Update this graphic -> https://github.com/RedHatTraining/DO457/blob/main/guides/en-US/images/skeleton/snippets/en-US/assets/zzz-classroom-architecture.svg

Remove servera, serverb, serverc, and serverd and add the following:

• utility
• controller
• hub
• git
• arista1
• arista2
• ios1
• ios2
• junos1
• junos2

The following are network devices and should use a different icon than servers:

• arista1
• arista2
• ios1
• ios2
• junos1
• junos2

This icon seems appropriate -> https://vecta.io/symbols/240/cisco-network-topology-icons-3015/126/layer-3-switch
