Question #420 / 1019

A company is migrating its production database to AWS and requires an Amazon RDS for PostgreSQL setup that ensures high availability with automatic failover in under 40 seconds. The company also wants to distribute read traffic away from the primary instance while minimizing operational costs.

Which solution meets these requirements?

A

Deploy an Amazon RDS Multi-AZ DB instance with one read replica and direct read workloads to the read replica.

B

Deploy an Amazon RDS Multi-AZ DB cluster with two read replicas and direct read workloads to the read replicas.

C

Deploy an Amazon RDS Multi-AZ DB instance and direct read workloads to the standby instance in the Multi-AZ configuration.

D

Deploy an Amazon RDS Multi-AZ DB cluster and direct read workloads to the cluster's reader endpoint.

Question #184 / 1019

A company uses an AWS account connected to its on-premises data center via two AWS Direct Connect links. All non-VPC traffic is routed through a virtual private gateway. A development team deployed an AWS Lambda function via the console and needs it to access an on-premises file server hosted in a private subnet within the data center. Which solution meets these requirements?

A

Deploy the Lambda function within the VPC using a security group that permits access to the on-premises file server.

B

Establish a VPN connection between AWS and the data center. Route Lambda traffic through the VPN.

C

Assign an Elastic IP to the Lambda function and configure it to route traffic without an elastic network interface.

D

Modify the VPC route tables to enable Lambda traffic to reach the on-premises data center via Direct Connect.

Sample Questions

Question #460 / 529

A company processes video files using a fleet of Amazon EC2 t2.micro instances that pull tasks from an Amazon Simple Queue Service (Amazon SQS) queue. Each task is processed in 10 seconds or less. The instances store the processed videos in an Amazon Elastic File System (Amazon EFS) volume mounted on all instances. Metrics indicate that instances are idle when the SQS queue is empty. A solutions architect must redesign the architecture to optimize costs.

Which combination of steps will meet these requirements MOST cost-effectively? (Choose two.)

A

Use c5.4xlarge instances instead of t2.micro instances for video processing. Reduce the fleet size by 75%.

B

Convert the video processing into an AWS Lambda function. Configure the Lambda function to pull tasks from the SQS queue.

C

Modify the video processing to store results in Amazon DynamoDB.

D

Modify the video processing to store results in Amazon RDS PostgreSQL with auto-scaling enabled.

E

Modify the video processing to store results in Amazon S3.

Question #166 / 529

A retail company operates a serverless e-commerce platform on AWS. The platform's inventory service manages product details in an Amazon DynamoDB table. Several other microservices maintain cached copies of product data in different storage solutions. When a product is discontinued, the inventory service deletes it, and all microservices must immediately remove their cached data to prevent outdated information. Which solution ensures immediate deletion across all services?

A

Enable DynamoDB Streams on the DynamoDB table. Use an AWS Lambda function triggered by the stream to send deletion events to an Amazon Simple Queue Service (Amazon SQS) queue. Configure each microservice to poll the queue and delete the product from the DynamoDB table.

B

Configure DynamoDB event notifications to publish deletion events to an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe each microservice to the SNS topic and delete the product from the DynamoDB table.

C

Have the inventory service publish a custom event to an Amazon EventBridge event bus upon product deletion. Create an EventBridge rule for each microservice to detect the deletion event and trigger their logic to remove cached data.

D

Configure the inventory service to send deletion messages to an Amazon Simple Queue Service (Amazon SQS) queue. Set up each microservice to filter events from the queue and delete the product from the DynamoDB table.

Sample Questions

Question #200 / 557

A company runs a serverless application on AWS using AWS Lambda functions with versions and aliases. They currently deploy updates manually but want to transition to an AWS-native traffic-shifting strategy to gradually roll out new versions to a predefined percentage of users. Which solution will achieve this goal?

A

Configure traffic routing using a weighted alias for the Lambda function versions.

B

Implement a canary deployment configuration for the Lambda function.

C

Use environment variables to manage traffic distribution between Lambda versions.

D

Set up a linear deployment configuration for the Lambda function.

Question #422 / 557

A developer is automating a new application deployment with AWS Serverless Application Model (AWS SAM). The new application has one AWS Lambda function and one Amazon S3 bucket. The Lambda function must access the S3 bucket to only write objects.

How should the developer configure AWS SAM to grant the necessary write privilege to the S3 bucket?

A

Reference a second Lambda authorizer function.

B

Add a custom S3 bucket policy to the Lambda function.

C

Create an Amazon Simple Notification Service (SNS) topic for only S3 object writes. Reference the topic in the template.

D

Add the S3WritePolicy template to the Lambda function's execution role.
