Though featuring only three starters from last year's All-Ireland hurling semi-final, Cork easily accounted for WIT in their quarter-final at Pairc Ui Chaoimh.
That a largely experimental side came through their test was heartening for selector Kieran Kingston ahead of next week's semi-final.
"It (the game) was low-key, I suppose," he said, "but it gave us a chance to look at guys that we mightn't have otherwise.
"Secondly, it gives us another game next week and a chance to look at guys again. That's the purpose of the competition for us. We had a very strong bench but we know what those fellas can do. We're delighted with the win, delighted with the way fellas played and with the attitude shown."
Corner-forward Adrian Mannix was one of those to take his chance, scoring 2-4, the two second-half goals finishing off WIT's chances.
Earlier, a converted penalty from goalkeeper Anthony Nash had been followed by an excellent effort from Jamie Coughlan to put Cork into a 2-3 to 0-2 lead, and though Michael Sheedy's goal brought the college side back into contention, by half-time Cork's lead was 2-10 to 1-4, Mannix with four points.
A succession of Cian McCarthy frees early in the second period edged Cork further clear, and the good work of Daniel Kearney in midfield ensured plentiful supply for the forwards, with Mannix taking advantage in the closing stages as he found the net twice.
