c) Resource sharing
d) Fault tolerance
View Answer
Explanation: None.
2. Which of the following is not a dimension of scalability?
a) Size
b) Distribution
c) Manageability
d) Interception
View Answer
Explanation: Interception is a communication conception.
3. A distributed system must defend itself against
a) Modification
b) Interruption
c) Fabrication
d) All of the mentioned
View Answer
Explanation: None.
4. QoS stands for
a) Quality of security
b) Quality of system
c) Quality of service
d) None of the mentioned
View Answer
Explanation: QoS is particularly critical when the system is dealing with time-critical data such as sound or video streams.
5. In Java,_________ are comparable with, though not identical to, RPCs.
a) Remote Method Invocations
b) Operating System
c) Client–server computing
d) None of the mentioned
View Answer
Explanation: The RMI framework handles the invocation of remote methods in a Java program.
6. _________ depend on there being a clear separation between the presentation of information and the computations that create and process that information.
a) Master-slave architectures
b) Client–server systems
c) Two-tier client–server architecture
d) Both Master-slave architectures AND Client–server systems
View Answer
Explanation: One should design the architecture of distributed client–server systems so that they are structured into several logical layers, with clear interfaces between these layers.
7. Which architecture is used when there is a high volume of transactions to be processed by the server?
a) Multi-tier client–server architecture
b) Master-slave architecture
c) Distributed component architecture
d) Peer-to-peer architecture
View Answer
Explanation: Multi-tier systems may be used when applications need to access and use data from different databases.
8. Which architecture are reliant on middle-ware?
a) Multi-tier client–server architecture
b) Master-slave architecture
c) Distributed component architecture
d) Peer-to-peer architecture
View Answer
Explanation: It allows the system designer to delay decisions on where and how services should be provided.
9. __________ is a way of providing functionality on a remote server with client access through a web browser.
a) SaaS
b) SOA
c) Configurability
d) Both SaaS and Configurability
View Answer
Explanation: The server maintains the user’s data and state during an interaction session.
10. Which architecture decentralized architectures in which there are no distinguished clients and servers?
a) Multi-tier client–server architecture
b) Master-slave architecture
c) Distributed component architecture
d) Peer-to-peer architecture
View Answer
Explanation: Peer-to-peer (p2p) systems are decentralized systems in which computations may be carried out by any node on the network.
