                                問題 #710
                                A company hosts its application in the us-west-1 Region. The company wants to add redundancy in the us- east-1 Region. The application secrets are stored in AWS Secrets Manager in us-west-1. A developer needs to replicate the secrets to us-east-1.
                                Which solution will meet this requirement?

                                答案：C

                                解題說明：
                                AWS Secrets Manager supports multi-Region secret replication, which is designed specifically for redundancy, disaster recovery, and multi-Region applications. With this feature, the primary secret resides in one Region (here, us-west-1) and Secrets Manager automatically maintains a replica in another Region (us- east-1). This provides local read access and resilience if one Region is impaired.
                                Option A accurately describes the standard configuration: enable secret replication and add us-east-1 as the replica Region. Because encryption keys are Region-scoped, the replica secret in us-east-1 should be encrypted with a KMS key in us-east-1 (either the default Secrets Manager key for that Region or a customer managed key), satisfying encryption requirements and proper key locality.
                                Option B is incorrect because you don't configure replication "from the destination." Replication is configured on the primary secret, and the replica uses a KMS key in the replica Region, not in the source Region.
                                Option C is not how Secrets Manager replication works. Replication is not only during rotation; it maintains replicas continuously. The "replication rule during rotation" framing is not the standard mechanism.
                                Option D is inappropriate and insecure/operationally complex: exporting secrets to S3 for replication is not the recommended pattern and introduces unnecessary exposure.
                                Therefore, enable Secrets Manager multi-Region replication and encrypt replicas with a KMS key in the destination Region.

                                A company is using Amazon API Gateway to invoke a new AWS Lambda function The company has Lambda function versions in its PROD and DEV environments. In each environment, there is a Lambda function alias pointing to the corresponding Lambda function version API Gateway has one stage that is configured to point at the PROD alias The company wants to configure API Gateway to enable the PROD and DEV Lambda function versions to be simultaneously and distinctly available Which solution will meet these requirements?

                                答案：B

                                解題說明：
                                * API Gateway Stages: Stages in API Gateway represent distinct environments (like PROD and DEV) allowing different configurations.
                                * Stage Variables: Stage variables store environment-specific information, including Lambda function aliases.
                                * Ease of Management: This solution offers a straightforward way to manage different Lambda function versions across environments.

                                問題 #712
                                A company is migrating legacy internal applications to AWS. Leadership wants to rewrite the internal employee directory to use native AWS services. A developer needs to create a solution for storing employee contact details and high-resolution photos for use with the new application.
                                Which solution will enable the search and retrieval of each employee's individual details and high-resolution photos using AWS APIs?

                                答案：A

                                解題說明：
                                Explanation
                                Amazon DynamoDB is a fully managed NoSQL database service that provides fast and consistent performance with seamless scalability. The developer can store each employee's contact information in a DynamoDB table along with the object keys for the photos stored in Amazon S3. Amazon S3 is an object storage service that offers industry-leading scalability, data availability, security, and performance. The developer can use AWS APIs to search and retrieve the employee details and photos from DynamoDB and S3.

                                [Amazon DynamoDB]
                                [Amazon Simple Storage Service (S3)]


                                問題 #713
                                A developer is making changes to a custom application that uses AWS Elastic Beanstalk.
                                Which solutions will update the Elastic Beanstalk environment with the new application version after the developer completes the changes? (Select TWO.)

                                答案：C,D


                                問題 #714
                                A developer accesses AWS CodeCommit over SSH. The SSH keys configured to access AWS CodeCommit are tied to a user with the following permissions:

                                The developer needs to create/delete branches
                                Which specific IAM permissions need to be added based on the principle of least privilege?

                                答案：D

                                解題說明：
                                This solution allows the developer to create and delete branches in AWS CodeCommit by granting the codecommit:CreateBranch and codecommit:DeleteBranch permissions. These are the minimum permissions required for this task, following the principle of least privilege. Option B grants too many permissions, such as codecommit:Put*, which allows the developer to create, update, or delete any resource in CodeCommit. Option C grants too few permissions, such as codecommit:Update*, which does not allow the developer to create or delete branches. Option D grants all permissions, such as codecommit:*, which is not secure or recommended.
