問題文
A cluster requires a second authentication factor for administrative sign-in. A manager asks what the requirement adds, given that the passwords in use are long and unique and are stored in a managed vault. What does the second factor add?
選択肢
- A stolen password becomes shorter lived, because the platform shortens the interval at which the password has to be replaced once a second factor has been enrolled.
- A stolen password becomes traceable, because the record of the second factor lets a reviewer attribute the session to a named person rather than to an account.
- A stolen password stops being enough all on its own, because whoever presents it also has to hold the second factor at the moment of the attempt to sign in to the cluster.
- A stolen password becomes harmless, because the platform stops accepting it for the protocols which carry data once administrative access has been protected.
