On every single practice exam including the NCEES ones, any question they have like this, where the answers are all just different codes, you would only need to know the "name" of each standard to solve the problem. For example in the SMS HVAC book, you would easily be able to get the answer to the question about energy codes if you knew the name of ASHRAE 55 as "Thermal Comfort" and knowing that doesn't deal with energy like the other ones do.
So I printed out a list of all the ASHRAE standards with their number and name next to each other. I also did this with the NFPA codes. I'm thinking any question that asks about "what code applies to this scenario?" I should be able to figure out with these lists.
Your ASHRAE Fundamentals book also has a huge list of the codes and standards in the back. They are organized by application or system and not alphabetically, which makes it harder to find if you just have the number, but there's a ton listed back there; good chance anything on the test will be on one of these lists.
At least that's how I plan on attacking these questions. I guess I'll know this week if I planned correctly.
