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.
