300-420 Question 322
Select 2A company is planning to migrate its on-premises application to the cloud. They want to retain sensitive workloads on-premises due to compliance requirements while utilizing cloud services to support scalability and cost-efficiency for less sensitive workloads. Additionally, they need a development platform for building custom applications and access to pre-built software solutions for specific business needs. Which cloud deployment model and service models should they choose?
- A
Hybrid cloud deployment with IaaS and PaaS
- B
Public cloud deployment with SaaS and PaaS
- C
Private cloud deployment with IaaS and SaaS
- D
Hybrid cloud deployment with SaaS, PaaS, and IaaS
- E
Public cloud deployment with IaaS and SaaS
Show answer and explanation
Correct answers: A, D
Explanation
The company’s requirements point to a hybrid cloud deployment model, as it allows sensitive data and workloads to remain on-premises while utilizing public cloud resources for scalability and cost-efficiency. Combining IaaS and PaaS addresses the need for scalable infrastructure and a development platform for custom applications. Adding SaaS in Option 4 offers ready-to-use software solutions, making it a more comprehensive choice for fulfilling all business requirements.
- A. Correct.
Correct: A hybrid cloud deployment allows the company to keep sensitive workloads on-premises while leveraging public cloud resources for scalability, and combining IaaS and PaaS provides the infrastructure and development platform required for custom applications.
- B. Incorrect.
Partially correct but not ideal: Public cloud deployment with SaaS and PaaS does not address the requirement to retain sensitive workloads on-premises, as public cloud is entirely off-premises.
- C. Incorrect.
Incorrect: Private cloud alone does not provide the scalability and cost-efficiency benefits of public cloud, and SaaS is not necessary for retaining sensitive workloads on-premises.
- D. Correct.
Correct: A hybrid cloud deployment with SaaS, PaaS, and IaaS offers a comprehensive solution. The hybrid model satisfies the compliance requirement for sensitive workloads, IaaS provides scalable infrastructure, PaaS supports custom application development, and SaaS provides pre-built software solutions.
- E. Incorrect.
Incorrect: Public cloud deployment with IaaS and SaaS does not align with the compliance requirement to retain sensitive workloads on-premises.
