Dear student 
As far as i can understand... The question is  - buffer solution '' can'' be prepared
Sodium acetate and HCl will react and form acetic acid and NaCl
NaCl is SASB salt, it will not affect pH
If HCl is limiting, then the solution contain only acetic acid and Sodium acetate, which is a buffer
