Question 2

What are three benefits of implementing VLANs? (Choose three.)

A. higher level of network security can be reached by separating sensitive data traffic from other network traffic
B. more efficient use of bandwidth can be achieved allowing many physical groups to use the same network infrastructure
C. more efficient use of bandwidth can be achieved allowing many logical networks to use the same network infrastructure
