Quiz6 Kinesis Analytics
Question 1
From which sources can the input for Kinesis analytics be obtained ?
- MySQL and Kinesis Data Streams
- DynamoDB and Kinesis Firehose deliver streams
- Kinesis data streams and Kinesis Firehose delivery streams
- Kinesis Data Streams and DynamoDB
Kinesis Analytics can only monitor streams from Kinesis, but both data streams and Firehose are supported.
Question 2
After real-time analysis has been performed on the input source, where may you send the processed data for further processin ?
- Amazon S3
- Redshift
- Athena
- Kinesis Data Stream or Firehose
- All of the above
While you might in turn connect S3 or Redshift to your Kinesis Analytics output stream, Kinesis Analytics must have a stream as its input, and a stream or Lambda function as its output.
Question 3

- The record is written to the error stream
- The record is processed with the late timestamp
- The record is discarded entirely
- None of the above
Application error stream:
Certain records like a type mismatch or late arrival wiil be written out to the erro stream.
Question 4
You have heard from your AWS consultant that Amazon Kinesis Data Analytics elastically scales the application to accommodate the data a-IVUULpUa. What though is defaultfault capacity of the processing application in terms of memory?
- 48GB
- 12GB
- 24GB
- 32GB
Kinesis Data Analytics provisions capacity in the form of Kinesis Processing Units (KPU). A single KPU provides you with the memory (4 GB) and corresponding computing and networking. The default limit for KPUs for your application is eight.
Question 5
You have configured data analytics and have been streaming the source data to the application. You have also configured the destination correctly. However, even after waiting for a while, you are not seeing any data come up in the destination. What might be a possible cause?
- Issue with IAM role
- Mismatched name for the output stream
- Destination service is currently unavailable
- Any of the above
