The eyes of Joe Schmidt were on Leinster 'A' as they outscored Pontypridd two tries to nil at Donnybrook.
"This is huge for these players," said academy manager Girvan Dempsey.
"They want to put their hands up for selection for that senior jersey.
"We were disappointed the way it worked out last year, losing the semi-final against Munster in extra-time.
"We're keen to go at least one better this season. It is another chance to win a competition."
Centre Brendan Macken struck either side of the interval, putting an 11-point gap between the sides that Pontypridd were never likely to breach.
His first took advantage of out-half Noel Reid's clever pass and his second was a flying finish from centre Jordan Coghlan's no-look feed.
Leinster will have to take down Leeds Carnegie in the final round of the pool to guarantee their passage into the knockout phase.
