Cisco DESGN 2.1: Voice and Video Technology Requirements

This course is included in our On-demand training solution.


To create a proper integrated network design, you need to know about the many considerations that affect voice traffic. This course focuses on the types of delay, bandwidth restrictions, and Quality of Service (QoS) issues that affect voice communications. It discusses the importance of coding, which affects bandwidth consumption, voice and video quality, and introduces mechanisms that impact voice and video quality.
To design a network to transport voice and video, you need to understand and consider delay, packet loss, jitter, and the impact that QoS can have on maintaining voice quality.

Target Audience

Anyone wishing to obtain the Cisco Certified Network Associate (CCDA) certification that validates the knowledge and skills required to successfully design Cisco converged networks. Candidates who have completed the 640-816, 640-822, or 640-802 Cisco Certified Cisco Network Associate certification exam.


Expected Duration

120 min.
