An enterprise has recently expanded its operations, and employees are experiencing slow network speeds. The IT manager suspects the issue might be due to the current throughput not meeting the increased demand created by additional users and upgraded applications. What would be an effective method to confirm if throughput capacity is indeed the root cause of the slow network speeds?
Inspect all networking devices for hardware faults.
Upgrade the firmware on all network routers.
Perform network bandwidth analysis.
Replace all existing Ethernet cables with higher category ones.
Increase the number of access points in the network.
