Q1 | A web cookie is a small piece of data that is
  • sent from a website and stored in user’s web browser while a user is browsing a website
  • sent from user and stored in the server while a user is browsing a website
  • sent from root server to all servers
  • sent from the root server to other root servers
Answer: sent from a website and stored in user’s web browser while a user is browsing a website
Explaination:
a web cookie is a small piece of data sent from a website and stored in user’s web browser while a user is browsing the website and is used to remember stateful information about the user’s operations on the website. this can help the website provide a better browsing experience to the user.
Q2 | Which one of the following is not used to generate dynamic web pages?

Answer: cluster
Explaination:
in a computer cluster all the participating computers work together on a particular task.
Q5 | What is document object model (DOM)?
  • convention for representing and interacting with objects in html documents
  • application programming interface
  • hierarchy of objects in asp.net
  • scripting language
Answer: convention for representing and interacting with objects in html documents
Explaination:
dom is a hierarchical model i.e. a tree used to represent an html or xml document. every node of the tree an object that represents a part of the document.
Q6 | AJAX stands for                
  • asynchronous javascript and xml
  • advanced jsp and xml
  • asynchronous jsp and xml
  • advanced javascript and xml
Answer: asynchronous javascript and xml
Explaination:
ajax is a group of technologies that works on the client-side to create asynchronous web applications. it is used to modify only a part of a webpage and not the whole webpage whenever some event occurs.
Q7 | TOPIC 4.2 SEARCH ENGINE ARCHITECTURES
  • utp
  • rj-45
  • stp
  • coaxial cable
Answer: rj-45
Explaination:
the computers are connected to each other using a lan connector cable.
Q8 | The computer cluster architecture emerged as a result of                    
  • isa
  • workstation
  • super computers
  • distributed systems
Answer: distributed systems
Explaination:
a distributed system is a computer system spread out over a geographic area.
Q9 | The software which governs the group of computers is                      
  • driver rd45
  • interface ui
  • clustering middleware
  • distributor
Answer: clustering middleware
Explaination:
the software helps to project a single system image to the user.
Q10 | approach.
  • beowolf
  • sequoia
  • stone
  • none of the mentioned
Answer: beowolf
Explaination:
none.
Q11 | The cluster formation in which the work is divided equally among the systems is              
  • load-configuration
  • load-division
  • light head
  • both load-configuration and load-division
Answer: load-configuration
Explaination:
this approach the work gets divided among the systems equally.
Q12 |                    approach is used.
  • load configuration
  • fifo
  • bankers algorithm
  • round robin
Answer: round robin
Explaination:
by using this approach the performance of the cluster can be enhanced.
Q13 |                      approach of a relationship between the systems.
  • master-slave
  • asynchronous
  • synchronous
  • isochronous
Answer: master-slave
Explaination:
none.
Q14 | The most common modes of communication in clusters are              
  • message queues
  • message passing interface
  • pvm
  • both message passing interface and pvm
Answer: both message passing interface and pvm
Explaination:
none.
Q15 | The method followed in case of node failure, wherein the node gets disabled is
  • stonith
  • fibre channel
  • fencing
  • none of the mentioned
Answer: stonith
Explaination:
none.
Q16 | Which of the following term is best defined by the statement “In a distributed system, several processes may operate at the same time on separate computers on the network.”?
  • concurrency
  • openness
  • resource sharing
  • fault tolerance
Answer: concurrency
Explaination:
none.
Q17 | Which of the following is not a dimension of scalability?
  • size
  • distribution
  • manageability
  • interception
Answer: interception
Explaination:
interception is a communication conception.
Q18 | A distributed system must defend itself against
  • modification
  • interruption
  • fabrication
  • all of the mentioned
Answer: all of the mentioned
Explaination:
none.
Q19 | QoS stands for
  • quality of security
  • quality of system
  • quality of service
  • none of the mentioned
Answer: quality of service
Explaination:
qos is particularly critical when the system is dealing with time-critical data such as sound or video streams.
Q20 | though not identical to, RPCs.
  • remote method invocations
  • operating system
  • client–server computing
  • none of the mentioned
Answer: remote method invocations
Explaination:
the rmi framework handles the invocation of remote methods in a java program.
Q21 |                     depend on there being a clear separation between the presentation of information and the computations that create and process that information.
  • master-slave architectures
  • client–server systems
  • two-tier client–server architecture
  • both master-slave architectures and client–server systems
Answer: client–server systems
Explaination:
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.
