Explanation: The first phase of the software development life cycle is the requirement analysis, in which the software engineer analyzes the software requirement based on the user's outlook.

Explanation: RAD stands for Rapid Application Development is categorized as an agile development method, which is meant to accomplish a quick turnaround and high-end outcomes. Explanation: There is nothing as such called Diagonal Prototype; however, the rest other options do make sense.

Explanation: The client may create an unrealistic product vision, which may result in a team over or under-develop functionality. Explanation: The evolutionary process model is designed for rapid software development, which starts from scratch with raw specifications and modifies as per the user requirement. Explanation: A spiral model is an incremental approach, which is formed as a combination of the waterfall model and prototyping model. The major drawbacks of the Spiral model are as follows:.

Explanation: Model selection is based on requirements, a team of developers, users as well as the risk involved in developing a project. Explanation: In the Prototyping model, the first phase is the requirement analysis phase, which involves Brainstorming, QFD, and FAST, whereas the Spiral model encompasses customer communication activities such as defining objectives. Explanation: The Prototyping model necessitates user participation as when a prototype is created or designed, whereas, in the case of RAD, user participation is required in all four phases.

Explanation: Functional processing or testing is commonly known as black-box testing, where the existing contents are almost unknown, so anything could be demonstrated as a black box.

Hence the functionality of a black box can be defined in terms of inputs and outputs. Explanation: Fourth-generation language is an advancement of third-generation programming language.

Explanation: The fourth-generation programming languages are more programmer-friendly and helpful in augmenting the program's efficiency as it uses English words and phrases. It increases the programmer's productivity by enabling them to engage in the software development life cycle. Explanation: Much more expertise is needed in the 4GT model for analyzing, designing, and testing activities as it eliminates the coding phase.

Explanation: For systems with long life, software maintenance cost is higher than that of the software development cost. Explanation: The deployment phase is the last phase of the software development life cycle in which the software product is delivered to its end-user, who further assesses its performance and revert back with the feedback if anything is required or missing as per the formulated evaluation.

What is the purpose of static perspective? Explanation: Software verification is mainly considered for implementing and testing activities. Explanation: In agile software development, the software is usually developed in increments with the customer specifying necessary requirements in each increment.

Here the main aim of a developer is to meet customer satisfaction at the earliest by providing a valuable software product.

It is known as iterative because it chooses to work on one particular increment and make the improvement in other iteration. Explanation: In software engineering, a plan-driven approach is based on several development stages that result in the output at each of these stages, which are already planned in advance. Explanation: Testing can never be avoided as it plays a significant role in the software development life cycle. Explanation: An Adaptive Software Development approach is an empirical process control model, which is based on observations.

It continuously adjusts the design of the solution and the process involved to create the solution based on observation throughout the project. Explanation: To represent the system's dynamic behavior, Behavioral models are used. The behavioral model is modeled from the perspective of the system's processed data or the events that stimulate responses from a system.

Explanation: Model-driven engineering is a software development approach that represents the system as a set model, which can be easily altered into an executable code.

Explanation: The cumulative cost is represented by the radial dimension, whereas the angular dimension represents the progress made in the completion of each consecutive cycle. Each loop in the spiral model depicts the phase.

Explanation: The process involved in certifying the sustained development of legacy systems relies on Reverse engineering and Reengineering. Explanation: An algorithm is a precise step-by-step technique that takes an input instance of the given problem as input s and produces output for the problem instance.

Explanation: The quality of a functional software functional depicts how well it can conform with or adapts to a given design based on functional requirements or specifications.

Answer: c All the functions represented in the DFD are mapped to a module structure. Explanation: In the business information system, the data flow diagram is used to epitomize the flow of the data. Explanation: A logical file can be a data structure or physical file on the disk or vice versa.

Explanation: Efficiency can never be measured as it is an indirect measure of the SE process. Answer: d To minimize the development schedule and evaluate the ongoing project's quality on a daily basis.

Explanation: A project metric refers to a quantifiable measure of the degree to which a system, component, or process owns a certain trait. Explanation: A control chart is a method used to keep track of the variability of traits of interest. Explanation: Estimation cost works out on assessing the amount of effort required to complete each activity, followed by calculating the total cost of activities.

Explanation: Configuration management policies and processes define how to record, and process proposed system changes, how to decide what system components to change, how to manage different versions of the system and its components, and how to distribute changes to customers.

Answer: a The ability to translate the size estimate into human effort, calendar time, and dollars. Explanation: In computer software, the estimation model uses empirically derived formulas for guessing the effort as a function of LOC or FP. Explanation: The algorithmic cost modeling utilizes the basic regression formula with such parameters that have been derived from the data of a historical project and current as well as characteristics of a future project.

Explanation: An application-composition model evaluates the development of a prototype. Explanation: Technical risks detect the possible design, enactment, interface, authentication, and preservation problems. Explanation: Once the risks are identified, the project manager takes his first step to avoid them when required and control them.

Software Engineering. Coding Programming Style Structured Programming. Answer: d Preliminary Investigation and Analysis Explanation: The first phase of the software development life cycle is the requirement analysis, in which the software engineer analyzes the software requirement based on the user's outlook.

Answer: c System Analysis Explanation: The study of an existing system refers to system analysis. Answer: d All of the above Explanation: None.

Answer: b Rapid Application Development Explanation: RAD stands for Rapid Application Development is categorized as an agile development method, which is meant to accomplish a quick turnaround and high-end outcomes. Answer: d Diagonal Prototype Explanation: There is nothing as such called Diagonal Prototype; however, the rest other options do make sense. Answer: d All of the above Explanation: The evolutionary process model is designed for rapid software development, which starts from scratch with raw specifications and modifies as per the user requirement.

Answer: b Doesn't work well for smaller projects Explanation: A spiral model is an incremental approach, which is formed as a combination of the waterfall model and prototyping model. The major drawbacks of the Spiral model are as follows: Expensive Doesn't work well for smaller projects Risk analysis requires highly skilled experts. Answer: d All of the above Explanation: Model selection is based on requirements, a team of developers, users as well as the risk involved in developing a project.
