Question 32

A company has a website that displays a daily newsletter. When a user visits the website, an AWS Lambda function processes the browser's request and queries the company's on-premises database to obtain the current newsletter. The newsletters are stored in English. The Lambda function uses the Amazon Translate TranslateText API operation to translate the newsletters, and the translation is displayed to the user.

Due to an increase in popularity, the website's response time has slowed. The database is overloaded. The company cannot change the database and needs a solution that improves the response time of the Lambda function.

Which solution meets these requirements?

Options:

Change to asynchronous Lambda function invocation.

Cache the translated newsletters in the Lambda /tmp directory.

Enable TranslateText API caching.

Change the Lambda function to use parallel processing.

Question 33

A company built a new application in the AWS Cloud. The company automated the bootstrapping of new resources with an Auto Scaling group by using AWS Cloudf-ormation templates. The bootstrap scripts contain sensitive data.

The company needs a solution that is integrated with CloudFormation to manage the sensitive data in the bootstrap scripts.

Which solution will meet these requirements in the MOST secure way?

Options:

Put the sensitive data into a CloudFormation parameter. Encrypt the CloudFormation templates by using an AWS Key Management Service (AWS KMS) key.

Put the sensitive data into an Amazon S3 bucket Update the CloudFormation templates to download the object from Amazon S3 during bootslrap.

Put the sensitive data into AWS Systems Manager Parameter Store as a secure string parameter. Update the CloudFormation templates to use dynamic references to specify template values.

Put the sensitive data into Amazon Elastic File System (Amazon EPS) Enforce EFS encryption after file system creation. Update the CloudFormation templates to retrieve data from Amazon EFS.

Question 34

In a move toward using microservices, a company's management team has asked all development teams to build their services so that API requests depend only on that service's data store. One team is building a Payments service which has its own database; the service needs data that originates in the Accounts database. Both are using Amazon DynamoDB.

What approach will result in the simplest, decoupled, and reliable method to get near-real time updates from the Accounts database?

Options:

Use AWS Glue to perform frequent ETL updates from the Accounts database to the Payments database.

Use Amazon ElastiCache in Payments, with the cache updated by triggers in the Accounts database.

Use Amazon Data Firehose to deliver all changes from the Accounts database to the Payments database.

Use Amazon DynamoDB Streams to deliver all changes from the Accounts database to the Payments database.

Question 35

A company is using an Amazon API Gateway REST API endpoint as a webhook to publish events from an on-premises source control management (SCM) system to Amazon EventBridge. The company has configured an EventBridge rule to listen for the events and to control application deployment in a central AWS account. The company needs to receive the same events across multiple receiver AWS accounts.

How can a developer meet these requirements without changing the configuration of the SCM system?

Options:

Deploy the API Gateway REST API to all the required AWS accounts. Use the same custom domain name for all the gateway endpoints so that a single SCM webhook can be used for all events from all accounts.

Deploy the API Gateway REST API to all the receiver AWS accounts. Create as many SCM webhooks as the number of AWS accounts.

Grant permission to the central AWS account for EventBridge to access the receiver AWS accounts. Add an EventBridge event bus on the receiver AWS accounts as the targets to the existing EventBridge rule.

Convert the API Gateway type from REST API to HTTP API.
