Refer to the exhibit. The following must be considered: -SW1 is fully configured for all traffic, -The SW4 and SW9 links to SW1 have been configured, -The SW4 interface Gi0/1 and Gi0/0 on SW9 have been configured, -The remaining switches have had all VLANs added to their VLAN database. Which configuration establishes a successful ping from PC2 to PC7 without interruption to traffic flow between other PCs?
