Priscilla, you forgot a couple of skills required.
- the ability to provide a complete design, with detailed costings, from a
one-line requirements specification that is so high-level it needs oxygen tanks.
- the ability to do this within an hour.
- the ability to justify your answer six months later with a straight face.
- the ability to separate out the actual business requirements from the
technical buzzwords that the requirements writer added into the spec because
they thought they sounded good.
- the ability to re-add the technical buzzwords into the design presented to the
business owners so they think it looks good.
- the ability to politely explain to management why what they just said is utter
rot, without offending them.
- the ability to recognise the difference between your own life and a Dilbert
cartoon (this is one of the harder skills to master).

A designer should be logical, analytical, and able to spend lots of quiet
time thinking before implementing. (Some people aren't good at this! &;-)
He or she should be aware of the technical details of many different
solutions and be able to select the right solutions after figuring out what
problems need solving.
Skills include analyzing business and technical requirements,
characterizing the performance of the existing network using network
management and protocol analysis tools, figuring out typical traffic flows
and loads (not easy on most networks!), developing a topological view of an
internetwork, designing addressing solutions that conserve addresses and
support summarization, selecting products for implementation, designing
wiring schemes, testing the implementation, etc. (See the Table of Contents
of my book for my opinion of what a designer should be able to do. &;-)

Network architect and network engineer are often other names for network
designer. These are often the most senior-level people at companies. In
some companies the network architects have formal PhD-level training in
computer science, mathematics, queuing theory etc. This isn't always the
case, of course, but at large ISPs and many universities it's true.
Usually a network architect has had many years experience in operations and
is well aware of configuration commands that will make the designs work.

It is not true. You need to know the commands for the lab part of the test.

To become a CCDP you have to take CCDA, CCNA, Routing exam, Switching exam,
Remote Access exam, and CID. To become CCIE you have to take a written test
and a 2-day excruciatingly difficult hands-on lab test.
The CCIE exams are managed by a different department at Cisco than the
Career Certifications. Despite some Cisco marketing material, there really
isn't a stair-step relationship between Cisco Career Certifications and the
CCIE program. Most people prefer to take the other exams first to get some
practice, but it's not required. If you're a hot shot, it makes sense to go
for the CCIE level first, since that's the most respected.

It could help. Most of the network design tools support drawing packages
that are pretty simple though. Figuring out what to put on the drawing is
the hard part!

I think most CCIEs are R/S. My guess is the number is more like 80 %. Only
a guess though.
So that's my opinion anyway! I think it would be great if more people took
the design tests and if more employers expected the design certifications.
The idea that surfaces every so often that these tests are easier or less
technical is based on false assumptions. Which is easier, to operate a car
or to design a car?
