I'm doing A+ practice exams.
One of the questions reads
The SATA standard defines data cable connector consisting of:
40 pins
34 pins
15 pins
7 pins
I chose 15 pins. It was wrong. The correct answer was 7.
Am I not understanding the question right? Or is their answer invalid?

Is SATA 7 or 15 pins?
The SATA standard defines data cable connector consisting of:
40 pins
34 pins
15 pins
7 pins
I chose 15 pins. It was wrong. The correct answer was 7.
A SATA data cable has 7 pins.
A SATA power cable has 15 pins.
Data connector
The SATA standard defines a data cable with seven conductors (3 grounds and 4 active data lines in two pairs) and 8 mm wide wafer connectors on each end.
Power connectors
SATA specifies a different power connector than the decades-old four-pin Molex connector used on Parallel ATA (PATA) devices. It is a wafer-type connector, like the SATA data connector, but much wider (15 pins versus seven) to avoid confusion between the two. Some early SATA drives included the old 4-pin Molex power connector together with the new 15-pin connector, but most SATA drives now have only the latter.
