What is the primary purpose of a VLAN?
Ans: To create a broadcast domain; enable segmentation or isolation of broadcast traffic
Qiz Unassigned Cisco switch ports remain in which VLAN?
Ans: VLAN 1
Qiz Do VLANs prevent broadcast storms?
Ans: No, they minimize the size and effect of the broadcast storm on neighbor switches and hosts
Qiz What are four advantages to using VLANs?
Ans: 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. Bandwidth efficiency is accomplished through segmenting traffic into smaller broadcast domains
4. Easier add/move/delete administration of endpoints on a network and scalability for larger enterprise
