DOP-C01 Online Practice Questions and Answers
A retail company has adopted AWS OpsWorks for managing its deployments. In the last three months, the company has discovered that some production instances have been restarting without reason. Upon inspection of the AWS CloudTrail
logs, a DevOps Engineer determined that those instances were restarted by OpsWorks. The Engineer now wants automated email notifications whenever OpsWorks restarts an instance when the instance is deemed unhealthy or unable to
communicate with the service endpoint.
How can the Engineer meet this requirement?
A. Create a Chef recipe to place a cron to run a custom script within the Amazon EC2 instances that sends an email to the team by using Amazon SES if the OpsWorks agent detects an instance failure.
B. Create an Amazon SNS topic and create a subscription for this topic that contains the destination email address. Create an Amazon CloudWatch rule: specify aws.opsworks as a source and specify auto- healing in the initiated_by details. Use the SNS topic as a target.
C. Create an Amazon SNS topic and create a subscription for this topic that contains the destination email address. Create an Amazon CloudWatch rule: specify aws.opsworks as a source and specify instance-replacement in the initiated_by details. Use the SNS topic as a target.
D. Create a subscription for this topic that contains the email address. Enable instance restart notifications within the OpsWorks layer and indicate the destination email address for the notification.
You work for an insurance company and are responsible for the day-to-day operations of your company's online quote system used to provide insurance quotes to members of the public. Your company wants to use the application logs generated by the system to better understand customer behavior. Industry, regulations also require that you retain all application logs for the system indefinitely in order to investigate fraudulent claims in the future. You have been tasked with designing a log management system with the following requirements:
-All log entries must be retained by the system, even during unplanned instance failure.
-The customer insight team requires immediate access to the logs from the past seven days.
- The fraud investigation team requires access to all historic logs, but will wait up to 24 hours before these logs are available.
How would you meet these requirements in a cost-effective manner? (Choose three.)
A. Configure your application to write logs to the instance's ephemeral disk, because this storage is free and has good write performance. Create a script that moves the logs from the instance to Amazon 53 once an hour.
B. Write a script that is configured to be executed when the instance is stopped or terminated and that will upload any remaining logs on the instance to Amazon S3.
C. Create an Amazon S3 lifecycle configuration to move log files from Amazon S3 to Amazon Glacier after seven days.
D. Configure your application to write logs to the instance's default Amazon EBS boot volume, because this storage already exists. Create a script that moves the logs from the instance to Amazon 53 once an hour.
E. Configure your application to write logs to a separate Amazon EBS volume with the "delete on termination" field set to false. Create a script that moves the logs from the instance to Amazon S3 once an hour.
F. Create a housekeeping script that runs on a T2 micro instance managed by an Auto Scaling group for high availability. The script uses the AWS API to identify any unattached Amazon EBS volumes containing log files. Your housekeeping script will mount the Amazon EBS volume, upload all logs to Amazon S3, and then delete the volume.
What is the default maximum number of Roles per AWS account?
A. 500
B. 250
C. 100
D. There is no limit.

This dump is really good and helpful. I just passed the exam successfully. Only 2 questions were not included in the {sku} dumps. I cannot remember the question. And I'm not sure if I answered that question correctly. Never mind. I would pass the exam even leave those two questions blank. I also got many questions that are exactly the same as this dump. So be sure to go through the whole material carefully.

The {sku} is the most valid. I got all questions from these dumps and passed with a full score. I tried dumps from other sites, too. I think their dumps are really up to date and more accurate than others. Really a good choice for the one who does not have enough time to take the course. Really update questions. You may get new questions in a short time after the exam questions changed.
