Course Code: TO 130
Course Abstract: This course is in development

Participants of this accelerated course are provided knowledge and skills to build large multiprotocol internetworks and how to manage them.  In addition, participants will learn to install and troubleshoot IS-IS, OSPF, and BGP.

The Building Scalable Cisco Internetworks (BSCI 642-901) is a qualifying exam for the Cisco Certified Network Professional CCNP®, Cisco Certified Design Professional CCDP®, and Cisco Certified Internetwork Professional CCIP™ certifications. The BSCI 642-901 exam will certify that the successful candidate has important knowledge and skills necessary to use advanced IP addressing and routing in implementing scalability for Cisco ISR routers connected to LANs and WANs. The exam covers topics on Advanced IP Addressing, Routing Principles, Multicast Routing, IPv6, Manipulating Routing Updates, Configuring basic BGP, Configuring EIGRP, OSPF, and IS-IS.

The CCIP (Cisco Certified Internetwork Professional) provides individuals working in service provider organizations with competencies in infrastructure IP networking solutions. CCIP professionals have detailed understanding of networking technologies in the service provider arena including IP routing, IP QoS, BGP, and MPLS.  The 642-901 exam is one of the four core exams required for the Cisco CCIP.

Examination
Within the three domains, Cisco will ask advanced questions on packet switching, trunking, and other complex switching technologies. As with most Cisco exams, the BCMSN is considered to be very challenging. Participants should expect to spend many hours studying for this exam both in lab and in text.  The exam normally lasts 75 minutes.  However, you will have 90 minutes to complete the exam.

Criteria for Certification
Cisco does not publish the pass score for this exam; however rumors say that the normal passing score is 849 out of 1000. The exam contains somewhere between 60 and 70 questions that include multiple choice, drag and drop, and simulation style questions in varying numbers.
