Hi

Can you please tell how and in what case the combination of Database Mirroring with transactional replication achieved higher availability of the replication stream?

Regards

Is this an interview question?

Anyway, this is more a question for the administration forums.
Furthermore, the question is too vague. There are many types of database mirroring.
But you can start here:

Sorry, but I can't guide, for several reasons:

* I'm not that well versed in high availability, and I don't feel like explaining something that I don't understand fully myself
* high availability is such a big topic, it just can't be explained in a forum post

I can suggest you to pick up a book about SQL Server Administration and read up on the subject.
Or, with some research, you can find all the information readily available online.
