問題文

Staff at a logistics company already sign in to a corporate directory. A new provider portal should accept those same accounts without storing another password. Which arrangement achieves this?

選択肢

1. The portal trusts the shared service account so that sign-in relies on the existing employee credential and the provider never keeps the separate additional password described in the identity documentation.
2. The portal trusts the central corporate directory so that sign-in relies on the existing employee credential and the provider never keeps the separate duplicate password described in the identity documentation.
3. The portal trusts the local portal database so that sign-in relies on the existing employee credential and the provider never keeps the separate duplicate password described in the identity documentation.
4. The portal trusts the exported credential file so that sign-in relies on the existing employee credential and the provider never keeps the separate additional password described in the identity documentation.
