About
CLCOR (Collaboration Core) is the mandatory first exam for CCNP Collaboration certification. Launched in September 2020, it validates expertise across voice and unified communications infrastructure, protocols, call control, quality-of-service, and collaboration application integration. To earn CCNP Collaboration, candidates must pass CLCOR (350-801) plus one concentration exam: CLICA (UC Applications, 300-810), CLACCM (Call Manager, 300-815), CLCEI (Cloud & Edge, 300-820), or CLAUTO (Collaboration Automation, 300-835). CLCOR targets collaboration engineers and voice architects managing on-premises or hybrid Cisco telephony, Webex, and unified communications platforms.
Domain context — Networking / Voice & Unified Communications
Voice and unified communications infrastructure spanning session initiation protocol (SIP), media transport, call control, and collaboration endpoints. Focus on voice quality, multisite deployments, gateway integration, and cloud-hybrid architectures.
