I don't have my DCB CD here. The only CCDA book I have in the office is the
Sybex Exam Notes by Devin Akin and Mr. Lammle.
On page 243 the list "Pilot Smaller in scale;" and a "Prototype Larger
than a pilot". They then go on in the next chapters to list the steps for
starting a Pilot and Prototype continuing with the Pilot=Small
Prototype=Large theme.
Todd would you like to comment?
Of course in the real world (I some times wonder if there is such a thing
anymore) does it really matter what the difference is, or if even if there
is one? This seems like one of those test questions that the original exam
objective; knowing that you don't have to build a large scale test
environment to prove your concept, gets turned around by someone into having
to define what Pilot and Prototype are. It just seems silly. But I still
do want to know the answer. Sick puppy I am.
Have a good new years everyone. See you next
year/decade/century/millennium.

Subject: RE: Prototype and Pilot
It sounds like I may have had it backwards in my message, then??
Bottom line: the terms are not used precisely in the real world. We need to
find out if the questioner just wants to know how to use the terms for the
DCN test, which is my guess, and then help him with the Cisco DCN viewpoint.
The Cisco Press DCN book just has this confusing thing to say on the topic:
"For larger configurations, a prototype is generally more feasible. For
smaller configurations, a pilot might be more practical. The decision will
probably be made on relative costs; the costs for prototyping a portion of
the network will be relatively small for a larger network. However, if the
network itself is small, then prototyping it could involve costs that are
relatively large compared to the total costs of the project, so
demonstrating basic functionality with a pilot might be more feasible."
Does anyone have any other more useful CCDA books that would answer this
question? My book has a whole chapter on testing a network design, but I
didn't address the objective of distinguishing a prototype and pilot, since
I can't (and I didn't know Cisco expected anyone to. &;-)
