[https://www.certkillers.net](https://www.certkillers.net) Questions & Answers PDF Page 3 A. monitor traffic absolute-sequence B. monitor interface traffic C. monitor traffic D. show interfaces extensive Answer: B Explanation: To view real-time usage statistics for the busiest interfaces on a device running Junos OS, the correct command is B, "monitor interface traffic. " This command provides a dynamic, real-time view of the traffic flowing through the interfaces, allowing administrators to quickly identify and monitor the busiest interfaces on the device. Question: 3 Which type of device uses the destination IP address to forward packets? A. Layer 3 router B. Layer 2 switch C. repeater D. hub Answer: A Explanation: A Layer 3 router forwards packets based on the destination IP address. It operates at the network layer of the OSI model and uses routing tables to determine the best path for packet delivery. Unlike Layer 2 switches, which forward packets based on MAC addresses, routers handle logical addressing, making them crucial for inter-network communication.
