WGU D320 COMPLETE COMPREHENSIVE QUESTIONS AND CORRECT SOLUTIONS
OBJECTIVE ASSESSMENT NEWEST 2026 [ALREADY GRADED A+]
Question 1
Which cloud computing concept allows users to automatically provision and manage resources
such as server time and network storage without requiring human interaction with the service
provider?
A) Broad Network Access
B) Resource Pooling
C) On-Demand Self-Service
D) Rapid Elasticity
E) Measured Service
Correct Answer: C) On-Demand Self-Service
Rationale: On-demand self-service is a fundamental NIST characteristic that empowers the
consumer to acquire computing capabilities as needed automatically, eliminating the delays
associated with manual human intervention.
Question 2
Which characteristic ensures that cloud services are available over the network and accessed
through standard mechanisms that promote use by heterogeneous thin or thick client platforms?
A) Multi-tenancy
B) Broad Network Access
C) Measured Service
D) Resource Pooling
E) Scalability
Correct Answer: B) Broad Network Access
Rationale: Broad network access ensures that resources are accessible from various devices
(mobile phones, tablets, laptops) over the internet using standard protocols, regardless of
the user's location.
Question 3
A Cloud Service Provider (CSP) serves multiple consumers using a model where physical and
virtual resources are dynamically assigned and reassigned according to demand. This is known
as:
A) Rapid Elasticity
B) Measured Service
C) Resource Pooling
D) Single Tenancy
E) On-Demand Self-Service
Correct Answer: C) Resource Pooling
Rationale: Resource pooling involves the provider serving multiple customers using a multi-
tenant model, where resources are pooled to serve various users without them knowing the
exact physical location of the data.

Question 4
Which cloud concept refers to the ability to quickly scale resources up or down to meet shifting
requirements, often appearing to the consumer to be infinite?
A) Measured Service
B) Resource Pooling
C) Rapid Elasticity
D) Broad Network Access
E) Interoperability
Correct Answer: C) Rapid Elasticity
Rationale: Rapid elasticity allows a system to handle spikes in demand by automatically
increasing capacity and then releasing those resources when demand decreases, ensuring
cost-efficiency and performance.
Question 5
In cloud computing, what concept ensures that resource usage is monitored, controlled, and
reported, providing transparency for both the provider and the consumer?
A) Resource Pooling
B) Measured Service
C) Governance
D) Auditability
E) Portability
Correct Answer: B) Measured Service
Rationale: Measured service allows for a "pay-as-you-go" model where the CSP tracks
usage metrics. This provides the basis for transparent billing and resource optimization.
Question 6
Which actor in the cloud ecosystem is an individual or organization that contracts for and uses
services provided by a Cloud Service Provider?
A) Cloud Service Broker
B) Cloud Service Partner
) Cloud Service Customer
D) Cloud Service Carrier
E) Cloud Auditor
Correct Answer: C) Cloud Service Customer
Rationale: The Cloud Service Customer is the entity that maintains the business
relationship and uses the cloud services delivered by the provider.
Question 7
Which entity is responsible for making a service available to interested parties and delivering
that service to customers?
A) Cloud Service Broker
, 3
B) Cloud Service Partner
C) Cloud Service Provider (CSP)
D) Regulator
E) Cloud Auditor
Correct Answer: C) Cloud Service Provider (CSP)
Rationale: The CSP owns or manages the infrastructure and software necessary to deliver
cloud computing services to consumers.
Question 8
Which actor serves as an intermediary that manages the use, performance, and delivery of cloud
services, and negotiates relationships between CSPs and customers?
A) Cloud Service Carrier
B) Cloud Service Partner
C) Cloud Service Broker
D) Regulator
E) Cloud Auditor
Correct Answer: C) Cloud Service Broker
Rationale: A broker acts as a "middleman," helping customers choose the right services,
integrating multiple services, or providing additional value-added features.
Question 9
Which organization collaborates with a Cloud Service Provider (CSP) to enhance or distribute
the CSP's services, often through support or add-on tools?
A) Cloud Service Broker
B) Cloud Service Partner
C) Cloud Service Customer
D) Cloud Service Carrier
E) Regulator
Correct Answer: B) Cloud Service Partner
Rationale: Cloud partners work alongside CSPs to add functionality, provide integration
services, or help distribute the services to a wider market.
Question 10
Which authority is responsible for setting and enforcing standards and regulations for cloud
service operations to ensure compliance?
A) Cloud Auditor
B) Cloud Service Broker
C) Regulator
D) Cloud Service Carrier
E) Cloud Service Partner
Correct Answer: C) Regulator
, 4
Rationale: Regulators ensure that CSPs and customers adhere to legal, federal, and
contractual obligations such as HIPAA, GDPR, or SOX.
Question 11
What is the primary function of a Cloud Auditor?
A) To deliver the physical network connection
B) To manage the user's performance metrics
C) To conduct independent evaluations of cloud services to ensure security and performance
standards are met
D) To provision virtual machines for the customer
E) To develop software for the CSP
Correct Answer: C) To conduct independent evaluations of cloud services to ensure security
and performance standards are met
Rationale: Auditors provide oversight via external evaluations (like SOC or FedRAMP) to
verify that the provider's claims regarding security and availability are accurate.
Question 12
Which cloud actor provides the connectivity and transport of cloud services from CSPs to Cloud
Consumers?
A) Cloud Service Broker
B) Cloud Service Partner
C) Cloud Service Carrier
D) Regulator
E) Cloud Auditor
Correct Answer: C) Cloud Service Carrier
Rationale: The carrier is the networking entity (like an ISP or telecommunications provider)
that provides the physical "highway" for data to travel.
Question 13
Which cloud service model is characterized by the delivery of software applications over the
internet, where the provider manages the underlying infrastructure and platform?
A) Infrastructure as a Service (IaaS)
B) Platform as a Service (PaaS)
C) Software as a Service (SaaS)
D) Database as a Service (DBaaS)
E) Security as a Service (SECaaS)
Correct Answer: C) Software as a Service (SaaS)
Rationale: SaaS (referred to as the "Application" layer in the prompt) allows users to access
finished software via a web browser without managing any of the technical backend.
