View Answer

Answer: A

Explanation:

Correct Answer. A. ifconfig The ifconfig command is used to configure, or view the configuration of, network interfaces, which includes displaying the IPv4 address associated with each network interface. It

provides a clear and comprehensive overview of network settings.

Option B is incorrect because hostname -I displays all network addresses on the host, which can be confusing if multiple addresses are returned.

Option C is incorrect because iwconfig is used for configuring wireless network interfaces and does not typically display IPv4 addresses for wired connections.

Option D is incorrect because sudo lshw -C network lists detailed information about network hardware and does not focus on displaying network configurations like IPv4 addresses.
