File systems are normally shared in a cluster computing and cloud computing environment.
- C.
File systems are normally shared in a cluster computing environment but not in cloud computing environment.
- D.
File systems are normally shared in a cloud computing environment but not in a cluster computing environment.
Correct Answer
C. File systems are normally shared in a cluster computing environment but not in cloud computing environment.Explanation
In cluster computing environments, file systems are typically shared among multiple nodes to allow for efficient data access and processing. This is because cluster computing involves a group of interconnected computers working together on a common task. On the other hand, in cloud computing environments, file systems are not typically shared as the focus is more on providing scalable and on-demand access to computing resources through virtualization. Cloud computing often involves multiple users accessing their own isolated virtual machines or containers, rather than sharing a common file system.Rate this question:

When implementing a cloud computing environment, which scenario should be considered first?
- A.
An area where the approval process is complex.
- B.
An area where the approval process can be automated.
- C.
. An area where most of the approval can be delegated.
- D.
An area where there is no documented approval process.
Correct Answer
B. An area where the approval process can be automated.Explanation
When implementing a cloud computing environment, it is important to consider an area where the approval process can be automated first. Automating the approval process in this area will help streamline and expedite the overall implementation process. It will also reduce the need for manual intervention and improve efficiency. Additionally, automating the approval process can help ensure consistency and accuracy in the decision-making process. Therefore, focusing on an area where the approval process can be automated is a logical and practical approach to implementing a cloud computing environment.Rate this question:

How is a business approval process related to a cloud computing environment?
- A.
A cloud computing environment requires an expedited business approval process.
- B.
A business approval process is required to deploy a cloud computing environment
- C.
A cloud computing environment can be implemented without a business approval process.
- D.
. A business approval process must be documented before implementing a cloud computing environment.
Correct Answer
D. . A business approval process must be documented before implementing a cloud computing environment.Explanation
In order to implement a cloud computing environment, it is necessary to have a business approval process documented. This process ensures that the deployment of the cloud environment aligns with the goals and requirements of the business. It allows for proper evaluation, decision-making, and authorization before the implementation takes place. Without a business approval process, there may be a lack of clarity and control over the implementation, leading to potential issues and conflicts.Rate this question:

Why is a defined approval process important for a cloud computing implementation?
- A.
It defines the access to a cloud computing resource.
- B.
It defines the responsibilities for the cloud computing environment
- C.
It defines the authorization process for cloud computing provisioning.
- D.
It defines the authorization process for a cloud computing implementation.
Correct Answer
C. It defines the authorization process for cloud computing provisioning.Explanation
A defined approval process is important for a cloud computing implementation because it establishes the authorization process for cloud computing provisioning. This ensures that only authorized individuals or entities can access and provision cloud computing resources. By defining the approval process, organizations can maintain control over their cloud environment, prevent unauthorized access or provisioning, and ensure that resources are allocated efficiently and securely. Without a defined approval process, there is a higher risk of security breaches, resource misuse, and inefficient resource allocation.Rate this question:

- A.
Create a virtualized server infrastructure.
- B.
Create a virtualized application infrastructure.
- C.
Create a virtualized information infrastructure.
- D.
Create a virtualized end user / client infrastructure.
Correct Answer
C. Create a virtualized information infrastructure.Explanation
By creating a virtualized information infrastructure, the company can leverage its data to generate business value. This infrastructure allows for efficient storage, management, and protection of data, enabling the company to easily access and analyze the information. With the ability to extract insights and make data-driven decisions, the company can optimize its operations, improve customer experiences, and identify new opportunities for growth. Additionally, a virtualized information infrastructure enables scalability and flexibility, allowing the company to adapt to changing business needs and stay competitive in the market.Rate this question:

In cloud computing, which term is used to describe the nature of IT infrastructure and allows dynamic scaling depending on the demand for resources?
- A.
elasticity
- B.
Clustering
- C.
Consolidation
- D.
virtualization
Correct Answer
A. elasticityExplanation
Elasticity is the term used in cloud computing to describe the nature of IT infrastructure that allows for dynamic scaling based on the demand for resources. This means that the system can automatically adjust its capacity to handle increased or decreased workload, ensuring that the necessary resources are available when needed and avoiding unnecessary resource allocation during periods of low demand. This flexibility is a key characteristic of cloud computing, allowing businesses to efficiently manage their IT infrastructure and optimize resource utilization.Rate this question:

A company has peak customer demand for its IT services in the month of April. It has enough IT resources to handle off peak demand but not peak load. What is the best approach to handle this situation?
- A.
Outsource all of IT services to a cloud based provider.
- B.
Virtualize its servers and implement a cloud based system.
- C.
Utilize an external cloud service provider to handle the peak load.
- D.
Acquire additional IT resources and design the system to handle the peak load.
Correct Answer
C. Utilize an external cloud service provider to handle the peak load.Explanation
The best approach to handle the situation of peak customer demand in April when the company does not have enough IT resources is to utilize an external cloud service provider. By doing so, the company can offload the peak load to the cloud service provider, who can provide the necessary resources to handle the increased demand. This allows the company to scale up its IT services temporarily without the need to acquire additional resources or invest in server virtualization.Rate this question:
