Comprehensive and Detailed Explanation: UsingPre-Shared Key (PSK)authentication means thatall users share the same Wi-Fi password, making it difficult toidentify individual userswhen security incidents occur. Migrating toWPA2-Enterprise(orWPA3-Enterprise) replacesPSK authenticationwithindividual user credentialsusing802.1X authentication and a RADIUS server. This allows the organization to: * Track and log specific user activity * Enforce per-user authentication policies * Improve network security Breakdown of Options: * A. Restrict users to the 5GHz frequency- Improvesperformancebut doesnot enhance user tracking or security. * B. Upgrade to a mesh network- Amesh network improves coverage,not security tracking. * C. Migrate from PSK to Enterprise-#Correct answer.WPA2-Enterprise or WPA3-Enterprise uses individual user authentication,allowing per-user tracking. * D. Implement WPA2 encryption-WPA2 is already widely used; itdoes not resolve the tracking issue.
