Which protocol provides addressing and routing at the Internet layer in the TCP/IP suite?

• A. REST
• B. on-premises network
• C. IP
• D. VLAN

Answer: (C)

The thing being tested is how addressing and routing are handled in the TCP/IP model. In the Internet layer, the primary function is to provide a way to identify devices across different networks and to move packets from their source to their destination through routers. The protocol that does this is IP—the Internet Protocol. It assigns logical addresses (IP addresses) to devices and uses routing to forward packets across networks to reach the right destination, handling the end-to-end delivery across multiple networks. REST is an application-layer approach used for web services, not for core network addressing or routing. A VLAN is a method to segment a local network at the data-link layer, improving traffic management within a single broadcast domain rather than enabling inter-network routing. An on-premises network describes a deployment location or model, not a protocol responsible for addressing and routing.
