CCNP-WS courses are gaining in popularity as companies recognize the need for qualified, certified WAN professionals. This Coursebook is an excellent resource that supplements instructor-led training classes and offers an alternative self-paced study option to those not attending the recommended courses. The book contains updated course material for the four courses recommended for CCNP-WS preparation: 640-419 Multiband Switch and Service Configuration (MSSC); 640-425 BPX Switch and Service Configuration (BSSC); 640-411 MGX ATM Concentrator Configuration (MACC); and 640-459 Cisco WAN Manager Installation and Operation (CWMIO). It contains five parts, with Parts II through V devoted to the four courses. Review questions and answers appear at the end of each major part. An appendix lists commands for the MSSC, BSSC, MACC, and CWMIO.
