Try a sample question

A static batching system groups 8 requests into a single batch. Request A needs 50 tokens, Request B needs 500 tokens. What is the primary throughput problem with static batching in this scenario?

A.Static batching cannot handle requests with different prompt lengths — it requires all inputs to be pre-padded to a uniform length before the batch can be assembled and dispatched to the GPU
B.Static batching requires all requests to have the same model temperature setting, meaning a batch with mixed sampling strategies must be split into separate per-temperature groups before scheduling
C.All 8 requests in the batch must wait for the longest request (500 tokens) to complete before the batch is released and new requests begin
D.GPU memory cannot accommodate variable-length outputs in a single batch because KV cache blocks must be contiguous and pre-allocated to the same maximum size for every sequence in the group
