WGU D118 OBJECTIVE ASSESSMENT
EXAM VERSION B - CLOUD
FOUNDATIONS QUESTIONS AND
CORRECT DETAILED ANSWERS
(VERIFIED ANSWERS)
1. Under the Shared Responsibility Model for an Infrastructure as a Service (IaaS)
deployment, which of the following is typically the responsibility of the cloud service
provider?
A. Physical security of the data center
B. Data encryption at rest
C. Operating system patching
D. Identity and access management (IAM)
Answer: A
Conceptual Explanation: In IaaS, the provider manages the physical infrastructure,
including hardware and data centers, while the customer is responsible for the OS, data,
and access controls.
2. A company is experiencing rapid growth and needs to scale its compute resources
automatically based on demand. Which cloud characteristic best describes this capability?
A. Rapid elasticity
,B. Broad network access
C. Resource pooling
D. Measured service
Answer: A
Conceptual Explanation: Rapid elasticity refers to the ability to scale resources up and
down quickly as needed, often automatically.
3. Which cloud service model would be most appropriate for a development team that wants
to focus on writing code without managing the underlying operating system or middleware?
A. IaaS
B. DaaS
C. SaaS
D. PaaS
Answer: D
Conceptual Explanation: Platform as a Service (PaaS) provides a framework for
developers to build and deploy applications without handling the underlying infrastructure
layers.
4. Which financial concept represents the shift from high upfront costs to variable monthly
expenses in a cloud migration?
A. EBITDA to Gross Margin
, B. OpEx to CapEx
C. ROI to TCO
D. CapEx to OpEx
Answer: D
Conceptual Explanation: Moving to the cloud shifts expenses from Capital Expenditure
(CapEx - fixed assets) to Operational Expenditure (OpEx - day-to-day costs).
5. In the context of Disaster Recovery, what does Recovery Point Objective (RPO) measure?
A. The time it takes to restore a system
B. The total cost of the recovery operation
C. The maximum age of files that must be recovered from backup storage
D. The uptime percentage of the service
Answer: C
Conceptual Explanation: RPO defines the maximum amount of data loss measured in time
(e.g., 4 hours of data lost) that an organization can tolerate.
6. Which technology allows multiple virtual machines to run on a single physical host by
managing hardware resource allocation?
A. Container Engine
B. API Gateway
