I tried the trial version of the whizlabs J2EE 484 simulator. It's fantastic, yes, truly fantastic apart from the price. I wonder why the tool doesn't allow me to do a copy & paste of the question. Most of the times, we prefer to do a copy & paste of the unsure questions, including some bits of the explanation to discuss it in the technical forums. If whizlabs are a bit apprehensive about their copyright acts, may be they can provide a feature that would allow the candidate to discuss the specific question in the whizlabs technical discussion forums or at javaranch in this forum. Enthuware products have this feature. It allows them to discuss the questions with the question number in the JDiscuss.com forum(s).
