Which AWS service helps in maintaining an organized directory structure for multihierarchical data?

AWS Directory Service is designed to provide a managed directory service that enables the organization and management of user and resource data within a hierarchical structure. It allows businesses to set up and manage directories for various applications and services seamlessly. This service can act as a central hub for managing users and resources, facilitating the organization of data in a structured way across multiple layers, making it particularly useful for enterprises that require a systematic approach to user management and access.

Amazon Cognito is focused primarily on user sign-up, sign-in, and access control for mobile and web applications, rather than organizing data hierarchically.

AWS Key Management Service is primarily used for creating and controlling encryption keys for data security, not for maintaining an organized directory structure.

Amazon GuardDuty is a threat detection service that continuously monitors for malicious or unauthorized activity within AWS accounts. Its purpose is security-focused rather than data organization.

By focusing on user and resource management within a structured directory format, AWS Directory Service stands out as the correct solution for maintaining an organized directory structure for multihierarchical data.
