An Application Running on Amazon EC2 Instances Generates Log Files

question 157

Multiple Choice

An application running on Amazon EC2 instances generates log files in a folder on a Linux file system. The instances block access to the console and file transfer utilities, such as Secure Copy Protocol (SCP) and Secure File Transfer Protocol (SFTP) . The Application Support team wants to automatically monitor the application log files so the team can set up notifications in the future. A Security Engineer must design a solution that meets the following requirements: Make the log files available through an AWS managed service. Allow for automatic monitoring of the logs. Provide an interface for analyzing logs. Minimize effort. Which approach meets these requirements?

• A) Modify the application to use the AWS SDK. Write the application logs to an Amazon S3 bucket.
• B) Install the unified Amazon CloudWatch agent on the instances. Configure the agent to collect the application log files on the EC2 file system and send them to Amazon CloudWatch Logs.
• C) Install AWS Systems Manager Agent on the instances. Configure an automation document to copy the application log files to AWS DeepLens.
• D) Install Amazon Kinesis Agent on the instances. Stream the application log files to Amazon Kinesis Data Firehose and set the destination to Amazon Elasticsearch Service.
