Explanation

Network troubleshooting often requires the use of multiple tools that address different aspects of the issue. ipconfig helps identify and verify the IP configuration, ping checks basic connectivity, tracert helps trace the path of network packets to identify bottlenecks, and nslookup ensures DNS resolution is functioning correctly. Disk cleanup, however, is not relevant to network troubleshooting.

  • A. Correct.

    ipconfig is used to view and manage the IP configuration of a device, which is crucial for verifying network settings.

  • B. Correct.

    ping is used to check connectivity to another device or server, helping diagnose network connectivity issues.

  • C. Correct.

    tracert is used to trace the path packets take to a destination, useful for identifying where network issues occur.

  • D. Incorrect.

    disk cleanup is unrelated to network troubleshooting as it is used to remove unnecessary files from a computer to free up disk space.

  • E. Correct.

    nslookup is used to test and troubleshoot DNS resolution, ensuring domain names resolve to the correct IP addresses.
