Question #1078
Which factors contribute to AWS reducing the overall costs of computing resources compared to traditional on-premises infrastructure? (Choose two.)
AWS converts capital expenses into variable operational expenses based on usage.
AWS ensures 100% uptime for all hosted applications.
AWS removes the necessity for any in-house technical expertise.
AWS benefits from massive scale, allowing ongoing cost reductions.
AWS provides uniform pricing across all instance types.
Explanation
A is correct because AWS's pay-as-you-go model eliminates upfront capital expenses (CapEx) for hardware, replacing them with variable operational expenses (OpEx) based on actual usage. D is correct due to AWS's economies of scale, which lower infrastructure costs over time, allowing savings to be passed to customers.
B is incorrect because AWS does not guarantee 100% uptime (SLAs typically cap at 99.99%). C is false as AWS still requires technical expertise to manage cloud resources. E is incorrect because AWS pricing varies by instance type, region, and usage tiers.
Answer
The correct answer is: AD
