u want to secrease the amount of time it takes for switch ports on swA to begin forwarding. port fast isn't configured on any of the sw ports pn switchA. u have the spanning tree portfast default cmd from gobal config mode.
which of the ports on swA will use portFast?
a. none, bcz portfast can't b enabled globally b. all ports
c. all access ports d. all trunk ports. a. root bridge = sw3
sw1: g0/1-> D; g0/1->R; g0/2-> D
sw2: g0/1-> N; g0/2->R; g0/0->N
sw4: g0/0-> R
sw4: g0/1-> D
remember that each collision domain must have a single STP designated port. b. root bridge = sw2
sw1: g0/1-> D; g0/1->R; g0/2-> D
sw3: g0/1-> N; g0/2->R; g0/0->N
sw4: g0/0-> R
sw4: g0/1-> D.
