Using AWS Organizations helps ensure what regarding CloudTrail?

Using AWS Organizations is beneficial because it supports centralized management and governance across multiple AWS accounts, including the configuration of services like AWS CloudTrail. When a new account is created within an AWS Organization, the organization can enforce policies that dictate how CloudTrail is configured, ensuring consistency and easy management across all accounts.

Centralized CloudTrail configuration is crucial for security and compliance, enabling an organization to have a unified view of API activity across all accounts without the need to independently configure each one. This centralization simplifies monitoring and auditing, making it easier to respond to security incidents or compliance requirements effectively.

The other options do not align with the functionalities that AWS Organizations provides for CloudTrail. For example, disabling all logging does not provide any security benefits and individual account logging options can lead to inconsistent logging practices across the organization. Also, while the AWS region might influence where CloudTrail logs are stored, AWS Organizations does not mandate that all accounts use the same region.
