In the network shown in the figure, adjacent routers use directly connected interfaces to establish EBGP neighbor relationships. The Router ID of each device is 10.0.XX, and the AS number is 6500X, where X is the router number. R1 and R4 both have static routes to 192.168.1.0/24, which are imported into BGP. R3 configures the "peer yyyy as-path-filter 1 import" command for all neighbors. Which of the following can enable R3 to select the longest AS-Path to 192.168.1.0/24?
