  1. Guys, what end user do you know personally that would know how to check that and/or have a reason to check last login? Come on! No user ever thinks like that, you’re trying to think like a sec dude in an average-end user’s body – it does not work like that. The only feasible option is option A. The awareness training would’ve prompted user to report the suspicious activity in the first place. I am not sure why you try to talk about types of controls, the question does not in any shape or form indicate that it was concerned about preventative or detective or anything similar.

    A is the correct answer, don’t push it. People come here to learn and prep for the exam and this is not helping.

  2. I chose B as well

    I think A is more preventative, it wouldn’t have helped him detect it much, unless they teach B in the class.

  3. A and B are feasible options.
    However, question asks about what would allow THE USER to more quickly IDENTIFY the unauthorized use of credentials. A (security awareness training) would help in avoiding the user to be successfully phished.
    B (Last login verification) would show the user that someone from another country access his account (like GMail does).

    I would stick with B (Last login verification).

  4. A and B are feasible options.
