Even I came across the link and discussed with my friends working at sun. According to them sun cannot do anything legally in this matter(heard that positively sun is changing the assignments for both developer and architect from december). According to the sun's agreement you should not reveal or disclose the actual questions in any format. But here the person is not disclosing the actual assignment but revealing his designs(I doubt whether the author has the right to disclose them or not). More to this, one should feel moral responsibilty that he should not be a copy cat. Hope while evaluating the assignment sun will catch the allys?
But those who have already visited the link can use the designs as an idea for things that should be taken care while developing component diagrams etc.,(Try to understand between copying and aquiring knowledge about the concepts). So that it may be useful to the aspirants(please lemme know if i was wrong).That's why i am not mentioning the link.
