Which of the following is a digital identity management option supported by CyberArk?

Amazon Cognito is indeed a digital identity management option supported by CyberArk. It serves as a user authentication and management solution that allows developers to securely manage and authenticate users for their applications. By integrating with Amazon Cognito, CyberArk can enhance its capabilities to manage user identities and access permissions more efficiently.

Azure Active Directory (AD) is also a popular digital identity management system, widely used by organizations for single sign-on (SSO) and identity management in cloud environments. Although Azure AD is a legitimate option for identity management, it is not the correct answer in this context when compared to Amazon Cognito, which may have been more specifically highlighted in the context of the question for CyberArk environments.

Twitter Auth, while it allows for login and authentication using Twitter accounts, is not generally categorized as a comprehensive identity management solution on par with those like Amazon Cognito or Azure AD within the context of enterprise solutions.

In summary, Amazon Cognito aligns well with CyberArk's focus on secure digital identity management, making it the appropriate choice among the options presented.
