A software organization planned to develop a mobile application that can be used by any other organization for its employees to manage their leaves and holidays efficiently. The software organization interviewed employees from different organizations to collect requirements. In this case, which type of client is the software organization dealing with?

A software company has implemented a website for a school. The website is given to the school faculty members to verify if the website meets the requirements provided by the school. The faculty members use the website and find that when they try to upload results of more than 1000 students, the website crashes. Which phase of the SDLC is the software currently in?

Consider the following two requirements for a school portal: Requirement 1: The portal should allow bulk upload of the students' marks. Requirement 2: The portal should allow a student to download his or her marksheet within 30 seconds. Which of the following statements is **true**?

Which of the following UML diagrams models flow of control among computational activities?

Which of the following software can be used for sharing and maintaining code versions?

A prototype is presented as a web application along with some fabricated data. Determine the prototype type that has been provided.

Suppose the risk assessed for personnel shortfall in a given software project is 1.8. The probability that personnel shortage will occur during project development is 0.6. What is the impact of personnel shortage on the given project?

Consider a module Deque that maintains a doubly linked list. The module Deque has the following functions: - push_back(e) : adds an element e at the back of the doubly linked list, - push_front(e) : adds an element e at the front of the doubly linked list, - pop_back(): removes an element from back of the doubly linked list, - pop_front(): removes an element from front of the doubly linked list. Identify the type of cohesion for the module Deque.

Match the following regarding the outcomes of software design process.

Consider an eCommerce portal that has integrated a set of APIs to recommend products to customers based on their carts. Which of the following debugging strategies involves the task of searching the documentation and code examples to understand the correct use of the APIs?

Consider the Python code below.

What is the cyclomatic complexity of this code?

Consider designing an online gift store that delivers various gift items in a variety of ways, such as direct pick-up from the store, delivery by its own logistics team, or delivery by other delivery partners. To support the delivery process, an interface DeliveryProcessing is being designed, which is further implemented by the classes that provide the implementation for specific delivery processes. The interface DeliveryProcessing specifies the methods to be implemented by any delivery class, and those are packageOrder(), notifyCustomer(), bookDeliveryPartner() and deliver(). The online gift store also has digital gift items like gift coupons, software games, etc., and for delivering these items, most of the methods in the interface DeliveryProcessing are not relevant. However, since the interface DeliveryProcessing needs to be implemented by any delivery class, delivery classes for digital gift items also need to implement the methods from DeliveryProcessing which are not at all relevant to those items. Identify the SOLID principle that is missing from the design process.

An organization provides its employees with a mobile app that allows them to apply for leave. To select dates, it pops out a calendar; however, the calendar cannot highlight the holidays separately. As a result, there is a huge chance that an employee will apply for leaves on holidays. Which of the following heuristics of UI evaluation is missing in the mobile app?

Suppose a job portal has a class Applicant for representing the candidates applying for jobs. Class Applicant has a few mandatory fields (like name, contact number, email) and a large number of optional fields (like experience, passport number, PAN number), which necessitates the designer to write a large number of constructors to instantiate the object of Applicant class (one constructor with only initializing all the mandatory fields and a number of constructors for different numbers and different combinations of optional fields along with all mandatory fields). Which of the following design patterns can be best suited for solving the problem of creating a large number of constructors?

A software company has to develop an automated gardening system to control soil moisture and other chemical components in soil. The developed software should be strongly coupled with the hardware, like sensors, controllers, motors, etc.  The values for the constants in the COCOMO model for the various types of projects are as follows: - Organic project: a = 2.4, b = 1.05 - Semi-detached project: a = 3.0, b = 1.12 - Embedded project: a = 3.6, b = 1.20 Given the source code of 1,00,000 lines and the developer's monthly salary of Rs. 50,000/-, what is the initial estimated cost for the project?

Which of the following is/are the main advantage(s) of prototype model for software development?

Consider the activity network diagram for developing a food delivery mobile app as given below.

Select the correct observations for the given activity network.

Consider a software organization developing an online gift shop where customers can place an order to send gifts to their friends and family members staying in the same city. The customers can select from a range of gifts and place an order. After placing the order, the store manager contacts the courier service provider via phone call to collect the item from the physical store and schedule delivery. Based on the above data, answer the given subquestions.

Identify the most appropriate user type for the courier service provider.

The customers can select from a range of gifts and place an order. After placing the order, the store manager contacts the courier service provider via phone call to collect the item from the physical store and schedule delivery. Based on the above data, answer the given subquestions.

The developers of the online gift store want to explore the types of gift items to be kept in the catalog. Therefore, they want to gather responses for some specific questions from a large group of people. Which requirement gathering technique would be the most effective for this purpose?

The customers can select from a range of gifts and place an order. After placing the order, the store manager contacts the courier service provider via phone call to collect the item from the physical store and schedule delivery. Based on the above data, answer the given subquestions.

Consider a user story for the online gift shop that describes the following feature: Feature 1: Search catalog and place order However, it has been found that implementation of Feature 1 is not possible within one agile iteration. Therefore the Feature 1 is subdivided as follows: Feature 1a: Search catalog and Feature 1b: Place order Which of the SMART characteristics is fulfilled by the refinement?

A software company has plans to develop a web application and a mobile application that can assess equities and recommend their purchase or sale. Nevertheless, the product might not be competitive in the market due to the abundance of similar products that are already available.  This is a potential risk associated with its development. Based on the above data, answer the given subquestions.

Identify the type of the risk in the given scenario.
