Hi Kenny,
No not yet, my first attempt is on 3 July I will let you know the result :-)
But my friend he took an exam on 26 April, and failed, it's normal (he will
take again on 26May). He told me that there is fault injection (or
troubleshooting) for the first section, if you can fix for 2 faults will get
3 points, something like this. It has about 6 fault items.
He told that it is in below issue:
- IP/Subnet mask
- Speed/ Duplex
- Allow vlan on trunk
- VTP mode, vlan, native vlan
- Spanning tree
- Frame Relay, encapsulation, lmi-type
- Clock rate
As Scott said the best way to troubleshoot is pinging on directly connected
interface. Troubleshoot it step by step, link by link. If you finish it
within 1 hr, it will be the best chance, a lot of remaining time for
remaining questions.
Please note that this troubleshooting is in L2, it you can't fix it, you
will be in trouble :S
Cheers,
Akaradeth

Hi Akaradeth,
U went for ur first attempt? How was it? I asked a colleague of mine to do a
comparison between IEWB vs the-REAL lab, he said IEWB was tougher. Any
comments?
I've scheduled my 1st attempt on August in sydney.
Would like to look for someone to discuss more on the concepts & practical
as i prepare for the lab.
Thanks.
Cheers,
Kenny
