Question 5 Which switch characteristic helps alleviate network congestion when a 10 Gbps port is forwarding data to a 1 Gbps port? Fast internal switching High port density Fast port speed Frame buffering

** Frame buffering

**Network congestion can occur when a high-speed port (such as a 10 Gbps port) is forwarding data to a lower-speed port (such as a 1 Gbps port). The switch must manage the difference in data transfer rates to ensure efficient communication and prevent data loss. Let's analyze each option to determine which characteristic helps alleviate this issue:1. **Fast internal switching:** This refers to the speed at which the switch can process and forward frames within the switch itself. While it improves overall performance, it does not directly address the mismatch in port speeds.2. **High port density:** This means having a large number of ports on the switch. While it allows for more devices to be connected, it does not specifically help with the congestion issue caused by a speed mismatch between ports.3. **Fast port speed:** This indicates that the ports on the switch can operate at high speeds. However, if there is a significant difference in speed between the ports, this alone cannot resolve the congestion problem.4. **Frame buffering:** This involves storing frames in a buffer before they are forwarded to another port. By buffering the frames, the switch can manage the data flow more effectively, especially when there is a difference in port speeds. This helps prevent data loss and ensures smooth communication even when there is a mismatch in data transfer rates.Given these explanations, the characteristic that specifically helps alleviate network congestion when a 10 Gbps port is forwarding data to a 1 Gbps port is **frame buffering**.**
