• 1. It is the process of sharing license keys between various enterprise users

     to physical instances of application.

• 1. The process is based on the concept of pay-per-use.

In which of the following, users may want to use resources before scaling out onto a public cloud, and they may have a choice for a particular cloud or may require to combine different clouds?

• Community Cloud

• Private Cloud

• Hybrid Cloud

• None of the above

• 1. Resource Pool

• 1. Resource Provisioning Service

• 1. Resource Pool Manager

The physical machine is also known as the _________, which receives the incoming requests and distributes those requests for further execution to various physical machines.

• 1. Framework Agreement

• 1. Service Application

• 1. Front-end Node

• 1. Federated Cloud Computing Architecture

Is the following statement true or false?

Which of the following statement is correct regarding the Negotiation?

• 1. Service providers usually describe a set of service offerings and related

     SLAs using standard templates.

• 1. The terms and conditions of the SLA must be mutually agreed before

As per workflow management systems and clouds, what is Elasticity?

• 1. This helps workflow management systems to readily meet users '

     Quality of Service (QoS) criteria, as opposed to the traditional approach that required advance reservation of resources in global multi-user grid environments.

• 1. It allows workflow management systems to provide greater end-to-end guarantees while meeting with customer's service requirements by mapping them to service providers based on SLAs characteristics.

• 1. The reduced need to secure the physical resource from malicious code is one of the advantages of using virtualised resources for workflow execution, as opposed to having direct access to the physical machine.

• 1. These provide a higher level of growth and runtime environment for the building and deploying of cloud infrastructure workflow applications.
