Which layer of the OSI model is responsible for logical addressing and routing ?
Answer: B
Logical addressing and routing are the job of the Network Layer.
The network layer (layer 3 of the OSI model) assigns logical addresses such as IP addresses and chooses routes for packets across interconnected networks; routers work at this layer.
The transport layer provides end-to-end delivery, the data link layer handles physical (MAC) addressing within a network, and the application layer serves user applications.
