During the deployment of a new network segment, technicians report that connectivity to network resources is intermittent. Some workstations are able to access network drives sporadically while others seem to have no issues. Physical connections, DHCP configurations, and user permissions have been verified and are correct. Given these symptoms, what should the network administrator investigate next?
Verify if a switching loop is present by checking the spanning-tree configuration.
Upgrade firmware on all network devices within the segment to ensure compatibility and rule out software bugs.
Replace all network cables within the new segment as they may be the cause of the intermittent connectivity.
Check for malware on the workstations as it could be disrupting network connectivity.
