The _______ phase of the SDLC involves validating the requirements to ensure they align with the project's objectives.
- Design
- Planning
- Requirements
- Testing
The Requirements phase of the SDLC involves validating the requirements to ensure they align with the project's objectives. This phase is crucial for establishing a clear project scope and ensuring that the requirements are realistic and achievable.
During _____ testing, a software application is tested with a specific expected load to evaluate its performance.
- Acceptance
- Alpha
- Beta
- Stress
During "Stress" testing, a software application is tested under a specific expected load to assess its performance under extreme conditions and to identify its breaking point.
How does the V-Model in SDLC ensure that the processes in the development and testing phases correspond with each other?
- By conducting testing before the development phase to identify issues earlier
- By defining corresponding development and testing phases in a sequential and parallel manner
- By outsourcing the testing phase to a different team
- By overlapping development and testing phases for quicker results
The V-Model ensures that development and testing processes correspond by defining corresponding development and testing phases that run in a sequential and parallel manner. It emphasizes testing requirements based on corresponding development phases, improving alignment and effectiveness.
The _______ model of SDLC combines the features of both the waterfall model and the prototype model.
- Agile
- Spiral
- V-Model
- Waterfall-Prototype
The Waterfall-Prototype model combines characteristics of the traditional Waterfall model and the iterative Prototype model. It allows for early feedback like prototyping while maintaining a structured approach like Waterfall.
The _____ SOLID principle states that classes should be open for extension but closed for modification.
- Dependency
- Liskov
- Open-Closed
- Single
The Open-Closed SOLID principle states that classes should be open for extension but closed for modification. It promotes software design that allows for new functionality to be added without altering existing code.
By creating _____ in a database, you can speed up the retrieval of rows from a database table.
- Aggregates
- Indexes
- Procedures
- Views
By creating "Indexes" in a database, you can speed up the retrieval of rows from a database table. Indexes provide a faster way to locate specific data, enhancing database query performance.
To simulate network latency and test how an application performs under stress, _____ testing is conducted.
- Load
- Penetration
- Performance
- Stress
Load testing is a type of testing that simulates network latency and tests how an application performs under stress by subjecting it to various loads. It helps determine the application's response time, scalability, and reliability under different levels of user activity, ensuring it can handle the expected workload.
What are the key components of an effective incident response strategy?
- Assigning blame and reprimanding staff
- Communication and collaboration
- Delaying any action
- Ignoring the incident
An effective incident response strategy includes communication and collaboration, not assigning blame. It's important to respond promptly, work together, and learn from the incident to improve future responses. Ignoring or delaying an incident is not a recommended approach.
How does Test-Driven Development (TDD) contribute to cleaner code and better software design?
- It avoids code reviews.
- It emphasizes refactoring.
- It encourages minimal testing.
- It focuses on testing after coding.
Test-Driven Development (TDD) contributes to cleaner code and better software design by emphasizing refactoring. Refactoring ensures that code remains clean, maintainable, and optimized as it evolves, improving software quality.
In the context of monitoring, _____ refers to automatically adjusting resources based on the application's demand.
- Auto-scaling
- Load balancing
- Performance optimization
- Resource allocation
Auto-scaling is a monitoring and management practice that automatically adjusts resources (such as server capacity) based on an application's demand. It ensures that the application can handle varying workloads efficiently.
