How does the link layer differ from the network layer (e.g. IP) in terms of the scope of its responsibilities?

		The link layer is responsible for end-to-end data delivery, while the network layer only handles local hop-by-hop transfer.
		The link layer is responsible for transferring data between physically adjacent nodes, while the network layer handles end-to-end routing.
		There is no difference - the link and network layers have identical responsibilities.
