Network Layer Question & Answers December 12, 2022 By WatElectronics This article lists 50 Network Layer MCQs for engineering students. All the Network Layer Questions & Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of the Network Layer. The network layer of a datagram-oriented network such as the internet has network protocol, path determination, and error reporting components. The host-to-host delivery and finding a path to the destination are the main responsibilities of the network layer. The routing, logical addressing, fragmentation & reassembly, datagram encapsulation, error handling & diagnostics are the key responsibilities of the network layer. The store and forward packet switching, Implementation of connectionless and connection-oriented services are the network layer design issues. The circuit setup is not needed in the datagram subnet whereas in the virtual circuit subnet the circuit setup is required. The quality of service and congestion control is difficult in the datagram subnet whereas it is easy in the virtual circuit if enough resources can be allocated in advance for each virtual circuit. The correctness, robustness, fairness, optimality, fairness, stability, & simplicity are the properties of a routing algorithm. The messages between local or remote devices are the scope of the network layer. The IP, IPV6, IPNAT, IPsec, ICMP, DLC, DLP, and routing protocols such as RIP and BGP are the common protocols and technologies in the network layer. 1).
