Why would a Layer 2 switch need an IP address?

• A. To allow data packet forwarding between multiple switches.
• B. To enable the switch to be managed remotely.
• C. To provide DHCP services for the connected devices.
• D. To facilitate VLAN tagging for network segmentation.

Answer: (B)

A Layer 2 switch requires an IP address primarily to enable remote management. By assigning an IP address to the switch, network administrators can access the device through protocols such as SSH, HTTP, or HTTPS. This management capability is crucial for performing configuration changes, monitoring performance statistics, and troubleshooting issues from a remote location rather than having to connect physically to the device. While other functions performed by switches, such as data packet forwarding, VLAN management, or DHCP services, are relevant to their operation, they do not inherently require a Layer 2 switch to have an IP address. For instance, switches operate at Layer 2 of the OSI model and primarily deal with MAC addresses for switching traffic within the same network segment. Also, while VLAN features and DHCP could be relevant, they don't necessitate an IP address for the switch itself to function in its primary role. Hence, enabling remote management is the key reason for assigning an IP address to a Layer 2 switch.
