Hello group, The test outline for BCMSN 640-504 indicates that the exam includes DDR and Cisco TAC/CCO. I've been studying from the Coriolis Exam Prep, and there's no mention of Dial On Demand Routing or Cisco TAC/CCO. http://www.cisco.com/warp/public/10/wwtraining/certprog/testing/pdf/bcmsn.pdf Can somebody confirm that these topic are covered on 640-504? Thanks. _________________________________ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
