Subject: CCIE written test questions [7:2497]
Hello all,
I have three questions that I cannot seem to find the answer to. ANy of you
learned people out there would be very much appreciated if you could give me
your best shot at these. I have my written tommorow and these questions are
stuck in my craw;
What is Fast Link Pulse?
http://www.cisco.com/warp/public/473/46.html
one of four documents that came up when searching CCO.
Auto negotiation for 10/100 ports - technical details
What is meant by TCP "Slow Start"?
http://www.cisco.com/warp/public/759/ipj_3-3/ipj_3-3_futureTCP.html
one of 150 documents returned when searching CCO
"part of the recovery process when acks are not received for packets sent.
. In this mode the sender immediately retransmits the lost packet and then
halves its sending rate, continuing to send additional data as permitted by
the current TCP sending window. "
probably a bit more complex.
What is the result of sending a loop up signal to the CSU/DSU?
CL: CSU goes into a loop state - i.e. depending upon who is doing the
looping, data received by the CSU is sent back to the originator, rather
than passed on to the network. One of the telco ( and router side )
troubleshooting techniques used to determine where carrier network problems
( if any ) may exist. Can also indicate if the CSU itself is bad.
There are probably other things that happen as well.
HTH
Best wishes on your exam.
I eagerly await any input.
Thanks,
Scott
