Cloud Concepts A free question from our original CLF-C02 practice exam. Try it, then open the answer to see why each option is right or wrong.
A company owns licences for a database product that are priced per physical CPU socket. It wants to keep using these licences after moving to AWS. Which Amazon EC2 option is designed to support this kind of bring-your-own-licence (BYOL) requirement?
Choose one answer.
- AA. Spot Instances
- BB. Dedicated Hosts
- CC. On-Demand Instances on shared hardware
- DD. License-included Amazon Machine Images
Show the answer and explanation
Answer: B
- A. Wrong: Spot Instances use spare capacity at a discount and can be interrupted. They do not give you visibility of physical sockets for licensing.
- B. Right: Correct. A Dedicated Host is a physical server fully dedicated to you, which lets you bring existing per-socket, per-core or per-VM software licences.
- C. Wrong: Shared-tenancy instances do not expose a dedicated physical server, so per-socket licence terms usually cannot be met.
- D. Wrong: License-included means the licence cost is part of the AWS price, so the company would pay again instead of using the licences it already owns.
Explanation
Licensing is part of cloud economics. With bring your own licence (BYOL), you reuse licences you already own. Some licences are tied to physical hardware, and Dedicated Hosts give you a whole physical server so you can apply per-socket, per-core or per-VM licences. The alternative, license-included, builds the licence cost into the hourly price.
