Commonly confused with
The JLPT rarely asks whether you recognise a pattern — it asks which of several similar patterns fits. These are the ones ～だけのことはある is tested against.
vs ～だけあって
だけあって comes before the result clause ('because ~, as expected the result is…'); だけのことはある typically comes after, as a concluding 'no wonder' remark.
vs ～わけだ
わけだ simply states a logical conclusion; だけのことはある adds admiration that the result is deserved and lives up to expectations.
