Have you ever had a situation where you had a number of alternatives to choose from? How did you go about choosing one?
By asking this question, the interviewer is trying to determine your decision-making skills. Information security analysts are presented with a lot of data and must make quick and accurate decisions. Your ability to do this and have a reliable process to sort through data and choose the best course of action is critical. You should be able to describe the process and perhaps give an example of how you've applied it while doing your job.
"During my work, I am often presented with a great deal of information and several different alternatives to choose from. This can be overwhelming at times. My process to narrow down the choices is to eliminate the ones that are not feasible. I then look at the remaining options and determine which would have the best outcome and would require a minimal amount of resources or costs. Once I select the option, I move forward with confidence and don't second guess myself."
