Understand concepts of cloud economics, including fixed versus variable costs, the cost of on-premises environments, rightsizing and licensing strategies such as Bring Your Own License.

A company already owns valid software licences for a database engine and wants to keep using those licences on AWS instead of paying for new ones bundled into the service. Which licensing strategy supports this goal?

• ABring Your Own License, applying the licences the company already owns to its AWS workloadscheck_circle Correct
• BRightsizing the database instance so that it runs on the smallest possible compute size
• CSwitching the workload to a variable cost model so the licence fee scales with usage
• DTotal cost of ownership analysis to compare the on-premises and cloud licence prices

Why A is correct: Bring Your Own License lets a company reuse software licences it has already bought, avoiding the cost of new licences included in a service.

Why B is wrong: Rightsizing controls how much compute you pay for, but it does nothing to let the company reuse software licences it already owns.

Why C is wrong: Changing to variable pricing affects how charges accrue, not whether existing licences can be carried over to the cloud.

Why D is wrong: A total cost of ownership study compares overall costs, but it is an analysis method, not the strategy that reuses owned licences.
