Network Layer — CompTIA Network+ (N10-009) Practice Questions
The network layer corresponds to Layer 3 of the OSI model and is responsible for logical addressing and routing packets between hosts across different networks. On the Network+ N10-009 exam, you must understand how IP addressing, subnetting, routing protocols, and packet forwarding operate at this layer. The network layer is where routers operate, making decisions about the best path for data to travel based on destination IP addresses and routing tables. Questions frequently test the distinction between Layer 3 functions and those of adjacent layers, as well as how protocols like IP, ICMP, and OSPF function within this context.
