B. Capital expenses are replaced with variable expenses — ✅ CORRECT
One of the key benefits of using AWS Cloud is the replacement of large capital expenditures (CapEx) with operational expenses (OpEx). Traditionally, companies had to invest significant amounts in purchasing servers, storage, and other IT hardware, which had to be ordered, installed, and maintained on-premises. AWS eliminates this need by allowing customers to pay only for the resources they actually use.
Benefits:
• No need for large upfront investments.
• Pay-as-you-go model.
• Scale up and down without wasting funds.

D. Increased agility — ✅ CORRECT
AWS enables organizations to rapidly deploy and scale IT infrastructure, which translates into greater business agility. Companies can quickly test new ideas, spin up environments in minutes (instead of weeks), and adjust them as needed, drastically reducing time-to-market.
Benefits:
• Faster prototyping.
• Real-time deployment of changes.
• Infrastructure flexibility and automation.
