GNS3 Certified Associate Official Course (GNS3A) – David Bombal

This is the official GNS3 Certified Associate course. This course covers the topics you need to know to pass the GNS3CA Exam.The GNS3 Certified Associate (GNS3A) program is a multi-vendor, next generation network engineer certification that focuses on the core skills that network engineers need today for the new era of rapidly changing, programmable, automated and intelligent networks.In today’s rapidly changing networking environment where billions of IoT devices are being added to the Internet every year, it is no longer enough for network engineers to simply configure network devices manually via a Command Line Interface (CLI). Network engineer skill-sets need to diversify to include network programmability and automation skills such as Ansible and Python, programmable APIs, Open Networking technologies, virtualization, Linux and support of multi-vendor environments.The GNS3A program will prepare you to have the knowledge and training to:Install and build virtual networks using GNS3 with knowledge of multiple vendors and protocolsExplain and describe GNS3 core functions and architectureIdentify and troubleshoot GNS3 installation and configuration issuesProgram networks using Python network automation scriptsImplement OpenFlow based SDN networks within GNS3 topologiesImplement Docker based appliances within GNS3 topologiesDescribe DevOps terms such as Data Formats, APIs, REST, NETCONF and
