Which statement is true about granting and revoking permission levels?

The statement about a DTA (Designated Trust Authority) needing to hold a permission level in order to grant or revoke that same level captures an essential principle in the management of permissions within an organization. This requirement ensures that individuals with the authority to make changes to permission levels possess adequate understanding and authority relative to that level. Essentially, it promotes accountability and security within the permissions framework.

By imposing this prerequisite, organizations can mitigate risks associated with mismanagement or unauthorized access, as only those with an appropriate level of clearance and understanding can modify permissions. This policy helps maintain a structured and secure system where changes are made judiciously and with a clear understanding of their implications.

The other options do not reflect best practices regarding permission management. For instance, granting permissions without restrictions or revoking levels without holding them could lead to unaccountable power dynamics and potential security breaches. Documentation of changes is also typically required to ensure transparency and a clear audit trail of permission adjustments, which is not addressed in the selected statement.
