Add the following multiple choice questions and answers and explanations verbatim (DO NOT change the given wording). ========================================== New Question 1: What is a primary disadvantage of the token bucket algorithm in network traffic management? Choice A: It cannot handle bursty traffic efficiently. Choice B: It ensures a steady output rate. Choice C: It requires monitoring the number of available tokens. Choice D: It leads to significant packet loss during high traffic. Correct answer: C Explanation: The token bucket algorithm requires monitoring the number of available tokens, which can add complexity to the network management system. ========================================== New Question 2: Which of the following is a common use case for the leaky bucket algorithm that was not previously covered? Choice A: Video streaming services managing initial buffering. Choice B: Voice over IP (VoIP) ensuring real-time audio transmission. Choice C: Content delivery networks prioritizing packet delivery. Choice D: Cloud services implementing flexible data rates. Correct answer: B Explanation: Voice over IP (VoIP) is a real-time application that benefits from the leaky bucket algorithm's ability to maintain a steady data flow, ensuring uninterrupted audio transmission without buffering delays. ========================================== New Question 3: How can the token bucket algorithm be adjusted to control the data rate in a network? Choice A: By changing the size of the data packets. Choice B: By modifying the rate at which tokens are added and the size of the bucket. Choice C: By increasing the number of queues in the network. Choice D: By implementing a fixed token addition rate regardless of traffic conditions. Correct answer: B Explanation: The token bucket algorithm's flexibility in controlling data rate is achieved by adjusting the rate at which tokens are added to the bucket and the overall size of the bucket, allowing for better management of traffic flow. ========================================== New Question 4: In the context of video streaming, how does the token bucket algorithm facilitate smooth playback? Choice A: By ensuring a constant data rate regardless of network conditions. Choice B: By preloading and buffering content through temporary data bursts. Choice C: By discarding excess video data during high traffic periods. Choice D: By implementing a steady, uniform output rate. Correct answer: B Explanation: The token bucket algorithm allows video streaming services to preload and buffer content by permitting temporary bursts of data, which helps in maintaining smooth playback even when network conditions fluctuate. ==========================================
