(Group 15) Distributed Systems

Which of these architectures is reliant on middle-ware?

• Multi-tier

  Client–Server Architecture

• Master-Slave Architecture

• Distributed Component Architecture

• Peer-to-Peer Architecture

Which of these is a decentralized architecture in which

there are no distinguished clients and servers?

• Multi-tier

  Client–Server Architecture

• Master-Slave Architecture

• Distributed Component Architecture

• Peer-to-Peer Architecture

Which of the following is not true about a Peer-to-Peer architecture?

• Fault-tolerant and tolerant of computers disconnecting from the network

• Easy to centrally back up data stored in the system

• Highly redundant

• Difficult to manage

What are the key elements of SaaS?

• Software is deployed on the server

• Software is owned and managed by a software provider

• Software usage may be subscription based or free for anyone

• All of the above

Which of these is not part of the three important

implementation factors for SaaS?

• Configurability

• Flexibility

• Multi-tenancy

• Scalability

Which of these is not a benefit of SaaS?

• Data Transfer

• Software license management costs are zero

• Accessibility

• Software managment costs are transferred to the provider

Which of the following is not a logical layer of a system?

• Data management

• Presentation

• Processing

• Verification

This architecture is commonly used for real-time systems

• Master-Slave architecture

• Two-tier architecture

• Distributed Component architecture

• Peer-to-Peer architecture

In a fat-client model, the application processing is done on the server

• True

• False

For communications between components to occur,

should their physical locations matter?

• Yes. Long signal travel distances degrade the overall experience

• No. If all the components work, then the system should work as well

• No. It is the job of the middleware to facilitate communication

• Yes. Long distance configurations are hard to maintain and test
