This is a sample question from Sun's Certificate Success Guide.
9. Which statement is true?
A. Classes loaded into a browser from the local network are trusted.
B. Classes loaded into a browser from remote sources are trusted if they are signed.
C. Classes loaded into a browser from remote sources are trusted if they are in a signed jarfile.
D. Classes loaded from a jarfile on a remote source can sometimes be trusted even if the jarfile is unsigned.
E. Classes loaded from a signed jarfile are trusted if the public key associated with the jarfile's signature is
marked as trusted in the keystore.
The suggested answer is D. On the contrary, I think all options are right except D.
Should the question be "Which statement is false" instead?

I have to agree that that question is so tricky as to be almost unfair, but I think that their answer is correct.
Notice that D is the only answer that says "sometimes", so the other answers imply "always". Since I can think of subtle things that are wrong with ALL the answers, D looks like the "least incorrect" answer.
IIRC, if a jarfile is from a site that you have configued as trusted, then it's trusted. You can even specify that you trust everything and everyone, so D is literally true.
 
Yeah, but does being a ninja come with a dental plan? And what about this tiny ad?
