Show answer and explanation
Correct answers: A, C, D
Explanation
To verify IP parameters for different operating systems, the correct tools must be used. 'ipconfig' is the standard command for Windows, the Network Preferences GUI is commonly used for Mac OS, and 'ip addr' is the modern command for Linux. These tools provide detailed information about the IP configuration, such as IP address, subnet mask, and default gateway. Using incorrect or deprecated commands, such as 'ifconfig' on Mac OS, or unrelated commands, such as 'ping', will not achieve the desired result.
- A. Correct.
The 'ipconfig' command is the appropriate tool to verify IP parameters in Windows. It provides details like IP address, subnet mask, and default gateway.
- B. Incorrect.
The 'ifconfig' command was historically used on Mac OS, but it has been deprecated and replaced by other tools like 'ip' or the GUI options in macOS versions. This makes it an incorrect choice.
- C. Correct.
The Network Preferences GUI is a valid method to verify IP configurations on Mac OS, as it displays essential IP parameters such as the IP address and subnet mask.
- D. Correct.
The 'ip addr' command is the correct modern command for verifying IP parameters on Linux systems. It provides detailed network interface information.
- E. Incorrect.
While the 'ping' command can help test connectivity, it does not display IP parameters. Therefore, it is not suitable for verifying IP configuration.
