• CWorkstation name
• DLoopback address

• C

• D

Explanation

Default gateway is a required TCP/IP setting because it tells the computer where to send traffic destined for networks outside its own subnet - without it, the laptop can reach local devices but cannot communicate with the Internet or other network segments.

Why the distractors are wrong:

• A (MAC address): This is a hardware address burned into the network adapter itself; it is not manually configured as a TCP/IP setting.
• C (Workstation name): This is a computer/host name used for identification, but it is not part of the TCP/IP protocol configuration stack.
• D (Loopback address): This is a reserved address (127.0.0.1) that always refers to the local machine; it is built into the TCP/IP stack and never manually configured.

Memory tip: Think of the default gateway as the "front door" of your network - you need an IP address to know where you live, a subnet mask to know your neighborhood, and a default gateway to know which door to use to leave. All three (plus DNS) are the core TCP/IP settings Sally would configure.
