Amazon AWS Certified DevOps Engineer - Professional 認定 DOP-C01 試験問題 (Q372-Q377):

質問 # 372
You work for a startup that has developed a new photo-sharing application for mobile devices. Over recent months your application has increased in popularity; this has resulted in a decrease in the performance of the application due to the increased load. Your application has a two-tier architecture that is composed of an Auto Scaling PHP application tier and a MySQL RDS instance initially deployed with AWS CloudFormation. Your Auto Scaling group has a min value of 4 and a max value of 8. The desired capacity is now at 8 due to the high CPU utilization of the instances. After some analysis, you are confident that the performance issues stem from a constraint in CPU capacity, while memory utilization remains low. You therefore decide to move from the general-purpose M3 instances to the compute-optimized C3 instances. How would you deploy this change while minimizing any interruption to your end users?

A. Signin to the AWS Management Console, copy the old launch configuration, and createa new launch configuration that specifies the C3 instances. Update the AutoScaling group with the new launch configuration. Auto Scaling will then updatethe instance type of all running instances
B. Updatethe launch configuration specified in the AWS CloudFormation template with thenew C3 instance type. Also add an UpdatePolicy attribute to your Auto Scalinggroup that specifies an AutoScalingRollingUpdate. Run a stack update with thenew template
C. Updatethe launch configuration specified in the AWS CloudFormation template with thenew C3 instance type. Run a stack update with the new template. Auto Scalingwill then update the instances with the new instance type.
D. Signinto the AWS Management Console and update the existing launch configurationwith the new C3 instance type. Add an UpdatePolicy attribute to your AutoScaling group that specifies an AutoScaling RollingUpdate.

正解：B

解説：
Explanation
The AWS Documentation mentions the below
The AWS::AutoScaling::AutoScalingGroup resource supports an UpdatePolicy attribute. This is used to define how an Auto Scaling group 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 Scaling group and replaces old instances with new ones, according to the parameters specified.

質問 # 373
You need to implement A/B deployments for several multi-tier web applications. Each of them has Its Individual infrastructure:
Amazon Elastic Compute Cloud (EC2) front-end servers, Amazon ElastiCache clusters, Amazon Simple Queue Service (SQS) queues, and Amazon Relational Database (RDS) Instances.
Which combination of services would give you the ability to control traffic between different deployed versions of your application? (Choose one.)

A. Create one Elastic Beanstalk application and all AWS resources (using configuration files inside the application source bundle) for each web application.
New versions would be deployed updating the Elastic Beanstalk application version for the current Elastic Beanstalk environment.
B. Using AWS CloudFormation templates, create one Elastic Beanstalk application and all AWS resources (in the same template) for each web application.
New versions would be deployed using AWS CloudFormation templates to create new Elastic Beanstalk environments, and traffic would be balanced between them using weighted Round Robin (WRR) records in Amazon Route53.
C. Create one AWS Elastic Beanstalk application and all AWS resources (using configuration files inside the application source bundle) for each web application.
New versions would be deployed a-eating Elastic Beanstalk environments and using the Swap URLs feature.
D. Using AWS CloudFormation templates, create one Elastic Beanstalk application and all AWS resources (in the same template) for each web application.
New versions would be deployed updating a parameter on the CloudFormation template and passing it to the cfn-hup helper daemon, and traffic would be balanced between them using Weighted Round Robin (WRR) records in Amazon Route 53.

正解：B

質問 # 374
A company runs an application on Amazon EC2 instances behind an Application Load Balancer. The instances run in an Amazon EC2 Auto Scaling group across multiple Availability Zones in us-east1. The application stores data in an Amazon RDS MySQL Multi-AZ DB instance. A DevOps Engineer wants to modify the current solution and create a hot standby of the environment in another region to minimize downtime if a problem occurs in us-east-1. Which combination of steps should the DevOps Engineer take to meet these requirements? (Select THREE.)

A. Extend the current Auto Scaling group to the subnets in the disaster recovery region.
B. Create a new Application Load Balancer and Auto Scaling group in the disaster recovery region.
C. Add a health check to the Amazon Route 53 alias record to evaluate the health of the primary region. Use AWS Lambda, configured with an Amazon CloudWatch Events trigger, to elect the Amazon RDS master in the disaster recovery region.
D. Enable multi-region failover for the RDS configuration for the database instance.
E. Deploy a read replica of the RDS instance in the disaster recovery region.
F. Create an AWS Lambda function to evaluate the health of the primary region. If it fails, modify the Amazon Route 53 record to point at the disaster recovery region and elect the RDS master.

正解：B、C、E

質問 # 375
You are administering a continuous integration application that polls version control for changes and then launches new Amazon EC2 instances for a full suite of build tests. What should you do to ensure the lowest overall cost while being able to run as many tests in parallel as possible?

A. Perform syntax checking on the continuous integration system before launching a new AWS Data Pipeline for coordinating the output of unit, integration, and build tests.
B. Perform all tests on the continuous integration system, using AWS OpsWorks for unit, integration, and build tests.
C. Perform syntax checking on the continuous integration system before launching a new Amazon EC2 instance for build test, unit and integration tests.
D. Perform syntax and build tests on the continuous integration system before launching the new Amazon EC2 instance unit and integration tests.

正解：D

解説：
Explanation
Continuous Integration (CI) is a development practice that requires developers to integrate code into a shared repository several times a day. Each check-in is then verified by an automated build, allowing teams to detect problems early.
Option A and D are invalid because you can do build tests on a CI system and not only Syntax tests. And Syntax tests are normally done during coding time and not during the build time.
Option C is invalid because Opswork is ideally not used for build and integration tests.
For an example of a Continuous integration system, please refer to the Jenkins system via the url below
* https://jenkins.io/

質問 # 376
You have deployed an Elastic Beanstalk application in a new environment and want to save the current state of your environment in a document. You want to be able to restore your environment to the current state later or possibly create a new environment. You also want to make sure you have a restore point. How can you achieve this?

A. Configuration Management Templates
B. Saved Configurations
C. Use CloudFormation templates
D. Saved Templates

正解：B

解説：
Explanation
You can save your environment's configuration as an object in Amazon S3 that can be applied to other environments during environment creation, or applied to a running environment. Saved configurations are YAML formatted templates that define an environment's platform configuration, tier, configuration option settings, and tags.
For more information on Saved Configurations please refer to the below link:
