A solutions architect observes that a nightly batch processing job is automatically scaled up for 1 hour before the desired Amazon EC2 capacity is reached. The peak capacity is the ‘same every night and the batch jobs always start at 1 AM. The solutions architect needs to find a cost-effective solution that will allow for the desired EC2 capacity to be reached quickly and allow the Auto Scaling group to scale down after the batch jobs are complete.
What should the solutions architect do to meet these requirements?

1. A. Increase the minimum capacity for the Auto Scaling group.
2. B. Increase the maximum capacity for the Auto Scaling group.
3. C. Configure scheduled scaling to scale up to the desired compute level.
4. D. Change the scaling policy to add more EC2 instances during each scaling operation.

Correct Answer: C
By configuring scheduled scaling, the solutions architect can set the Auto Scaling group to automatically scale up to the desired compute level at a specific time (IAM) when the batch job starts and then automatically scale down after the job is complete. This will allow the desired EC2 capacity to be reached quickly and also help in reducing the cost.

A company must migrate 20 TB of data from a data center to the AWS Cloud within 30 days. The company's network bandwidth is limited to 15 Mbps and cannot exceed 70% utilization. What should a solutions architect do to meet these requirements?

1. A. Use AWS Snowball.
2. B. Use AWS DataSync.
3. C. Use a secure VPN connection.
4. D. Use Amazon S3 Transfer Acceleration.

Correct Answer: A
AWS Snowball is a secure data transport solution that accelerates moving large amounts of data into and out of the AWS cloud. It can move up to 80 TB of data at a time, and provides a network bandwidth of up to 50 Mbps, so it is well-suited for the task. Additionally, it is secure and easy to use, making it the ideal solution for this migration.

A company wants to run a gaming application on Amazon EC2 instances that are part of an Auto Scaling group in the AWS Cloud. The application will transmit data by using UDP packets. The company wants to ensure that the application can scale out and in as traffic increases and decreases.
What should a solutions architect do to meet these requirements?

1. A. Attach a Network Load Balancer to the Auto Scaling group
2. B. Attach an Application Load Balancer to the Auto Scaling group.
3. C. Deploy an Amazon Route 53 record set with a weighted policy to route traffic appropriately
4. D. Deploy a NAT instance that is configured with port forwarding to the EC2 instances in the Auto Scaling group.

Correct Answer: B

A hospital recently deployed a RESTful API with Amazon API Gateway and AWS Lambda The hospital uses API Gateway and Lambda to upload reports that are in PDF format and JPEG format The hospital needs to modify the Lambda code to identify protected health information (PHI) in the reports
Which solution will meet these requirements with the LEAST operational overhead?

1. A. Use existing Python libraries to extract the text from the reports and to identify the PHI from the extracted text.
2. B. Use Amazon Textract to extract the text from the reports Use Amazon SageMaker to identify the PHI from the extracted text.
3. C. Use Amazon Textract to extract the text from the reports Use Amazon Comprehend Medical to identify the PHI from the extracted text
4. D. Use Amazon Rekognition to extract the text from the reports Use Amazon Comprehend Medical to identify the PHI from the extracted text

Correct Answer: C

A company has a data ingestion workflow that includes the following components:
• An Amazon Simple Notation Service (Amazon SNS) topic that receives notifications about new data deliveries
• An AWS Lambda function that processes and stores the data
The ingestion workflow occasionally fails because of network connectivity issues. When tenure occurs the corresponding data is not ingested unless the company manually reruns the job. What should a solutions architect do to ensure that all notifications are eventually processed?

1. A. Configure the Lambda function (or deployment across multiple Availability Zones
2. B. Modify me Lambda functions configuration to increase the CPU and memory allocations tor the (unction
3. C. Configure the SNS topic's retry strategy to increase both the number of retries and the wait time between retries
4. D. Configure an Amazon Simple Queue Service (Amazon SQS) queue as the on failure destination Modify the Lambda function to process messages in the queue

Correct Answer: A
