A company wants Reserved Instance savings but needs flexibility to change instance families/OS later as the workload evolves. Which RI type supports this?
A.Standard RI — fixed instance attributes
Standard locks attributes — deeper discount, less flexibility.
B.Convertible RI — exchangeable for different families/sizes/OS
Exchangeable attributes = Convertible. Correct.
C.Scheduled RI — for recurring time windows
Scheduled is for specific daily/weekly windows — different need.
D.Spot Instances
Spot has no commitment or attribute flexibility — interruptible capacity.
Why this answer
Convertible RIs (~54% discount vs Standard's ~72%) can be exchanged for different instance families, sizes, tenancy, or OS during the term — the flexibility option. Standard RI offers max discount with attribute lock; Scheduled RIs are time-window-bound.
