1. Which of the following is one of the properties that differentiates cloud computing?
a) scalability
b) virtualization
c) composability
d) all of the mentioned
Explanation: Composability is the ability to build applications from component parts.
2. Point out the correct statement.
a) Cloud computing is a natural extension of many of the design principles, protocols, plumbing, and systems
b) Platforms are used to create more easy software
c) All SLAs are enforceable as contracts
d) All of the mentioned
Explanation: Cloud computing describes some new capabilities that are architected into an application stack and are responsible for the programmability, scalability, and virtualization of resources.
3. A _________ is a cloud computing service that is both hardware and software.
a) service
b) platform
c) model
d) All of the mentioned
Explanation: Virtual appliances are an important example of a platform.
4. Cloud computing doesn’t require that ________ and software be composable.
a) cloud
b) database
c) hardware
d) All of the mentioned
Explanation: It is a highly desirable characteristic from a developer or user’s standpoint.
5. Point out the wrong statement.
a) Virtual appliances are becoming a very important standard cloud computing deployment object
b) Cloud computing requires some standard protocols
c) Cloud computing relies on a set of protocols needed to manage interprocess communications
d) None of the mentioned
Explanation: Many of these protocols are standard Internet protocols.
6. The most commonly used set of protocols uses ______ as the messaging format.
a) XML
b) JSON
c) BSON
d) All of the mentioned
Explanation: Cloud computing builds on the architecture developed for staging large distributed network applications on the Internet.
7. Which of the following language is used to manage transactions?
a) WSDL
b) XML
c) SOAP
d) all of the mentioned
Explanation: WSDL is an XML format for describing network services as a set of endpoints operating on messages containing either document-oriented or procedure-oriented information.
8. Which of the architectural layer is used as backend in cloud computing?
a) client
b) cloud
c) soft
d) All of the mentioned
Explanation: The cloud creates a system where resources can be pooled and partitioned as needed.
9. A ________ cloud requires virtualized storage to support the staging and storage of data.
a) soft
b) compute
c) local
d) none of the mentioned
Explanation: From a user’s perspective, it is important that the resources appear to be infinitely scalable, that the service be measurable, and that the pricing is metered.
10. A _______ system uses components to assemble services that can be tailored for a specific purpose using standard parts.
a) reliable
b) scalable
c) composable
d) none of the mentioned
Explanation: Applications built in the cloud often have the property of being built from a collection of components, a feature referred to as composability.
