What information does the command 'show interfaces' provide on a Cisco device?

• A. Status and statistics of all interfaces
• B. Only the connectivity status of the device
• C. List of all connected devices
• D. Routing information of the device

Answer: (A)

The command 'show interfaces' on a Cisco device is a powerful diagnostic tool that provides comprehensive information about all the interfaces on the device. This command displays the status and statistics for each interface, including whether the interface is up or down, the method of connection, the speed and duplex settings, and various performance metrics such as the number of packets transmitted and received, error counts, and interface thresholds. This detailed view allows network administrators to effectively monitor and troubleshoot the health and performance of network interfaces. By checking these statistics, administrators can quickly identify issues such as excessive errors that may indicate a physical layer problem, bandwidth utilization, or other interface-related concerns. Other options do not encompass the full range of information provided by the command. For example, simply reporting connectivity status would not include performance metrics or the specifics of each interface's activity, and listing connected devices or routing information would require different commands than 'show interfaces'. Thus, the command is primarily focused on interface status and statistics, making it an essential tool for managing Cisco devices in a network environment.
