1. AWS DataSync
2. Amazon ECR
3. Amazon Route 53
4. AWS WAF

Correct Answer: 1

Explanation

AWS DataSync is a managed data transfer service that helps organizations move data between on-premises storage systems and AWS storage services. It can automate and accelerate transfers while reducing the operational effort associated with managing transfer infrastructure. DataSync supports migration, data processing workflows, and data replication scenarios. ECR stores container images, Route 53 provides DNS services, and WAF protects web applications. Therefore, DataSync is the appropriate choice for managed movement of data between on-premises and AWS storage environments.

Question 323

Which AWS service provides a managed environment for deploying machine learning models and building machine learning applications?

1. Amazon SageMaker
2. Amazon QuickSight
3. Amazon Athena
4. Amazon Redshift

Question 330

Which AWS service provides a managed platform for running SQL queries directly against data stored in Amazon S3?

1. Amazon Redshift
2. Amazon Athena
3. Amazon RDS
4. Amazon Neptune

Correct Answer: 2

Explanation

Amazon Athena is a serverless interactive query service that allows customers to analyze data stored in services such as Amazon S3 using SQL. Because Athena is serverless, customers do not need to provision or manage database servers for supported query workloads. Redshift is a data warehouse, RDS provides managed relational databases, and Neptune provides graph database capabilities. Therefore, Athena is the appropriate service when users need to query S3 data directly using SQL without managing infrastructure.

Question 331

AWS Certificate Manager, or ACM, provides managed SSL/TLS certificates for supported AWS resources and services. It can simplify certificate provisioning and management and can support automatic renewal for eligible certificates used with integrated AWS services. KMS manages cryptographic keys, Secrets Manager stores application secrets, and IAM manages identities and permissions. Therefore, AWS Certificate Manager is the appropriate service when an organization needs to manage SSL/TLS certificates for supported AWS applications and services.

Question 333

Which AWS service allows applications to send notifications to multiple subscribers using a publish-and-subscribe model?

1. Amazon SQS
2. Amazon SNS
3. Amazon SES
4. Amazon MQ

Correct Answer: 2

Explanation

Amazon Simple Notification Service uses a publish-and-subscribe model in which publishers send messages to topics and subscribed endpoints can receive those messages. This makes SNS useful for broadcasting notifications to multiple consumers, applications, or supported endpoints. SQS provides queue-based asynchronous messaging, SES focuses on email delivery, and Amazon MQ provides managed message brokers. Therefore, SNS is the appropriate service when the same notification needs to be distributed to multiple subscribers.

Which AWS service provides access to third-party software and services that can be purchased for use with AWS workloads?

1. AWS Marketplace
2. AWS Artifact
3. AWS Service Catalog
4. AWS Organizations

Correct Answer: 1

Explanation

AWS Marketplace provides a digital catalog of third-party software, data products, and services that customers can acquire for use with AWS environments. Organizations can find products from independent software vendors and other providers and, where supported, manage purchases through their AWS accounts. Artifact provides AWS compliance documents, Service Catalog manages approved internal products, and Organizations manages AWS accounts. Therefore, AWS Marketplace is the appropriate service for discovering and acquiring third-party solutions for AWS workloads.

Question 337

Which AWS service provides a centralized location where customers can view AWS service events that may affect their resources?

1. AWS Health Dashboard
2. AWS CloudTrail
3. Amazon CloudWatch
4. AWS Config

AWS CloudFormation enables customers to define AWS infrastructure through reusable templates. These templates can describe resources and their relationships, allowing organizations to deploy consistent environments repeatedly. Infrastructure as code can reduce manual configuration and help standardize resource provisioning across development, testing, and production environments. Config monitors resource configurations, CloudTrail records API activity, and Service Catalog manages approved products. Therefore, CloudFormation is the appropriate service for reusable infrastructure templates and consistent deployment.

Question 339

Which AWS service can help organizations transfer files into and out of Amazon S3 using SFTP?

1. AWS Transfer Family
2. AWS DataSync
3. Amazon EFS
4. AWS Storage Gateway

Correct Answer: 1

Explanation

AWS Transfer Family provides managed file transfer services that support protocols such as SFTP and can integrate with supported AWS storage services, including Amazon S3. This allows organizations to continue using familiar file transfer workflows without operating their own SFTP servers. DataSync is designed for managed data transfers between storage systems, EFS provides file storage, and Storage Gateway supports hybrid storage integration. Therefore, AWS Transfer Family is the appropriate service for SFTP-based file transfers involving S3.

Question 340

Which AWS concept refers to designing a system so that a failure in one component does not cause the entire application to become unavailable?

1. Scalability
2. Fault tolerance
3. Elasticity
4. Cost optimization

Correct Answer: 2

Explanation

Fault tolerance refers to designing systems so they can continue operating despite the failure of individual components. This can involve redundant resources, independent failure domains, automated failover, and architectures that avoid relying on a single component. Scalability concerns the ability to handle changes in workload size, while elasticity focuses on automatically adjusting resources according to demand. Cost optimization focuses on controlling expenditure. Therefore, fault tolerance is the concept most directly associated with maintaining application operation when individual components fail.
