Question 1

An online food company provides an Amazon API Gateway HTTP API 1o receive orders for partners. The API is integrated with an AWS Lambda function. The Lambda function stores the orders in an Amazon DynamoDB table. The company expects to onboard additional partners Some to me panthers require additional Lambda function to receive orders. The company has created an Amazon S3 bucket. The company needs 10 store all orders and updates m the S3 bucket for future analysis How can the developer ensure that an orders and updates are stored to Amazon S3 with the LEAST development effort?

Options :

A : Create a new Lambda function and a new API Gateway API endpoint. Configure the new Lambda function to write to the S3 bucket. Modify the original Lambda function to post updates to the new API endpoint.

B : Use Amazon Kinesis Data Streams to create a new data stream. Modify the Lambda function to publish orders to the data stream. Configure the data stream to write to the S3 bucket.

C : Enable DynamoDB Streams on the DynamoDB table. Create a new Lambda function. Associate the stream’s Amazon Resource Name (ARN) with the Lambda function. Configure the Lambda function to write to the S3 bucket as records appear in the table-s stream.

D : Modify the Lambda function to publish to a new Amazon Simple Notification Service (Amazon SNS) topic as the Lambda function receives orders. Subscribe a new Lambda function to the topic. Configure the new Lambda function to write to the S3 bucket as updates come through the topic.

Answer: C

Question 2

A developer is designing a serverless application for a game in which users register and log in through a web browser The application makes requests on behalf of users to a set of AWS Lambda functions that run behind an Amazon API Gateway HTTP API The developer needs to implement a solution to register and log in users on the application's sign-in page. The solution must minimize operational overhead and must minimize ongoing management of user identities. Which solution will meet these requirements'?

Options :

A : Create Amazon Cognito user pools for external social identity providers. Configure IAM roles for the identity pools.

B : Program the sign-in page to create users' IAM groups with the IAM roles attached to the groups.

C : Create an Amazon RDS for SQL Server DB instance to store the users and manage the permissions to the backend resources in AWS.

D : Configure the sign-in page to register and store the users and their passwords in an Amazon DynamoDB table with an attached IAM policy.

Answer: A

Question 3

A developer is deploying a company's application to Amazon EC2 instances The application generates gigabytes of data files each day The files are rarely accessed but the files must be available to the application's users within minutes of a request during the first year of storage The company must retain the files for 7 years. How can the developer implement the application to meet these requirements MOST cost-effectively?

Options :

A :

Store the files in an Amazon S3 bucket Use the S3 Glacier Instant Retrieval storage class Create an S3 Lifecycle policy to transition the files to the S3 Glacier Deep Archive storage class after 1 year

B :

Store the files in an Amazon S3 bucket. Use the S3 Standard storage class. Create an S3 Lifecycle policy to transition the files to the S3 Glacier Flexible Retrieval storage class after 1 year.

C :

Store the files on an Amazon Elastic Block Store (Amazon EBS) volume Use Amazon Data Lifecycle Manager (Amazon DLM) to create snapshots of the EBS volumes and to store those snapshots in Amazon S3

D :

Store the files on an Amazon Elastic File System (Amazon EFS) mount. Configure EFS lifecycle management to transition the files to the EFS Standard-Infrequent Access (Standard-IA) storage class after 1 year.

Answer: A

Question 4

A company runs multiple microservices that each use their own Amazon DynamoDB table. The “customers” microservice needs data that originates in the “orders” microservice.

What approach represents the SIMPLEST method for the “customers” table to get near real-time updates from the “orders” table?

Options :

A :

Enable DynamoDB streams for the “customers” table, trigger an AWS Lambda function to read records from the stream and write them to the “orders” table

B : Enable Amazon DynamoDB streams on the “orders” table, configure the “customers” microservice to read records from the stream

C : Use Amazon CloudWatch Events to send notifications every time an item is added or modified in the “orders” table

D : Use Amazon Kinesis Firehose to deliver all changes in the “orders” table to the “customers” table

Answer: B

Question 5
