During a remote support session, a macOS user needs to check whether their Ethernet connection is configured to obtain an IP address via DHCP. Which ifconfig option should the technician guide the user to use in order to find this specific information?
Correct Answer: B
Correct Answer. B. ifconfig en0 ifconfig en0 provides detailed information about the Ethernet interface (typically en0), including whether it is set to receive an IP via DHCP (look for "inet" which includes the IP address and "status: active" to indicate it is operational). This command targets the specific interface likely to be used for Ethernet connections. Option A is incorrect because ifconfig getifaddr en0 retrieves only the IP address assigned to the Ethernet interface, without indicating whether it's obtained via DHCP. Option C is incorrect because ifconfig en1 might not be the correct interface for Ethernet if en0 is the designated Ethernet interface; en1 often refers to Wi-Fi. Option D is incorrect because ifconfig list is not a valid command to view detailed information about specific network interfaces in macOS.
