I’m pretty sure it’ll print 10 for the vector but not for the set.

Wait, does the set really ignore duplicates?

The set won't change, so it still has 1.

I think I know this one - a service template would be used to apply the same configuration to multiple CPEs, like option B. That seems like a common use case.

I'm pretty confident I know the answer to this one. HDFEC is simpler and faster than SDEFC, so option A is the false statement. I'll mark that one.

I'm pretty sure the no-arbitrage condition plays a key role in these problems. I just wish I could recall the exact formula we used for pricing these Treasury bond forwards.
