Question #: 88
Topic #: 1

Using WS-AtomicTransaction you wrap 3 SOAP-based Web services in a single transaction. When it is time to vote on the outcome of the transaction, 2 of the services vote to commit the changes made during the transaction, but a vote from the third service is not received. What will happen? Select the correct answer.

AThe changes are committed because the transaction is considered successful as long as no Abort votes are received.

BThe changes are rolled back because the transaction is considered unsuccessful when there is a missing vote.

CThe changes are committed because the transaction is considered successful as long as one Commit vote is received.

DThe changes are aborted because a transaction can only be considered successful when more than 2 Commit votes are received.

Haha, imagine if the third service was just out to lunch and forgot to vote. What a way to ruin the whole transaction!

D sounds a bit too strict. Isn't it enough to have a majority of Commit votes?

C seems plausible, but I'm not sure that's how WS-AtomicTransaction works. Gotta study up on that.

Hmm, I think B is the correct answer. If one of the services doesn't vote, the transaction can't be considered successful.
