A developer needs to implement a custom machine learning (ML) library in an application. The size of the library is 15 GB. The size of the library is increasing. The application uses AWS Lambda functions. All the Lambda functions must have access to the library.
Which solution will meet these requirements?
A. Save the library in Lambda layers. Attach the layers to all Lambda functions.A social media company is designing a platform that allows users to upload data, which is stored in Amazon S3. Users can upload data encrypted with a public key. The company wants to ensure that only the company can decrypt the uploaded content by using an asymmetric encryption key. The data must always be encrypted both in transit and at rest.
Which solution will meet these requirements?
A. Use server-side encryption with Amazon S3 managed keys (SSE-S3) to encrypt the data.A developer is setting up a deployment pipeline. The pipeline includes an AWS CodeBuild build stage that requires access to a database to run integration tests. The developer is using a buildspec.yml file to configure the database connection. Company policy requires automatic rotation of all database credentials.
Which solution will handle the database credentials MOST securely?
A. Retrieve the credentials from variables that are hardcoded in the buildspec.yml file. Configure an AWS Lambda function to rotate the credentials.A company is developing an ecommerce application that uses Amazon API Gateway APIs. The application uses AWS Lambda as a backend. The company needs to test the code in a dedicated, monitored test environment before the company releases the code to the production environment.
Which solution will meet these requirements?
A. Use a single stage in API Gateway. Create a Lambda function for each environment. Configure API clients to send a query parameter that indicates the environment and the specific Lambda function.A developer is deploying a new application to Amazon Elastic Container Service (Amazon ECS). The developer needs to securely store and retrieve different types of variables. These variables include authentication information for a remote API, the URL for the API, and credentials. The authentication information and API URL must be available to all current and future deployed versions of the application across development, testing, and production environments.
How should the developer retrieve the variables with the FEWEST application changes?
A. Update the application to retrieve the variables from AWS Systems Manager Parameter Store. Use unique paths in Parameter Store for each variable in each environment. Store the credentials in AWS Secrets Manager in each environment.A developer previously deployed an AWS Lambda function as a .zip package. The developer now needs to redeploy the Lambda function as a container image.
Which solution will meet this requirement?
A. Create an Amazon ECR repository in the same AWS Region as the Lambda function. Package the Lambda function into a container image. Build the image and upload it to the Amazon ECR repository. Update the existing Lambda function configuration to specify the repository URI and container image tag.A developer migrated a legacy application to an AWS Lambda function. The function uses a third-party service to pull data with a series of API calls at the end of each month. The function then processes the data to generate the monthly reports. The function has been working with no issues so far.
The third-party service recently issued a restriction to allow a fixed number of API calls each minute and each day. If the API calls exceed the limit for each minute or each day, then the service will produce errors. The API also provides the minute limit and daily limit in the response header. This restriction might extend the overall process to multiple days because the process is consuming more API calls than the available limit.
What is the MOST operationally efficient way to refactor the serverless application to accommodate this change?
A. Use an AWS Step Functions state machine to monitor API failures. Use the Wait state to delay calling the Lambda function.An organization is storing large files in Amazon S3, and is writing a web application to display meta-data about the files to end-users. Based on the metadata a user selects an object to download. The organization needs a mechanism to index the files and provide single-digit millisecond latency retrieval for the metadata.
What AWS service should be used to accomplish this?
A. Amazon DynamoDBAn application ingests data from an Amazon Kinesis data stream. The shards in the data stream are configured for normal traffic.
During peak traffic testing, the application ingests data slowly. A developer needs to adjust the data stream to handle peak traffic.
What is the MOST cost-effective action the developer should take to meet this requirement?
A. Install the Kinesis Producer Library (KPL) to ingest data into the data stream.A company has a mobile app. The app includes an Amazon API Gateway REST API that invokes AWS Lambda functions. The Lambda functions process data from the app.
The company needs to test updated Lambda functions that have new features. The company must conduct these tests with a subset of users before deployment. The tests must not affect other users of the app.
Which solution will meet these requirements with the LEAST amount of operational effort?
A. Create a new version of each Lambda function with a weighted alias. Configure a weight value for each version of the Lambda function. Update the new weighted alias Amazon Resource Name (ARN) in the REST API.Nowadays, the certification exams become more and more important and required by more and more enterprises when applying for a job.
