Correct answers: A, B, D
Explanation
To diagnose network connectivity issues on a Windows device, it is essential to start with basic checks such as testing connectivity using 'ping,' verifying the network adapter status, and examining IP address configuration using 'ipconfig.' These steps help isolate whether the issue is with the local device, the network configuration, or external factors. More advanced tools like 'netstat' or drastic measures like reinstalling the OS are not appropriate for initial diagnostics.
- A. Correct.
Using the 'ping' command in the Command Prompt is a quick way to test basic connectivity to an external IP address or domain, helping to identify if the issue is network-related.
- B. Correct.
Checking the network adapter status in the Control Panel can reveal if the adapter is disabled, disconnected, or experiencing hardware issues.
- C. Incorrect.
'Netstat' is useful for viewing active connections but does not directly help diagnose basic network connectivity issues in this scenario.
- D. Correct.
The 'ipconfig' command provides details about the IP address, subnet mask, and gateway configuration, which are essential for diagnosing connectivity issues.
- E. Incorrect.
Reinstalling the operating system is an extreme and unnecessary step for basic network connectivity troubleshooting.
