  1. On second thoughts things are as follows:

    Traffic between interfaces in the same zone is implicitly permitted.
    Traffic between interfaces in different zones but with the same security level is implicitly denied unless the “same-security permit” command is configured.

    Therefore correct answer is A.

    Sorry for the bad first reply..

  2. Same security zone means same security level. You can’t have the same zone applied to different interfeaces with different security level.
    Correct is answer B

  3. A) NO

    good is;

    B. Traffic between interfaces in the same zone is blocked unless you configure the same-security permit command
