The 642-889 SPEDGE Implementing Cisco Service Provider Next-Generation Edge Network Services tests a candidate’s knowledge of service provider VPN solutions through enabling point of presence to provide Layer 2 and Layer 3 VPNs. This exam covers the Cisco IOS, IOS XE and IOS XR operating systems. Candidates can prepare for this exam by taking the Implementing Cisco Service Provider Next-Generation Edge Network Services (SPEDGE) course.
The 642-889 SPEDGE Implementing Cisco Service Provider Next-Generation Edge Network Services exam is associated with the CCNP® Service Provider certification. This 90-minute, 65−75 questions exam tests a candidate’s knowledge on the concepts and implementation of VPN solutions from the Service Providers perspective, including simple and complex layer 3 MPLS VPNs, CSC, 6VPE, and layer 2 VPNs such as AToM and VPLS. This exam covers the Cisco IOS, IOS-XE and IOS-XR operating systems. Candidates can prepare for this exam by taking the Implementing Cisco Service Provider Next Generation Edge Network Services (SPEDGE) course. The exam is closed book and no outside reference materials are allowed.
