Amazon AWS Certified DevOps Engineer - Professional Sample Questions (Q97-Q102):

NEW QUESTION # 97
When using Amazon SQS how much data can you store in a message?

  • A. 4 KB
  • B. 2 KB
  • C. 16 KB
  • D. 8 KB

Answer: D

Explanation:
With Amazon SQS version 2008-01-01, the maximum message size for both SOAP and Query requests is
8KB. If you need to send messages to the queue that are larger than 8 KB, AWS recommends that you split the information into separate messages. Alternatively, you could use Amazon S3 or Amazon SimpleDB to hold the information and include the pointer to that information in the Amazon SQS message. If you send a message that is larger than 8KB to the queue, you will receive a MessageTooLong error with HTTP code 400.


NEW QUESTION # 98
A production account has a requirement that any Amazon EC2 instance that has been logged into manually must be terminated within 24 hours. All applications in the production account are using Auto Scaling groups with Amazon CloudWatch Logs agent configured.
How can this process be automated?

  • A. Create a CloudWatch alarm that will trigger on the login event. Configure the alarm to send to an Amazon SQS queue. Use a group of worker instances to process messages from the queue, which then schedules the Amazon CloudWatch Events rule to trigger.
  • B. Create a CloudWatch Logs subscription to an AWS Step Functions application. Configure the function to add a tag to the EC2 instance that produced the login event and mark the instance to be decommissioned. Then create a CloudWatch Events rule to trigger a second AWS Lambda function once a day that will terminate all instances with this tag.
  • C. Create a CloudWatch alarm that will trigger on the login event. Send the notification to an Amazon SNS topic that the Operations team is subscribed to, and have them terminate the EC2 instance within 24 hours.
  • D. Create a CloudWatch Logs subscription in an AWS Lambda function. Configure the function to add a tag to the EC2 instance that produced the login event and mark the instance to be decommissioned.
    Create a CloudWatch Events rule to trigger a daily Lambda function that terminates all instances with this tag.

Answer: A


NEW QUESTION # 99
If Ansible encounters a resource that does not meet the requirements specified in the play it makes the necessary changes to the resource; however if the resource is already in the desired state Ansible will do nothing. This is an example of which methodology?

  • A. Convergence
  • B. Infrastructure as Code
  • C. Idempotency
  • D. Immutability

Answer: C

Explanation:
Idempotency states that changes are only made if a resource does not meet the requirement specifications. If a change is made, it is made `in-place' and will not break existing resources.

NEW QUESTION # 100
A DevOps Engineer has been asked to recommend a tool to deploy the components of a threetier web application. This application will use Amazon DynamoDB as a database Which deployment requires the LEAST amount of operational management?

  • A. Use AWS OpsWorks to create a Classic Load Balancer Auto Scaling and application resources Use AWS CloudFormation to create the database resources Deploy application updates using CloudFormation rolling updates
  • B. Use AWS OpsWorks to create a Classic Load Balancer, an Auto Scaling group application, and database resources Deploy application updates using OpsWorks lifecycle events
  • C. Use AWS CloudFormation to create a Classic Load Balancer and an Auto Scaling group. Use AWS OpsWorks to create the application and database resources Deploy application updates with OpsWorks using lifecycle events
  • D. Use AWS CloudFormation to create a Classic Load Balancer an Auto Scaling group and database resources Deploy application updates using CloudFormation rolling updates

Answer: B


NEW QUESTION # 101
A company has a hybrid architecture solution in which some legacy systems remain on-premises, while a specific cluster of servers is moved to AWS. The company cannot reconfigure the legacy systems, so the cluster nodes must have a fixed hostname and local IP address for each server that is part of the cluster. The DevOps Engineer must automate the configuration for a six-node cluster with high availability across three Availability Zones (AZs), placing two elastic network interfaces in a specific subnet for each AZ. Each node's hostname and local IP address should remain the same between reboots or instance failures. Which solution involves the LEAST amount of effort to automate this task?

  • A. Create an Amazon DynamoDB table with the list of hostnames subnets, and elastic network interfaces to be used. Create a single AWS CloudFormation template to manage an Auto Scaling group with a minimum size of 6 and a maximum size of 6. Create a programmatic solution that is installed in each instance that will lock/release the assignment of each hostname and local IP address, depending on the subnet in which a new instance will be launched.
  • B. Create an AWS Elastic Beanstalk application and a specific environment for each server of the cluster.
    For each environment, give the hostname, elastic network interface, and AZ as input parameters.
    Use the local health agent to name the instance and attach a specific elastic network interface based on the current environment.
  • C. Create a reusable AWS CLI script to launch each instance individually, which will name the instance, place it in a specific AZ, and attach a specific elastic network interface. Monitor the instances and in the event of failure, replace the missing instance manually by running the script again.
  • D. Create a reusable AWS CloudFormation template to manage an Amazon EC2 Auto Scaling group with a minimum size of 1 and a maximum size of 1. Give the hostname, elastic network interface, and AZ as stack parameters. Use those parameters to set up an EC2 instance with EC2 Auto Scaling and a user data script to attach to the specific elastic network interface. Use CloudFormation nested stacks to nest the template six times for a total of six nodes needed for the cluster, and deploy using the master template.
