Difficulty: Easy
Correct Answer: IPCONFIG
Explanation:
Introduction / Context: DHCP environments assign IP parameters automatically, so technicians must inspect what the client actually received. Windows provides a built-in tool for this purpose.
Given Data / Assumptions:
Concept / Approach: The ipconfig command displays current adapter settings. With the /all flag, it shows lease info, DHCP server, DNS servers, and whether DHCP is enabled. It is the definitive first check for configuration on Windows.
Step-by-Step Solution:
1) Open Command Prompt.2) Run: ipconfig /all.3) Review IPv4 address, subnet mask, default gateway, DNS servers, DHCP server, and lease times.4) If incorrect or stale, use ipconfig /release and ipconfig /renew to refresh.Verification / Alternative check: After renew, run ipconfig /all again and compare. Optionally ping default gateway to verify reachability.
Why Other Options Are Wrong:
PING checks reachability only; it does not list configuration.TRACERT shows path to a destination, not local settings.ARP displays MAC-to-IP mappings cached locally, not full DHCP parameters.“None of the above” is wrong because IPCONFIG is correct.Common Pitfalls: Forgetting /all, misreading virtual adapters, and overlooking that VPNs or vSwitches may add multiple interfaces.
Final Answer: IPCONFIG.
