Question #783 / 1019

A company processes financial transaction logs using a legacy application hosted on Amazon EC2 instances. They want to migrate these logs to an AWS managed service to reduce operational overhead while ensuring all data changes are recorded in an immutable, cryptographically verifiable format for audit purposes. Which solution BEST meets these requirements cost-effectively?

A

Migrate the transaction logs to an Amazon Redshift cluster for analytical processing.

B

Migrate the transaction logs to an Amazon Neptune cluster to model transaction relationships.

C

Migrate the transaction logs to an Amazon Timestream database for time-series analysis.

D

Migrate the transaction logs to an Amazon Quantum Ledger Database (Amazon QLDB) ledger.

Question #223 / 1019

A company has deployed a Java Spring Boot application as a pod that runs on Amazon Elastic Kubernetes Service (Amazon EKS) in private subnets. The application needs to read and write objects to an Amazon S3 bucket. A solutions architect must ensure that the application can interact with the S3 bucket without exposing traffic to the internet.

Which combination of steps should the solutions architect take to accomplish this goal? (Choose two.)

A

Attach an IAM role that grants S3 permissions to the EKS pod.

B

Attach an IAM user with S3 access policies to the EKS pod.

C

Allow outbound connectivity to S3 through the private subnets\u2019 route tables.

D

Create a Gateway-type VPC endpoint for S3.

E

Store AWS access keys in environment variables within the application.

Sample Questions

Question #380 / 529

A company uses an Amazon API Gateway HTTP API to collect sensor data from IoT devices. The API is integrated with an AWS Lambda function that processes the data by sending it to a legacy on-premises system via a VPN connection. The legacy system frequently becomes unavailable, causing the Lambda function to fail and data to be lost.

A solutions architect needs to redesign the solution to ensure no data is lost and that processing can resume once the legacy system is available again. The solution must minimize changes to the existing architecture.

What should the solutions architect do to meet these requirements?

A

Create an Amazon Simple Queue Service (Amazon SQS) queue. Configure the queue as a dead-letter queue for the Lambda function.

B

Create two Amazon Simple Queue Service (Amazon SQS) queues: a main queue and a dead-letter queue. Update the API integration to send data directly to the main queue. Configure the Lambda function to consume messages from the main queue with retries, and route failed messages to the dead-letter queue.

C

Create an Amazon EventBridge event bus with a rule to archive all events. Update the API to send data to the event bus. Configure the Lambda function to process events from the archive when the legacy system recovers.

D

Create an Amazon Kinesis Data Firehose delivery stream. Update the API integration to send data to Kinesis Firehose. Configure Firehose to retry failed deliveries to the Lambda function indefinitely.

Question #429 / 529

A company operates a legacy application on VMware vSphere VMs hosted on premises. The application processes data stored in a specialized binary format that can only be accessed through the application itself. The servers and application were manually configured. The company's disaster recovery plan requires temporarily migrating the application to AWS during on-premises outages, with an RPO of 5 minutes, and ensuring a return to on-premises hosting post-recovery. Operational overhead must be minimized.

Which solution meets these requirements with the LEAST operational effort?

A

Use AWS Application Migration Service (MGN) to replicate the VMs to AWS. During an outage, launch the replicated EC2 instances automatically. Replicate changes back to on-premises post-recovery using MGN.

B

Implement AWS Elastic Disaster Recovery. Continuously replicate the VMs to EC2 instances with EBS volumes. Failover to AWS during outages using Elastic Disaster Recovery, then re-sync data back to on-premises post-recovery.

C

Configure AWS Backup to create snapshots of on-premises VMs and store them in Amazon S3. During an outage, restore snapshots to new EC2 instances and manually reattach EBS volumes.

D

Set up VMware HCX to extend the on-premises environment to AWS. Replicate VMs to AWS during normal operations. During an outage, redirect traffic to AWS-based VMs using HCX mobility groups.

Sample Questions

Question #102 / 557

A video streaming application uses the AWS SDK for JavaScript on the frontend to retrieve temporary security credentials from AWS STS. The application's media files are stored in an Amazon S3 bucket and distributed via a CloudFront distribution. The current implementation has the AWS credentials hard-coded in a configuration file within the application's source code. The developer needs to eliminate the hard-coded credentials while maintaining the ability to retrieve temporary credentials securely.

Which solution meets these requirements?

A

Add a Lambda@Edge function to the distribution. Configure it to trigger on viewer request. Assign an execution role to the function with permissions to access AWS STS. Move all credential retrieval logic from the frontend into the function.

B

Add a CloudFront function to the distribution. Configure it to trigger on viewer request. Assign an execution role to the function with permissions to access AWS STS. Move all credential retrieval logic from the frontend into the function.

C

Add a Lambda@Edge function to the distribution. Configure it to trigger on viewer request. Embed the credentials from the configuration file into the function's code. Move all credential retrieval logic from the frontend into the function.

D

Add a CloudFront function to the distribution. Configure it to trigger on viewer request. Embed the credentials from the configuration file into the function's code. Move all credential retrieval logic from the frontend into the function.

Question #225 / 557

A global IoT platform is ingesting millions of sensor readings per second from devices worldwide. The data must be processed in real-time by multiple analytics services simultaneously. Which service enables concurrent processing by all consumers while maintaining low latency and high cost-efficiency?

A

Amazon SNS with fan-out to an SQS queue for each analytics service

B

Amazon SNS with fan-out to an SQS FIFO (first-in, first-out) queue for each analytics service

C

Amazon Kinesis Firehose

D

Amazon Kinesis Data Streams
