What does the command ip default-gateway 172.16.100.1 accomplish when applied to a switch?

• A. The switch is assigned a new IP address.
• B. The switch gains internet access directly.
• C. The switch can be remotely managed from another network.
• D. The switch routes traffic between VLANs.

Answer: (C)

The command "ip default-gateway 172.16.100.1" configures the switch with a default gateway, which is essential for enabling the device to communicate with devices on different networks. When this command is applied, the switch will use the specified IP address as a path to forward traffic destined for networks that are not directly connected to it. This is particularly important for remote management. When the switch needs to send management traffic, such as SSH or Telnet sessions, to devices that are outside of its local subnet, it will forward that traffic to the default gateway. The default gateway serves as an intermediary that facilitates the necessary routing of data packets to other networks, allowing for remote management from an external network. In contrast, other potential interpretations of the command do not accurately reflect its function. The command does not assign a new IP address to the switch; instead, it establishes a pathway for routing traffic to external networks. Moreover, it does not directly provide internet access or allow the switch to route traffic between VLANs, which would require different configurations such as a Layer 3 switch setup or specific routing commands.
