The airplane has how many DC Power Centers?

Explanation:
DC power centers are the main hubs that distribute 28-volt DC power to the airplane’s DC buses. Having two centers provides redundancy and keeps essential electrical loads powered even if one center or its path is faulted. Each center can feed its own set of buses and can be isolated for maintenance without losing all DC power, improving reliability and fault containment. On the CRJ-550 you indeed have two DC Power Centers, so the correct answer is two.
