This set of Software Project Management (SPM) Multiple Choice Questions & Answers (MCQs) focuses on Software Project Management Set 5

Q1 | How many phases are there in Scrum ?
  • two
  • three
  • four
  • scrum is an agile method which means it does not have phases
Answer: three
Explaination:
there are three phases in scrum.the initial phase is an outline planning phase followed by a series of sprint cycles and project closure phase.
Q2 | Which one of the following models is not suitable for accommodating any change?
  • build & fix model
  • prototyping model
  • rad model
  • waterfall model
Answer: waterfall model
Explaination:
real projects rarely follow the sequential flow that the waterfall model proposes.
Q3 | Incremental development in Extreme Programming (XP) is supported through a system release once every month.
  • true
  • false
Answer: false
Explaination:
incremental development is supported through small, frequent system releases.
Q4 | In XP, as soon as the work on a task is complete, it is integrated into the whole system.
  • true
  • false
Answer: true
Explaination:
xp follows a continuous integration approach.after any such integration, all the unit tests in the system must pass.
Q5 | In XP Increments are delivered to customers every                weeks.
  • one
  • two
  • three
  • four
Answer: two
Explaination:
extreme programming (xp) takes an ‘extreme’ approach to iterative development.new versions may be built
Q6 | Is a customer involved test development and validation in XP ?
  • yes
  • no
  • it may vary from customer to customer
  • none of the mentioned
Answer: it may vary from customer to customer
Explaination:
the role of the customer in the testing process is to help develop acceptance tests for the stories that are to be implemented in the next release of the system.however, people adopting the customer role have limited time available and so cannot work
Q7 | Programmers prefer programming to testing and sometimes they take shortcuts when writing tests. For example, they may write incomplete tests that do not check for all possible exceptions that may occur.
  • true
  • false
Answer: true
Explaination:
in xp some tests can be very difficult to write incrementally.for example, in a complex user interface, it is often difficult to write unit tests for the code that implements the ‘display logic’ and workflow between screens.
Q8 | Tests are automated in Extreme Programming.
  • true
  • false
Answer: true
Explaination:
automated test harnesses are used to run all component tests each time that a new release is built.
Q9 | In XP an automated unit test framework is used to write tests for a new piece of functionality before that functionality itself is implemented.
  • true
  • false
Answer: true
Explaination:
xp follows test-first development approach.
Q10 | Developers work individually on a release and they compare their results with other developers before forwarding that release to customers.
  • true
  • false
Answer: false
Explaination:
xp follows the principle of pair programming which means developers work in pairs, checking each other’s work and providing the support to always do a good job.
Q11 | Which four framework activities are found in the Extreme Programming(XP) ?
  • analysis, design, coding, testing
  • planning, analysis, design, coding
  • planning, design, coding, testing
  • planning, analysis, coding, testing
Answer: planning, design, coding, testing
Explaination:
xp involves the mentioned four activities, and in the same in order.
Q12 | Which process can be affected by other processes executing in the system?
  • cooperating process
  • child process
  • parent process
  • init process
Answer: cooperating process
Explaination:
none.
Q13 | When several processes access the same data concurrently and the outcome of the execution depends on the particular order in which the access takes place, is called?
  • dynamic condition
  • race condition
  • essential condition
  • critical condition
Answer: race condition
Explaination:
none.
Q14 | If a process is executing in its critical section, then no other processes can be executing in their critical section. This condition is called?
  • mutual exclusion
  • critical exclusion
  • synchronous exclusion
  • asynchronous exclusion
Answer: mutual exclusion
Explaination:
none.
Q15 | Which one of the following is a synchronization tool?
  • thread
  • pipe
  • semaphore
  • socket
Answer: semaphore
Explaination:
none.
Q16 | A semaphore is a shared integer variable
  • that can not drop below zero
  • that can not be more than zero
  • that can not drop below one
  • that can not be more than one
Answer: that can not drop below zero
Explaination:
none.
Q17 | Mutual exclusion can be provided by the
  • mutex locks
  • binary semaphores
  • both mutex locks and binary semaphores
  • none of the mentioned
Answer: both mutex locks and binary semaphores
Explaination:
binary semaphores are known as mutex locks.
Q18 | When high priority task is indirectly preempted by medium priority task effectively inverting the relative priority of the two tasks, the scenario is called
  • priority inversion
  • priority removal
  • priority exchange
  • priority modification
Answer: priority inversion
Explaination:
none.
Q19 | Process synchronization can be done on
  • hardware level
  • software level
  • both hardware and software level
  • none of the mentioned
Answer: both hardware and software level
Explaination:
none.
Q20 | 7 INTERACTIVE PROCESSES
  • shared data structures
  • procedures that operate on shared data structure
  • synchronization between concurrent procedure invocation
  • all of the mentioned
Answer: all of the mentioned
Explaination:
none.
Q21 | To enable a process to wait within the monitor                      
  • a condition variable must be declared as condition
  • condition variables must be used as boolean objects
  • semaphore must be used
  • all of the mentioned
Answer: a condition variable must be declared as condition
Explaination:
none.
Q22 | Which of the following are parameters involved in computing the total cost of a software development project?
  • hardware and software costs
  • effort costs
  • travel and training costs
  • all of the mentioned
Answer: all of the mentioned
Explaination:
all these are accounted for in estimating a software development cost.
Q23 | Which of the following costs is not part of the total effort cost?
  • costs of networking and communications
  • costs of providing heating and lighting office space
  • costs of lunch time food
  • costs of support staff
Answer: costs of lunch time food
Explaination:
this is a incurred by the employees.
Q24 | What is related to the overall functionality of the delivered software?
  • function-related metrics
  • product-related metrics
  • size-related metrics
  • none of the mentioned
Answer: function-related metrics
Explaination:
productivity is expressed in terms of the amount of useful functionality produced in some given time. function points and object points
Q25 | A                    is developed using historical cost information that relates some software metric to the project cost.
  • algorithmic cost modelling
  • expert judgement
  • estimation by analogy
  • parkinson’s law
Answer: algorithmic cost modelling
Explaination:
the model uses a basic regression formula with parameters that are derived from historical project data and current as well as future project characteristics.
