Today's question of the course (2780B), how do licensing options mix with multiple instances. The course points out the choices on installation;

  • Per processor
  • Per Server
    • Device Client Access License
    • User Client Access License

That's about it, but as always, MS-Licensing is more complicated than a single page in the text-book. If you want to know it all, there is an SQL Server licensing white-paper, covering;

  • Virtualization / Multi-instances
  • Multi-core processors
  • Fail-over technologies (Cluster, Database Mirroring, Log Shipping)
  • Multiplexing
  • Separation of components over multiple servers.
  • SQL vs Workgroup CAL's
  • Special programs for ISV's and hosting providers
  • Downgrading

For just Virtualization and Multi-instancing, read this section of the above white-paper. For more info on licenses and pricing, visit How to buy SQL Server. Keep in mind that pricing and licensing may vary based on your location.

... and other Microsoft exams. Since it's Microsoft's objective to have Performance Based Testing (a.k.a. simulations) in all MCTS exams, you'll want to have some peace of mind as to how they are scored (and about the relevance towards the total exam).

Read the full story at Trika's blog, I'm pretty sure more questions and answers will appear in the comments.
