Airbus ECAM says to apply the QRH procedure... So apply it.
Various instructors can tell you different stuff, best to just do what the ECAM/QRH procedure says. If most is non-applicable then you will be done with it in about 1 minute anyway.
But I guess you already experienced that as you would not have posted this question if the sim instructor had agreed with you that the QRH does not apply.
Can this non-topic be closed?
