A. B. C. D.Correct Answer: D.
Option A is Incorrect, as in the given scenario IaaS is a good choice, and hence the given statement is correct.
IaaS can be used to Run testing and development.
Option B is Incorrect, as in the given scenario IaaS is a good choice, and hence the given statement is correct.
IaaS can be used to Perform big data analysis.
Option C is Incorrect, as in the given scenario IaaS is a good choice, and hence the given statement is correct.
IaaS can be used to Improve disaster recovery preparation.
Option D is Correct, as in the given scenario/statement is incorrect.
While using IaaS the customer has control over theOperating System hosting your application.
In PaaS and SaaS, the customer does not have control over the Operating System hosting the application.
Reference:
https://cloud.google.com/learn/what-is-iaas#section-5IaaS or Infrastructure as a Service is a cloud computing model where third-party providers offer virtualized computing resources over the internet. The IaaS model allows businesses to avoid the expense and complexity of purchasing and managing physical servers, storage, and networking infrastructure. Instead, they can rent these resources from a cloud provider on a pay-as-you-go basis.
Now, coming to the given options, let's understand each scenario:
A. IaaS cannot be used to Run testing and development: This statement is incorrect as IaaS can be an excellent option for running testing and development. It allows businesses to quickly provision and deprovision virtual machines and other resources to build and test their applications. Also, IaaS can provide a cost-effective way to create multiple testing environments that mirror production environments.
B. IaaS cannot be used to Perform big data analysis: This statement is also incorrect as IaaS can be used for performing big data analysis. With IaaS, businesses can easily scale up or down their compute and storage resources as needed to handle the data processing requirements of big data applications. Also, many IaaS providers offer specialized big data tools and services that can make data processing and analysis more efficient.
C. IaaS cannot be used to Improve disaster recovery preparation: This statement is incorrect as IaaS can be an excellent option for disaster recovery preparation. By using IaaS, businesses can replicate their applications and data across multiple geographic regions to ensure that they can quickly recover from any outages or disasters. Additionally, IaaS providers often offer built-in backup and recovery services, making disaster recovery preparation more accessible and cost-effective.
D. IaaS cannot be used to get Improved control on Operating System hosting your application: This statement is correct. IaaS providers typically offer virtualized servers with a pre-configured operating system. While businesses can customize their applications and other software running on these servers, they may not have complete control over the underlying operating system. If a business needs complete control over the operating system hosting its application, it may need to consider other cloud computing models such as PaaS (Platform as a Service) or on-premises infrastructure.
In conclusion, the correct answer to this question is (D) IaaS cannot be used to get Improved control on Operating System hosting your application.
