Refer to the exhibit.
Which two options are the number of broadcast domains and collision domains shown in the
exhibit? (Choose two.)
A.
1 collision domain
B.
2 collision domains
C.
4 collision domains
D.
7 collision domains
E.
1 broadcast domain
F.
2 broadcast domains
G.
4 broadcast domains
H.
7 broadcast domains
why?
There are 2 Ethernet switches separated by a router. Routers do not forward broadcast traffic so broadcast packets originated on the switch on the left side will not be seen on the switch of the right side and vice versa. That is why there are two 2 broadcast domains in this network topology. We can assume that all the devices connected to each switch are in the same broadcast domain. There is a server and 2 workstations on the left side and one server and one workstation on the right side.
Each Ethernet port is by itself a collision domain. Collision occurs when two devices try to transmit at the same time. Both devices detect the collision and waits a random amount of time and retries until successful in getting the transmission sent. The port can be configure to full duplex (allowing to each device in a connection to receive and transmit at the same time). Because this network diagram don’t say the ports in the switch or the router are configure for full duplex, we can assume they are in default duplex setting which is half duplex (Half-duplex devices let you send and receive, but only one-way at a time). That is why each port in the switch is a collision domain. (7 collision domains).
Hope this help.
