The industry recognizes that the 80/20 rule is no longer a legitimate
rule of thumb. It is not really even 20/80 these days. In fact, in
Kennedy Clark's "LAN Switching" book on p. 605 he states that on most
modern networks local traffic is *less than* 5%.
So if you want to turn that into a rule of thumb, I guess you'd say it
is 5/95.
I don't know what the "correct" answer on the CCNA exam is though.
The real world answer is more like 5/95.

| In the real world no, but for the CCNA yes. When you begin working towards
your CCNP, it depends on how the question is worded. As the new standard is
now 20/80. Even that might not be the case in a production network as
Bernie points out.

| Go with the Cisco rule. There are a few places where Cisco disagrees with
industry standards, but it is a Cisco cert, so just go with what Cisco says.

But that is exactly this guy's problem. Cisco states different
"rules" in different texts. So which one should this person go by? I
already provided the reference in a Cisco book (CCIE library) for the
new 5/95 rule of thumb. Is that or is that not a Cisco "rule"? It
just so happens to be in a fairly authoritative book on the subject of
Cisco LAN switching.

And then you can forget about it as it's no longer pertinent to the real
world.

Don't these tests still ask about (10 year dead) classful addressing
too?
