Interest Rate Options Vs. Caplet & Floorlet...

I recall at L2 or L1 that CFAI was a bit tricky in their interpretation of IR Options… Because an Int. Rate Options could behave in two different ways if it’s an option on the rate itself (Caps, Floors) or the underlying bond (Options on Futures). Do you think that CFAI would use differentiating terms for the two… ?

I’m sure they will tell you what the reference item is, ie interest rate call option vs Treasury future call option

Hope so… Thanks
