A company's application runs on Amazon EC2 instances behind an Application Load Balancer (ALB). The instances run in an Amazon EC2 Auto Scaling group across multiple Availability Zones. On the first day of every month at midnight. The application becomes much slower when the month-end financial calcualtion bath runs. This causes the CPU utilization of the EC2 instaces to immediately peak to 100%, which disrupts the application.

What should a solution architect recommend to ensure the application is able to handle the workload and avoid downtime?

A. Configure an Amazon CloudFront distribution in from of the ALB.

B. Configure an EC2 Auto Scaling simple scaling policy based on CPU utilization.

C. Configure an EC2 Auto Scaling scheduled scaling policy based on the monthly schedule.

D. Configure Amazon ElasticCache to remove some of the workload from tha EC2 instances.

A company has two VPCs named Management and Production. The Management VPC uses VPNs through a customer gateway to connect to a single device in the data center. The Production VPC uses a virtual private gateway with two attached AWS Direct Connect connections. The Management and Production VPCs both use a single VPC peering connection to allow communication between the applications.

What should a solutions architect do to mitigate any single point of failure in this architecture?

A. Add a set of VPNs between the Management and Production VPCs.

B. Add a second virtual private gateway and attach it to the Management VPC.

C. Add a second set of VPNs to the Management VPC from a second customer gateway device.

D. Add a second VPC peering connection between the Management VPC and the Production VPC.

The users must be able to reply to the SMS messages. The company must store the responses for a year for analysis.

What should a solutions architect do to meet these requirements?

A. Create an Amazon Connect contact flow to send the SMS messages. Use AWS Lambda to process the responses.

B. Build an Amazon Pinpoint journey. Configure Amazon Pinpoint to send events to an Amazon Kinesis data stream for analysis and archiving.

C. Use Amazon Simple Queue Service (Amazon SQS) to distribute the SMS messages. Use AWS Lambda to process the responses.

D. Create an Amazon Simple Notification Service (Amazon SNS) FIFO topic. Subscribe an Amazon Kinesis data stream to the SNS topic for analysis and archiving.

A company wants to migrate an Oracle database to AWS. The database consists of a single table that contains millions of geographic information systems (GIS) images that are high resolution and are identified by a geographic code.

When a natural disaster occurs tens of thousands of images get updated every few minutes. Each geographic code has a single image or row that is associated with it. The company wants a solution that is highly available and scalable during such events Which solution meets these requirements MOST cost-effectively?

A. Store the images and geographic codes in a database table. Use Oracle running on an Amazon RDS Multi-AZ DB instance.

B. Store the images in Amazon S3 buckets. Use Amazon DynamoDB with the geographic code as the key and the image S3 URL as the value.

C. Store the images and geographic codes in an Amazon DynamoDB table. Configure DynamoDB Accelerator (DAX) during times of high load.

D. Store the images in Amazon S3 buckets. Store geographic codes and image S3 URLs in a database table. Use Oracle running on an Amazon RDS Multi-AZ DB instance.

An ecommerce company is experiencing an increase in user traffic. The company's store is deployed on Amazon EC2 instances as a two-tier web application consisting of a web tier and a separate database tier. As traffic increases, the

company notices that the architecture is causing significant delays in sending timely marketing and order confirmation email to users. The company wants to reduce the time it spends resolving complex email delivery issues and minimize

operational overhead.

What should a solutions architect do to meet these requirements?

A. Create a separate application tier using EC2 instances dedicated to email processing.

B. Configure the web instance to send email through Amazon Simple Email Service (Amazon SES).

C. Configure the web instance to send email through Amazon Simple Notification Service (Amazon SNS)

D. Create a separate application tier using EC2 instances dedicated to email processing. Place the instances in an Auto Scaling group.

A company has resources across multiple AWS Regions and accounts. A newly hired solutions architect discovers a previous employee did not provide details about the resources invent^. The solutions architect needs to build and map the relationship details of the various workloads across all accounts.

Which solution will meet these requirements in the MOST operationally efficient way?

A. Use AWS Systems Manager Inventory to generate a map view from the detailed view report.

B. Use AWS Step Functions to collect workload details Build architecture diagrams of the workloads manually.

C. Use Workload Discovery on AWS to generate architecture diagrams of the workloads.

D. Use AWS X-Ray to view the workload details Build architecture diagrams with relationships

A company hosts multiple applications on AWS for different product lines. The applications use different compute resources, including Amazon EC2 instances and Application Load Balancers. The applications run in different AWS accounts

under the same organization in AWS Organizations across multiple AWS Regions. Teams for each product line have tagged each compute resource in the individual accounts.

The company wants more details about the cost for each product line from the consolidated billing feature in Organizations.

Which combination of steps will meet these requirements? (Choose two.)

A. Select a specific AWS generated tag in the AWS Billing console.

B. Select a specific user-defined tag in the AWS Billing console.

C. Select a specific user-defined tag in the AWS Resource Groups console.

D. Activate the selected tag from each AWS account.

E. Activate the selected tag from the Organizations management account.

A company has an on-premises SFTP file transfer solution. The company is migrating to the AWS Cloud to scale the file transfer solution and to optimize costs by using Amazon S3. The company's employees will use their credentials for the on-premises Microsoft Active Directory (AD) to access the new solution. The company wants to keep the current authentication and file access mechanisms.

Which solution will meet these requirements with the LEAST operational overhead?

A. Configure an S3 File Gateway. Create SMB file shares on the file gateway that use the existing Active Directory to authenticate.
