No the CCDA book states that nowadays the original rule is reversed due to
central server locations etc etc. It is merely stating that when designing
a network you have to take the considerations mainly of political business
issues under concern. It is less traffic intensive to have your servers
local to your main users but in most cases all the servers are located in a
central location and with a client server model most of your traffic will
therfore leave your subnet.

Here it is, the answer you just *knew* was coming...ready?...
IT DEPENDS! ;-)
It depends on which book you're reading and which test you're studying for.
The original 80/20 rule stated that your network should be designed so that
80% of your traffic remains on the local LAN, and 20% of your traffic will
cross your WAN.
Well, when I sat down and began reading the CCDA study guide, the authors
reversed that rule, and said that only 20% of traffic will remain on the
local LAN, and 80% will traverse the WAN. At first I thought that they were
horribly confused (a la the whole poison reverse thing - don't get me
started!), but then they explained that with a network which is connected to
and relies heavily on the Internet for business reasons, this rule is
reversed.
So it basically boils down to traffic patterns - LAN traffic vs. WAN
traffic, and what your network has to be capable of handling.
Hope this helps.
Sincerely,
