Which of the following statements is true about the 80/20 rule (Select all that apply)?
A.
20 percent of the traffic on a network segment should be local
B.
no more than 20 percent of the network traffic should be able to move across a backbone.
C.
no more than 80 percent of the network traffic should be able to move across a backbone.
D.
80 percent of the traffic on a network segment should be local
Explanation:
The 80/20 rule in network design originated from the idea that most of the traffic should
remain local to the LAN, since bandwidth is plentiful compared to WAN links, and a great
deal of broadcast traffic that is evident at the LAN is not passed over the backbone.
Note: With the availability of inexpensive bandwidth and centralized data centers, this rule
appears to have become obsolete. In fact, most networks have taken on the 20/80 rules, as
opposed to the legacy 80/20 rule.
