As someone who has never attended a CCIE Training Class nor buddied up with a fellow CCIE Candidate, I had a feeling I was missing something – that extra bit of help or guidance to see an issue through another per of eyes. Following some research I chose the CCIE SP Lab Mentoring Kit from IPExpert. Ref: https://www.ipexpert.com/index.cfm/product/sku/IPX0533
What stood out for me was “The instructor will explain how the portion being discussed relates to all of the other tasks involved in a particular lab.” This is incredibly important for the SP Exam – the inter-dependencies between tasks which I can attest to – Even Nugroho references this fact in his blog entry here -> http://brokenpipes.blogspot.com/2008/03/how-to-become-ccie-v2.html
Finally, I would like to add that Mike Down in Ipexpert was very helpful regrding costs on the product and I would recommend getting in touch with him regarding IPexpert Purchases. Thanks Mike.
