Overview

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 (GNS3CA) 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 GNS3CA 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 othersProgram networks using Ansible network automation scriptsInstall and configure Linux based virtual machines and core Linux functionsInstall, configure and troubleshoot hypervisors such as VMware Workstation, ESXi, QEMU and VirtualBoxTroubleshoot basic network issuesExam topics:Core GNS3 SkillsExplain GNS3 architecture:GNS3 GUIGNS3 VMLocal versus remote VMsSchema (GUI / Web / Controller / Compute / Emulators)Explain, configure and troubleshoot GNS3 Hypervisor optionsVMware Workstation ProVMware Workstation PlayerVmware FusionVirtualBoxESXiQEMUDescribe GNS3 cloud solutions:Packet netExplain and contrast GNS3 device supportSwitchesRoutersFirewallsServersHostsExplain, configure and troubleshoot device types:Built-inHubSwitchCloud optionsNetwork VendorsDynamips IOS routersCisco IOSv applianceCisco IOSvL2 applianceArista vEOS applianceJuniper SRXv applianceFRRouting applianceServer / PC appliancesUbuntu ApplianceNetwork Automation ApplianceNetworker's Toolkit ApplianceDNS applianceOther popular GNS3 appliancesTroubleshoot GNS3 installation issues (GUI and VM)Describe GNS3 best practicesGNS3 GUIGNS3 VMEmulation optionsVendor device emulation / simulation optionsDescribe and use GNS3 programmability optionsREST APIcURLPostmanPython scriptsBash scriptsPython:Describe Python terms including:ObjectsVariablesStringsIntegers and floatsBooleansOperatorsListsDictionariesTuplesLoopsConditionsFunctionsExplain and troubleshoot Python code snippets includingText manipulation (split / join / concatenation)Loops (for / while)If / else / elseif logicDescribe and verify the Python Telnet library for network device automationDescribe, verify and troubleshoot the use of Netmiko for network device automationDescribe, verify and troubleshoot the use of NAPALM for network device automationLinuxDescribe Linux distributions (Red Hat, CentOS, Fedora, Debian, Ubuntu, Mint)Describe Linux Text editors (vi, nano)Configure, verify and troubleshoot IPv6 addressing, default gateways and static routes (Ubuntu)Describe and verify Linux Directory structures (Ubuntu)Describe file copying, moving and deleting (Ubuntu)Describe and verify common Linux commands (ls, grep, more, cat, less) (Ubuntu)Describe and verify Linux Permissions (Ubuntu)Describe Linux Processes (Ubuntu)Configure and verify Linux software installation (Ubuntu)Configure and verify Linux DNS server (dnsmasq)Configure and verify Linux DNS server (dnsmasq)Configure and troubleshoot network devices such as Cumulus Linux, Arista, NX9000 and FRR using Linux commandSDNDescribe SDN terms and definitionsController functionsPlane separationNorthbound interface (APIs)Southbound interface (APIs)NFVDescribe and contrast SDN visionsOpen SDNSDN via OverlaysSDN via APIsAutomation based SDNDescribe SDN protocolsOpenFlowNETCONFVxLANYANGDescribe and contrast Data FormatsJSONXMLYAMLDescribe source control using GitDescribe APIsNetwork Device APIsREST APIsDescribe and contrast SDN controllers:Open source SDN controllers (OpenDaylight, ONOS, RYU)Vendor SDN controllers (NSX, ACI, APIC-EM)Describe and verify basic OpenFlow switch flows (OVS / Mininet)OpenFlow 1.0 and 1.3 onlyProactive vs Reactive flowsPipeline ProcessingMatch TypesMatch ActionsMessage typesOpenFlow PortsAutomation ToolsAnsibleInstall and configure Ansible for network automationDescribe and contrast agentless vs agent based automation toolsDescribe Ansible terms such as Idempotency, Ad Hoc changes, inventory files, plays, tasks and playbooksImplement and troubleshoot Ansible scripts for network device automationDescribe and contrast Salt, Puppet and ChefVirtualization technologiesDescribe and contrast hypervisorsVMware Workstation ProVMware Workstation PlayerVMWare FusionVirtualBoxQEMUESXiDescribe and contrast virtual image types (img, qcow2, iso, ova and vmdk)Explain virtualization concepts such as nested virtualization, host virtualization, network NIC virtualization, network device sizing and scaling.Install and configure GNS3 supported hypervisorsInstall and configure GNS3 with cloud based providers such as Packet net
