An application that runs on AWS receives messages from an Amazon Simple Queue
Service (Amazon SQS) queue and processes the messages in batches. The application sends the data to another SQS queue to be consumed by another legacy application.
The legacy system can take up to 5 minutes to process some transaction data.
A developer wants to ensure that there are no out-of-order updates in the legacy system. The developer cannot alter the behavior of the legacy system.
Which solution will meet these requirements?

  1. Use an SQS FIFO queue. Configure the visibility timeout value.
  2. Use an SQS standard queue with a SendMessageBatchRequestEntry data type.
    Configure the DelaySeconds values.
  3. Use an SQS standard queue with a SendMessageBatchRequestEntry data type.
    Configure the visibility timeout value.
  4. Use an SQS FIFO queue. Configure the DelaySeconds value.

Answer(s): A



A company is building a compute-intensive application that will run on a fleet of
Amazon EC2 instances. The application uses attached Amazon Elastic Block Store
(Amazon EBS) volumes for storing data. The Amazon EBS volumes will be created at time of initial deployment. The application will process sensitive information. All of the data must be encrypted. The solution should not impact the application's performance.
Which solution will meet these requirements?

  1. Configure the fleet of EC2 instances to use encrypted EBS volumes to store data.
  2. Configure the application to write all data to an encrypted Amazon S3
    bucket.
  3. Configure a custom encryption algorithm for the application that will encrypt and decrypt all data.
  4. Configure an Amazon Machine Image (AMI) that has an encrypted root volume and store the data to ephemeral disks.

Answer(s): A



A developer is updating the production version of an AWS Lambda function to fix a defect. The developer has tested the updated code in a test environment. The developer wants to slowly roll out the updates to a small subset of production users before rolling out the changes to all users. Only 10% of the users should be initially exposed to the new code in production.
Which solution will meet these requirements?

  1. Update the Lambda code and create a new version of the Lambda function.
    Create a Lambda function trigger. Configure the traffic weights in the trigger between the two Lambda function versions. Send 90% of the traffic to the production version, and send 10% of the traffic to the new version.
  2. Create a new Lambda function that uses the updated code. Create a Lambda alias for the production Lambda function. Configure the Lambda alias to send
    90% of the traffic to the production Lambda function, and send 10% of the traffic to the test Lambda function.
  3. Update the Lambda code and create a new version of the Lambda function.
    Create a Lambda proxy integration. Configure the Lambda proxy to split traffic between the two Lambda function versions. Send 90% of the traffic to the production version, and send 10% of the traffic to the new version.
  4. Update the Lambda code and create a new version of the Lambda function.
    Create a Lambda function alias. Configure the traffic weights in the Lambda alias between the two Lambda function versions. Send 90% of the traffic to the production version, and send 10% of the traffic to the new version.

Answer(s): D



A developer is creating an AWS Lambda function that consumes messages from an Amazon
Simple Queue Service (Amazon SQS) standard queue. The developer notices that the
Lambda function processes some messages multiple times.
How should developer resolve this issue MOST cost-effectively?

  1. Change the Amazon SQS standard queue to an Amazon SQS FIFO queue by using the Amazon SQS message deduplication ID.
  2. Set up a dead-letter queue.
  3. Set the maximum concurrency limit of the AWS Lambda function to 1.
  4. Change the message processing to use Amazon Kinesis Data Streams instead of
    Amazon SQS.

Answer(s): A
