What is the primary purpose of using a Source Code Management (SCM) tool in software development?
- To design user interfaces
- To test software
- To track and manage changes
- To write code
The primary purpose of using an SCM tool is to track and manage changes to the source code. It helps developers collaborate, maintain version history, and ensure code integrity.
Which SDLC model is characterized by a linear sequence of phases in which progress flows in one direction—like a waterfall—through the phases of Conception, Initiation, Analysis, Design, Construction, Testing, Deployment, and Maintenance?
- Agile Model
- Spiral Model
- V-Model
- Waterfall Model
The Waterfall Model is characterized by a linear sequence of phases, where each phase depends on the deliverables of the previous one. It's a rigid but systematic approach to software development.
In the _____ prototyping model, a developer creates a model that quickly represents only those aspects of the software that are of interest.
- Agile
- Evolutionary
- Incremental
- Throwaway
In the "Throwaway" prototyping model, a developer creates a model that quickly represents only those aspects of the software that are of interest, with the intention of discarding it after gathering feedback and requirements.
Which phase in the SDLC primarily focuses on defining and prioritizing the requirements for the product?
- Design Phase
- Maintenance Phase
- Requirements Phase
- Testing Phase
The Requirements Phase in the SDLC is where the primary focus is on gathering, defining, and prioritizing the project's requirements, ensuring alignment with the desired product.
A company notices that their application slows down during peak usage times. Which monitoring and logging metrics would be most beneficial to diagnose the issue?
- Employee satisfaction
- Marketing campaign success
- Memory usage, CPU utilization
- Number of bug fixes
Monitoring and logging metrics like memory usage and CPU utilization are crucial to diagnose performance issues during peak usage. These metrics help identify resource bottlenecks causing slowdowns.
What considerations are typically evaluated during the Feasibility Study in the initial phases of the SDLC?
- Hardware requirements
- Market analysis
- Software testing
- Technical feasibility
During the Feasibility Study in the initial phases of SDLC, technical feasibility assesses whether the proposed project is technically possible, considering hardware, software, and other technical requirements. This evaluation helps decide whether to proceed with the project. Other aspects like market analysis, hardware, and software testing are considered later in the SDLC.
The process of identifying bottlenecks, or slow-performing areas in a software application, is known as _____ testing.
- Black-box
- Performance
- Usability
- White-box
Performance testing is the process of identifying bottlenecks or slow-performing areas in a software application, ensuring it meets performance requirements.
You are part of a team developing a new social media application. In which phase of the SDLC would your team ensure that the application can handle a large number of simultaneous users without performance degradation?
- Design Phase
- Maintenance Phase
- Requirements Phase
- Testing Phase
The team would ensure performance in the Testing Phase. This phase includes load testing, stress testing, and performance testing to verify that the application can handle a large number of users without degrading performance.
What role does a patch management system play in ensuring software security?
- It applies security updates and fixes
- It detects all security flaws
- It encrypts all data
- It prevents all security breaches
A patch management system is crucial for software security as it identifies and applies security updates and fixes, thereby addressing vulnerabilities that could be exploited by attackers.
How does automated testing improve the efficiency of the software development process compared to manual testing?
- Automated testing is faster and repeatable.
- Automated testing is less reliable.
- Automated testing requires manual documentation.
- Automated testing requires more human effort.
Automated testing is more efficient as it can quickly and consistently run tests, identify issues, and provide rapid feedback to developers, saving time compared to manual testing.
