A desktop computer on an enterprise network is unable to access local intranet shares or remote internet sites. A technician runs the `ipconfig /all` utility on the client machine and obtains the following network configuration details:
- IPv4 Address:
- Subnet Mask:
- Default Gateway: [Blank]
- DNS Servers: [Blank]
Based on this output, which of the following statements correctly identify the cause of the problem and the appropriate troubleshooting steps? (Select TWO.)
- The host automatically assigned itself an Automatic Private IP Addressing (APIPA) address after failing to contact a DHCP server.Answer
- The technician should verify physical network connectivity and check whether the DHCP service or relay agent is operational.Answer
- CThe local DNS server configured this IP address assignment because host name resolution requests timed out.
- DAn unmanaged Layer 2 switch must be installed to route traffic between this workstation and external subnets.
Answer
The client computer self-assigned an APIPA address because it could not communicate with a DHCP server, and the technician should troubleshoot physical connectivity and verify the operation of the DHCP server or relay agent.
When a Windows computer is configured for dynamic IP addressing (DHCP) but does not receive a response from a DHCP server, the operating system self-assigns an APIPA address in the range to . Because APIPA does not configure a default gateway or DNS servers, external communication fails. Troubleshooting requires checking physical connection integrity and ensuring the DHCP service or relay agent is running and accessible.
