Question #161 / 1019

A company has a Python application that processes CSV files and stores the results in an on-premises MySQL database. The application runs several thousand times daily. The company wants to migrate the application to AWS Cloud, requiring a highly available solution that ensures maximum scalability and minimal operational overhead.

Which solution meets these requirements?

A

Store the CSV files in an Amazon S3 bucket. Deploy the Python code on multiple Amazon EC2 instances to process the files. Save the results in an Amazon Aurora DB cluster.

B

Store the CSV files in an Amazon S3 bucket. Configure an AWS Lambda function to execute the Python code and process the files upon upload to the S3 bucket. Save the results in an Amazon Aurora DB cluster.

C

Store the CSV files on an Amazon EBS volume with Multi-Attach enabled. Attach the volume to multiple EC2 instances running the Python code. Save the results in an Amazon RDS MySQL DB instance.

D

Upload the CSV files as messages to an Amazon SQS queue. Deploy the Python code in containers on an Amazon ECS cluster using the EC2 launch type. Process the messages and save the results in an Amazon RDS MySQL DB instance.

Question #744 / 1019

A company is deploying a REST API on Amazon EC2 instances behind an Elastic Load Balancing (ELB) load balancer. Legacy client systems require traffic to originate from a fixed IP address for firewall permissions. What should the solutions architect implement to satisfy this requirement?

A

A Network Load Balancer with an associated Elastic IP address.

B

An Application Load Balancer with an associated Elastic IP address.

C

An A record in an Amazon Route 53 hosted zone pointing to an Elastic IP address.

D

An EC2 instance with a public IP address running as a proxy in front of the load balancer.

Sample Questions

Question #264 / 529

A company has deployed a web application on Amazon EC2 instances across three Availability Zones within a VPC. The instances are in private subnets and are part of an Auto Scaling group behind an Application Load Balancer (ALB). The application must communicate with an on-premises database that only allows incoming connections from a specific Elastic IP address. The company's security team has allocated this Elastic IP and added it to the on-premises firewall's allow list. The solutions architect must design a solution that ensures all outbound traffic to the on-premises database originates from the allocated Elastic IP and automatically recovers from any infrastructure failures. Which solution meets these requirements?

A

Deploy three NAT gateways, one in each public subnet. Assign the Elastic IP address to all NAT gateways. Configure health checks for the NAT gateways. If a NAT gateway fails, automatically recreate it and reattach the Elastic IP address.

B

Replace the ALB with a Network Load Balancer (NLB). Assign the Elastic IP address to the NLB. Enable health checks for the NLB. If a health check fails, redeploy the NLB in a different subnet.

C

Deploy a single NAT gateway in a public subnet. Assign the Elastic IP address to the NAT gateway. Use Amazon CloudWatch to monitor the NAT gateway's health. If it becomes unhealthy, trigger an AWS Lambda function to create a new NAT gateway in another subnet and associate the Elastic IP address.

D

Assign the Elastic IP address to the ALB. Configure an Amazon Route 53 health check for the ALB. If the health check fails, redeploy the ALB in a different subnet and update the Route 53 record.

Question #315 / 529

A company operates a data analytics platform in an AWS Region located in the United States. The platform utilizes an Amazon API Gateway Regional API and AWS Lambda functions to process real-time analytics from an Amazon RDS for PostgreSQL database. The frontend is hosted on Amazon S3 and delivered via an Amazon CloudFront distribution. Amazon Route 53 is employed as the DNS service with a simple routing policy directing traffic to the API Gateway.

The company plans to expand into Asia within six months, where over 85% of the database operations are read-only. They have already deployed the API Gateway and Lambda functions in the new Region.

A solutions architect must design a solution to reduce latency for users accessing analytics reports.

Which solution meets these requirements?

A

Use AWS DMS with full load to replicate the database to the new Region. Switch Route 53 to geolocation routing.

B

Use AWS DMS with full load plus CDC to replicate the database to the new Region. Switch Route 53 to latency-based routing.

C

Configure a cross-Region read replica for the RDS database in the new Region. Change the Route 53 record to latency-based routing to connect to the API Gateway API.

D

Configure a cross-Region read replica for the RDS database in the new Region. Change the Route 53 record to geolocation routing to connect to the API Gateway API.

Sample Questions

Question #506 / 557

A developer is configuring an AWS Lambda function to test a new version alongside the existing production version. The Lambda function uses version aliases to manage deployments across environments. The developer needs to route a percentage of incoming traffic to the new version while keeping the majority on the production version during testing.

Which solution will meet these requirements?

A

Create a weighted alias that distributes traffic between the production version and the new version of the function.

B

Deploy an Application Load Balancer and register both the production version and new version as target groups.

C

Use AWS Step Functions to orchestrate invocations to both versions of the Lambda function.

D

Apply a resource-based policy to the Lambda function allowing access to both versions.

Question #398 / 557

A company that operates a large logistics platform uses an Amazon DynamoDB table to track order data. The company enabled Amazon DynamoDB Streams on the table. The status of each order is stored in an OrderStatus attribute, which can be delayed, shipped, or delivered. The company wants to be notified of delayed orders where the Weight attribute exceeds a specific threshold. A developer must implement a solution to trigger these notifications with minimal development effort. Which approach meets these requirements?

A

Create an event source mapping between DynamoDB Streams and an AWS Lambda function. Use Lambda event filtering to trigger the Lambda function only when OrderStatus is 'delayed' and Weight exceeds the threshold. Configure the Lambda function to send notifications via an Amazon SNS topic.

B

Create an event source mapping between DynamoDB Streams and an AWS Lambda function. Implement logic in the Lambda handler to check if OrderStatus is 'delayed' and Weight exceeds the threshold, then publish to an Amazon SNS topic.

C

Create an Amazon CloudWatch alarm to monitor DynamoDB Streams for delayed orders. Configure the alarm to trigger an Amazon SNS topic when the Weight attribute exceeds the specified threshold.

D

Create an event source mapping between DynamoDB Streams and an Amazon SNS topic. Use event filtering to publish notifications only for delayed orders where Weight exceeds the threshold.
