Official Training Course
Follow up the topic introduction with a comprehensive course administered by Cisco. This training comes in two delivery options, either a physical classroom with hands-on labs or e-learning. Both run for 5 days, with a specific audience targeted for collaboration administrators and collaboration engineers.
The course outline is very exhaustive and well-thought-out to provide you with the most relevant knowledge needed for your upcoming exam as well as your job role. Its main objective is to provide quality learning through blow-by-blow discussion and lab practices. Completing this program shapes your skills in Cisco Unified CM, together with Cisco Expressway, their configuration, and additional features. Subsequently, lectures acquaint you with troubleshooting of collaboration solutions and security of B2B communication. Also, using Cisco Collaboration, you gain proficiency in B2B calls.
Another key part of the course is Cisco’s Mobile and Remote Access (MRA). At this point, there will be an all-inclusive explanation of important skills, specifically in designing, troubleshooting, integrating, and securing MRA features. Some of the primary aspects that are deliberated include Cisco Instant Messaging and Presence and Cisco Unity Connection. Concluding the discussion are Cisco Webex Hybrid Services.
With the combination of lectures and labs, you get the upper hand with your test preparation. It readily highlights your knowledge of leveraging collaborative technologies for the accessibility of work supports such as content, voice, video, and remote workloads. And considering the weight and extensiveness of the course, there are certain prerequisites that needed to be cleared beforehand. First of all, it’s imperative to have a solid background in networking technologies, predominantly in voice and video. Unerring comprehension of basic Cisco collaboration solutions and Cisco Unified Communications Manager call control fundamentals is also a must. Lastly, you should already be familiar with vital signaling protocols like XMPP and SIP. If you think your contextual grasp is not enough, it’s advisable that you take the associated courses. These are “Understanding Cisco Collaboration Foundations” and “Implementing and Operating Cisco Collaboration Core Technologies”.
