Answer: Scenario 1

Scenario 1 will induce the least network traffic during a shuffle operation because it uses a single node with all 200 cores and 100GB RAM. Since all data processing occurs within a single node, shuffle operations do not require data transfer across the network between different nodes. In contrast, all other scenarios involve multiple nodes, which would require network traffic during shuffle operations as data needs to be exchanged between nodes. The community discussion confirms this reasoning with 100% consensus on answer C, noting that 'all the data would stay within the single node, avoiding any cross-node traffic.'
