WGU D118 OBJECTIVE ASSESSMENT
EXAM VERSION A QUESTIONS AND
CORRECT DETAILED ANSWERS
(VERIFIED ANSWERS)
1. Which cloud deployment model involves a composition of two or more distinct cloud
infrastructures that remain unique entities but are bound together by standardized
technology?
A. Public Cloud
B. Hybrid Cloud
C. Community Cloud
D. Private Cloud
Answer: B
Conceptual Explanation: A hybrid cloud is a combination of public and private clouds,
allowing data and applications to be shared between them while maintaining their unique
identities.
2. In the Shared Responsibility Model, who is primarily responsible for the security of the
underlying physical infrastructure in a public cloud environment?
A. The Customer
,B. The Cloud Service Provider (CSP)
C. The Third-party Auditor
D. Both the Customer and CSP equally
Answer: B
Conceptual Explanation: The CSP is responsible for ‘security of the cloud’ (hardware,
software, networking, and facilities), while the customer is responsible for ‘security in the
cloud’.
3. What is the primary financial advantage of shifting from an on-premises data center to a
cloud environment?
A. Moving from OPEX to CAPEX
B. Increasing Depreciation Costs
C. Moving from CAPEX to OPEX
D. Eliminating all maintenance costs
Answer: C
Conceptual Explanation: Cloud computing allows organizations to shift from Capital
Expenditure (upfront hardware costs) to Operational Expenditure (pay-as-you-go utilities).
4. Which concept refers to the ability of a system to increase its capacity by adding more
power to an existing node, such as increasing RAM or CPU?
A. Horizontal Scaling
, B. Vertical Scaling
C. Elasticity
D. Load Balancing
Answer: B
Conceptual Explanation: Vertical scaling (scaling up) involves adding resources to a
single node, whereas horizontal scaling (scaling out) involves adding more nodes.
5. Which service model provides the highest level of control over the operating system and
middleware for the customer?
A. SaaS
B. PaaS
C. FaaS
D. IaaS
Answer: D
Conceptual Explanation: Infrastructure as a Service (IaaS) provides virtualized
computing resources, giving users control over the OS, storage, and deployed applications.
6. What term describes the time it takes for a system to recover after a failure?
A. Recovery Point Objective (RPO)
B. Mean Time Between Failures (MTBF)
