Which of the following does OSI Layer 2 NOT provide?

The OSI Layer 2, which is the Data Link Layer, does not provide routing capabilities. Its primary functions are to ensure reliable data transfer across a physical network, manage how data packets are framed and addressed, and control how devices on the same local network segment access physical media.

Error checking is a crucial function of Layer 2, allowing devices to detect and possibly correct errors that may occur during the transmission of information. Framing rules are also a key aspect of Layer 2, as this layer defines how data is packaged into frames for transmission across the physical media. Media access control is another integral function of Layer 2, determining how different devices on a shared medium communicate and avoid collisions.

Routing, however, takes place at Layer 3 of the OSI model, which is known as the Network Layer. This is where logical addressing and the processes for routing data packets between different networks occur. Therefore, stating that Layer 2 provides routing capabilities is inaccurate, making it the correct answer to the question.
