Which network configuration allows multiple servers to connect without needing individual network information?

The Layer 2 network configuration is specifically designed to allow multiple servers to connect seamlessly without requiring individual network information, such as unique IP addresses for each server. In a Layer 2 network, data packets are transmitted based on MAC addresses rather than IP addresses, which allows devices on the same local area network (LAN) to communicate directly. This is particularly beneficial in environments like data centers, where numerous servers might need to exchange data frequently and efficiently.

Layer 2 facilitates the communication by creating a simple and efficient method for data transfer using switches, which can understand and direct traffic based on MAC addresses. By utilizing VLANs (Virtual Local Area Networks), multiple servers can be grouped logically, helping manage traffic without complicating individual network configuration for each device. This reduces the overhead of network management and simplifies the deployment of new servers or devices within the network, as they can often be added without extensive configuration.

In contrast, Layer 3 relies on IP addresses for routing data between networks, which introduces additional complexity since each device typically requires a distinct address. Layers 4 and higher introduce additional features like transport protocols and session management, which are not needed for basic local communication. Therefore, Layer 2 is the most appropriate choice when the goal is simple, internal network
