65.A company has an infrastructure that consists of machines which keep sending log information every 5 minutes.
The number of these machines can run into thousands and it is required to ensure that the data can be analyzed at a later stage. Which of the following would help in fulfilling this requirement?
A. Use Kinesis Firehose with S3 to take the logs and store them in S3 for furtherprocessing.
B. Launch an Elastic Beanstalk application to take the processing job of the logs.
C. Launch an EC2 instance with enough EBS volumes to consume the logs which can be usedof r further processing.
