Hi,
I had to take a look at rfc 894 (ethernet) and rfc 1042 (ieee802)
from rfc 1042:

It is possible to use the Ethernet link level protocol [12] on the
same physical cable with the IEEE 802.3 link level protocol. A
computer interfaced to a physical cable used in this way could

A device can best be described by its chief function. You can use a
PIX as a router, just allow everything through. In fact you can use a
router as a firewall, be selective with access lists. Terminology is
flexible as long as you're pragmatic about function.

Close. IP routing protocols *may* use layer 4 sockets for data. But for

Neil is correct. Fast ethernet can be used in a shared medium environment
(repeaters, fast hubs) that don't support full-duplex.

To be fair, the CCNA is an entry level exam. If you are experienced, it is
a piece of cake. Cisco has designed the exam for Level 1 support
opportunities. Learn well and good luck on your journey.

I think there is some confusion between ISL and IEEE 802.1q.
Remember Cisco ISL VLAN ID field is 10 bits i.e. 2^10 or 1024 possible
(0-1023)
Just *think* about how many bits in an IEEE 802.1q frame it takes to make
4096 VLANs.

I don't think it's an attempt to reduce the number of candidates vs. a
recognized stream for added revenue. As a cynic, I think it has very
little to do with rising costs.
