WGU D320 MANAGING CLOUD SECURITY
(JYO2) – 100+ PRACTICE QUESTIONS WITH
VERIFIED ANSWERS & RATIONALES
SECTION 1: CLOUD COMPUTING FUNDAMENTALS &
DEPLOYMENT MODELS
Question 1
Which cloud characteristic allows customers to rapidly
provision computing resources without requiring human
interaction from the service provider?
A. Broad network access
B. Measured service
C. Resource pooling
D. On-demand self-service
Correct Answer: D
Rationale: On-demand self-service is one of the five essential
cloud characteristics defined by NIST. It enables users to
provision computing capabilities automatically whenever
needed without direct interaction with the provider. Broad
network access refers to availability over the network,
,measured service relates to metering capabilities, and
resource pooling involves serving multiple customers from
shared resources .
Question 2
Which cloud service model gives customers the MOST
responsibility for managing operating systems and
applications?
A. SaaS
B. PaaS
C. IaaS
D. FaaS
Correct Answer: C
Rationale: In Infrastructure as a Service (IaaS), customers
manage operating systems, middleware, applications, and data,
while the cloud provider manages the physical infrastructure.
SaaS requires the least customer responsibility (provider
manages everything), and PaaS falls in between with the
provider managing the OS and runtime environment .
Question 3
,A multinational company wants to reduce infrastructure costs
while maintaining complete control over sensitive financial
systems. Which cloud deployment model is the best fit?
A. Public cloud
B. Community cloud
C. Private cloud
D. Hybrid cloud
Correct Answer: C
Rationale: A private cloud provides dedicated infrastructure
for a single organization, offering greater control,
customization, and security for sensitive data. Public clouds
are multi-tenant and offer less control, community clouds
serve specific groups, and hybrid combines both but may not
provide the dedicated control required for sensitive financial
systems .
Question 4
Which deployment model provides the highest level of control
and security for organizations with strict compliance
requirements?
A. Public cloud
B. Private cloud
, C. Community cloud
D. Hybrid cloud
Correct Answer: B
Rationale: A private cloud provides dedicated infrastructure
for a single organization, offering the highest level of control
over security configurations, physical infrastructure, and
compliance implementations. This makes it ideal for
organizations with strict regulatory requirements that cannot
be met in multi-tenant environments .
Question 5
Which cloud service model requires the customer to manage
the security of the operating system, applications, and data?
A. IaaS
B. PaaS
C. SaaS
D. FaaS
Correct Answer: A
Rationale: In Infrastructure as a Service (IaaS), the
customer is responsible for securing the operating system,
applications, and data. The cloud provider secures only the
underlying infrastructure. PaaS shifts OS management to the
