Quick Answer

The correct answer is to apply the crypto map to the interface as the final step. This order is technically required because the crypto map acts as the binding policy that ties together the IKE Phase 1 parameters, the IPsec transform set for Phase 2, and the crypto access control list (ACL) that defines which traffic is interesting. You must first define the IKE policy to establish the secure tunnel, then the transform set for encryption and hashing, followed by the crypto ACL to match the traffic, and then the crypto map to combine these elements; only after all components are assembled can the map be applied to the outgoing interface to activate the VPN. On the ENCOR 350-401 exam, this drag-and-drop question tests your understanding of the logical sequence of IPsec site-to-site VPN configuration steps, and a common trap is placing the crypto ACL before the transform set or forgetting that the crypto map application is the final action. A useful memory tip is to think of building a house: first set the foundation (IKE policy), then the walls (transform set), then the door (crypto ACL), then the lock (crypto map), and finally install the lock on the door (apply to interface).
