The operations team and the development team want a single place to view both operating system and application logs. How should you implement this using AWS services?

Answer options:

A.Using AWS CloudFormation, create a CloudWatch Logs group and send the operating system and application logs using the CloudWatch Logs Agent.
B.Using AWS CloudFormation and configuration management, set up remote logging to send events via UDP packets to CloudTrail.
C.Set up remote logging to send events to an Amazon Kinesis stream and forward these logs into Amazon CloudWatch Event or Amazon Redshift, depending on available analytic tools.
D.Using AWS CloudFormation, merge the application logs with the operating system logs, and use IAM Roles to allow both teams to have access to view the output from Amazon EC2 console.

Answer – A
Option B is incorrect because CloudTrail is not designed specifically to collect operation system or application logs.
Option C is incorrect because the Kinesis stream is more suitable for real-time data processing. CloudWatch Event is also not required in this scenario.
Option D is incorrect because it does not mention how to view the logs through the EC2 console. EC2 is not a suitable service for users to view the logs.
You can use Amazon CloudWatch Logs to monitor, store, and access your log files from Amazon Elastic Compute Cloud (Amazon EC2) instances, AWS CloudTrail, and other sources. You can then retrieve the associated log data from CloudWatch Logs.
