When configuring interfaces, which command is essential for defining the speed of an interface?

• A. set speed
• B. speed
• C. configure speed
• D. speed value

Answer: (B)

The command used to define the speed of an interface in Cisco devices is simply "speed" followed by the desired speed value. This command is applied within the interface configuration mode, allowing you to set the operational speed of an Ethernet interface, for example, to match network requirements or to align with the capabilities of connected devices. The use of "speed" is standardized across Cisco IOS systems, making it a key command for network administrators to manage interface settings effectively. Specifying the speed can help ensure proper data transmission rates and avoid potential connectivity issues that can arise from mismatched speeds between devices. Understanding this command is crucial for configuring and troubleshooting network interfaces, as it directly impacts the performance and reliability of network connections.
