The Company LAN is becoming saturated with broadcasts and multicast traffic. What could you
do to help a network with many multicasts and broadcasts?
A.
Creating smaller broadcast domains by implementing VLANs.
B.
Separate nodes into different hubs.
C.
Creating larger broadcast domains by implementing VLANs.
D.
Separate nodes into different switches.
E.
All of the above.
Explanation:
Controlling broadcast propagation throughout the network is important to reduce the amount of
overhead associated with these frames. Routers, which operate at Layer 3 of the OSI model,
provide broadcast domain segmentation for each interface. Switches can also provide broadcast
domain segmentation using virtual LANs (VLANs). A VLAN is a group of switch ports, within a
single or multiple switches, that is defined by the switch hardware and/or software as a single
broadcast domain. A VLANs goal is to group devices connected to a switch into logical broadcast
domains to control the effect that broadcasts have on other connected devices. A VLAN can be
characterized as a logical network.
