What commands would you use to globally create and name a VLAN? - ️️vlan # name name_of_vlan What are four advantages to using VLANs? - ️️1. Enable access to network services based on logical requirements 2. Network security is optimized with VLANs that enable managing and filtering sensitive traffic from other network traffic 3.
