What is the ipconfig switch to flush DNS cache?

ipconfig /renew
ipconfig /all
ipconfig /flushdns
ipconfig /release

The correct answer is: ipconfig /flushdns

The /renew switch in ipconfig is used to renew the IP address, while the /all switch displays all configuration information for all connections. The /release switch releases the IP address for a specified adapter. These options are not related to flushing the DNS cache. Therefore, C is the correct answer as it specifically targets the DNS cache.
