Description |
|
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. |
