A telecom company has installed radio devices across the country. On a daily basis, they are looking to collect logs from these thousands of devices & analyze them further to monitor faults & uptime trends. For analysis of logs, they are planning to use Amazon Redshift. No additional processing needs to be done on these logs. The company is concerned about collecting data & sending compressed data to Amazon Redshift & is looking for a scalable solution without any ad-hoc administration.
Which of the following services can be used to meet this requirement?

Answer options:

A.Create an Amazon Kinesis Streams, save compressed data in Amazon EC2 and then copy data to Amazon Redshift.
B.Create an Amazon Kinesis Data Firehose Delivery Stream, save compressed data in the Amazon S3 bucket and then copy data to Amazon Redshift.
C.Create an Amazon Kinesis Data Firehose Delivery Stream, save compressed data in Amazon EC2 and then copy data to Amazon Redshift.
D.Create an Amazon Kinesis Streams, save compressed data in the Amazon S3 bucket and then copy data to Amazon Redshift.

Correct Answer: B
Amazon Kinesis Data Firehose can be used to deliver data from thousands of sources to AWS service for further analysis. In the above case, the telecom company will use Amazon Redshift as an analytical service, so Amazon Kinesis Data Firehose Delivery Stream can be created to collect logs from thousands of radio devices. Amazon Kinesis Data Firehose cannot directly send data logs to Amazon Redshift but needs to first store in the Amazon S3 bucket & then it copies data to Amazon Redshift.
Amazon Kinesis Data Firehose is used when real-time streaming data is required to be delivered to destinations like Amazon S3 bucket, Amazon Redshift, Amazon OpenSearch (Amazon ES), and AWS Splunk. While delivering data to destinations, it supports the transformation of data like compression, batch, or encryption. Amazon Kinesis Data Firehose stores data only up to 24 hours if the destination is unavailable.
Options A and D are incorrect as the telecom company is not looking for additional processing or storing logs as all these logs would be generated daily. Creating Amazon Kinesis Data Firehose Delivery Stream is a better option than using Amazon Kinesis Streams.
Option C is incorrect as Amazon Kinesis Data Firehose cannot save data to the Amazon EC2 instance.
