A network administrator is troubleshooting a network in a large office where employees are complaining about slow internet speeds and intermittent disconnections. The network uses Cat$6$ cabling, and the administrator notices that the cables run parallel and very close to fluorescent lighting fixtures throughout the office.

What should the administrator investigate as a potential cause of the network issues?

###answer###

The fluorescent lighting is causing electromagnetic interference.

The network switches are outdated.

The internet service provider is throttling the connection.

The cables are not rated for the speed of the network.
