That is patently not true. Look up the law. If there is CCW involved they cannot ask you that.
I have read the CC law a few times and there is nothing in the law restraining a police officer from asking you if you are carrying a weapon.
By law in the state of GA you are not required to volunteer information to a police officer that you are armed. There is nothing precluding an officer from asking you if you are carrying weapons or have them in your vehicle. Being evasive is likely to just give them probable cause to search your vehicle.
