A network operator is managing a network that has grown to include over 500 devices in a single VLAN. Users are reporting that network performance is slow, especially during peak hours. The operator notes a high level of broadcast traffic, such as ARP requests and service discovery protocols.
Why is this design a problem for network performance? (Select all that apply.)
A. Each broadcast frame must be processed by the CPU of every device in the broadcast domain.
B. Switches are unable to forward broadcast traffic, causing applications to fail.
C. A single large broadcast domain increases the number of collisions on the network.
D. Broadcast frames consume available bandwidth that could be used for unicast traffic.
E. Routers will automatically block all broadcast traffic, isolating the segment.
