Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) Exam Format
Everything the official exam blueprint specifies: question count, time limit, scoring and the weight each domain carries. The CLCOR (350-801) exam validates the core skills required to implement and operate Cisco Collaboration technologies. It covers a broad spectrum of unified communications, ranging from the underlying network infrastructure and QoS to complex call control mechanisms and media resource management. Candidates must demonstrate proficiency in managing Cisco IOS XE gateways, configuring SIP-based communications, and integrating collaboration applications like Webex. This certification ensures that engineers can design, deploy, and troubleshoot robust communication ecosystems that support high-quality voice, video, and presence services within the enterprise.
