Question
A company is building an inventory management system and an inventory reordering system to automatically reorder products. Both systems use Amazon Kinesis Data Streams. The inventory management system uses the Amazon Kinesis Producer Library (KPL) to publish data to a stream. The inventory reordering system uses the Amazon Kinesis Client Library (KCL) to consume data from the stream. The company configures the stream to scale up and down as needed. Before the company deploys the systems to production, the company discovers that the inventory reordering system received duplicated data. Which factors could have caused the reordering system to receive duplicated data? (Choose two.)
Options
- AThe producer experienced network-related timeouts.
- BThe stream's value for the IteratorAgeMilliseconds metric was too high.
- CThere was a change in the number of shards, record processors, or both.
- DThe AggregationEnabled configuration property was set to true.
- EThe max_records configuration property was set to a number that was too high.
