Correct answer:
-
Organizing and managing AWS resources based on specific criteria
AWS Resource Groups allow you to group resources together for easier management, monitoring, and automation based on tags or resource types.
Other options — why they're wrong:
-
Monitoring resource performance in real-time
AWS Resource Groups are not primarily designed for real-time performance monitoring, but rather for organization and management.
-
Automating resource deployment across multiple regions
While AWS has automation tools, resource groups are not specifically for automating deployments across regions.
-
Creating billing reports for resource usage
Billing reports are generated through AWS Cost Management tools, not specifically through AWS Resource Groups.

Q149. What is the primary benefit of using AWS Outposts for hybrid cloud solutions?
Correct answer:
-
Seamless integration with on-premises infrastructure
AWS Outposts allows organizations to run AWS services on-premises, providing a consistent hybrid cloud experience.

-
Increased security and compliance options
While security is important, AWS Outposts' primary benefit is the seamless integration it offers rather than just security enhancements.
-
Ability to run applications in multiple regions
Running applications in multiple regions is a feature of AWS but not specifically a primary benefit of AWS Outposts for hybrid solutions.
Q150. Which AWS service provides capabilities for managing and optimizing cloud costs and budgets?
Correct answer:
-
AWS Cost Explorer
AWS Cost Explorer allows users to visualize and manage their cloud spending, making it easier to analyze costs and optimize budgets.
Other options — why they're wrong:
-
AWS CloudFormation
AWS CloudFormation is primarily used for provisioning and managing infrastructure as code, not for cost management.
-
AWS Lambda
AWS Lambda is a compute service that runs code in response to events but does not provide cost management features.
-
AWS Trusted Advisor
AWS Trusted Advisor offers best practices and recommendations but is not specifically focused on managing and optimizing costs directly.
