Amazon AWS Certified DevOps Engineer - Professional Sample Questions (Q311-Q316):

NEW QUESTION # 311
There is a very serious outage at AWS. EC2 is not affected, but your EC2 instance deployment scripts stopped working in the region with the outage. What might be the issue?

  • A. AWS turns off the DeployCode API call when there are major outages, to protect from system floods.
  • B. The AWS Console is down, so your CLI commands do not work.
  • C. S3 is unavailable, so you can't create EBS volumes from a snapshot you use to deploy new volumes.
  • D. None of the other answers make sense. If EC2 is not affected, it must be some other issue.

Answer: C

Explanation:
Explanation
The CBS Snapshots are stored in S3, so if you have an scripts which deploy CC2 Instances, the CBS volumes need to be constructed from snapshots stored in S3.
You can back up the data on your Amazon CBS volumes to Amazon S3 by taking point-in-time snapshots.
Snapshots are incremental backups, which means that only
the blocks on the device that have changed after your most recent snapshot are saved. This minimizes the time required to create the snapshot and saves on storage costs by not duplicating data. When you delete a snapshot, only the data unique to that snapshot is removed. Cach snapshot contains all of the information needed to restore your data (from the moment when the snapshot was taken) to a new CBS volume.

NEW QUESTION # 312
You currently have EC2 Instances hosting an application. These instances are part of an Autoscaling Group.
You now want to change the instance type of the EC2 Instances. How can you manage the deployment with
the least amount of downtime

  • A. Use the Rolling Update feature which is available for EC2 Instances.
  • B. Use the AutoScalingRollingUpdate policy on CloudFormation Template Auto Scalinggroup
  • C. Manually terminate the instances, launch new instances with the new instance type and attach them to
    the Autoscaling group
  • D. Terminate the existing Auto Scalinggroup. Create a new launch configuration with the new Instance
    type. Attach that to the new Autoscaing Group.

Answer: B

Explanation:
Explanation
The AWS::AutoScaling::AutoScalingGroup resource supports an UpdatePolicy attribute. This is used to
define how an Auto Scalinggroup resource is updated when
an update to the Cloud Formation stack occurs. A common approach to updating an Auto Scaling group is to
perform a rolling update, which is done by specifying the
AutoScalingRollingUpdate policy. This retains the same Auto Scalinggroup and replaces old instances with
new ones, according to the parameters specified.

NEW QUESTION # 313
A company wants to adopt a methodology for handling security threats from leaked and compromised IAM access keys. The DevOps Engineer has been asked to automate the process of acting upon compromised access keys, which includes identifying users, revoking their permissions, and sending a notification to the Security team.
Which of the following would achieve this goal?

  • A. Use AWS Lambda with a third-party library to scan for compromised access keys. Use scan result inside AWS Lambda and delete compromised IAM access keys. Create Amazon CloudWatch custom metrics for compromised keys. Create a CloudWatch alarm on the metrics to notify the Security team.
  • B. Use AWS Trusted Advisor to identify compromised access keys. Create an Amazon CloudWatch Events rule with Trusted Advisor as the event source, and AWS Lambda and Amazon SNS as targets. Use AWS Lambda to delete compromised IAM access keys and Amazon SNS to notify the Security team.
  • C. Use the AWS Trusted Advisor generated security report for access keys. Use AWS Lambda to scan through the report. Use scan result inside AWS Lambda and delete compromised IAM access keys. Use Amazon SNS to notify the Security team.
  • D. Use the AWS Trusted Advisor generated security report for access keys. Use Amazon EMR to run analytics on the report. Identify compromised IAM access keys and delete them. Use Amazon CloudWatch with an EMR Cluster State Change event to notify the Security team.

NEW QUESTION # 314
A DevOps Engineer is responsible for the deployment of a PHP application. The Engineer is working in a hybrid deployment, with the application running on both on-premises servers and Amazon EC2 instances. The application needs access to a database containing highly confidential information. Application instances need access to database credentials, which must be encrypted at rest and in transit before reaching the instances.
How should the Engineer automate the deployment process while also meeting the security requirements?

  • A. Use AWS CodeDeploy to deploy application packages to the instances. Store database credentials in the AppSpec file. Define an IAM policy for allowing access to only the database credentials. Attach the IAM policy to the role associated to the instance profile for CodeDeploy-managed instances and the role used for on-premises instances registration on CodeDeploy.
  • B. Use AWS Elastic Beanstalk with a PHP platform configuration to deploy application packages to the instances. Store database credentials on AWS Systems Manager Parameter Store using the Secure String data type. Define an IAM role for Amazon EC2 allowing access, and decrypt only the database credentials.
    Associate this role to all the instances.
  • C. Use AWS CodeDeploy to deploy application packages to the instances. Store database credentials on AWS Systems Manager Parameter Store using the Secure String data type. Define an IAM role with an attached policy that allows decryption of the database credentials. Associate this role to all the instances and on-premises servers.
  • D. Use AWS CodeDeploy to deploy application packages to the instances. Store database credentials on AWS Systems Manager Parameter Store using the Secure String data type. Define an IAM policy for allowing access, and decrypt only the database credentials. Attach the IAM policy to the role associated to the instance profile for CodeDeploy-managed instances, and to the role used for on-premises instances registration on CodeDeploy.

Answer: D


NEW QUESTION # 315
A company is implementing an Amazon ECS cluster to run its workload. The company architecture will run multiple ECS services on the cluster, with an Application Load Balancer on the front end, using multiple target groups to route traffic. The Application Development team has been struggling to collect logs that must be collected and sent to an Amazon S3 bucket for near-real time analysis What must the DevOps Engineer configure in the deployment to meet these requirements? (Select THREE)

  • A. Download the Amazon CloudWatch Logs container instance from AWS and configure it as a task.
    Update the application service definitions to include the logging task.
  • B. Install the Amazon CloudWatch Logs logging agent on the ECS instances. Change the logging driver in the ECS task definition to 'awslogs'.
  • C. Use Amazon CloudWatch Events to schedule an AWS Lambda function that will run every 60 seconds running the create-export -task CloudWatch Logs command, then point the output to the logging S3 bucket.
  • D. Create an Amazon Kinesis Data Firehose with a destination of the S3 logging bucket, then create an Amazon CloudWatch Logs subscription filter for Kinesis.
  • E. Enable access logging on the Application Load Balancer, then point it directly to the S3 logging bucket.
  • F. Enable access logging on the target groups that are used by the ECS services, then point it directly to the S3 logging bucket.

Answer: B,C,F
