  1. Agree good response is D
    passwords have to match but you have to know that this part concerns the KEY-CHAIN part, and we call this part KEY-STRING.

    But if timers are not OK, hellos messages can be a problem.

    So the time is an issue for authentication fiel in EIGRP world

    1. Time here is refering to the time on the neighboring routers, not to the ‘timers’.

      Here is asking to ‘key rollover’ to work correctly, for that to work correctly the time must be the saem on all routers involved, so D seems to be the correct answer.
      If password is incorrect authintication will fail but key rollover will succeed.
