Amazon AWS Certified Developer - Associate 認定 DVA-C02 試験問題 (Q57-Q62):

質問 # 57
A company requires that all applications running on Amazon EC2 use IAM roles to gain access to AWS services. A developer is modifying an application that currently relies on IAM user access keys stored in environment variables to access Amazon DynamoDB tables using boto, the AWS SDK for Python.
The developer associated a role with the same permissions as the IAM user to the EC2 instance, then deleted the IAM user. When the application was restarted, the AWS AccessDeniedException messages started appearing in the application logs. The developer was able to use their personal account on the server to run DynamoDB API commands using the AWS CLI.
What is the MOST likely cause of the exception?

A. IAM policies might take a few minutes to propagate to resources.
B. The AWS SDK does not support credentials obtained using an instance role.
C. The instance's security group does not allow access to http://169.254.169.254.
D. Disabled environment variable credentials are still being used by the application.

正解：D

質問 # 58
A developer is building a web application that uses Amazon API Gateway to expose an AWS Lambda function to process requests from clients. During testing, the developer notices that the API Gateway times out even though the Lambda function finishes under the set time limit.
Which of the following API Gateway metrics in Amazon CloudWatch can help the developer troubleshoot the issue? (Choose two.)

A. Latency
B. Count
C. CacheMissCount
D. IntegrationLatency
E. CacheHitCount

正解：A、D

解説：
Amazon API Gateway is a service that enables developers to create, publish, maintain, monitor, and secure APIs at any scale. Amazon CloudWatch is a service that monitors AWS resources and applications. API Gateway provides several CloudWatch metrics to help developers troubleshoot issues with their APIs. Two of the metrics that can help the developer troubleshoot the issue of API Gateway timing out are:
IntegrationLatency: This metric measures the time between when API Gateway relays a request to the backend and when it receives a response from the backend. A high value for this metric indicates that the backend is taking too long to respond and may cause API Gateway to time out.
Latency: This metric measures the time between when API Gateway receives a request from a client and when it returns a response to the client. A high value for this metric indicates that either the integration latency is high or API Gateway is taking too long to process the request or response.

質問 # 59
A company runs an application on AWS. The application stores data in an Amazon DynamoDB table. Some queries are taking a long time to run. These slow queries involve an attribute that is not the table's partition key or sort key.
The amount of data that the application stores in the DynamoDB table is expected to increase significantly. A developer must increase the performance of the queries.
Which solution will meet these requirements?

A. Increase the page size for each request by setting the Limit parameter to be higher than the default value. Configure the application to retry any request that exceeds the provisioned throughput.
B. Turn on read capacity auto scaling for the DynamoDB table. Increase the maximum read capacity units (RCUs).
C. Create a global secondary index (GSI). Set query attribute to be the partition key of the index.
D. Perform a parallel scan operation by issuing individual scan requests. In the parameters, specify the segment for the scan requests and the total number of segments for the parallel scan.

正解：D

質問 # 60
When using the AWS Encryption SDK how does the developer keep track of the data encryption keys used to encrypt data?

A. The data encryption key is stored m the user data for the EC2 instance.
B. The SDK stores the data encryption keys automaticity in Amazon S3.
C. The developer must manually keep Hack of the data encryption keys used for each data object.
D. The SDK encrypts the data encryption key and stores it (encrypted) as part of the resumed ophertext.

正解：D

解説：
Explanation
This solution will meet the requirements by using AWS Encryption SDK, which is a client-side encryption library that enables developers to encrypt and decrypt data using data encryption keys that are protected by AWS Key Management Service (AWS KMS). The SDK encrypts the data encryption key with a customer master key (CMK) that is managed by AWS KMS, and stores it (encrypted) as part of the returned ciphertext.
The developer does not need to keep track of the data encryption keys used to encrypt data, as they are stored with the encrypted data and can be retrieved and decrypted by using AWS KMS when needed. Option A is not optimal because it will require manual tracking of the data encryption keys used for each data object, which is error-prone and inefficient. Option C is not optimal because it will store the data encryption keys automatically in Amazon S3, which is unnecessary and insecure as Amazon S3 is not designed for storing encryption keys. Option D is not optimal because it will store the data encryption key in the user data for the EC2 instance, which is also unnecessary and insecure as user data is not encrypted by default.

質問 # 61
A developer uses AWS CloudFormation to deploy an Amazon API Gateway API and an AWS Step Functions state machine The state machine must reference the API Gateway API after the CloudFormation template is deployed The developer needs a solution that uses the state machine to reference the API Gateway endpoint.
Which solution will meet these requirements MOST cost-effectively?

A. Configure the CloudFormation template to reference the API endpoint in the DefinitionSubstitutions property for the AWS StepFunctions StateMachme resource.
B. Configure the CloudFormation template to store the API endpoint in a standard AWS::AppConfig;:ConfigurationProfile resource Configure the state machine to reference the resource.
C. Configure the CloudFormation template to store the API endpoint in a standard AWS: SecretsManager Secret resource Configure the state machine to reference the resource
D. Configure the CloudFormation template to store the API endpoint in an environment variable for the AWS::StepFunctions::StateMachine resourc Configure the state machine to reference the environment variable

正解：A

解説：
Explanation
The most cost-effective solution is to use the DefinitionSubstitutions property of the AWS::StepFunctions::StateMachine resource to inject the API endpoint as a variable in the state machine definition. This way, the developer can use the intrinsic function Fn::GetAtt to get the API endpoint from the AWS::ApiGateway::RestApi resource, and pass it to the state machine without creating any additional resources or environment variables. The other solutions involve creating and managing extra resources, such as Secrets Manager secrets or AppConfig configuration profiles, which incur additional costs and complexity. References
