Implementing and Operating Cisco Collaboration Core Technologies Hybrid and Cloud [CLCOR-HC]

OVERVIEW

This training is designed to give you a working knowledge of hybrid and cloud Cisco collaboration core technologies. After completing this training, you will have a basic understanding of the Cisco collaboration solutions architecture.

The Implementing and Operating Cisco Collaboration Core Technologies Hybrid and Cloud (CLCOR-HC) training is the second half of the CLCOR training. This training program is designed to give you a working knowledge of hybrid and cloud Cisco collaboration core technologies. After completing this training, you will have a basic understanding of the Cisco collaboration solutions architecture. You will have proven competence in deploying cloud and hybrid services, cloud and hybrid calling, as well as Quality of Service (QoS).

This training, along with the Implementing and Operating Cisco Collaboration Core Technologies On-Premises (CLCOR-OP) training, prepares you for the 350-801 CLCOR v2.0 exam. If passed, you earn the Cisco Certified Specialist – Collaboration Core certification and satisfy the core exam requirements for the Cisco Certified Network Professional (CCNP) Collaboration and Cisco Certified Internetwork Expert (CCIE) Collaboration certifications. This training also earns you 38 Continuing Education (CE) credits toward recertification.

OBJECTIVES

After this course participants should be able to:

• Introduce network engineers to the fundamental concepts and deployment models of Cisco collaboration architecture for building high-availability environments 
• Understand how to implement layered security across physical, network, and application components of Cisco Collaboration systems 
• Gain practical skills and strategic insight to ensure collaboration solutions function seamlessly by understanding the foundational infrastructure, signaling, and media transport protocols 
• Examine the basic structure of Webex 
• Apply various methods to add users to the Webex environment  
• Examine the Webex collaboration features 
• Examine the functions of Cloud Connected UC and migrations to Webex from on-premises 
• Explain Jabber functions and capabilities on Cisco Unified Communications Manager and how users can be migrated to the Webex app 
• Identify the Webex Calling provisioning options for adding user endpoints 
• Understand the foundational concepts of Webex APIs, including their types, authentication, capabilities, and real-time communication mechanisms 
• Identify the available options to bring PSTN calling capabilities into the Webex calling solution, identify the devices, and their configuration options, that provide this service 
• Describe the different deployment options when using local gateways in a premises-based PSTN Webex Calling solution 
• Explore the dial plan components of Webex Calling 
• Configure Cisco Unified Border Element and local gateway settings on a Cisco Router to support Webex Calling using a premises-based PSTN deployment 
• Explain how an administrator can configure calling features from the Webex Control Hub that will affect the organization 
• Describe how converged IP networks transport voice, video, and data over shared infrastructure and how bandwidth availability, delay components, jitter, and packet loss interact with QoS mechanisms to influence service quality and application performance 
• Explain how end-to-end QoS converts business requirements into predictable forwarding behavior under congestion across a multi-domain network 
• Implement consistent classification and marking policies to protect voice and video quality and resolve quality issues in a production network 
• Define QoS trust boundaries, understand Cisco Catalyst 9000 QoS design models, configure QoS marking and table maps, and leverage internal DSCP values for precise QoS actions
