I thought views were temporary, not just when the postmaster is running.

I’m a bit confused about option E; I thought views persist in the database even when the postmaster is not running.

I practiced a question similar to this, and I think views can be created and dropped, so option A sounds familiar.

I remember that views are often described as virtual tables, so I think option B might be correct.

Hmm, I'm a bit unsure about this one. I'll need to review my notes on the Experience Editor to see if I can recall the right approach.

This looks like a tricky SAN configuration issue. I'll need to carefully read through the options and the exhibit to figure out the best approach.

I think a load balancer distributes incoming traffic across multiple servers... but I'm not entirely sure.
