What is the purpose of using Entity-Relationship diagrams in database design?
- To create program code.
- To manage hardware resources.
- To visualize data structures.
- To write user documentation.
Entity-Relationship diagrams (ER diagrams) are used in database design to visualize the data structure, including entities, attributes, and their relationships, helping in understanding the database's architecture.
In software development, a _____ is used to keep track of reported software bugs and their status.
- Bug Tracker
- Compiler
- Debugger
- Version Control
In software development, a "Bug Tracker" is used to keep track of reported software bugs and their status. It helps teams manage and prioritize bug fixes efficiently.
_____ can be used to visualize and specify how external actors interact with a system to achieve specific goals.
- Flowcharts
- Prototypes
- Use Cases
- User Stories
Use cases can be used to visualize and specify how external actors interact with a system to achieve specific goals, helping in requirements analysis and design.
You are part of a team responsible for the uptime and reliability of a critical e-commerce platform. How would monitoring and logging practices assist in ensuring the platform's availability and performance?
- They detect performance issues
- They ensure data privacy
- They have no impact
- They help identify new features
Monitoring and logging practices are crucial for detecting performance issues in a critical e-commerce platform. They provide insights into system behavior, errors, and bottlenecks, helping maintain uptime and reliability.
In Software Architecture Design, the _____ pattern involves dividing the system into interconnected components to improve modifiability and scalability.
- Component-Based
- Facade
- MVC
- Singleton
In Software Architecture Design, the "Component-Based" pattern involves dividing the system into interconnected components, enhancing modifiability and scalability.
What role does Software Architecture Design play in determining the overall system performance?
- It defines the system's performance attributes.
- It has no impact on performance.
- It only affects hardware performance.
- It solely depends on the development team.
Software Architecture Design plays a crucial role in determining the overall system performance by specifying performance attributes, like speed, scalability, and resource utilization, which guide development efforts for optimal performance.
A significant limitation of traditional SDLC models is the difficulty in accommodating _____ once the development has started.
- Documentation changes
- Requirements changes
- Risk management
- Stakeholder feedback
Traditional SDLC models face a significant limitation in accommodating Requirements changes once the development has started. These models follow a sequential approach, making it challenging to incorporate new requirements or changes without disrupting the entire process. Agile methodologies, in contrast, are more flexible and adaptable to changing requirements.
Why is it important for an organization to have an incident response plan?
- It addresses security breaches and threats
- It enhances employee morale
- It ensures constant monitoring
- It reduces productivity losses
An incident response plan is crucial for addressing security breaches and threats effectively. It helps minimize damage, safeguard sensitive data, and maintain the organization's reputation and trust. This plan outlines the steps to take when incidents occur.
You are reviewing a colleague's code and notice inconsistencies in naming conventions and indentation. How could adherence to a coding standard or style guide have prevented this?
- Coding standards are unnecessary
- Coding standards create bugs
- Coding standards improve code quality
- Coding standards slow down development
Adhering to a coding standard or style guide can prevent inconsistencies in naming and indentation. Coding standards provide a set of rules and best practices, ensuring code consistency and readability. This enhances code quality, makes maintenance and collaboration easier, and helps avoid common errors caused by inconsistent coding practices.
The _____ maintenance model involves making changes to a software product to correct issues discovered after its initial release.
- Adaptive
- Corrective
- Perfective
- Preventive
Corrective maintenance is the process of making changes to a software product to correct issues and defects discovered after its initial release. This type of maintenance aims to fix problems without adding new features or altering existing functionality.
What is the primary purpose of a bug tracking system in software development?
- Document software design
- Enhance software performance
- Facilitate communication among team members
- Track and manage software defects
A bug tracking system's primary purpose is to track and manage software defects, also known as bugs or issues. It helps in identifying, prioritizing, and resolving issues to improve software quality.
Why is the Software Development Life Cycle (SDLC) considered important for the development of high-quality software?
- It eliminates all bugs.
- It ensures low cost.
- It provides a systematic approach.
- It speeds up development.
SDLC is important because it offers a structured and systematic approach to software development. It helps in managing requirements, quality, and risk, leading to high-quality software.
