Amazon AWS Certified Developer - Associate 認定 DVA-C02 試験問題 (Q626-Q631):

質問 # 626
A developer maintains a critical business application that uses Amazon DynamoDB as the primary data store The DynamoDB table contains millions of documents and receives 30-60 requests each minute The developer needs to perform processing in near-real time on the documents when they are added or updated in the DynamoDB table How can the developer implement this feature with the LEAST amount of change to the existing application code?

A. Set up a cron job on an Amazon EC2 instance Run a script every hour to query the table for changes and process the documents
B. Update the application to synchronously process the documents directly after the DynamoDB write
C. Enable a DynamoDB stream on the table Invoke an AWS Lambda function to process the documents.
D. Update the application to send a PutEvents request to Amazon EventBridge. Create an EventBridge rule to invoke an AWS Lambda function to process the documents.

正解：C

解説：
* DynamoDB Streams: Capture near real-time changes to DynamoDB tables, triggering downstream actions.
* Lambda for Processing: Lambda functions provide a serverless way to execute code in response to events like DynamoDB Stream updates.
* Minimal Code Changes: This solution requires the least modifications to the existing application.

質問 # 627
A developer needs to build an AWS CloudFormation template that self-populates the AWS Region variable that deploys the CloudFormation template What is the MOST operationally efficient way to determine the Region in which the template is being deployed?

A. Find the Region from the AWS::Stackld pseudo parameter by using the Fn::Split intrinsic function
B. Require the Region as a CloudFormation parameter
C. Use the AWS:.Region pseudo parameter
D. Dynamically import the Region by referencing the relevant parameter in AWS Systems Manager Parameter Store

正解：C

解説：
* Pseudo Parameters: CloudFormation provides pseudo parameters that reference runtime context, including the current AWS Region.
* Operational Efficiency: The AWS::Region pseudo parameter offers the most direct and self-contained way to obtain the Region dynamically within the template.

質問 # 628
A developer has written the following IAM policy to provide access to an Amazon S3 bucket:

Which access does the policy allow regarding the s3:GetObject and s3:PutObject actions?

A. Access on all buckets that start with "DOC-EXAMPLE-BUCKET" except the "DOC-EXAMPLE- BUCKET/secrets" bucket
B. Access on all objects in the "DOC-EXAMPLE-BUCKET" bucket along with access to all S3 actions for objects in the "DOC-EXAMPLE-BUCKET" bucket that start with "secrets"
C. Access on all objects in the "DOC-EXAMPLE-BUCKET" bucket except on objects that start with
"secrets"
D. Access on all buckets except the "DOC-EXAMPLE-BUCKET" bucket

正解：C

解説：
The IAM policy shown in the image is a resource-based policy that grants or denies access to an S3 bucket based on certain conditions. The first statement allows access to any S3 action on any object in the "DOC- EXAMPLE-BUCKET" bucket when the request is made over HTTPS (the value of aws:SecureTransport is true). The second statement denies access to the s3:GetObject and s3:PutObject actions on any object in the
"DOC-EXAMPLE-BUCKET/secrets" prefix when the request is made over HTTP (the value of aws:
SecureTransport is false). Therefore, the policy allows access on all objects in the "DOC-EXAMPLE- BUCKET" bucket except on objects that start with "secrets". Reference: Using IAM policies for Amazon S3

質問 # 629
A developer uses AWS IAM Identity Center (AWS Single Sign-On) to interact with the AWS CLI and AWS SDKs on a local workstation. API calls to AWS services were working when the SSO access was first configured. However, the developer is now receiving Access Denied errors. The developer has not changed any configuration files or scripts that were previously working on the workstation.
What is the MOST likely cause of the developer's access issue?

A. The developer is attempting to make API calls to the incorrect AWS account.
B. The credentials from the IAM Identity Center federated role have expired.
C. The permission set that is assumed by IAM Identity Center does not have the necessary permissions to complete the API call.
D. The access permissions to the developer's AWS CLI binary file have changed.

正解：B

質問 # 630
A developer is designing an AWS Lambda function that creates temporary files that are less than
10 MB during invocation. The temporary files will be accessed and modified multiple times during invocation. The developer has no need to save or retrieve these files in the future.
Where should the temporary files be stored?

A. the /tmp directory
B. Amazon Elastic File System (Amazon EFS)
C. Amazon Elastic Block Store (Amazon EBS)
D. Amazon S3

正解：A

解説：
A Lambda function has access to local storage in the /tmp directory. Each execution environment provides between 512 MB and 10,240 MB, in 1-MB increments, of disk space in the /tmp directory.
