WGU D320 by Brian MacFarlane Exam with Questions and Answers

WGU D320 by Brian MacFarlane Exam with Questions and Answers A multinational company wants to reduce infrastructure costs while maintaining complete control over sensitive financial systems. Which cloud deployment model is the best fit for this requirement? a. Public cloud b. Community cloud c. Private cloud d. Hybrid cloud Correct Answer: c. Private cloud Rationale: A private cloud provides dedicated infrastructure for a single organization, offering greater control, customization, and security for sensitive workloads. Public clouds are shared environments, while hybrid clouds combine public and private resources but do not guarantee complete isolation for all systems. An organization wants developers to focus only on application code without managing operating systems, storage, or runtime environments. Which cloud service model best supports this goal? a. Infrastructure as a Service (IaaS) b. Platform as a Service (PaaS) c. Software as a Service (SaaS) d. Disaster Recovery as a Service (DRaaS) Correct Answer: b. Platform as a Service (PaaS) Rationale: PaaS abstracts infrastructure management and provides development tools, middleware, and runtime environments so developers can focus on coding and deployment. IaaS still requires operating system management, while SaaS delivers complete applications to end users.
