BPDU guard can be utilized along with PortFast to shut down ports when a switch is connected to the port. E . None of the other alternatives apply

A . The switch will ignore VTP summary advertisements B . The switch will forward VTP summary advertisements C . The switch will process VTP summary advertisements D . The switch will originate VTP summary advertisements E . The switch will create, modify and delete VLANs for the entire VTP domai

A . to make VTP easier to implement B . to isolate broadcast traffic C . to increase the size of the collision domain D . to allow more devices to connect to the network E . to logically group hosts according to function F . to increase network security

A . Switch A ,because it has the lowest MAC address B . Switch C,because it has the lowest priority C . Switch B,because it has the highest MAC address D .
