hmmm, duplex issues.
Wrong IP addresses, incorrect network masks, Incorrect wild card masks.
Also, I have noticed that junior engineers have trouble coloring in the network diagrams in a manner that really adds value to the diagram without clutering it. So, if we had an excercise where we could color a diagram with virtual paint (crayons) then we could really show our skills off.
Yeah these are all really tricky and should be on the exam.
Hi Lora O
I do not know which of this would be covered by CCIE but here are some real ones.
maximium of routes in VRF - always fun when a node comes back again.
Running spanning tree with HSRP - guess the direction with two routers and two switches
Change the config register so it picks up on the on-board flash and ignores the boot statement.
CCIE voice - switch off ip routing for one way conversation.
Let the 3750 switch nullify the precedence and watch Video Conference break up.
Distribute bgp into rip and then rip into bgp with transparent metric
Run gre over isdn dialler but do not change the mtu
Switch off password encryption when using PPP CHAP but paste the user password into the configuration encrypted
Missing dialer pool
European one but only provide less than 15 channels on a ISDN-PRI and try outbound call.
E1 un-framed at one end and channelised the other.
Voice Router clock source and slips
Remove BGP as-override when AS is same at both end.
Miscode the remote AS number and wait for the message. Also duplicate bgp router id
Nat local devices before nating them onto the Internet. Fun with Cisco phones and XML servers.
delete tftp-server statements used to load Cisco phone and play tftp debug to guess which ones are missing.
Translation patterns on CME when Telco has special rules. Play find the rules when a call fails.
Anything involving default routes when they point in different directions.
Fatigue test - keep person awake for 24 hours before testing to test the clarity of mind.
Anything to do with using BGP to connect IS-IS AS
NTP master and sync
Violate the weight rule on a 7206
HWIC-1FE on the wrong IOS
Maybe using the aux port to provide PPP to access GUI and then change the modem type so the modcap statements no longer work.
Guessing the E3 problem when the Telco box has no text above them. The classical local remote alarm scenario
Show environment and broken power.
Good old old one time password and aaa new-model with no user. Always good for a laugh.
time acl and QOS
Anything to do with dns-servers on the router.
Perhaps instructing end-user to connect the correct cables.
I think they should be forced to roll out 100 Cisco telephones and then name the various cdp record types or explain OSPF network types.
Interesting I had never seen the CDP record types listed until I read Cisco Telepresence Fundimentals. I have not quite read it all I am still stuck in the chapter about paint.
I like Uraymo's idea. They could be given a network diagram from 1966 and using cdp guess what bits have changed.
I believe the troubleshooting section is great and hope it can be expanded. There should be an element of uncertainty in order to distinguish between the candidates who learned the technology and those who memorized the configuration. One question troubles me that I hesitate to ask in fear of being accused being paranoid. Are troubleshooting questions the same across all R&S exam locations? I got a sense that some people walk into the lab exam knowing what question they will receive. That could only be possible if someone who took the exam say in Beijing sends the information to a person taking the exam say in San Jose. (Beijing is 14 hours ahead of San Jose, so there is plenty of time to transfer the information after the exam). I am certain someone at Cisco looked at this possibility? Did they?
