17. What use case involves providing optimized network paths and bandwidth allocation for different types of traffic, such as voice, video, and data?

The use case that involves providing optimized network paths and bandwidth allocation for different types of traffic, such as voice, video, and data, is known as Quality of Service (QoS).

Here are the steps to explain this use case:

1. Identification: The first step is to identify the different types of traffic that will be transmitted over the network. This typically includes voice, video, and data traffic.

2. Classification: The next step is to classify these different types of traffic. This is done based on their requirements for bandwidth, latency, jitter, and packet loss. For example, voice and video traffic usually require higher bandwidth and lower latency compared to data traffic.

3. Policy Creation: After classification, policies are created for each type of traffic. These policies define how each type of traffic should be treated in terms of priority, bandwidth allocation, and path selection.

4. Implementation: The policies are then implemented on the network devices. This involves configuring the devices to recognize the different types of traffic and apply the appropriate policies.

5. Monitoring and Adjustment: The final step is to monitor the network to ensure that the policies are being correctly applied and that
