A solutions architect is designing a secure, cost-effective, and highly available storage solution for a company’s data. One of the requirements is to ensure that the previous version of a file is preserved and can be retrieved if a modified version is uploaded. Additionally, the company must comply with strict regulatory requirements that mandate data retention in an immutable state for at least 3 years before being moved to an archive. Once archived, the data will only be accessed once a year.

How should the solutions architect build the solution?

• Create an Amazon S3 Standard bucket with object-level versioning enabled and configure a lifecycle rule that transfers files to S3 Glacier Deep Archive after 3 years.
• Create an Amazon S3 Standard bucket and enable S3 Object Lock in governance mode.
• Create an Amazon S3 Standard bucket with S3 Object Lock in compliance mode enabled then configure a lifecycle rule that transfers files to S3 Glacier Deep Archive after 3 years.
• Create a One-Zone-IA bucket with object-level versioning enabled and configure a lifecycle rule that transfers files to Amazon S3 Glacier Deep Archive after 3 years.

A company has a serverless application made up of AWS Amplify, Amazon API Gateway and a Lambda function. The application is connected to an Amazon RDS MySQL database instance inside a private subnet. A Lambda Function URL is also implemented as the dedicated HTTPS endpoint for the function, which has the following value:

https://12june1898pil1pinas.lambda-url.us-west-2.on.aws/

There are times during peak loads when the database throws a “too many connections” error preventing the users from accessing the application.

Which solution could the company take to resolve the issue?

• Increase the concurrency limit of the Lambda function
• Provision an RDS Proxy between the Lambda function and RDS database instance
• Increase the rate limit of API Gateway
• Increase the memory allocation of the Lambda function
