Software Development and Management Questions

Multiple choice technology security

An application is developed and deployed in production. A bug was found and a CR was raised and modified code is ready for deployment after following SSA and SDLC. This interim release of the application is called

  1. Release of CR

  2. maintenance of application

  3. release of patch

  4. interim release of CR
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A patch is a software update designed to fix a bug or vulnerability identified in production after the product is already released. Terms like 'release of patch' accurately represent this interim update, whereas 'maintenance' is a broad phase rather than the release package itself.

Multiple choice technology security

You are asked to develop an application from scratch. When will you start performing Threat Modeling of the application

  1. At the design stage

  2. At the beginning of testing phase

  3. During requirements collection phase

  4. HP Webinspect performs the Threat Modeling, I do not need to do anything
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Threat modeling should begin during the requirements collection phase when the application's purpose, data flows, and user interactions are being defined. Identifying potential threats early allows architects to design security controls into the system rather than retrofitting them later, which is more effective and economical.

Multiple choice technology security

Which of the following is a valid threat modelling methodology

  1. STRIDE

  2. PRIDE

  3. BRIDE

  4. RIDE
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

STRIDE is a widely recognized threat modeling methodology developed by Microsoft. It helps identify security threats across six categories: Spoofing, Tampering, Repudiation, Information disclosure, Denial of service, and Elevation of privilege. PRIDE, BRIDE, and RIDE are distractors.

Multiple choice

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:

  1. I-II-III-IV-V

  2. V-IV-III-II-I

  3. I-III-V -II-IV

  4. IV-II-V -III-I
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Software coupling types ranked from strongest (worst) to weakest (best): Content coupling (I) - modules share internal data; Common coupling (II) - share global data; Control coupling (III) - one module controls another's logic; Stamp coupling (IV) - share structured data; Data coupling (V) - only pass simple data. The order I-II-III-IV-V is correct.

Multiple choice

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

  1. Functional Requirements

  2. Non Functional Requirements

  3. Goals of Implementation

  4. Algorithms for Software Implementation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

An SRS document specifies WHAT the software should do (functional requirements, non-functional requirements, and implementation goals), not HOW to implement it. Algorithms and implementation details belong in design documents, not requirements specifications. Mixing implementation details with requirements reduces flexibility and constrains design choices unnecessarily.

Multiple choice

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?

  1. 234.25

  2. 932.50

  3. 287.80

  4. 122.40
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Effort person per month = $\alpha.$(kDSI)B KDSI = kilo LOC = 2.8×(40)1.20 = 2.8×83.6511 = 234.22 person per month

Multiple choice

A company needs to develop a strategy for software product development for which it has a choice of two programming languages L1 and L2. The number of lines of code (LOC) developed using L2 is estimated to be twice the LOC developed with L1. The product will have to be maintained for five years. Various parameters for the company are given in the table below.

Parameter Language L1 Language L2
Man years needed for development LOC/10000 LOC/10000
Development Cost per year Rs. 10,00,000 Rs. 7,50,000
Maintenance time 5 years 5 years
Cost of maintenance per year Rs. 1,00,000 Rs. 50,000

Total cost of the project includes cost of development and maintenance. What is the LOC for L1 for which the cost of the project using L1 is equal to the cost of the project using L2?

  1. 4000

  2. 5000

  3. 4333

  4. 4667
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

LOC L1 = x 2 L = 2x Total cost of project $\dfrac{x}{10000}\times1000000 + 5 \times 100000 = \dfrac{2x}{10000}\times750000+50000\times5$ 100x + 500000 = 150x + 250000 $\Rightarrow$50x = 500000 – 250000 $\therefore$        $x = \dfrac{250000}{50} \Rightarrow x = 5000$
