Software Questions

1. A software project involves execution of 5 tasks T1, T2, T3, T4 and T5 of duration 10, 15, 18, 30 and 40 days, respectively. T2 and T4 can start only after T1 completes. T3 can start after T2 completes. T5 can start only after both T3 and T4 complete. What is the slack time of the task T3 in days?

Correct Ans:0

2. A software organization has been assessed at SEI CMM Level 4. Which of the following does the organization need to practice beside Process Change Management and Technology Change Management in order to achieve Level 5?

Correct Ans:Defect Prevention

3. In a software project, COCOMO (Constructive Cost Model) is used to estimate

Correct Ans:effort and duration based on the size of the software

4. Consider a software program that is artificially seeded with 100 faults. While testing this program, 159 faults are detected, out of which 75 faults are from those artificially seeded faults. Assuming that both real and seeded faults are of same nature and have same distribution, the estimated number of undetected real faults is ____________.

Correct Ans:28
Total faults detected = 159
Real faults detected among all detected faults = 159 - 75
= 84
Since probability distribution is same, total number of real faults is (100/75)*84 = 112

Undetected real faults = 112- 84 = 28

5. A Software Requirements Specification (SRS) document should avoid discussing which one of the following?

Correct Ans:Design specification

6. Consider the following C program segment.
while (first <= last)
if (array [middle] < search)
first = middle +1;
else if (array [middle] == search)
found = True;
else last = middle ??? 1;
middle = (first + last)/2;
if (first < last) not Present = True;

The cyclomatic complexity of the program segment is __________.

Correct Ans:5

7. Match the following
List-I -------- List-II
A. Condition coverage -------- 1. Black-box testing
B. Equivalence class partitioning -------- 2. System testing
C. Volume testing -------- 3. White-box testing
D. Alpha testing -------- 4. Performance testing

(a) 2 3 1 4
(b) 3 4 2 1
(c) 3 1 4 2
(d) 3 1 2 4

Correct Ans:c

8. In the context of modular software design, which one of the following combinations is desirable?

Correct Ans:High cohesion and low coupling

9. Match the following:
1) Waterfall model --------- a) Specifications can be developed incrementally
2) Evolutionary model --------- b) Requirements compromises are inevitable
3) Component-based --------- c) Explicit recognition of risk software engineering
4) Spiral development --------- d) Inflexible partitioning of the project into stages

Correct Ans:1-d, 2-a, 3-b, 4-c
Waterfall Model: We can not go back in previous project phase as soon as as we proceed to next phase ,So inflexible

Evolutionary: It keeps changing with evolution so incremental in nature

Component based: Reuse-based approach to defining, implementing and composing loosely coupled independent components into systems

Spiral: Spiral model is the most advanced .It includes four faces one of which is Risk.
Phases: Planning, Risk Analysis, Engineering and Evaluation

10. Consider the following statements about the cyclomatic complexity of the control flow graph of a program module. Which of these are TRUE?

I. The cyclomatic complexity of a module is equal to the maximum number of linearly independent circuits in the graph.
II. The cyclomatic complexity of a module is the number of decisions in the module plus one,where a decision is effectively any conditional statement in the module.
III.The cyclomatic complexity can also be used as a number of linearly independent paths that should be tested during path coverage testing.

Correct Ans:II and III

11. The coupling between different modules of a software is categorized as follows:
I. Content coupling
II. Common coupling
III. Control coupling
IV. Stamp coupling
V. Data coupling
Coupling between modules can be ranked in the order of strongest (least desirable) to weakest (most desirable) as follows:

Correct Ans:I-II-III-IV-V

12. The following program is to be tested for statement coverage:
if (a== b) {S1; exit;}
else if (c== d) {S2;]
else {S3; exit;}

The test cases T1, T2, T3 and T4 given below are expressed in terms of the properties satisfied by the values of variables a, b, c and d. The exact values are not given. T1 : a, b, c and d are all equal T2 : a, b, c and d are all distinct T3 : a = b and c != d T4 : a != b and c = d Which of the test suites given below ensures coverage of statements S1, S2, S3 and S4?

Correct Ans:T1, T2, T4
T1 checks S1

T2 checks S3

T4 checks S2 and S4

13. What is the appropriate pairing of items in the two columns listing various activities encountered in a software life cycle?

P. Requirements Capture --------- 1.Module Development and Integration
Q. Design --------- 2.Domain Analysis
R. Implementation --------- 3.Structural and Behavioral Modeling
S. Maintenance --------- 4.Performance Tuning

Correct Ans:P-2, Q-3, R-1, S-4

14. Which one of the following is NOT desired in a good Software Requirement Specifications (SRS) document?

Correct Ans:Algorithms for Software Implementation

15. A company needs to develop digital signal processing software for one of its newest inventions. The software is expected to have 40000 lines of code. The company needs to determine the effort in person-months needed to develop this software using the basic COCOMO model. The multiplicative factor for this model is given as 2.8 for the software development on embedded systems, while the exponentiation factor is given as 1.20. What is the estimated effort in person-months?

Correct Ans:234.25
In the Constructive Cost Model (COCOMO), following is formula for effort applied
Effort Applied (E) = ab(KLOC)^bb [ person-months ]
= 2.8 x(40)1.20
= 2.8 x 83.65
= 234.25

16. Match the problem domains in GROUP I with the solution technologies in GROUP II

(P) Service oriented computing ---------- (1) Interoperability
(Q) Heterogeneous communicating systems ---------- (2) BPMN
(R) Information representation ---------- (3) Publish-find-bind
(S) Process description ---------- (4) XML

Correct Ans:P-3, Q-1, R-4, S-2

Correct Ans:Driver

18. Which of the following is not a static testing technique
