Question 1: Which of the following best describes the cloud computing value proposition for
a business?
A. Trading variable expenses for capital expenses
B. Trading capital expenses for variable expenses
C. Eliminating all IT expenses
D. Requiring long-term contracts for all services
Correct Answer: B. Trading capital expenses for variable expenses
One of the six advantages of cloud computing is trading capital expense (CapEx) for variable
expense (OpEx). Instead of investing heavily in data centers and servers before knowing how
they will be used, companies can pay only when they consume computing resources. This
reduces financial risk and improves cash flow.
Question 2: A company wants to avoid guessing how much infrastructure capacity they will
need. Which cloud advantage does this represent?
A. Stop spending money running and maintaining data centers
B. Benefit from massive economies of scale
C. Stop guessing capacity
D. Increase speed and agility
Correct Answer: C. Stop guessing capacity
Stop guessing capacity is one of the six advantages of cloud computing. With cloud
computing, companies can scale resources up or down based on actual demand rather than
over-provisioning to handle peak loads, which leads to wasted resources and unnecessary
costs.
Question 3: Which of the following is NOT one of the six advantages of cloud computing?
A. Trade capital expense for variable expense
B. Benefit from massive economies of scale
C. Guarantee 100% uptime for all services
D. Go global in minutes
Correct Answer: C. Guarantee 100% uptime for all services
The six advantages of cloud computing are: trade capital expense for variable expense,
benefit from massive economies of scale, stop guessing capacity, increase speed and agility,
stop spending money running and maintaining data centers, and go global in minutes. No

cloud provider guarantees 100% uptime; AWS provides service level agreements (SLAs) with
specific availability commitments.
Question 4: A company wants to deploy applications in multiple geographic locations to
serve customers with low latency. Which cloud advantage does this represent?
A. Stop guessing capacity
B. Go global in minutes
C. Trade capital expense for variable expense
D. Benefit from massive economies of scale
Correct Answer: B. Go global in minutes
Go global in minutes is one of the six advantages of cloud computing. AWS's global
infrastructure allows companies to deploy applications in multiple regions worldwide with
just a few clicks, providing lower latency and better experience for customers at a fraction of
the cost of traditional infrastructure.
Question 5: What is the primary difference between capital expenses (CapEx) and operational
expenses (OpEx)?
A. CapEx is ongoing; OpEx is a one-time investment
B. CapEx is a one-time upfront investment; OpEx is ongoing operational costs
C. CapEx and OpEx are the same
D. CapEx is for software; OpEx is for hardware
Correct Answer: B. CapEx is a one-time upfront investment; OpEx is ongoing
operational costs
Capital expenses (CapEx) are upfront investments in physical infrastructure such as servers,
storage, and networking equipment. Operational expenses (OpEx) are ongoing costs for
services consumed, such as cloud computing resources. Cloud computing shifts spending
from CapEx to OpEx.
Question 6: Which AWS tool helps compare the cost of running applications in an on-
premises data center versus on AWS?
A. AWS Cost Explorer
B. AWS Pricing Calculator
C. AWS Budgets
D. AWS Trusted Advisor
, WGU D282 | 4
Correct Answer: B. AWS Pricing Calculator
AWS Pricing Calculator (formerly Simple Monthly Calculator) allows users to estimate the
cost of AWS services and compare them with on-premises infrastructure costs. AWS Cost
Explorer visualizes historical spending, AWS Budgets sets cost alerts, and Trusted Advisor
provides optimization recommendations.
Question 7: What is the Total Cost of Ownership (TCO) in cloud computing?
A. Only the monthly cost of AWS services
B. The comprehensive cost of owning and operating IT infrastructure, including hardware,
software, personnel, and facilities
C. The cost of a single EC2 instance
D. The cost of data transfer only
Correct Answer: B. The comprehensive cost of owning and operating IT infrastructure,
including hardware, software, personnel, and facilities
TCO includes all costs associated with owning and operating IT infrastructure: hardware
purchase, software licensing, power and cooling, real estate, personnel, maintenance, and
more. Cloud TCO analysis compares these costs with the pay-as-you-go model of cloud
services.
Question 8: Which of the following is a benefit of cloud computing's massive economies of
scale?
A. Higher prices due to premium hardware
B. Lower variable costs because AWS can achieve higher economies of scale, which
translates into lower pay-as-you-go prices
C. Increased capital expenses
D. Reduced security
Correct Answer: B. Lower variable costs because AWS can achieve higher economies of
scale, which translates into lower pay-as-you-go prices
Because AWS aggregates usage from hundreds of thousands of customers, it achieves massive
economies of scale. This allows AWS to purchase hardware at lower costs and operate more
efficiently, passing savings to customers through lower pay-as-you-go prices.
Question 9: Which AWS Well-Architected Framework pillar focuses on the ability to recover
from failures and meet demand?
A. Operational Excellence
