WGU D118 CLOUD APPLICATIONS
PRACTICE EXAM 2026/2027 QUESTIONS
AND CORRECT DETAILED ANSWERS
1. Under the Shared Responsibility Model, which component is the customer responsible for
in an Infrastructure as a Service (IaaS) deployment?
A. Physical hardware and data center security
B. Virtualization layer management
C. Operating system patches and configuration
D. Hardware lifecycle management
Answer: C
Conceptual Explanation: In IaaS, the provider manages the physical infrastructure and
virtualization, while the customer is responsible for the OS, middleware, and applications.
2. Which cloud characteristic allows a system to handle increased load by adding resources,
and decrease them automatically when demand drops?
A. Vertical Scaling
B. High Availability
C. Elasticity
D. Fault Tolerance
,Answer: C
Conceptual Explanation: Elasticity is the ability to automatically scale resources up and
down based on demand.
3. A company is moving from an on-premises data center to a public cloud. How does this
shift affect their financial model?
A. Shift from CapEx to OpEx
B. Shift from OpEx to CapEx
C. Elimination of all operational costs
D. Increase in upfront capital requirements
Answer: A
Conceptual Explanation: Cloud computing shifts costs from Capital Expenditure (CapEx)
for hardware to Operational Expenditure (OpEx) for consumption-based services.
4. Which cloud service model would be most appropriate for a developer who wants to focus
purely on writing code without managing underlying servers or runtimes?
A. Platform as a Service (PaaS)
B. Software as a Service (SaaS)
C. Infrastructure as a Service (IaaS)
D. Database as a Service (DBaaS)
Answer: A
, Conceptual Explanation: PaaS provides a managed platform for developers to build,
deploy, and manage applications without worrying about the infrastructure.
5. What is the primary benefit of a multi-cloud strategy?
A. Lower latency for all users
B. Avoiding vendor lock-in
C. Reduced complexity in management
D. Lower total cost of ownership compared to single cloud
Answer: B
Conceptual Explanation: Multi-cloud allows organizations to use services from different
providers to avoid being dependent on a single vendor.
6. Which cloud deployment model is defined by resources being shared among several
organizations with similar requirements and compliance needs?
A. Public Cloud
B. Private Cloud
C. Community Cloud
D. Hybrid Cloud
Answer: C
Conceptual Explanation: Community clouds are shared by organizations with common
