A company runs a serverless application using AWS Lambda that processes orders and writes to an Amazon DynamoDB table. The application occasionally fails when DynamoDB throttles writes. The company wants to make the application more resilient. What should a solutions architect recommend?

Use an Amazon SQS queue to decouple the Lambda function from DynamoDB and configure a dead-letter queue.

Switch the Lambda function to use a VPC and provisioned concurrency.

Increase the Lambda function's memory and timeout.

Enable DynamoDB Accelerator (DAX) for the table.

A company runs a file server on an Amazon EC2 instance with an Amazon EBS volume. The company wants to protect against accidental deletion and corruption of files, and also wants to be able to recover to a specific point in time. What should a solutions architect do to meet these requirements?

Use an EBS Multi-Attach volume.

Enable S3 Versioning on the EBS volume.

Take regular EBS snapshots and copy them to another Region.

A company runs a web application that experiences unpredictable traffic spikes. The application is deployed on EC2 instances in an Auto Scaling group. The company wants to ensure that the application can scale out quickly to handle spikes and scale in to reduce costs. What should a solutions architect recommend?

Use a scheduled scaling policy to add instances during expected peak hours.

Use a step scaling policy based on memory utilization.

Use a simple scaling policy based on CPU utilization with a high threshold.

Use a target tracking scaling policy based on the ALB's RequestCountPerTarget metric.

A company runs a stateful application on a single EC2 instance with an EBS volume. The application is critical and must be highly available. The company is willing to modify the application to be stateless. What should a solutions architect recommend to achieve high availability?

Use Amazon EFS to store the application state and run the application on multiple EC2 instances in an Auto Scaling group across multiple Availability Zones.

Take frequent EBS snapshots and restore them to a new instance in another Availability Zone on failure.

Use an EBS Multi-Attach volume and run the application on two EC2 instances in different Availability Zones.

Place the EC2 instance in an Auto Scaling group with a desired capacity of 1 and use an Application Load Balancer.
