N10-009 Question 44
Single answerDeployment models: Public, Private, HybridA mid-sized healthcare company wants to modernize its infrastructure. Patient records and imaging systems must remain on company-controlled systems to meet strict compliance requirements, but the company also wants to use cloud-based email, collaboration tools, and on-demand compute resources for seasonal analytics workloads. Which deployment model best meets these requirements?
- A
Public cloud
- B
Private cloud
- C
Hybrid cloud
- D
Community cloud
Show answer and explanation
Correct answer: C
Explanation
The best answer is Hybrid cloud. A hybrid model is used when an organization needs to keep some applications or data in a private environment while leveraging public cloud services for scalability, cost efficiency, or convenience. This is common in regulated industries such as healthcare, where sensitive systems may need stronger internal control, while SaaS offerings and elastic compute can be hosted in the public cloud. This aligns with common cloud deployment definitions used by NIST, which distinguishes public, private, community, and hybrid deployment models. From a Network+ perspective, candidates should recognize the practical business and compliance drivers behind selecting hybrid cloud rather than viewing deployment models as purely theoretical categories.
- A. Incorrect.
Public cloud is incorrect because it would place workloads in a provider-owned shared environment. While public cloud is well suited for scalable services such as email, collaboration, and burstable compute, it does not by itself satisfy the requirement to keep regulated patient records and imaging systems on company-controlled infrastructure.
- B. Incorrect.
Private cloud is incorrect because it can meet the requirement for company-controlled systems and tighter compliance oversight, but it does not best address the organization's additional goal of using cloud-based services and elastic resources for seasonal demand. Choosing only private cloud would limit the flexibility and scalability the scenario specifically requests.
- C. Correct.
Hybrid cloud is correct because it combines private infrastructure for regulated or sensitive workloads with public cloud services for scalable or less sensitive workloads. In this scenario, keeping patient records and imaging systems on company-controlled systems while using cloud email, collaboration, and temporary analytics capacity is a textbook example of a hybrid deployment model.
- D. Incorrect.
Community cloud is incorrect because it is designed for organizations with shared concerns, such as mission, policy, or compliance needs, to use a shared cloud environment together. The scenario does not describe multiple organizations sharing infrastructure; it describes one company splitting workloads between internal control and cloud services.
