Actual exam question for Arcitura Education's S90.02 exam

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.

No way, it has to be more than 2 commits to succeed!

B is the right answer. Missing vote means rollback.

I vaguely recall that for a transaction to be successful, you need a majority of Commit votes. So, option D might be the right choice.

I’m a bit confused because I thought as long as there was one Commit vote, it would be fine. But now I’m not so sure if that applies here.

I think I came across a similar question where the consensus was that a missing vote means the transaction fails. So, I’m leaning towards option B.

I remember studying that in WS-AtomicTransaction, if there's a missing vote, it usually leads to a rollback, but I'm not entirely sure.

I'm not totally sure about this one. I know WS-AtomicTransaction is designed to ensure consistency, but I'm not certain how it handles a scenario like this with a missing vote.

Okay, I think I've got this. Since two of the services voted to commit, and there was no abort vote, the transaction should be considered successful, even with the missing vote.

Hmm, I'm a bit confused on this one. I'll need to review the details of the WS-AtomicTransaction specification to understand the correct behavior.

This is a tricky one. I'll need to think carefully about the WS-AtomicTransaction protocol and how it handles missing votes.

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?
