Delete the existing Standard queue and create a new FIFO queue is required because SQS does not allow converting a Standard queue into FIFO. You must stand up a new FIFO queue and migrate producers and consumers. Ensure the FIFO queue name ends with the .fifo suffix is mandatory, as SQS identifies FIFO queues by the .fifo suffix on the queue name. Confirm the target FIFO queue throughput with batching stays at or below 3,000 messages per second aligns with the documented FIFO throughput quota when using batch operations. Without batching, the limit is 300 messages per second. Ensure the throughput for the target FIFO queue does not exceed 300 messages per second is not appropriate in this context because the team plans to use batching, which raises the limit to 3,000 messages per second. Convert the current Standard queue directly into a FIFO queue is impossible since SQS does not support in-place conversion between Standard and FIFO types. Replace the SQS Standard queue with Amazon MQ to achieve strict ordering is a distractor because Amazon MQ is a separate managed broker service and is not part of an SQS-to-SQS migration path. When you see SQS FIFO on the exam, remember three cues: the .fifo name suffix, no in-place conversion from Standard to FIFO, and the throughput numbers of 300 without batching versus 3,000 with batching.
