100-140 Question 213
Single answerYou are troubleshooting a connectivity issue on a Windows machine where the user reports they cannot access any websites. After running the 'ipconfig' command, you notice the IP address is listed as '169.254.x.x'. What would be the most appropriate next step to attempt resolving this issue?
- A
Release and renew the IP address using 'ipconfig /release' and 'ipconfig /renew'
- B
Restart the computer to apply a new IP address automatically
- C
Manually assign a static IP address to the machine
- D
Check if the DHCP server is functioning and accessible
Show answer and explanation
Correct answer: A
Explanation
When a machine assigns itself an APIPA (169.254.x.x) address, it typically indicates that it was unable to obtain an IP address from the DHCP server. The 'ipconfig /release' and 'ipconfig /renew' commands should be used first to attempt to resolve this issue by refreshing the IP configuration. If this does not work, further steps like checking the DHCP server or assigning a static IP may be required.
- A. Correct.
'ipconfig /release' and 'ipconfig /renew' are appropriate commands to attempt first, as they can refresh the IP configuration and potentially resolve the issue caused by the system assigning an APIPA (169.254.x.x) address.
- B. Incorrect.
Restarting the computer may or may not resolve the issue, but it is not the most immediate or targeted solution to an IP address configuration issue.
- C. Incorrect.
Manually assigning a static IP address is not ideal in this situation unless it is confirmed that the DHCP server is unavailable or not functioning properly.
- D. Incorrect.
Checking the DHCP server is a valid troubleshooting step, but it should be performed after attempting to release and renew the IP address to rule out simpler issues.
