Because a DHCP client receives its IP configuration dynamically, which Windows utility should you use to read and verify the current network configuration on that client?

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:

  • OS: Windows workstation.
  • DHCP assigns IP address, mask, gateway, and DNS.
  • Goal: read and verify the live configuration.


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.
