Amazon AWS Certified Developer - Associate 認定 DVA-C02 試験問題 (Q649-Q654):

質問 # 649
A company's developer has deployed an application in AWS by using AWS CloudFormation The CloudFormation stack includes parameters in AWS Systems Manager Parameter Store that the application uses as configuration settings. The application can modify the parameter values When the developer updated the stack to create additional resources with tags, the developer noted that the parameter values were reset and that the values ignored the latest changes made by the application. The developer needs to change the way the company deploys the CloudFormation stack. The developer also needs to avoid resetting the parameter values outside the stack.
Which solution will meet these requirements with the LEAST development effort?

正解：B

解説：

質問 # 650
A developer is investigating an issue for a company. Some requests are passing through an Amazon API Gateway endpoint, but they do not reach the AWS Lambda function that backs the endpoint. The developer finds that a second Lambda function sometimes runs at the maximum concurrency that is allowed for the AWS account. How can the developer address this issue?

正解：C

解説：
If a Lambda function is hitting the account-level maximum concurrency limit, increasing the Lambda concurrency quota via the Service Quotas dashboard allows more concurrent executions, preventing throttling and ensuring requests reach the function.


質問 # 651
A developer is working on an application that uses a microservices architecture. The developer needs to grant an AWS Lambda function access to make calls to an Amazon API Gateway HTTP API. The HTTP API requires authentication. Which solution will meet these requirements?

正解：B

解説：
IAM authorization allows the HTTP API route to authenticate requests by using AWS Signature Version 4. The Lambda function can sign requests with credentials from its execution role, and the role policy can grant permission to invoke the required API Gateway route.


質問 # 652
A developer deployed an application to an Amazon EC2 instance The application needs to know the public IPv4 address of the instance How can the application find this information?

正解：B

解説：
* Instance Metadata Service: EC2 instances have access to an internal metadata service. It provides instance-specific information like instance ID, security groups, and public IP address.
* Accessing Metadata:
* Make an HTTP GET request to the base URL: http://169.254.169.254/latest/meta-data/
* You'll get a list of available categories. The public IPv4 address is under public-ipv4.


質問 # 653
A company has an Amazon S3 bucket that contains sensitive data. The data must be encrypted in transit and at rest. The company encrypts the data in the S3 bucket by using an AWS KMS key. A developer needs to grant several other AWS accounts the permission to use the S3 GetObject operation to retrieve the data from the S3 bucket.
How can the developer enforce that all requests to retrieve the data provide encryption in transit?

正解：C

解説：
"Encryption in transit" for S3 means requiring requests to use HTTPS (TLS) rather than HTTP. AWS provides a standard policy condition key, aws:SecureTransport, that evaluates to true when the request is made over SSL/TLS and false when it is not. To enforce TLS for all cross-account GetObject requests, the most reliable control point is the S3 bucket resource-based policy, because the bucket is the resource being accessed and the bucket owner can enforce conditions regardless of which external account is calling.
Option A is the established pattern: add an explicit Deny statement in the bucket policy that denies all S3 actions (or at least s3:GetObject) when aws:SecureTransport is false. An explicit deny overrides any allows, ensuring that even if another account's IAM policy allows access, the request will still be blocked if it is not using HTTPS.
Option B is backwards because it would allow insecure transport rather than deny it.
Option C is weaker because you cannot reliably enforce policies in other accounts (and principals could change roles or permissions). The bucket owner should enforce transport security at the bucket level.
Option D is not the right layer: the KMS key policy controls key usage, but the S3 GetObject transport requirement is best enforced by the S3 bucket policy. Also, S3 access can be denied before KMS is even involved.
Therefore, enforce HTTPS by adding a bucket policy Deny when aws:SecureTransport is false.
