How can DynamoDB data be made available for long-term analytics with minimal operational overhead?
Option Ais the most automated and cost-efficient solution for exporting data to S3 for analytics.
Option Binvolves manual setup of Streams to S3.
Options C and Dintroduce complexity with EMR.
A company's application receives requests from customers in JSON format. The company uses Amazon Simple Queue Service (Amazon SQS) to handle the requests.
After the application's most recent update, the company's customers reported that requests were being duplicated. A solutions architect discovers that the application is consuming messages from the SQS queue more than once.
What is the root cause of the issue?
If the SQS visibility timeout is set shorter than the time it takes for the application to process and delete the message, the message becomes visible to other consumers and can be processed again, resulting in duplicate processing. This is a common cause of duplicate messages when using SQS.
Reference Extract from AWS Documentation / Study Guide:
'If the visibility timeout for a message is set shorter than the time it takes to process the message, the message becomes visible again and can be received and processed again, resulting in duplicate processing.'

A company runs multiple applications in multiple AWS accounts within the same organization in AWS Organizations. A content management system (CMS) runs on Amazon EC2 instances in a VPC. The CMS needs to access shared files from an Amazon Elastic File System (Amazon EFS) file system that is deployed in a separate AWS account. The EFS account is in a separate VPC.
Which solution will meet this requirement?
To access an EFS file system across accounts and VPCs, the EFS must be mounted using VPC peering or AWS Transit Gateway, and the EC2 instances must use the amazon-efs-utils package with the correct mount target or access point.
Using an EFS access point simplifies access management, especially across accounts, by providing a POSIX identity and access policy layer.
VPC sharing doesn't support EFS directly unless the subnet and resources are shared properly, which requires redeployment. Therefore, option D is the most complete and correct.
A financial company is migrating its banking applications to a set of AWS accounts managed by AWS Organizations. The applications will store sensitive customer data on Amazon Elastic Block Store (Amazon EBS) volumes. The company will take regular snapshots for backup purposes.
The company wants to implement controls across all AWS accounts to prevent sharing EBS snapshots publicly.
Which solution will meet these requirements with the LEAST operational overhead?
AWS provides EBS Block Public Access at the AWS Organizations level, which, when enabled, prevents EBS snapshots from being shared publicly across all member accounts. This is an organization-wide control that requires minimal configuration and no ongoing monitoring to prevent public sharing.
This directly satisfies the requirement:
Covers all accounts managed by Organizations.
Explicitly prevents public snapshot sharing.
Has the least operational overhead because it is a single centralized control.
AWS Config (Option A) only monitors and alerts, but does not prevent public sharing.
An IAM policy in the root account (Option C) is harder to enforce consistently across all accounts and may not cover all permission paths.
CloudTrail (Option D) only logs events and does not prevent public access.
A company is developing a highly available natural language processing (NLP) application. The application handles large volumes of concurrent requests. The application performs NLP tasks such as entity recognition, sentiment analysis, and key phrase extraction on text data.
The company needs to store data that the application processes in a highly available and scalable database.
Options:
A . API Gateway + DynamoDB:Provides high scalability, low latency, and seamless integration with Amazon Comprehend for NLP tasks.
B . HTTP API + Translate + ElastiCache:Translate is not relevant for NLP tasks like sentiment analysis or entity recognition. ElastiCache is unsuitable for permanent storage.
C . SQS + EC2 + RDS:Increases complexity and operational overhead. RDS may not scale effectively for high concurrent loads.
