Exam Description
The Building Scalable Cisco Internetworks exam is a
qualifying exam for the CCNP®, CCDP®, and CCIP™ certifications. The BSCI exam
(642-801) tests materials covered under the new Building Scalable Cisco
Internetworks (BSCI) course. The 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 routers connected to LANs and
WANs. The exam covers topics on Advanced IP Addressing, Routing Principles,
Configuring the EIGRP, Configuring the Open Shortest Path First Protocol,
Configuring IS-IS, Manipulating Routing Updates, and configuring basic BGP.
Exam Topics
The following information provides general guidelines for
the content likely to be included on this exam. However, other related topics
may also appear on any specific delivery of the exam.
