Cisco CLCEI 300-820 study guide
Cisco CLCEI 300-820 · Work through your exam, one topic at a time.
The Cisco 300-820 CLCEI exam, listed by Cisco as Implementing Cisco Collaboration Hybrid and Cloud Technologies, is a concentration-style exam aimed at collaboration engineers who design, deploy, and operate hybrid environments that connect on-premises Cisco collaboration infrastructure with Webex cloud services. It suits administrators and engineers already comfortable with Unified Communications Manager, Expressway edge deployments, and Webex administration, who now need to prove they can bridge the two worlds securely. The Cisco CLCEI 300-820 study guide has 5 sections and about 1,968 words.
01Hybrid and Cloud Collaboration Architecture and Deployment Models
This domain tests whether you can look at a customer scenario and choose the right Cisco collaboration deployment, then name the hybrid service and connector that makes it work. Expect questions that contrast on-premises, cloud, and hybrid, and that ask which component sits where.
410 words, about 2 min02Webex Control Hub Administration and Licensing
This domain tests operational Control Hub skills: creating and syncing users, assigning the correct entitlements, delegating administration, and reading the analytics that prove a deployment works. Questions are usually scenario-based and hinge on which license or role actually delivers the feature.
380 words, about 2 min03Hybrid Calendar and Directory Integration (Microsoft Exchange, Active Directory)
This domain tests the two connectors that face the customer's identity and mail systems: Hybrid Calendar Service against Exchange, and Directory Connector against Active Directory. You must know the service accounts, permissions, protocols, and ordering that make each sync succeed.
382 words, about 2 min04Cisco Unified Communications Manager Cloud and Hybrid Call/Message Routing
This domain tests how calls and messages move between on-premises UCM, Cisco-hosted UCM Cloud, and Webex. You need to distinguish the platforms, know which connector carries call signalling, and be able to trace a dialled digit string end to end.
399 words, about 2 min05Edge, Expressway, and Secure Firewall Traversal for Hybrid Services
This domain tests the Expressway pair and the firewall design that lets external endpoints reach internal call control without exposing UCM. Expect questions on which port, DNS record, or certificate breaks a registration.
