220-802 Question #147: Real Exam Question with Answer & Explanation
The correct answer is B: ipconfig /renew. The ipconfig /renew command sends a DHCP request to obtain a new IP address lease for the network adapter.
Question
A technician is trying to request a new IP address to a customer's computer through the command prompt. Which of the following commands should the technician use?
Options
- Aipconfig /flushdns
- Bipconfig /renew
- Cipconfig /all
- Dipconfig /release
Explanation
The ipconfig /renew command sends a DHCP request to obtain a new IP address lease for the network adapter.
Common mistakes.
- A. ipconfig /flushdns clears the local DNS resolver cache, which has no effect on the IP address assignment.
- C. ipconfig /all displays detailed network configuration information including MAC addresses and DNS servers but does not request a new IP address.
- D. ipconfig /release relinquishes the current DHCP-assigned IP address lease, leaving the adapter without an IP - it does not obtain a new one.
