💡 Difficulty: easy | ✅ Correct: B

Q2. A node receives a complete message before it can forward any part of it to the next node. Which switching technique is being employed, and what is its main disadvantage?

💡 Difficulty: medium | ✅ Correct: B

Q3. Assume a network where each link has a capacity of 10 Mbps and the average packet size is 10 KB. Using the formula \( \text{utilization} = \frac{\text{average\_packet\_size}}{\text{capacity} \times \text{inter‑arrival\_time}} \), which switching method would most likely keep utilization below 30 % under bursty traffic?

💡 Difficulty: hard | ✅ Correct: C
