Use Cases are used to define the interactions between a user and a system, detailing the steps the user takes to accomplish a specific goal.
- Flowcharts
- Use Cases
- User Stories
- Wireframes
Use Cases are a technique in software development to specify how a system interacts with its users. They outline a sequence of steps that a user or actor takes to achieve a specific task or goal within the system.
In traditional SDLC, the ______ phase can be lengthy and rigid, which is a limitation addressed by Agile methodologies.
- Design
- Development
- Requirements
- Testing
In traditional SDLC, the requirements phase can be lengthy and rigid, often involving extensive planning and documentation. Agile methodologies address this limitation by promoting more flexibility and iterative development, allowing for changes in requirements.
What considerations are crucial when setting up a CI/CD pipeline for microservices architecture?
- A single large code repository.
- Independent deployment and scaling.
- Monolithic application design.
- Tight coupling between microservices.
Setting up a CI/CD pipeline for microservices requires considering their independence, allowing for separate deployment and scaling. It enables flexibility and faster development in a microservices architecture.
During a software deployment, a company wants to test the new features on a small percentage of its servers before rolling it out to everyone. Which deployment strategy aligns with this approach?
- Blue-Green Deployment
- Canary Deployment
- Parallel Deployment
- Rolling Deployment
Canary Deployment aligns with testing new features on a small percentage of servers before wider release. It involves releasing updates to a subset of users, allowing early feedback and minimizing the impact of potential issues.
_____ is a practice that involves collecting, analyzing, and visualizing data about a software application's performance and behavior.
- Code Review
- Debugging
- Documentation
- Performance Analysis
Performance analysis is the practice of collecting and analyzing data to understand and optimize a software application's performance and behavior.
What challenges might a team face when conducting performance testing on a large-scale distributed system?
- High-performance hardware
- Limited data volume
- Network latency
- Small user base
Conducting performance testing on a large-scale distributed system can be challenging due to network latency issues, as data transmission delays can affect system performance.
Which programming paradigm emphasizes immutability and first-class functions?
- Functional Programming
- Logical Programming
- Object-Oriented Programming
- Procedural Programming
Functional programming is a paradigm that emphasizes immutability and first-class functions. Immutability ensures that data remains constant, and first-class functions allow functions to be treated as first-class citizens.
In Git, the _____ command is used to submit changes to the repository.
- add
- clone
- commit
- push
In Git, the "commit" command is used to submit changes to the repository. It records a snapshot of the changes you've made with a message describing what was done.
How does the use of a traceability matrix assist in managing and documenting requirements?
- It automates the testing process.
- It ensures that requirements are never changed.
- It generates code from requirements.
- It serves as a requirements repository.
A traceability matrix is a valuable tool that helps in managing and documenting requirements. It links requirements to their sources, making it easier to track changes, ensure completeness, and verify that all requirements have been addressed throughout the project.
What is the significance of properly documenting requirements in the SDLC?
- It ensures efficient communication
- It is optional
- It only helps developers understand
- It slows down the development process
Properly documenting requirements in the SDLC is crucial because it ensures efficient communication among all stakeholders. It serves as a common reference point, reduces misunderstandings, and helps in building software that meets user needs.
