1. Question 1Cloud Concepts [Benefits]

   A startup wants to deploy a new application but is concerned about the large upfront cost of buying and setting up servers. Which benefit of the AWS Cloud directly addresses this concern?

   • A.Trade capital expense for variable expense
   • B.Go global in minutes
   • C.Benefit from massive economies of scale
   • D.Stop guessing about capacity
   Show answer and explanation

   Correct answer: A

   Correct. This is a core economic benefit of cloud computing. Instead of a large upfront Capital Expense (CapEx) for physical hardware, the startup can pay for computing resources as an ongoing, variable Operational Expense (OpEx), scaling as needed.

   Why the other options are wrong

   B. Incorrect. Going global in minutes refers to deploying into new Regions quickly to reduce latency for users worldwide. It addresses reach, not the initial cost of infrastructure.

   C. Incorrect. Economies of scale mean AWS achieves lower per-unit costs across its aggregate usage and passes those savings on as lower prices. That lowers the ongoing rate, not the upfront purchase.

   D. Incorrect. This benefit removes the need to over- or under-provision hardware ahead of demand. It addresses capacity planning rather than the capital cost of acquiring servers.

2. Question 2Cloud Concepts [Economics]

   Which of the following is an example of Operational Expenditure (OpEx) in the AWS Cloud?

   • A.Buying a multi-year software license for a fixed cost.
   • B.Building a new on-premises data center facility.
   • C.Paying for the number of hours an Amazon EC2 instance runs.
   • D.Purchasing physical servers for a data center.
   Show answer and explanation

   Correct answer: C

   Correct. Paying for services on a consumption basis, such as the hourly or per-second cost of an EC2 instance, is an Operational Expenditure (OpEx). It's a variable cost tied to the ongoing operation of the business.

   Why the other options are wrong

   A. Incorrect. A large, upfront payment for a multi-year license is typically treated as a Capital Expenditure (CapEx).

   B. Incorrect. The cost of constructing a physical facility is a significant Capital Expenditure (CapEx).

   D. Incorrect. Purchasing physical hardware is a classic example of a Capital Expenditure (CapEx), as it is a large, upfront investment.

3. Question 3Cloud Concepts [Design Principles]Choose all that apply

   A finance manager is trying to optimize the company's AWS spending. Which of the following are design principles for cost optimization in the AWS Cloud? (Select TWO)

   • A.Stop spending money on undifferentiated heavy lifting.
   • B.Use a single, large instance for all workloads.
   • C.Go global in minutes.
   • D.Adopt a consumption model.
   • E.Test systems at production scale.
   Show answer and explanation

   Correct answer: A, D

   Correct. This principle recognizes that AWS handles the undifferentiated work of data center operations - racking, stacking, and powering servers - and that managed services remove the operational burden of running operating systems and applications, letting you focus on your customers and business projects.

   Correct. This principle involves paying only for the computing resources you consume and increasing or decreasing usage depending on business requirements, rather than using fixed, over-provisioned resources.

   Why the other options are wrong

   B. Incorrect. This is the opposite of a best practice. Cost optimization often involves using smaller, right-sized instances and scaling horizontally.

   C. Incorrect. This is a general benefit of the cloud, not a specific cost optimization design principle.

   E. Incorrect. This is a design principle for reliability, not directly for cost optimization.

4. Question 4Cloud Concepts [Benefits]Choose all that apply

   A retail company is evaluating moving from its on-premises data center to the AWS Cloud. Which of the following are direct benefits of this move? (Select TWO)

   • A.Stopping spending money on running and maintaining data centers.
   • B.The ability to deploy globally in minutes.
   • C.Eliminating the need to manage application-level permissions.
   • D.Guaranteed reduction in total monthly IT spending.
   • E.Receiving a free, dedicated Technical Account Manager (TAM).
   Show answer and explanation

   Correct answer: A, B

   Correct. A major benefit of the cloud is that AWS handles the undifferentiated heavy lifting of managing physical data centers, including power, cooling, and physical security, allowing the customer to focus on their own business.

   Correct. The AWS global infrastructure allows a customer to deploy their application in multiple geographic regions around the world with just a few clicks, enabling rapid global expansion.

   Why the other options are wrong

   C. Incorrect. Managing application-level permissions is part of the customer's responsibility for security *in* the cloud.

   D. Incorrect. While the cloud offers opportunities for cost savings, it does not guarantee a reduction, especially if resources are not managed efficiently.

   E. Incorrect. A designated TAM is a feature of the premium AWS Enterprise Support plan and is not a default benefit.

5. Question 5Cloud Concepts [Well-Architected]

   A company is using AWS IAM to enforce the principle of least privilege for all users and services. This practice aligns with which pillar of the AWS Well-Architected Framework?

   • A.Cost Optimization
   • B.Reliability
   • C.Security
   • D.Performance Efficiency
   Show answer and explanation

   Correct answer: C

   Correct. Implementing a strong identity foundation, which includes using the principle of least privilege, is a core design principle of the Security pillar.

   Why the other options are wrong

   A. Incorrect. While good security can prevent costly incidents, the principle itself is a security concept.

   B. Incorrect. The Reliability pillar is focused on system uptime and recovery.

   D. Incorrect. The Performance Efficiency pillar is focused on the efficient use of resources.
