@dcontesti The answer presented as correct was a) Labeling.
I chose C, based on the potential legal ramifications that could present themselves in that category.
I honestly felt, while this one was definitely a headscratcher... it was one of the better practice questions I've come across. I can see the reasoning where in the end, if your sensitive information isn't labeled, the other three steps are rather moot.
if you look at the lifecycle management of any asset first is identifying, second is labelling, third is storage, retention, fourth is sanitization or deletion. so CISSP exam wants you to identify the best answer and not sometimes the correct answer. so if you go through your question. labelling is the best answer as you don't have identification, what is next? i will go with labelling. always wear a hat of a external consultant when you gives cissp exams. never wear a technical specialist and be on the troubleshooting mode when you appear for cissp.
there is no future in this question neither it is mentioned that we need protection from. what is the most important step in protecting sensitive information.
first step is identify. this guys have identified the information
second step is classify, this guys have given it an sensitive information
next step is to label and then it is storage, retention and then it is deletion.
