As the interview progresses, the interviewer will continue to ask you about the commands you use to accomplish a task in this role. This could be a question that suggests that there are multiple answers since the interviewer used the plural form of commands. Interviewers will often give you hints and the content and the format of the questions they ask.

It is critically important that you carefully listen to the interviewer's entire question before beginning to formulate your answer or begin to respond. This will ensure that you understand the question and are providing the information the interviewer expects in your response. Suppose you do not understand the question or aren't clear about what the interviewer is asking. In that case, it is appropriate to ask a clarifying question or begin your answer with a clarifying statement.

"There are two commands you can use if you don't know what SQL is currently being used by a session. These are vsql and vsql_area. vsql stores statistics about each child version of a SQL statement stored in the Shared Pool, while vsqlarea summarizes these statistics per sqlid."
