EIGRP and OSPF Questions and Answers
EIGRP and OSPF questions with answers are essential for students preparing for networking-based aptitude tests and IT placement exams. These routing protocols—Enhanced Interior Gateway Routing Protocol (EIGRP) and Open Shortest Path First (OSPF)—form the backbone of dynamic routing in computer networks. Understanding how they differ in metrics, convergence, and scalability helps candidates tackle technical questions confidently during interviews or online tests. Many top companies like Cisco, Wipro, and Infosys include EIGRP and OSPF aptitude questions in their placement exams to assess core networking skills. This section covers key multiple-choice questions, explanations, and examples to help you master routing concepts, prepare for certifications, and practice effectively for networking interviews or competitive exams.
EIGRP and OSPF
21. Why does the data communication industry use the layered OSI reference model? It divides the network communication process into smaller and simpler components, thus aiding component development, design, and troubleshooting. It enables equipment from different vendors to use the same electronic components, thus saving research and development funds. It supports the evolution of multiple competing standards and thus provides business opportunities for equipment manufacturers. It encourages industry standardization by defining what functions occur at each layer of the model.

22. A receiving host has failed to receive all of the segments that it should acknowledge. What can the host do to improve the reliability of this communication session?
- Send a different source port number.
- Restart the virtual circuit.
- Decrease the sequence number.
- Decrease the window size.

- 69/0x2102
- 183/B7
- 173/A6
- 83/0xC5
24. What is the purpose of flow control?
- To ensure that data is retransmitted if an acknowledgment is not received.
- To reassemble segments in the correct order at the destination device.
- To provide a means for the receiver to govern the amount of data sent by the sender.
- To regulate the size of each segment.
25. Which three statements are true about the operation of a full-duplex Ethernet network? There are no collisions in full-duplex mode. A dedicated switch port is required for each full-duplex node. Ethernet hub ports are preconfigured for full-duplex mode. In a full-duplex environment, the host network card must check for the availability of the network media before transmitting. The host network card and the switch port must be capable of operating in full-duplex mode.
