2. _____________ is a technique, which allows to share single physical instance of an application or resource among multiple organizations or tenants (customers).
A. Virtualization
B. Service-Oriented Architecture
C. Grid Computing
D. Utility Computing
View Answer
Ans : A
Explanation: Virtualization is a technique, which allows to share single physical instance of an application or resource among multiple organizations or tenants (customers)
3. What is true about Virtualization?
A. In Virtualization, it is necessary to have well-compiled Multitenant.
B. In Virtualization, we analyze the strategy problems that customer might face
C. It assign a logical name to a physical resource and providing a pointer to that physical resource when demanded.
D. All of the above
View Answer
Ans : C
Explanation: It assign a logical name to a physical resource and providing a pointer to that physical resource when demanded is true regarding Virtualization.
4. In Virtualization, Which architecture offers virtual isolation among the multiple tenants?
A. IT Architecture
B. Multitenant
C. Deployment
D. Business Architecture
View Answer
Ans : B
Explanation: The Multitenant architecture offers virtual isolation among the multiple tenants. Hence, the organizations can use and customize their application as though they each have their instances running.
5. Utility computing is based on?
A. Grid Computing Model
B. Pay-per-Use model
C. virtual isolation Model
D. SOA Model
View Answer
Ans : B
Explanation: Utility computing is based on Pay-per-Use model.
6. What is true about Service-Oriented Architecture?
A. Service-Oriented Architecture helps to use applications as a service for other applications
B. It is possible to exchange the data between applications of different vendors without additional programming
C. It offers computational resources on demand as a metered service.
D. Both A and B
View Answer
Ans : D
Explanation: Service-Oriented Architecture helps to use applications as a service for other applications regardless the type of vendor, product or technology. Therefore, it is possible to exchange the data between applications of different vendors without additional programming or making changes to services.
7. In Grid Computing, computer resources are?
A. heterogeneous dispersed.
B. geographically dispersed.
C. Both A and B
D. None of the above
View Answer
Ans : C
Explanation: These computer resources are heterogeneous and geographically dispersed.
8. Managed IT services are based on the concept of?
A. Virtualization
B. SOA
C. Grid Computing
D. Utility Computing
View Answer
Ans : D
Explanation: Cloud computing, grid computing, and managed IT services are based on the concept of utility computing.

A. Virtualization
B. SOA
C. Grid Computing
D. Utility Computing
View Answer
Ans : C
Explanation: Grid Computing refers to distributed computing, in which a group of computers from multiple locations are connected with each other to achieve a common objective.
10. What is true about Grid Computing?
A. breaks complex task into smaller pieces
B. combine smaller task into complex task
C. subscription tier play vital role in Grid Computing
D. Both A and B
View Answer
Ans : A
