Which Junos OS command is used to display a list of active interfaces?

• A. show interfaces
• B. show ip interface
• C. show vlan
• D. show network status

Answer: (A)

The command "show interfaces" is used in Junos OS to provide a detailed view of all the interfaces on a device, including their status and statistics. This command lists both active and inactive interfaces, along with information about their operational state, such as whether they are up or down, the bandwidth available, and various other metrics that are crucial for network administrators. When you execute this command, it enables you to identify which interfaces are currently active (operational) and provides insights into their performance and configurations. The output includes vital statistics such as packet counts, error metrics, and throughput, which are essential for troubleshooting and monitoring network health. Other commands like "show ip interface," while relevant in certain contexts, do not exist in standard Junos OS syntax, making them less suitable for this purpose. Similarly, "show vlan" focuses on Virtual LAN configurations, and "show network status" does not specifically target interface information. Therefore, the command "show interfaces" is the most appropriate choice for displaying a comprehensive list of active interfaces.
