's gateway, optimizing traffic flow and providing local egress for IP mobility.

Advertising host routes on both DCs would significantly increase routing table size and complexity, and does not inherently prevent hair-pinning for general subnet traffic or dynamic host movements.

Filtering stretched subnets on DC2 contradicts the requirement that both data centers advertise the stretched subnets to the WAN.
