The Composite exam (642-891) is the quickest way for currently certified Cisco Certified Network Professionals (CCNP?) and Cisco Certified Design Professionals (CCDP?) to obtain recertification. The exam tests skills and knowledge pertaining to the Building Scalable Cisco Internetworks (BSCI) and Building Cisco Managed Switched Networks (BCMSN) courses. Composite may be taken to recertify CCNP and CCDP certifications; it may also be taken in place of the BSCI and BCMSN exams required for CCNP and CCDP certifications. Candidates must successfully pass both routing and switching subsections of the ComposITe exam to successfully pass the exam.

The following information provides general guidelines for the content likely to be included on the Cisco ComposITe Exam. However, other related topics may also appear on any specific delivery of the exam.
