Which DTA Maintenance Tool module would you use to grant group access to a person?

The choice to use the People module in the DTA Maintenance Tool for granting group access to a person is correct because this module specifically manages personnel data within the Defense Travel System. The People module provides functionality for adding or modifying individual users, assigning roles, and managing their access to different features within the system.

By using this module, a Defense Travel Administrator (DTA) can effectively grant or modify access permissions for individuals based on their group affiliations. This capability is crucial when working with multiple users who need similar access levels to streamline processes and ensure that all personnel can efficiently manage their travel arrangements.

The other options, while relevant to various administrative tasks, do not directly pertain to the management of individual user access. The Reports module is focused on generating reports related to travel data; Access Logs pertain to tracking who accessed what information within the system; and the Settings module deals with configuring system preferences rather than user access. Therefore, the People module is the appropriate choice for granting group access to individuals within the DTA Maintenance Tool.
