An application uses Lambda functions to extract metadata from files uploaded to an S3 bucket; the metadata is stored in Amazon DynamoDB. The application starts behaving unexpectedly, and the Developer wants to examine the logs of the Lambda function code for errors.
Based on this system configuration, where would the Developer find the logs?

• A.AWS CloudTrail
• B.Amazon CloudWatch
• C.Amazon S3
• D.Amazon DynamoDB

A company is using Amazon API Gateway to manage access to a set of microservices implemented as AWS
Lambda functions. Following a bug report, the company makes a minor breaking change to one of the APIs.
In order to avoid impacting existing clients when the new API is deployed, the company wants to allow clients six months to migrate from v1 to v2.
Which approach should the Developer use to handle this change?

• A.Use API Gateway to deploy a new stage named v2 to the API and provide users with its URL.
• B.Use API Gateway to automatically propagate the change to clients, specifying 180 days in the phased deployment parameter.
• C.Update the underlying Lambda function, create an Amazon CloudFront distribution with the updated Lambda function as its origin.
• D.Update the underlying Lambda function and provide clients with the new Lambda invocation URL.

A Development team is working on a case management solution that allows medical claims to be processed and reviewed. Users log in to provide information related to their medical and financial situations.
As part of the application, sensitive documents such as medical records, medical imaging, bank statements, and receipts are uploaded to Amazon S3. All documents must be securely transmitted and stored. All access to the documents must be recorded for auditing.
What is the MOST secure approach?

• A.Use S3 default encryption using Advanced Encryption Standard-256 (AES-256) on the destination bucket.
• B.Use Amazon Cognito for authorization and authentication to ensure the security of the application and documents.
• C.Use AWS Lambda to encrypt and decrypt objects as they are placed into the S3 bucket.
• D.Use client-side encryption/decryption with Amazon S3 and AWS KMS.

• B.AWS SNS with AWS SQS
• C.Amazon Elastic MapReduce
• D.AWS Step Functions
