A. Defined
B. Optimizing
C. Initial
D. Managed
E. Repeatable
Choose the correct answer from the options given below:
Solution
$1.$ Initial
$2.$ Repeatable
$3.$ Defined
$4.$ Managed
$5.$ Optimizing
Now match with the given letters:
Initial $=C$
Repeatable $=E$
Defined $=A$
Managed $=D$
Optimizing $=B$
So, the correct order is:
$C,E,A,D,B$
Statement I: Cleanroom software process model incorporates the statistical quality certification of code increments as they accumulate into a system.
Statement II: Cleanroom software engineering follows the classic analysis, design, code, test, and debug cycle to software development and focussing on defect removal rather than defect prevention.
In light of the above statements, choose the correct answer from the options given below.
Solution
Statement I is correct because Cleanroom model uses statistical quality certification of software increments.
Statement II is incorrect because Cleanroom does not follow the classic test and debug cycle in the usual way.
It emphasizes formal methods, correctness verification and statistical testing, with focus on preventing defects.
Therefore, Statement I is true and Statement II is false.
Assertion A: Software developers do not do exhaustive software testing in practice.
Reason R: Even for small inputs, exhaustive testing is too computationally intensive, that is, takes too long to run all the tests.
In light of the above statements, choose the correct answer from the options given below.
Solution
In practice, exhaustive testing is not possible because the number of test cases becomes very large.
Even for small programs, all possible input combinations may take too much time and computation.
So, Assertion A is true.
Reason R is also true because it correctly explains why exhaustive testing is not done in practice.
Solution
Typical Software Development Life Cycle (SDLC) activities:
-
Requirement Analysis ✔
-
System Design ✔
-
Implementation / Testing
-
Deployment ✔
Check options:
(A) Requirement Analysis → ✔
(B) System Design → ✔
(C) Code Refactoring → maintenance activity, not core lifecycle step ✘
(D) Deployment → ✔
(E) Substructure → not SDLC activity ✘
Thus correct:
(A), (B), (D)
Solution
In incremental model, software is developed and delivered in small parts called increments.
First, a working core product is developed quickly.
Then, more features are added step by step.
So, correct option is:
$\boxed{(b)\ \text{A good approach when a working core product is required quickly}}$
Solution
Typical Agile workflow:
Planning
Design
Development
Testing
Release
Thus order:
(E) → (A) → (D) → (C) → (B)
| List-I | Attribute | List-II | Definition |
|---|---|---|---|
| (a) | Functionality | (i) | Relationship between level of performance and amount of resources |
| (b) | Reliability | (ii) | Characteristics related with achievement of purpose |
| (c) | Efficiency | (iii) | Efforts needed to make for improvement |
| (d) | Maintainability | (iv) | Capability of software to maintain performance of software |
Solution
Functionality means characteristics related with achievement of purpose.
So, (a) $\rightarrow$ (ii)
Reliability means capability of software to maintain its performance.
So, (b) $\rightarrow$ (iv)
Efficiency means relationship between level of performance and amount of resources used.
So, (c) $\rightarrow$ (i)
Maintainability means efforts needed to make improvement.
So, (d) $\rightarrow$ (iii)
Hence, correct matching is:
(a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)
| List-I | Agile Process Model | List-II | Task |
|---|---|---|---|
| (a) | Scrum | (i) | CRC cards |
| (b) | Adaptive software development | (ii) | Sprint backlog |
| (c) | Extreme programming | (iii) | the <by/for/of/to> a(n) |
| (d) | Feature-driven development | (iv) | Time box release plan |
Solution
Scrum uses sprint backlog.
So, (a) $\rightarrow$ (ii)
Adaptive Software Development uses time box release plan.
So, (b) $\rightarrow$ (iv)
Extreme Programming uses CRC cards.
So, (c) $\rightarrow$ (i)
Feature-Driven Development uses feature template like:
the <by/for/of/to> a(n)
So, (d) $\rightarrow$ (iii)
Hence, correct matching is:
(a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)
If a software project has 2000 lines of code (LOC) and the average productivity rate is 10 LOC per person-hour, how many person-hours are required to complete the project?
Solution
The primary objectives of the SWE-IPT are to:
A. Solicit stakeholder needs and expectations.
B. Specify the software requirements for the product and post-development processes.
C. Generate the integrated technical plans for accomplishing the software development effort.
D. Translate stakeholder requirements into a complete, specified architectural description.
E. Ensure that the software technical data package is sufficiently detailed to facilitate an efficient and effective software implementation.
Choose the correct answer from the options given below:
Solution
SWE-IPT means Software Engineering Integrated Product Team.
Its objectives include requirement collection, software requirement specification, planning, architectural description and implementation support.
So, all given statements are correct.
Correct option is:
$\boxed{(a)\ \text{All the statements are correct}}$
