What statements are NOT true regarding the network shown below?
A.
If Fa0/1.4 goes down WKS4 will not be able to contact the FTP server
B.
Collisions can occur between WKS4 and WKS5
C.
STP is running
D.
SW1 is the root bridge
E.
WKS 5 and WKS 3 are in the same network
Explanation:
WKS 5 and WKS 3 are NOT in the same network. WKS 5 is in VLAN 4 and WKS 3 is in VLAN 2. VLANs are configured as different subnets serviced by subinterfaces on the router. Each of the sub interfaces is a different subnet or different network.
It is true that if Fa0/1.4 goes down, WKS4 will not be able to contact the FTP server. WKS3 and the FTP server are in different VLANs, which means that if either of
the subinterfaces on the router servicing VLAN 3 or VLAN 4 go down, they not be able to connect, since all inter-VLAN communication goes through the router
using those subinterfaces. Since Fa0/1.4 services VLAN 4, where WKS4 is located if Fa0/1.4 goes down WKS4 will not be able to contact the FTP server.
It is true that collisions can occur between WKS4 and WKS5 since they are in the same VLAN and connected to a hub. If they were connected to a switch, collisions
would NOT be possible.
It is true that STP is running. It runs on the switches by default.
It is true that SW1 is the root bridge.Since the Fa0/1 port on SW3 is in a blocking state and STP rules call for forwarding on all ports that lead to the root bridge, then
SW2 cannot be the root bridge. Since all ports must be forwarding on the root bridge, that rules out SW3 as the root bridge, which mean SW1 must be the root
bridge.
