- A
ping 8.8.8.8
Why wrong: Incorrect. ping tests connectivity to a host, it does not release or renew IP addresses.
- B
ipconfig /release
Correct. ipconfig /release releases the current IP lease, and then ipconfig /renew obtains a new one from DHCP.
- C
nslookup google.com
Why wrong: Incorrect. nslookup queries DNS servers to resolve domain names, not IP address renewal.
- D
netstat -a
Why wrong: Incorrect. netstat displays active network connections and listening ports, not IP configuration.

220-1202 Windows Command-Line Tools Practice Question
This 220-1202 practice question tests your understanding of windows command-line tools. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A customer complains that their Windows 10 laptop frequently loses network connectivity. You suspect the IP address configuration is incorrect. Which command should you use to release the current IP address and request a new one from the DHCP server?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"which command"Why it matters: Tests specific CLI syntax. Recall the exact command and its required context — near-synonyms and partial matches are common distractors.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
ipconfig /release
Option B is correct because the `ipconfig /release` command sends a DHCPRELEASE message to the DHCP server, discarding the current IP address lease. This is followed by `ipconfig /renew` to request a new IP address from the DHCP server, which resolves connectivity issues caused by an incorrect or stale IP configuration.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse `ipconfig /release` with `ipconfig /flushdns` or think `ping` can reset network settings, but the question specifically requires a command that releases the current IP address, which only `ipconfig /release` does.
Detailed technical explanation
How to think about this question
The `ipconfig /release` command sends a DHCPRELEASE packet to the DHCP server, which sets the client's IP address to 0.0.0.0 and removes the lease. A subsequent `ipconfig /renew` broadcasts a DHCPDISCOVER message to obtain a new lease, which is essential when the DHCP server has assigned a conflicting or expired address. In real-world scenarios, this two-step process is often used after moving between different subnets (e.g., from office to home) to force the client to obtain a correct IP for the new network.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1202 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
