WGU D318 – Cloud Applications Exam
Final Prep Exam (Latest Update
2026/2027) Questions and Verified
Answers | 100% Correct | Grade A.
1. A company wants to reduce the time required to provision virtual
servers while ensuring consistency across deployments. Which
cloud practice best accomplishes this goal?
A. Manual configuration after deployment
B. Installing applications individually on each server
C. Infrastructure as Code (IaC)
D. Purchasing additional physical hardware
Rationale: Infrastructure as Code (IaC) automates the provisioning and
configuration of cloud infrastructure using templates or code. This
ensures environments are deployed consistently, minimizes human error,
improves scalability, supports version control, and accelerates
deployment compared to manual configuration.
2. Which cloud service model provides customers with virtual
machines, storage, and networking while allowing them to install
and manage their own operating systems?
,A. Software as a Service (SaaS)
B. Infrastructure as a Service (IaaS)
C. Platform as a Service (PaaS)
D. Function as a Service (FaaS)
Rationale: IaaS delivers virtualized computing resources over the
internet. Customers manage operating systems, middleware, and
applications, while the cloud provider manages the underlying physical
infrastructure.
3. Which cloud deployment model is owned and operated by a third-
party provider and shared among multiple customers?
A. Private cloud
B. Public cloud
C. Hybrid cloud
D. Community cloud
Rationale: A public cloud is operated by a cloud service provider and
shared among multiple organizations. Customers benefit from
scalability, lower costs, and minimal infrastructure management.
4. Which service model requires the least customer responsibility for
managing infrastructure?
A. Infrastructure as a Service
B. Platform as a Service
C. Software as a Service
D. Colocation Services
,Rationale: SaaS provides complete software applications managed by
the provider. Customers simply access the application while the provider
manages hardware, networking, operating systems, updates, and
security of the application platform.
5. What is the primary purpose of virtualization in cloud computing?
A. Increase physical server size
B. Reduce internet bandwidth
C. Allow multiple virtual machines to run on one physical server
D. Replace operating systems permanently
Rationale: Virtualization enables multiple isolated virtual machines to
share the resources of a single physical host, improving hardware
utilization, flexibility, scalability, and cost efficiency.
6. Which characteristic of cloud computing allows resources to
automatically increase or decrease based on workload demand?
A. Fault tolerance
B. High availability
C. Elasticity
D. Encryption
Rationale: Elasticity enables cloud resources to scale automatically
according to workload requirements, helping organizations optimize
performance while minimizing unnecessary costs.
, 7. A cloud administrator wants applications to remain operational
even if an entire data center becomes unavailable. Which strategy
best supports this objective?
A. Local backups only
B. Single availability zone deployment
C. Multi-region deployment
D. Manual server recovery
Rationale: Deploying applications across multiple geographic regions
provides resilience against regional outages and significantly improves
disaster recovery capabilities.
8. Which technology allows developers to package applications along
with their dependencies into lightweight, portable units?
A. Hypervisors
B. Virtual machines
C. Containers
D. SAN storage
Rationale: Containers package applications and all required
dependencies, ensuring consistent execution across different
environments while consuming fewer resources than virtual machines.
9. Which cloud pricing model charges customers only for the
resources they actually consume?
A. Fixed annual license
B. Perpetual licensing
