WGU D118 CLOUD APPLICATIONS AND
SERVICES OBJECTIVE ASSESSMENT
PRACTICE EXAM QUESTIONS AND
CORRECT DETAILED ANSWERS
(VERIFIED ANSWERS)
1. In the Shared Responsibility Model for Infrastructure as Service (IaaS), which of the
following is typically the responsibility of the customer?
A. Physical security of the data center
B. Hypervisor management
C. Hardware maintenance
D. Operating system patching and configuration
Answer: D
Conceptual Explanation: In IaaS, the provider manages the physical infrastructure and
virtualization layer, while the customer is responsible for the OS, applications, and data.
2. A company needs to scale their application to handle a sudden surge in traffic by adding
more instances of the same size. What type of scaling is this?
A. Vertical Scaling
B. Elasticity
,C. Diagonal Scaling
D. Horizontal Scaling
Answer: D
Conceptual Explanation: Horizontal scaling (scaling out) involves adding more resource
units, such as virtual machines or containers, rather than increasing the power of a single
unit.
3. Which cloud characteristic allows for resources to be automatically provisioned and
released based on demand?
A. Resource Pooling
B. Measured Service
C. Broad Network Access
D. Rapid Elasticity
Answer: D
Conceptual Explanation: Rapid elasticity is the ability to quickly scale resources up or
down to match current demand, often automatically.
4. Which type of hypervisor runs directly on the underlying host’s physical hardware?
A. Type 2 (Hosted)
B. Type 1 (Bare Metal)
C. Kernel-based VM
, D. Container-based
Answer: B
Conceptual Explanation: Type 1 hypervisors run directly on the hardware, offering higher
performance and stability compared to Type 2, which runs on an OS.
5. A business determines that they can afford to lose no more than 4 hours of data in the
event of a disaster. Which metric defines this requirement?
A. Recovery Point Objective (RPO)
B. Maximum Tolerable Downtime (MTD)
C. Recovery Time Objective (RTO)
D. Service Level Agreement (SLA)
Answer: A
Conceptual Explanation: Recovery Point Objective (RPO) defines the maximum age of
files that must be recovered from backup storage for operations to resume after a disaster.
6. Which deployment model is shared by several organizations with similar concerns such as
security requirements or policy compliance?
A. Public Cloud
B. Community Cloud
C. Hybrid Cloud
D. Private Cloud
