Difficulty: EasyWindows Client Networking Configuration

A user reports that their Windows 11 workstation cannot access internal network shares or the internet. The technician runs the command line tool to check the network interface state and notices the IPv4 address is 169.254.10.45. After confirming the local DHCP server is operational, which command should the technician execute in the Windows Command Prompt to obtain a new IP address assignment?

  1. ipconfig /renewAnswer
  2. B
    ipconfig /flushdns
  3. C
    ipconfig /all
  4. D
    ncpa.cpl /renew

Answer

The command ipconfig /renew re-initiates the DHCP negotiation process to obtain a valid IP address from the DHCP server.
The ipconfig /renew command causes the network adapter to send a request to the DHCP server for a new IPv4 configuration, resolving the self-assigned APIPA address once DHCP communication succeeds.

Step-by-Step Solution

1
Identify the current networking state.
The address 169.254.10.45 indicates Automatic Private IP Addressing (APIPA), assigned when a client cannot contact a DHCP server.
Recognizing APIPA confirms that the client workstation currently lacks a valid DHCP lease.
2
Select the appropriate CLI command switch to request an address.
Running ipconfig /renew commands the client to broadcast a DHCPDISCOVER/DHCPREQUEST packet sequence to retrieve new configuration parameters.
Since the DHCP server is online, renewing the lease resolves the APIPA assignment and restores network connectivity.
