CCIP 642-691 BGP+MPLS Real Exam Questions

The BGP+MPLS exam is the quickest way for currently certified Cisco Certified Internetwork Professionals to obtain recertification. The exam tests skills and knowledge pertaining to the Configuring BGP on Cisco Routers (BGP) and Implementing Cisco MPLS (MPLS) courses. BGP+MPLS may be taken to recertify your CCIP certification. It may also be taken in place of the BGP and MPLS exams required for the CCIP certification.
