Which of the following is NOT a benefit of VLAN?

• Cost savings result from reduced need for expensive network upgrades and more efficient use of existing bandwidth and uplinks
• Groups that have sensitive data are separated from the rest of the network, decreasing the chances of confidential information breaches
