Amazon AWS Certified DevOps Engineer - Professional Sample Questions (Q475-Q480):

NEW QUESTION # 475
You need to run a very large batch data processingjob one time per day. The source data exists entirely in S3, and the output of the processingjob should also be written to S3 when finished. If you need to version control this processingjob and all setup and teardown logic for the system, what approach should you use?.

  • A. Model an AWSEMRjob in AWS CloudFormation.
  • B. Model an AWS EMRjob in AWS OpsWorks.
  • C. Model an AWSEMRjob in AWS Elastic Beanstalk.
  • D. Model an AWS EMRjob in AWS CLI Composer.

Answer: A

Explanation:
Explanation
With AWS Cloud Formation, you can update the properties for resources in your existing stacks. These changes can range from simple configuration changes, such as updating the alarm threshold on a Cloud Watch alarm, to more complex changes, such as updating the Amazon Machine Image (AMI) running on an Amazon EC2 instance. Many of the AWS resources in a template can be updated, and we continue to add support for more.

NEW QUESTION # 476
A DevOps engineer is assisting with a multi-Region disaster recovery solution for a new application. The application consists of Amazon EC2 instances running in an Auto Scaling group and an Amazon Aurora MySQL DB cluster. The application must be available with an RTO of 120 minutes and an RPO of 60 minutes.
What is the MOST cost-effective way to meet these requirements?

  • A. Launch an Aurora DB cluster as an Aurora Replica in a different Region.
    Create an AWS CloudFormation template for all compute resources and create a stack in two Regions.
    Write a script that promotes the Aurora Replica to the primary instance in the event of a failure.
  • B. Use AWS Lambda to create and copy a snapshot of the Aurora DB cluster to the destination Region hourly.
    Create an AWS CloudFormation template that includes an Auto Scaling group, and create a stack in two Regions.
    Restore the Aurora DB cluster from a snapshot and update the Auto Scaling group to start launching instances.
  • C. Launch an Aurora DB cluster as an Aurora Replica in a different Region and configure automatic cross-Region failover.
    Create an AWS CloudFormation template that includes an Auto Scaling group, and create a stack in two Regions.
    Write a script that updates the CloudFormation stack in the disaster recovery Region to increase the number of instances.
  • D. Configure Amazon DynamoDB cross-Region replication.
    Create an AWS CloudFormation template that includes an Auto Scaling group, and create a stack in two Regions.
    Write a script that will update the CloudFormation stack in the disaster recovery Region and promote the DynamoDB replica to the primary instance in the event of a failure.

NEW QUESTION # 477
You work for a company that has multiple applications which are very different and built on different programming languages. How can you deploy applications as quickly as possible?

  • A. Develop each app in one Docker container and deploy using ElasticBeanstalk
  • B. Develop each app in a separate Docker containers and deploy using CloudFormation
  • C. Develop each app in a separate Docker container and deploy using Elastic Beanstalk V
  • D. Create a Lambda function deployment package consisting of code and any dependencies

Answer: C

Explanation:
Explanation
Elastic Beanstalk supports the deployment of web applications from Docker containers. With Docker containers, you can define your own runtime environment. You can choose your own platform, programming language, and any application dependencies (such as package managers or tools), that aren't supported by other platforms. Docker containers are self-contained and include all the configuration information and software your web application requires to run.
Option A is an efficient way to use Docker. The entire idea of Docker is that you have a separate environment for various applications.
Option B is ideally used to running code and not packaging the applications and dependencies Option D is not ideal deploying Docker containers using Cloudformation For more information on Docker and Clastic Beanstalk, please visit the below URL:

NEW QUESTION # 478
You have an ELB setup in AWS with EC2 instances running behind it. You have been requested to monitor
the incoming connections to the ELB. Which of the below options can suffice this requirement?

  • A. UseAWSCIoudTrail with your load balancer
  • B. Create a custom metric CloudWatch filter on your load balancer
  • C. Use a CloudWatch Logs Agent
  • D. Enable access logs on the load balancer

Answer: D

Explanation:
Explanation
Clastic Load Balancing provides access logs that capture detailed information about requests sent to your load
balancer. Cach log contains information such as the
time the request was received, the client's IP address, latencies, request paths, and server responses. You can
use these access logs to analyze traffic patterns and
to troubleshoot issues.
Option A is invalid because this service will monitor all AWS services
Option C and D are invalid since CLB already provides a logging feature.
For more information on ELB access logs, please refer to the below document link: from AWS

NEW QUESTION # 479
You need your API backed by DynamoDB to stay online duringa total regional AWS failure. You can tolerate a couple minutes of lag or slowness during a large failure event, but the system should recover with normal operation after those few minutes. What is a good approach?

  • A. Set up DynamoDB cross-region replication in a master-standby configuration, with a single standby in another region. Create an Auto Scaling Group behind an ELB in each of the two regions for your application layer in which DynamoDB is running in. Add a Route53 Latency DNS Record with DNS Failover, using the ELBs in the two regions as the resource records.
  • B. Set up DynamoDB cross-region replication in a master-standby configuration, with a single standby in another region. Create a crossregion ELB pointing to a cross-region Auto Scaling Group, and direct a Route53 Latency DNS Record with DNS Failover to the cross- region ELB.
  • C. Set up a DynamoDB Global table. Create an Auto Scaling Group behind an ELB in each of the two regions for your application layer in which the DynamoDB is running in. Add a Route53 Latency DNS Record with DNS Failover, using the ELBs in the two regions as the resource records.
  • D. Set up a DynamoDB Multi-Region table. Create a cross-region ELB pointing to a cross-region Auto Scaling Group, and direct a Route53 Latency DNS Record with DNS Failover to the cross-region ELB.

Answer: C

Explanation:
Explanation
Updated based on latest AWS updates
Option A is invalid because using Latency based routing will sent traffic on the region with the standby instance. This is an active/passive replication and you can't write to the standby table unless there is a failover. Answer A can wort: only if you use a failover routing policy.
Option D is invalid because there is no concept of a cross region CLB.
Amazon DynamoDBglobal tables provide a fully managed solution for deploying a multi-region, multi-master database, without having to build and maintain your own replication solution. When you create a global table, you specify the AWS regions where you want the table to be available. DynamoDB performs all of the necessary tasks to create identical tables in these regions, and propagate ongoing data changes to all of them.
