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.
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.
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.
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.
One common coding best practice is to write _____ code, meaning the code's functionality is easy to determine and understand.
- Clear
- Complex
- Cryptic
- Obfuscated
One common coding best practice is to write clear code. Clear code is easy to understand, maintain, and modify, enhancing the software's quality.
The _____ model in SDLC is often referred to as the "verify and validate" model as it emphasizes the importance of parallel testing.
- Incremental
- Prototype
- RAD
- V-Model
The V-Model in SDLC is often referred to as the "verify and validate" model due to its emphasis on parallel testing and validation at each stage.
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.
A company is designing a database to store large volumes of transactional data with a focus on read performance. Which database design technique might they consider to optimize data retrieval times?
- Denormalization
- Indexing
- Normalization
- Partitioning
To optimize read performance for large volumes of data, denormalization is a technique. It involves reducing the level of normalization to decrease the number of joins and improve query performance.
A _____ tool in Configuration Management helps in automating the deployment and configuration of servers.
- Containerization
- Orchestration
- Scripting
- Virtualization
In Configuration Management, an Orchestration tool automates the deployment and configuration of servers. It streamlines tasks, ensures consistency, and enhances efficiency in managing a large number of servers.
A software development team is considering integrating Test-Driven Development (TDD) into their workflow. What considerations should they take into account regarding the impact on development time and code quality?
- TDD has no impact on development time or code quality.
- TDD is only suitable for specific project types.
- TDD may lead to longer development times and lower code quality.
- TDD typically shortens development times and improves code quality.
When considering TDD, a team should recognize that, while it may require an initial adjustment period, it typically results in shorter development times and higher code quality due to continuous testing. It's a valuable practice for many types of projects.
What considerations should be taken into account while gathering requirements to ensure they are complete and clear?
- Ambiguous Language
- Changing Requirements
- Inadequate Stakeholder Involvement
- Lack of Testing
When gathering requirements, it's important to consider avoiding ambiguous language to ensure completeness and clarity. Ambiguities can lead to misunderstandings and incomplete requirements, which can impact the quality of the software being developed.
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.
