Place roast in large resealable food storage bag. Combine wine, soy sauce, garlic, rosemary, Dijon mustard, and dry mustard in small bowl. Pour over roast. Seal bag; turn to coat. Marinate in refrigerator 4 to 12 hours, turning several times.
Preheat oven to 425°F. Spray 13 x 9-inch baking pan with nonstick cooking spray. Place potatoes, Brussels sprouts, and carrots in pan. Remove roast from marinade. Pour marinade over vegetables; toss to coat. Cover vegetables with foil; roast 30 minutes. Stir.
Place tenderloin on vegetables. Roast, uncovered, 35 to 45 minutes or until internal temperature of roast reaches 135°F for medium-rare to 150°F for medium when tested with meat thermometer inserted into thickest part of tenderloin.
Transfer tenderloin to cutting board; tent with foil. Let stand 10 to 15 minutes before carving. (Internal temperature will continue to rise 5°F to 10°F during stand time.) Reserve drippings from roasting pan to make gravy, if desired.
Stir vegetables; continue roasting if not tender. Slice tenderloin; arrange on serving platter with roasted vegetables.
