Amazon AWS Certified Developer - Associate 認定 DVA-C02 試験問題 (Q296-Q301):

質問 # 296
A company built a new application in the AWS Cloud. The company automated the bootstrapping of new resources with an Auto Scaling group by using AWS CloudFormation templates. The bootstrap scripts contain sensitive data.
The company needs a solution that is integrated with CloudFormation to manage the sensitive data in the bootstrap scripts.
Which solution will meet these requirements in the MOST secure way?

A. Put the sensitive data into AWS Systems Manager Parameter Store as a secure string parameter.
Update the CloudFormation templates to use dynamic references to specify template values.
B. Put the sensitive data into an Amazon S3 bucket. Update the CloudFormation templates to download the object from Amazon S3 during bootstrap.
C. Put the sensitive data into Amazon Elastic File System (Amazon EFS). Enforce EFS encryption after file system creation. Update the CloudFormation templates to retrieve data from Amazon EFS.
D. Put the sensitive data into a CloudFormation parameter. Encrypt the CloudFormation templates by using an AWS Key Management Service (AWS KMS) key.

正解：A

質問 # 297
A developer wants to expand an application to run in multiple AWS Regions. The developer wants to copy Amazon Machine Images (AMIs) with the latest changes and create a new application stack in the destination Region. According to company requirements, all AMIs must be encrypted in all Regions. However, not all the AMIs that the company uses are encrypted.
How can the developer expand the application to run in the destination Region while meeting the encryption requirement?

A. Create new AMIs, and specify encryption parameters. Copy the encrypted AMIs to the destination Region. Delete the unencrypted AMIs.
B. Use AWS Certificate Manager (ACM) to enable encryption on the unencrypted AMIs. Copy the encrypted AMIs to the destination Region.
C. Copy the unencrypted AMIs to the destination Region. Enable encryption by default in the destination Region.
D. Use AWS Key Management Service (AWS KMS) to enable encryption on the unencrypted AMIs. Copy the encrypted AMIs to the destination Region.

正解：D

質問 # 298
A developer wants to deploy a new version of an AWS Elastic Beanstalk application. During deployment the application must maintain full capacity and avoid service interruption. Additionally, the developer must minimize the cost of additional resources that support the deployment.
Which deployment method should the developer use to meet these requirements?

A. Bluegreen
B. Immutable
C. All at once
D. Rolling with additional batch

正解：D

解説：
This solution will meet the requirements by using a rolling with additional batch deployment method, which deploys the new version of the application to a separate group of instances and then shifts traffic to those instances in batches. This way, the application maintains full capacity and avoids service interruption during deployment, as well as minimizes the cost of additional resources that support the deployment. Option A is not optimal because it will use an all at once deployment method, which deploys the new version of the application to all instances simultaneously, which may cause service interruption or downtime during deployment. Option C is not optimal because it will use a blue/green deployment method, which deploys the new version of the application to a separate environment and then swaps URLs with the original environment, which may incur more costs for additional resources that support the deployment. Option D is not optimal because it will use an immutable deployment method, which deploys the new version of the application to a fresh group of instances and then redirects traffic to those instances, which may also incur more costs for additional resources that support the deployment.

質問 # 299
A developer needs to use Amazon DynamoDB to store customer orders. The developer's company requires all customer data to be encrypted at rest with a key that the company generates. What should the developer do to meet these requirements?

A. Create the DynamoDB table with encryption set to None. Code the application to use the key to decrypt the data when the application reads from the table. Code the application to use the key to encrypt the data when the application writes to the table.
B. Store the key by using AWS KMS. Choose an AWS KMS AWS managed key during creation of the DynamoDB table. Provide the Amazon Resource Name (ARN) of the AWS KMS key.
C. Store the key by using AWS KMS. Create the DynamoDB table with default encryption. Include the kms:Encrypt parameter with the Amazon Resource Name (ARN) of the AWS KMS key when using the DynamoDB SDK.
D. Store the key by using AW5 KMS. Choose an AVVS KMS customer managed key during creation of the DynamoDB table. Provide the Amazon Resource Name (ARN) of the AWS KMS key.

正解：D

質問 # 300
A developer needs approval from a product owner before the developer can deploy code for an application to production. The developer uses AWS CodePipeline to deploy the application. The developer configures an Amazon Simple Notification Service (Amazon SNS) topic to send notifications to the product owner.
Which solution is the MOST operationally efficient way for the developer to receive approval from the product owner?

A. Add a manual approval action to the existing production deployment stage in CodePipeline.
Specify the SNS topic's Amazon Resource Name (ARN) while configuring the new manual approval action.
B. Add a new stage to CodePipeline before the production deployment. Add a manual approval action to the new stage. Add a new notification rule in the pipeline settings. Specify manual approval as the event that initiates the notification. Specify the SNS topic's Amazon Resource Name (ARN) to notify the product owner.
C. Develop an AWS Step Functions state machine that sends a notification to the product owner and accepts an approval. Add a new stage to CodePipeline before the production deployment. Add the state machine as a Step Functions action to the new stage.
D. Edit the settings in CodePipeline. Create a new notification rule. Specify manual approval as the event that initiates the notification. Create a new notification target. Specify the SNS topic to notify the product owner. Save the notification rule.

正解：C
