A company is providing weather data over a REST-based API to several customers. The API is hosted by Amazon API Gateway and is integrated with different AWS Lambda functions for each API operation. The company uses Amazon Route 53 for DNS and has created a resource record of weather.example.com. The company stores data for the API in Amazon DynamoDB tables. The company needs a solution that will give the API the ability to fail over to a different AWS Region.
Which solution will meet these requirements?

A.
Deploy a new set of Lambda functions in a new Region. Update the API Gateway API to use an edge-optimized API endpoint with Lambda functions from both Regions as targets. Convert the DynamoDB tables to global tables.
B.
Deploy a new API Gateway API and Lambda functions in another Region. Change the Route 53 DNS record to a multivalue answer. Add both API Gateway APIs to the answer. Enable target health monitoring. Convert the DynamoDB tables to global tables.
C.
Deploy a new API Gateway API and Lambda functions in another Region. Change the Route 53 DNS record to a failover record. Enable target health monitoring. Convert the DynamoDB tables to global tables.
D.
Deploy a new API Gateway API in a new Region. Change the Lambda functions to global functions. Change the Route 53 DNS record to a multivalue answer. Add both API Gateway APIs to the answer. Enable target health monitoring. Convert the DynamoDB tables to global tables.

A company's DevOps engineer is creating an AWS Lambda function to process notifications from an Amazon Simple Notification Service (Amazon SNS) topic. The Lambda function will process the notification messages and will write the contents of the notification messages to an Amazon RDS Multi-AZ DB instance.

During testing, a database administrator accidentally shut down the DB instance. While the database was down the company lost several of the SNS notification messages that were delivered during that time.

The DevOps engineer needs to prevent the loss of notification messages in the future.

Which solutions will meet this requirement? (Choose two.)

A.
Replace the RDS Multi-AZ DB instance with an Amazon DynamoDB table.
B.
Configure an Amazon Simple Queue Service (Amazon SQS) queue as a destination of the Lambda function.
C.
Configure an Amazon Simple Queue Service (Amazon SQS) dead-letter queue for the SNS topic.
D.
Subscribe an Amazon Simple Queue Service (Amazon SQS) queue to the SNS topic. Configure the Lambda function to process messages from the SQS queue.
E.
Replace the SNS topic with an Amazon EventBridge event bus. Configure an EventBridge rule on the new event bus to invoke the Lambda function for each event.

A company has a Java application that uses Amazon Simple Queue Service (Amazon SQS) to parse messages. The application cannot parse messages that are larger than 256 KB in size. The company wants to implement a solution to give the application the ability to parse messages as large as 50 MB.

Which solution will meet these requirements with the FEWEST changes to the code?

A.
Use the Amazon SQS Extended Client Library for Java to host messages that are larger than 256 KB in Amazon S3.
B.
Use Amazon EventBridge to post large messages from the application instead of Amazon SQS.
C.
Change the limit in Amazon SQS to handle messages that are larger than 256 KB.
D.
Store messages that are larger than 256 KB in Amazon Elastic File System (Amazon EFS). Configure Amazon SQS to reference this location in the messages.

A company has two AWS accounts: Account A and Account B. Each account has a VPC. An application that runs in the VPC in Account A needs to write to an Amazon S3 bucket in Account B. The application in Account A already has permission to write to the S3 bucket in Account B.

The application and the S3 bucket are in the same AWS Region. The company cannot send network traffic over the public internet.

Which solution will meet these requirements?

A.
In both accounts, create a transit gateway and VPC attachments in a subnet in each Availability Zone. Update the VPC route tables.
B.
Deploy a software VPN appliance in Account A. Create a VPN connection between the software VPN appliance and a virtual private gateway in Account B.
C.
Create a VPC peering connection between the VPC in Account A and the VPC in Account B. Update the VPC route tables, network ACLs, and security groups to allow network traffic between the peered IP ranges
D.
In Account A, create a gateway VPC endpoint for Amazon S3. Update the VPC route table in Account A.
