Free Amazon DOP-C01 Exam Dumps Questions & Answers

You're responsible for a popular file sharing application that uses Elastic Load Balancing to distribute traffic to an Amazon EC2 application tier deployed in an Auto Scaling group that runs across multiple Availability Zones.
You currently record the number of user file transfers to a log file on the application server, and then write data points from the logs to an Amazon RDS MySQL instance.
You aren't happy with how your application scales, and want to implement a new scaling policy based on the average number of user file transfers in a 10-minute period instead of average CPU utilization in the last five minutes.
What steps should you take to ensure that your application tier scales based on this new policy?
Choose 2 answers

• A.  Create a new CloudWatch alarm based on the Elastic Load Balancing "RequestCount" metric that triggers an Auto Scaling action to scale the application tier.
• B.  Create a new CloudWatch alarm based on a custom metric streaming from the Amazon RDS MySQL instance that triggers an Auto Scaling action to scale the application tier.
• C.  Create a new Auto Scaling launch configuration that includes an Amazon EC2 user data script that installs a CloudWatch Logs Agent on newly launched instances in the application tier. The agent will be configured to stream the file transfers log tile to CloudWatch.
• D.  Create a new Auto Scaling launch configuration that includes an Amazon EC2 user data script that installs an Amazon RDS Logs Agent on newly launched instances in the application tier. The agent will be configured to stream the file transfer data points to the Auto Scaling group.
• E.  Create a new Auto Scaling launch configuration for the application tier that scales based on an Auto Scaling policy that reads the file transfer log data from the Amazon RIDS MySQL instance.
• F.  Create a new CloudWatch alarm based on a custom metric published from file transfer logs streaming to CloudWatch that triggers an Auto Scaling action to scale the application tier.

You are building a Docker image with the following Dockerfile. How many layers will the resulting image have?
FROM scratch
CMD /app/hello.sh

• A.  1
• B.  4
• C.  2
• D.  3

You are designing an enterprise data storage system. Your data management software system requires mountable disks and a real filesystem, so you cannot use S3 for storage. You need persistence, so you will be using AWS EBS Volumes for your system. The system needs as low- cost storage as possible, and access is not frequent or high throughput, and is mostly sequential reads. Which is the most appropriate EBS Volume Type for this scenario?

• A.  gp2
• B.  gp1
• C.  standard
• D.  io1

A company mandates the creation of capture logs for everything running in its AWS account. The account has multiple VPCs with Amazon EC2 instances, Application Load Balancers, Amazon RDS MySQL databases, and AWS WAF rules configured. The logs must be protected from deletion. A daily visual analysis of log anomalies from the previous day is required.
Which combination of actions should a DevOps Engineer take to accomplish this? (Choose three.)

• A.  Configure Amazon S3 MFA Delete on the logging Amazon S3 bucket.
• B.  Configure AWS Artifact to send all logs to the logging Amazon S3 bucket. Create a dashboard report in Amazon QuickSight.
• C.  Deploy an Amazon CloudWatch agent to all Amazon EC2 instances.
• D.  Configure an AWS Lambda function to send all CloudWatch logs to an Amazon S3 bucket.
  Create a dashboard report in Amazon QuickSight.
• E.  Configure an Amazon S3 object lock legal hold on the logging Amazon S3 bucket.
• F.  Configure AWS CloudTrail to send all logs to Amazon Inspector. Create a dashboard report in Amazon QuickSight.

The management team at a company with a large on-premises OpenStack environment wants to move non-production workloads to AWS. An AWS Direct Connect connection has been provisioned and configured to connect the environments. Due to contractual obligations, the production workloads must remain on-premises, and will be moved to AWS after the next contract negotiation. The company follows Center for Internet Security (CIS) standards for hardening images; this configuration was developed using the company's configuration management system.
Which solution will automatically create an identical image in the AWS environment without significant overhead?

• A.  Log in to the console, launch an Amazon EC2 instance, and install the configuration management agent. When changes are applied through the configuration management system, log in to the console and create a new AMI from the instance.
• B.  Write an AWS CloudFormation template that will create an Amazon EC2 instance. Use cloud-unit to install the configuration management agent, use cfn-wait to wait for configuration management to successfully apply, and use an AWS Lambda-backed custom resource to create the AMI.
• C.  Create a new AWS OpsWorks layer and mirror the image hardening standards. Use this layer as the baseline for all AWS workloads.
• D.  When a change is made in the configuration management system, a job in Jenkins is triggered to use the VM Import command to create an Amazon EC2 instance in the Amazon VPC. Use lifecycle hooks to launch an AWS Lambda function to create the AMI.
