NEW QUESTION # 129
Your company releases new features with high frequency while demanding high application availability.
As part of the application's A/B testing, logs from each updated Amazon EC2 instance of the application need to be analyzed in near real-time, to ensure that the application is working flawlessly after each deployment. If the logs show arty anomalous behavior, then the application version of the instance is changed to a more stable one.
Which of the following methods should you use for shipping and analyzing the logs in a highly available manner?
- A. Ship the logs to Amazon CloudWatch Logs and use Amazon EMR to analyze the logs in a batch manner each hour.
- B. Ship the logs to a large Amazon EC2 instance and analyze the logs in a live manner.
- C. Store the logs locally on each instance and then have an Amazon Kinesis stream pull the logs for live analysis.
- D. Ship the logs to Amazon S3 for durability and use Amazon EMR to analyze the logs in a batch manner each hour.
- E. Ship the logs to an Amazon Kinesis stream and have the consumers analyze the logs in a live manner.

NEW QUESTION # 130
You currently run your infrastructure on Amazon EC2 instances behind an Auto Scalinggroup. All logs for your application are currentl\ written to ephemeral storage. Recently your company experienced a major bug in the code that made it through testing and was ultimately deployed to your fleet. This bug triggered your Auto Scalinggroup to scale up and back down before you could successfully retrieve the logs off your server to better assist you in troubleshooting the bug. Which technique should you use to make sure you are able to review your logs after your instances have shut down?
- A. Install the CloudWatch Logs Agent on your AMI, and configure CloudWatch Logs Agent to stream your logs. V
- B. Install the CloudWatch monitoring agent on your AMI, and set up new SNS alert for CloudWatch metrics that triggers the CloudWatch monitoring agent to backup all logs on the ephemeral drive.
- C. Configure the ephemeral policies on your Auto Scaling group to back up on terminate.
- D. Configure your Auto Scaling policies to create a snapshot of all ephemeral storage on terminate.
Answer: A
Explanation:
Explanation
You can use Cloud Watch Logs to monitor applications and systems using log data. For example, CloudWatch Logs can track the number of errors that occur in your application logs and send you a notification whenever the rate of errors exceeds a threshold you specify.
CloudWatch Logs uses your log data for monitoring; so, no
code changes are required.
Option A and B are invalid because Autoscaling policies are not designed for these purposes.
Option D is invalid because you use Cloudwatch Logs Agent and not the monitoring agent.
