This set of Software Project Management (SPM) Multiple Choice Questions & Answers (MCQs) focuses on Software Project Management Set 9

Q1 | A PERT network is activity-oriented while a CPM network is event-oriented.
  • true
  • false
Answer: false
Explaination:
a cpm network is activity- oriented while a pert network is event- oriented. event is the completion of an activity or the commencement of an activity. an event may be head event, tail event or dual role event.
Q2 |                    are used to represent activity in a network diagram.
  • circles
  • squares
  • rectangles
  • arrows
Answer: arrows
Explaination:
a network is a flow diagram that consists of events and activities which are connected sequentially and logically.
Q3 | The shortest possible time in which an activity can be achieved under ideal circumstances is known as                  
  • pessimistic time estimate
  • optimistic time estimate
  • expected time estimate
  • the most likely time estimate
Answer: optimistic time estimate
Explaination:
there are three kinds of time estimates made by pert planners. these are the optimistic time estimate, the pessimistic time estimate and the most likely time estimate. the shortest possible time in which an activity can be achieved under ideal circumstances is known as the optimistic time estimate.
Q4 | According to the time estimates made by the PERT planners, the maximum time that would be needed to complete an activity is called as                      
  • the most likely time estimate
  • optimistic time estimate
  • pessimistic time estimate
  • expected time estimate
Answer: pessimistic time estimate
Explaination:
according to the time estimates made by the pert planners, the maximum time that would be needed to complete an activity is called the pessimistic time estimate. this estimate does not include possible effects of floods, earthquakes, etc.
Q5 | In a network, a critical path is the time- wise shortest path.
  • true
  • false
Answer: false
Explaination:
in a network, a critical path is the time-wise longest path. the critical path in the critical path method plays an essential role in scheduling and planning.
Q6 | The difference between the maximum time available and the actual time needed to perform an activity is known as                    
  • free float
  • independent float
  • total float
  • half float
Answer: total float
Explaination:
the difference between the maximum time available and the actual time needed to perform an activity is known as the total float. hence, the total float is the excess of the maximum available time throughout the time of the activity.
Q7 | A randomized algorithm uses random bits as input inorder to achieve a                             good performance over all possible choice of random bits.
  • worst case
  • best case
  • average case
  • none of the mentioned
Answer: average case
Explaination:
a randomized algorithm is an algorithm that employs a degree of randomness as a part of its logic using random bits as inputs and in hope of producing average case good performace.
Q8 | Which of the following are probalistic algorithms?
  • las vegas algorithm
  • monte carlo algorithm
  • atlantic city algorithm
  • all of the mentioned
Answer: all of the mentioned
Explaination:
monte carlo algorithms are very vast, but only probably correct. on thr other side, las vegas algorithms are always correct, but probably fast.
Q9 | Which of the following algorithms are probably correct as well as fast?
  • las vegas algorithm
  • monte carlo algorithm
  • atlantic city algorithm
  • all of the mentioned
Answer: atlantic city algorithm
Explaination:
the atlantic city algorithms which are bounded polynomial time algorithms are probably correct and probably fast. it is correct more than 75% of the times.
Q10 | Prisonner’s dilemma can be related to the following:
  • cooperative behaviour
  • graph theory
  • both (a) and (b)
  • none of the mentioned
Answer: cooperative behaviour
Explaination:
prisonner’s dilemma is a standard example of a game analysed in game theory where rational cooperative behaviour is judged on the basis of rewards and punishment.
Q11 | Unix sort command uses                    as its sorting technique.
  • quick sort
  • bucket sort
  • radix sort
  • merge sort
Answer: quick sort
Explaination:
quicksort is the method of choice in many applications( unix sort command) with o(nlogn) in worst case.
Q12 | Which of the following can be solved in computer science?
  • p=bpp problem
  • np=co-np problem
  • do one way problems exist?
  • all of the mentioned
Answer: all of the mentioned
Explaination:
there exists a list of unsolved problems in computational theory which includes many problems including the ones given.
Q13 | Which of the following can be referred to as applications of Randomized algorithm?
  • quicksort
  • min cut
  • verifying matrix multiplication
  • all of the mentioned
Answer: all of the mentioned
Explaination:
freivalds algorithm is a probabalistic randomized algorithm we use to verify matrix multiplication. on the other hand, randomness can be useful in quicksort. if the algorithm selects pivot element uniformaly at random, it has a probably high probabilty of finishing the work in o(nlogn) time regardless of the input.
Q14 | What is the popular method of organizing wireless network topologies?
  • software
  • synchronization
  • network
  • cluster
Answer: cluster
Explaination:
clustering is a popular method of organising wireless network topologies, in which a few nodes, the cluster heads are elected as representing to route the traffic originated in the entire network.
Q15 |                    will enable the humans to access, control and manage the operation.
  • iot
  • bigdata
  • network
  • communication
Answer: iot
Explaination:
iot enables the humans to access, control and manage the operations
Q16 | In                    the embedded devices and objects working under IoT are resource constrained.
  • health
  • industry
  • home
  • information system
Answer: information system
Explaination:
in the information system the embedded devices and objects working under iot implementation are resource constrained.
Q17 | What type of networks is interacting under IoT?
  • heterogeneous only
  • homogeneous only
  • both hetero and homogeneous
  • neither hetero nor homo
Answer: heterogeneous only
Explaination:
due to the huge number of heterogeneous network elements interacting and working under iot based information systems, there is an enormous need for resource management for the smooth running of iot operations.
