Answer 1

In short, yes. Quoting from the official documentation here (towards the middle of the page):

Persisted or Volatile: Data can be persisted to disk for durability against large-scale outages (for example, a datacenter power outage). Some Reliable Collections also support a volatile mode (with Caveats) where all data is kept in-memory, such as a replicated in-memory cache.

Further, at the bottom of this page, you can find more details about exactly which types of Reliable Collections can be persisted and/or be made volatile.
