CCNP Collaboration case studies
CCNP Collaboration · Put your knowledge to work in context.
CCNP Collaboration (often shortened to CCNP Collab) is Cisco's professional-level certification for engineers who design, deploy, configure, and troubleshoot enterprise collaboration environments. It sits above the associate-level CCNA Collaboration track and is aimed at voice and collaboration engineers, unified communications administrators, and design or support staff who work daily with call control platforms, collaboration endpoints, gateways, and edge services rather than with routing and switching alone. The CCNP Collaboration case studies are 5 cases and about 4,638 words.
