Amazon Web Services SAA-C03 Dumps Questions Answers

This solution meets the requirements with the least operational overhead because it leverages the features of IAM Identity Center and AWS Control Tower to centrally manage multiple user permissions across all the accounts. By creating new groups and permission sets, the company can assign fine-grained permissions to the developer and administrator teams based on their roles and responsibilities. The permission sets are applied to the groups at the organization level, so they are automatically inherited by all the accounts in the organization. When new users are hired, the company only needs to add them to the appropriate group in IAM Identity Center, and they will automatically get the permissions assigned to that group. This simplifies the user management and reduces the manual effort of assigning permissions to each user individually.

The correct solution is to create an Object Lambda Access Point and an AWS Lambda function that redacts the PII when the function reads the file. This way, the company can use the S3 Object Lambda feature to modify the S3 object content on the fly, without creating a copy or changing the originalobject. The external service provider can access the Object Lambda Access Point and get the redacted version of the file. This solution has the least operational overhead because it does not require any additional storage, processing, or synchronization. The solution also scales automatically with the number of customer conversations and the demand from the external service provider. The other options are incorrect because:

Option B is using a batch process on an EC2 instance to read, redact, and write the files to a different S3 bucket. This solution has more operational overhead because it requires managing the EC2 instance, the batch process, and the additional S3 bucket. It also introduces latency and inconsistency between the original and the redacted files.

Option C is using a web application on an EC2 instance to present, redact, and download the files. This solution has more operational overhead because it requires managing the EC2 instance, the web application, and the download process. It also exposes the original files to the web application, which increases the risk of leaking the PII.

Option D is using a DynamoDB table and a Lambda function to store the non-PII data from the files. This solution has more operational overhead because it requires managing the DynamoDB table, the Lambda function, and the data transformation. It also changes the format and the structure of the original files, which may affect the quality control process.

This solution will meet the requirements with the most operational efficiency because:

Amazon Cognito user pools provide a secure and scalable user directory that can store and manage user profiles, and handle user sign-up, sign-in, and access control. User pools can also integrate with social identity providers and enterprise identity providers via SAML or OIDC. User pools can issue JSON Web Tokens (JWTs) that can be used to authenticate users and authorize API requests.

Amazon API Gateway REST APIs enable you to create and deploy APIs that expose your backend services to your clients. REST APIs support multiple authorization mechanisms, including Cognito user pools, IAM, Lambda, and custom authorizers. A Cognito authorizer is a type of Lambda authorizer that uses a Cognito user pool as the identity source. When a client makes a request to a REST API method that is configured with a Cognito authorizer, API Gateway verifies the JWTs that are issued by the user pool and grants access based on the token’s claims and the authorizer’s configuration.

By using Cognito user pools and API Gateway REST APIs with a Cognito authorizer, you can achieve a high level of security, scalability, and performance for your web analytics service. You can also leverage the built-in features of Cognito and API Gateway, such as user management, token validation, caching, throttling, and monitoring, without having to implement them yourself. This reduces the operational overhead and complexity of your solution.
