An organization has four departments that each need access to different resources that do not overlap. Which of the following should a technician configure in order to implement and assign an ACL?
Correct Answer: A
VLANs (Virtual Local Area Networks) segment network traffic by department, allowing ACLs (Access Control Lists) to be applied based on VLAN membership, improving security and resource isolation.
Breakdown of Options:
A). VLAN - Correct answer. VLANs enable logical network segmentation, allowing ACLs per department.
B). DHCP - Assigns IP addresses but does not control access.
C). VPN - Provides remote access, not segmentation within a network.
D). STP - Prevents switching loops, not related to ACL implementation.
