A desktop computer in a office environment is unable to access local network resources or the internet. Running `ipconfig /all` on the workstation displays an IPv4 address of . Upon physical inspection, the technician observes that the link light on the workstation's network interface card (NIC) is completely unlit. Which of the following initial troubleshooting steps should the technician perform to address this issue? (Select TWO.)
- Test or replace the Ethernet patch cable connected between the workstation and the wall jack.Cevap
- Verify that the corresponding switch port in the patch panel room is enabled and showing physical link activity.Cevap
- CReconfigure the local DNS server settings to lease dynamic IP addresses to client workstations.
- DManually set the workstation network adapter to operate on non-overlapping 2.4 GHz channel 6.
Cevap
The technician should test or replace the Ethernet patch cable and verify that the corresponding switch port is enabled and showing physical link activity.
The presence of an Automatic Private IP Addressing (APIPA) address () combined with an unlit NIC link light points directly to a Layer 1 (Physical layer) failure. Testing or replacing the Ethernet patch cable and verifying that the network switch port is active and enabled directly troubleshoot the physical link layer. Establishing a physical connection is required before the client can reach a DHCP server.
