Which of the following statements is true about the 80/20 rule (Choose two)?

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.
