Procedure; Environment - Non Weather Related
[We] were flying the FORCK2 departure and were level at 10;000 feet; experiencing small altitude changes due to turbulence of a cloud layer at 10;000 feet; when the flight experienced an RA. Between the intersections of PAXTN and HANUH; ATC had called traffic in vicinity of aircraft with one A321 flying at 11;000 feet directly above our aircraft. The crossing traffic at 11;000 feet caused an additional small altitude gain due to wake turbulence; which did not exceed 200 feet. I responded to the altitude deviation by starting a slow descent of 200 feet per minute. Upon regaining 10;000 feet the aircraft received an RA from an aircraft below us that was climbing. Initial estimate would put that aircraft between 1;000-1;500 feet below our aircraft and climbing when the initial RA went off. I responded to that RA by initiating a climb and keeping the Flight Director in the RA Green Zone. First Officer called ATC and stated that we were responding to an RA and had initiated a climb. At 10;500 feet; the RA stated clear of conflict and we leveled off. After the below aircraft showed clear behind us; I started the descent back to 10;000 feet which was our assigned ATC altitude. Upon being clear of conflict; Captain and First Officer both mentioned the conflicting aircraft was then 1;700 feet below the aircraft. No further issues occurred throughout the duration of the flight.Turbulence from cloud layer at our assigned altitude caused minor altitude deviations. Wake turbulence from A321 crossing overhead of our aircraft 1;000 feet above caused major wake turbulence immediately following its passing from right to left.De-congestion of airspace when an aircraft is getting light to moderate turbulence at the base of a cloud layer. Within two minutes we were given multiple traffic alerts from ATC in regards to aircraft crossing. Other aircraft also could have been held lower or given a shallower climb to limit the crossing points of our system.
EMB-175 Captain reported encountering wake turbulence departing DFW from an A321 above them.
