Question #21 / 1019

A media company is developing a global real-time voting system for a popular TV show. The system must handle millions of votes per second with millisecond latency during peak voting windows and ensure high availability. Which architecture will meet these requirements with the LEAST operational overhead?

A

Deploy the voting application on Amazon EC2 instances in Auto Scaling groups across multiple Availability Zones. Use an Application Load Balancer (ALB) to distribute traffic. Store vote counts in Amazon RDS for PostgreSQL with read replicas for scalability.

B

Host the voting frontend in an Amazon S3 bucket with Amazon CloudFront for global caching. Use EC2 instances behind an ALB to process votes via REST APIs. Store vote data in Amazon Aurora with auto-scaling enabled.

C

Containerize the voting application and deploy it on Amazon EKS. Use Kubernetes Horizontal Pod Autoscaler to manage traffic spikes. Store vote results in Amazon ElastiCache for Redis and persist final counts in Amazon RDS for MySQL.

D

Host the static voting interface in Amazon S3 with Amazon CloudFront for low-latency delivery. Use Amazon API Gateway and AWS Lambda to process votes via serverless APIs. Store vote data in Amazon DynamoDB with on-demand capacity.

Question #127 / 1019

A financial analytics firm is migrating its on-premises infrastructure to AWS. They require 15 TB of storage with the highest possible I/O performance for real-time transaction processing, 350 TB of highly durable storage for a data lake housing historical transaction data, and 1 PB of cost-effective storage for compliance backups that must be retained for seven years.

Which combination of AWS services should a solutions architect propose to fulfill these requirements?

A

Amazon EBS for high I/O performance, Amazon S3 for the data lake, and Amazon S3 Glacier for compliance backups.

B

Amazon EC2 instance store for high I/O performance, Amazon EFS for the data lake, and Amazon S3 Glacier for compliance backups.

C

Amazon EC2 instance store for high I/O performance, Amazon S3 for the data lake, and Amazon S3 Glacier for compliance backups.

D

Amazon EBS for high I/O performance, Amazon EFS for the data lake, and Amazon S3 for compliance backups.

Sample Questions

Question #491 / 529

A company is developing a latency-sensitive application. Part of the application includes several AWS Lambda functions that need to initialize as quickly as possible. The Lambda functions are written in .NET and contain initialization code outside the handlers to load configuration files, initialize dependencies, and establish database connections.

Which solution will meet the startup performance requirement MOST cost-effectively?

A

Move all the initialization code to the handlers for each Lambda function. Activate Lambda SnapStart for each Lambda function. Configure SnapStart to reference the unpublished $LATEST version of each Lambda function.

B

Publish a version of each Lambda function. Create an alias for each Lambda function pointing to the published version. Configure provisioned concurrency for each alias and enable SnapStart for the unpublished $LATEST versions.

C

Publish a version of each Lambda function. Enable SnapStart for the published versions. Configure provisioned concurrency for the $LATEST versions and move the database connection logic into the handlers.

D

Update the Lambda functions to include a pre-snapshot hook. Move the database connection initialization into the handlers. Publish a version of each Lambda function. Activate Lambda SnapStart for the published versions of the Lambda functions.

Question #47 / 529

A company is developing a serverless application hosted on AWS Lambda within a VPC. The application must communicate with an external API that mandates all requests originate from a single static public IPv4 address. The company needs to ensure the Lambda functions can securely access the API while adhering to this requirement.

Which solution will enable the application to meet the external provider's condition?

A

Deploy a NAT gateway in a public subnet. Assign an Elastic IP address to the NAT gateway. Update the VPC route tables to direct outbound traffic from the Lambda function's subnet to the NAT gateway.

B

Create an egress-only internet gateway. Attach an Elastic IP address to the gateway. Modify the Lambda function's security group to route traffic through the egress-only internet gateway.

C

Configure an internet gateway with an Elastic IP address. Update the Lambda function's elastic network interface to associate with the internet gateway's Elastic IP address.

D

Attach an internet gateway to the VPC. Assign an Elastic IP address to the internet gateway. Configure the main route table in the VPC to route all outbound traffic through the internet gateway.

Question #554 / 557

A developer has an application running in AWS Account X. The application needs to access an AWS Secrets Manager secret encrypted by an AWS KMS key in AWS Account Y. The application's role has permissions to retrieve the secret from Account Y but cannot decrypt it due to KMS key policies.

The developer must update the KMS key policy in Account Y to allow the role in Account X to decrypt the secret. The solution must follow the principle of least privilege.

Which permissions should be added to the KMS key policy to meet these requirements?

A

kms:Decrypt and kms:DescribeKey

B

secretsmanager:GetSecretValue and secretsmanager:DescribeSecret

C

kms:*

D

secretsmanager:*
