The question was not really concerned with whether we were RVSM approved/equipped/able. We were on that day.
The point being, should we have been asked our RVSM status? Or everytime we are cleared to a none standard level or any other cruise level, for that matter, should we be announcing 'affirm RVSM'. I understood it from the 'Phraseology' section of the syllabus that that was the response to the question 'confirm RVSM approved'.
