SDWOTS: SD-WAN Operations Troubleshooting and Best Practices 20.x


Course Overview:


This five-day course covers the new deployment,
options and features of version 20.x Cisco Software-
Defined WAN (SD-WAN). SD-WAN is an overlay
architecture that overcomes the biggest drawbacks of
traditional WAN. Students will learn how to design,
configure and operate a Cisco SD-WAN utilizing any
transport (MPLS, Broadband, LTE, VSAT etc.).
Candidates will discuss and build an SD-WAN
environment starting from Day 0 provisioning and will
also be able to provide troubleshooting, management,
policy control and application visibility across the
enterprise network. This hands-on Course covers the
Cisco SD-WAN product and contains extensive labs to
reinforce the knowledge learned.
