CompTIA A+ 220-1102 Practice Question

To control and monitor access to the data center, a badge reader is an effective solution. It ensures that only authorized individuals with valid badges can enter the area. This method provides a log of who enters and exits, increasing accountability and traceability. While guards can serve as a deterrent and respond to unauthorized access, they are not as precise in recording entries. Video surveillance, while useful for monitoring, does not control entry into the space. Door locks alone do not monitor or log entry/exit activities, making them a less comprehensive solution.
