A tier-2 help desk technician is resolving a network connectivity issue on a desktop computer following a motherboard replacement. The computer displays a valid link light but cannot access local network resources. The technician identified the problem and tested their theory by reviewing IP configuration logs, confirming that the new onboard network interface card (NIC) was assigned an Automatic Private IP Addressing (APIPA) address () because the network's DHCP server enforces MAC address filtering. Having confirmed the root cause of the issue, which of the following is the NEXT step the technician should take according to the CompTIA troubleshooting methodology?
- Establish a plan of action to update the MAC address reservation on the DHCP server and implement the solution.Cevap
- BReboot the desktop computer and ping internal network shares to verify that full connectivity has been restored.
- CDocument the new MAC address, root cause, and resolution details in the central ticketing system.
- DReconfigure the local DNS server to dynamically route APIPA address queries directly to the default gateway.
Cevap
Establish a plan of action to update the MAC address reservation on the DHCP server and implement the solution.
The CompTIA troubleshooting methodology follows a mandatory order: 1) Identify the problem, 2) Establish a theory of probable cause, 3) Test the theory to determine cause, 4) Establish a plan of action to resolve the problem and implement the solution, 5) Verify full system functionality and implement preventive measures, and 6) Document findings, actions, and outcomes. Because the technician has already confirmed the cause (Step 3), the required next step is to establish a plan of action to update the DHCP server MAC reservation and implement that solution (Step 4).
