Exam question from Amazon's AWS Certified DevOps Engineer - Professional DOP-C02
Question #: 217
Topic #: 1
[All AWS Certified DevOps Engineer - Professional DOP-C02 Questions]

A company has an application that runs on AWS Lambda and sends logs to Amazon CloudWatch Logs. An Amazon Kinesis data stream is subscribed to the log groups in CloudWatch Logs. A single consumer Lambda function processes the logs from the data stream and stores the logs in an Amazon S3 bucket.

The company’s DevOps team has noticed high latency during the processing and ingestion of some logs.

Which combination of steps will reduce the latency? (Choose three.)

  • A. Create a data stream consumer with enhanced fan-out. Set the Lambda function that processes the logs as the consumer.
  • B. Increase the ParallelizationFactor setting in the Lambda event source mapping.
  • C. Configure reserved concurrency for the Lambda function that processes the logs.
  • D. Increase the batch size in the Kinesis data stream.
  • E. Turn off the ReportBatchItemFailures setting in the Lambda event source mapping.
  • F. Increase the number of shards in the Kinesis data stream.

A: Kinesis Enhanced fan-out is an Amazon Kinesis Data Streams feature that enables consumers to receive records from a data stream with dedicated throughput of up to 2 MB of data per second per shard. A consumer that uses enhanced fan-out doesn't have to contend with other consumers that are receiving data from the stream. B: Reserved concurrency – This represents the maximum number of concurrent instances allocated to your function. When a function has reserved concurrency, no other function can use that concurrency. Reserved concurrency is useful for ensuring that your most critical functions always have enough concurrency to handle incoming requests. F: The data capacity of your stream is a function of the number of shards that you specify for the stream. The total capacity of the stream is the sum of the capacities of its shards.
