Amazon AWS Certified Developer - Associate 認定 DVA-C02 試験問題 (Q505-Q510):

質問 # 505
A developer received the following error message during an AWS CloudFormation deployment:
Which action should the developer take to resolve this error?

A. Add a force parameter when calling CloudFormation with the role-am of ASGInstanceRole12345678.
B. Add a DependsOn attribute to the ASGInstanceRole12345678 resource in the CloudFormation template. Then delete the stack.
C. Modify the CloudFormation template to retain the ASGInstanceRolet 2345678 resource. Then manually delete the resource after deployment.
D. Contact AWS Support to report an issue with the Auto Scaling Groups (ASG> service.

正解：C

質問 # 506
A developer is using an AWS Lambda function to generate avatars for profile pictures that are uploaded to an Amazon S3 bucket. The Lambda function is automatically invoked for profile pictures that are saved under the
/original/ S3 prefix. The developer notices that some pictures cause the Lambda function to time out. The developer wants to implement a fallback mechanism by using another Lambda function that resizes the profile picture.
Which solution will meet these requirements with the LEAST development effort?

A. Create an Amazon Simple Notification Service (Amazon SNS) topic. Set the SNS topic as a destination with an on failure condition for the avatar generator Lambda function. Subscribe the image resize Lambda function to the SNS topic.
B. Set the image resize Lambda function as a destination of the avatar generator Lambda function for the events that fail processing.
C. Create an Amazon Simple Queue Service (Amazon SQS) queue. Set the SQS queue as a destination with an on failure condition for the avatar generator Lambda function. Configure the image resize Lambda function to poll from the SQS queue.
D. Create an AWS Step Functions state machine that invokes the avatar generator Lambda function and uses the image resize Lambda function as a fallback. Create an Amazon EventBridge rule that matches events from the S3 bucket to invoke the state machine.

正解：B

解説：
Explanation
The solution that will meet the requirements with the least development effort is to set the image resize Lambda function as a destination of the avatar generator Lambda function for the events that fail processing.
This way, the fallback mechanism is automatically triggered by the Lambda service without requiring any additional components or configuration. The other options involve creating and managing additional resources such as queues, topics, state machines, or rules, which would increase the complexity and cost of the solution.

質問 # 507
A developer is deploying a new application to Amazon Elastic Container Service (Amazon ECS). The developer needs to securely store and retrieve different types of variables. These variables include authentication information for a remote API, the URL for the API, and credentials. The authentication information and API URL must be available to all current and future deployed versions of the application across development, testing, and production environments.
How should the developer retrieve the variables with the FEWEST application changes?

A. Update the application to retrieve the variables from an encrypted file that is stored with the application.
Store the API URL and credentials in unique files for each environment.
B. Update the application to retrieve the variables from AWS Systems Manager Parameter Store. Use unique paths in Parameter Store for each variable in each environment. Store the credentials in AWS Secrets Manager in each environment.
C. Update the application to retrieve the variables from AWS Key Management Service (AWS KMS).
Store the API URL and credentials as unique keys for each environment.
D. Update the application to retrieve the variables from each of the deployed environments. Define the authentication information and API URL in the ECS task definition as unique names during the deployment process.

正解：B

解説：
AWS Systems Manager Parameter Store is a service that provides secure, hierarchical storage for configuration data management and secrets management. The developer can update the application to retrieve the variables from Parameter Store by using the AWS SDK or the AWS CLI. The developer can use unique paths in Parameter Store for each variable in each environment, such as /dev/api-url, /test/api-url, and /prod
/api-url. The developer can also store the credentials in AWS Secrets Manager, which is integrated with Parameter Store and provides additional features such as automatic rotation and encryption.

質問 # 508
A company needs to set up secure database credentials for all its AWS Cloud resources. The company's resources include Amazon RDS DB instances Amazon DocumentDB clusters and Amazon Aurora DB instances. The company's security policy mandates that database credentials be encrypted at rest and rotated at a regular interval.
Which solution will meet these requirements MOST securely?

A. Store the database access credentials as an encrypted Amazon S3 object in an S3 bucket Block all public access on the S3 bucket. Use S3 server-side encryption to set up automatic rotation on the encryption key.
B. Create an AWS Lambda function by using the SecretsManagerRotationTemplate template in the AWS Secrets Manager console. Create secrets for the database credentials in Secrets Manager Set up secrets rotation on a schedule.
C. Create parameters for the database credentials in AWS Systems Manager Parameter Store Set the Type parameter to Secure Sting. Set up automatic rotation on the parameters.
D. Set up IAM database authentication for token-based access. Generate user tokens to provide centralized access to RDS DB instances. Amazon DocumentDB clusters and Aurora DB instances.

正解：B

解説：
This solution will meet the requirements by using AWS Secrets Manager, which is a service that helps protect secrets such as database credentials by encrypting them with AWS Key Management Service (AWS KMS) and enabling automatic rotation of secrets. The developer can create an AWS Lambda function by using the SecretsManagerRotationTemplate template in the AWS Secrets Manager console, which provides a sample code for rotating secrets for RDS DB instances, Amazon DocumentDB clusters, and Amazon Aurora DB instances. The developer can also create secrets for the database credentials in Secrets Manager, which encrypts them at rest and provides secure access to them. The developer can set up secrets rotation on a schedule, which changes the database credentials periodically according to a specified interval or event.
Option A is not optimal because it will set up IAM database authentication for token-based access, which may not be compatible with all database engines and may require additional configuration and management of IAM roles or users. Option B is not optimal because it will create parameters for the database credentials in AWS Systems Manager Parameter Store, which does not support automatic rotation of secrets. Option C is not optimal because it will store the database access credentials as an encrypted Amazon S3 object in an S3 bucket, which may introduce additional costs and complexity for accessing and securing the data.

質問 # 509
A healthcare company discovers that one of the company's AWS Lambda functions is improperly sending customer personal health information (PHI) and personally identifiable information (PII) to an Amazon CloudWatch Logs log group.
The company needs a solution to automatically mask PHI and PII across all log events in the log group. The company must ensure that masked values cannot be accidentally revealed through CloudWatch Logs Insights queries or subscription filters. The solution must allow only specific security engineers to view the original unmasked values when required for investigations.
Which solution will meet these requirements?

A. Update the Lambda function to replace PHI and PII with placeholder character before the function writes logs to the log group.
B. Use Amazon Data Firehose to stream the logs to an Amazon S3 bucket. Use Amazon Athena to query the logs. Use Athena views to filter out PHI and PII.
C. Use AWS KMS to encrypt the log group. Give the security engineers KMS decrypt permissions.
D. Create a CloudWatch Logs data protection policy for the log group. Add a managed data identifier for PHI and PII. Grant the logs:Unmask IAM permission only to security engineers.

正解：D

解説：
CloudWatch Logs data protection policies can automatically detect and mask sensitive data such as PHI and PII in log events. Masked data remains protected in CloudWatch Logs Insights and subscription filters, and only users with the logs:Unmask permission can view the original values when investigation access is required.
