His paternal grandfather, , entered the service of the Habsburgs, thereby acquiring several Herrschaften (domains) in Bohemia, Moravia and Lower Austria, including . Questenberg's father chose this palace for his headquarters.

Questenberg studied philosophy in Vienna (1692–1694), and jurisprudence in Prague (1694–1696). Upon graduating, he received the title of Graf (Count) in 1696. In 1702, after spending three years taking his "Grand Tour" through Europe, he came to the Imperial Court in Vienna, in the capacity of a councilor. He was promoted to Reichshofrat in 1706, becoming a Privy Councilor and Chamberlain in 1723. His Viennese palace, now known as the Questenbergpalais, and mansions were all expanded in Baroque style.

Questenberg himself was an amateur composer and musician, playing the lute and theorbo; only two pieces of his have survived. He was also an enthusiastic collector of music; commissioning numerous works by contemporary composers. In addition, he maintained correspondence with Antonio Vivaldi and Johann Sebastian Bach.
