Question #982 / 1019

A company has an Amazon DynamoDB table that contains sensitive data. The company has an application that runs on virtual machines in an on-premises data center. The company currently uses AWS IAM Identity Center.

The application requires temporary access to the DynamoDB table. The company wants to grant the application secure access to the data in the DynamoDB table.

Which solution will meet these requirements?

A

Create a DynamoDB resource policy that permits access to the table from the public IP address range of the company\u2019s on-premises data center.

B

Use IAM Roles Anywhere to obtain security credentials in IAM Identity Center that grant access to the DynamoDB table. Configure the virtual machines to assume the role by using the AWS CLI.

C

Install the AWS CLI on the virtual machine. Configure the AWS CLI with access keys from an IAM user that has access to the DynamoDB table.

D

Create an IAM user and policy that grants access to the DynamoDB table. Store the access key and secret key for the IAM user in AWS Secrets Manager. Configure the application to retrieve the access key and secret key at startup.

Question #87 / 1019

A company uses AWS Lambda functions triggered by Amazon API Gateway to process orders and store them in an Amazon Aurora PostgreSQL database. During scheduled database maintenance periods, the Lambda functions experience connection timeouts, resulting in lost order data. A solutions architect needs to ensure that all orders are processed even when the database is undergoing maintenance.

Which solution meets these requirements?

A

Provision an Amazon RDS proxy to manage database connections. Configure the Lambda functions to connect to the RDS proxy.

B

Increase the Lambda functions' timeout setting to the maximum. Implement exponential backoff retry logic in the code to retry database writes.

C

Store the order data temporarily in Lambda ephemeral storage. Use a secondary Lambda function to process the stored data once the database is available.

D

Write the order data to an Amazon Simple Queue Service (Amazon SQS) standard queue. Deploy a separate Lambda function to consume messages from the queue and persist the data to the database.

Sample Questions

Question #488 / 529

A company hosts its public API using Amazon API Gateway integrated with AWS Lambda functions. The API serves external clients and partners, who also access a legacy monolithic application running on a single Amazon EC2 instance. The company wants to improve security by preventing denial of service (DoS) attacks, identifying vulnerabilities, and guarding against common web exploits.

What should a solutions architect recommend to address these requirements?

A

Use AWS WAF to protect both the API Gateway API and the legacy application. Configure Amazon Inspector to analyze the EC2 instance. Configure Amazon GuardDuty to block malicious API access attempts.

B

Use AWS WAF to protect the API Gateway API. Configure Amazon Inspector to assess both the API Gateway and EC2 instance. Configure Amazon GuardDuty to monitor for malicious activity targeting the APIs.

C

Use AWS WAF to protect the API Gateway API. Configure Amazon Inspector to analyze the EC2 instance. Configure Amazon GuardDuty to monitor for malicious attempts to access the APIs.

D

Use AWS WAF to protect the API Gateway API. Configure Amazon Inspector to protect the EC2 instance. Configure Amazon GuardDuty to block unauthorized access to both APIs.

Question #58 / 529

A financial institution operates a mission-critical monolithic application hosted on an Amazon EC2 instance running Amazon Linux 2. The compliance team mandates daily backups of the encrypted Amazon EBS volume data to an Amazon S3 bucket. The operations team lacks SSH access to the instance and cannot disrupt the application's availability.

Which solution satisfies these requirements?

A

Attach an IAM role with Amazon S3 write permissions to the instance. Use AWS Systems Manager Session Manager to access the instance and execute commands to transfer data to Amazon S3.

B

Create an Amazon Machine Image (AMI) of the instance without rebooting. Launch a new EC2 instance from the AMI, attach an IAM role with S3 permissions, and copy the data to Amazon S3.

C

Use Amazon Data Lifecycle Manager (DLM) to automate EBS snapshot creation. Configure a Lambda function to copy snapshot data to Amazon S3.

D

Stop the instance, create an AMI, launch a new instance from the AMI with an IAM role for S3 access, and run commands to copy data to Amazon S3.

Sample Questions

Question #531 / 557

A company operates a microservices application on Amazon EC2 instances that requires dynamic configuration parameters shared across services. The application must poll for parameter updates every 10 minutes and cache retrieved values to reduce latency. Which solution meets these requirements MOST operationally efficiently?

A

Store the parameters in AWS Secrets Manager. Use Amazon ElastiCache with a lazy loading strategy to cache values. Update the application to poll ElastiCache directly every 10 minutes.

B

Store the parameters in an Amazon DynamoDB table. Use DynamoDB Accelerator (DAX) with a lazy loading strategy for caching. Modify the application to poll DynamoDB every 10 minutes.

C

Store the parameters in AWS AppConfig. Deploy the AWS AppConfig Agent on the EC2 instances to poll for updates every 10 minutes. Configure the application to retrieve parameters from the agent's localhost endpoint.

D

Store the parameters in AWS Systems Manager Parameter Store. Update the application to poll Parameter Store every 10 minutes using the AWS SDK and cache values in memory.

Question #96 / 557

A developer is designing a service that uses an Amazon S3 bucket to store uploaded documents. The service requires an AWS Lambda function to process each document and generate a summary. Additionally, each document upload must trigger an SMS notification. The developer needs to configure the document processing and SMS notifications efficiently.

A

Create an Amazon Simple Notification Service (Amazon SNS) topic. Configure S3 event notifications to publish to the SNS topic. Subscribe the Lambda function to the SNS topic. Add an SMS subscription to the SNS topic.

B

Create an Amazon Simple Queue Service (Amazon SQS) queue. Configure S3 event notifications to send messages to the SQS queue. Subscribe the Lambda function to the SQS queue. Add an SMS subscription to the SQS queue.

C

Create an Amazon Simple Notification Service (Amazon SNS) topic. Configure S3 event notifications to publish to the SNS topic. Create an Amazon EventBridge rule to trigger the Lambda function when documents are uploaded. Add an SMS subscription to the EventBridge rule.

D

Use Amazon EventBridge to monitor the S3 bucket. Create an EventBridge rule that triggers the Lambda function and sends an SMS notification via Amazon Simple Email Service (Amazon SES) when documents are uploaded.
