In Jenkins, what is the primary role of a Docker agent?
- Distributing build tasks to multiple agents
- Managing Jenkins configurations
- Monitoring system performance
- Running builds in isolation using Docker containers
The primary role of a Docker agent in Jenkins is to run builds in isolation using Docker containers. This allows for consistent and reproducible builds in isolated environments.
How does the Canary deployment strategy help in minimizing the impact of errors in a software release?
- It deploys changes to a small subset of users.
- It detects errors after the release.
- It eliminates the possibility of errors.
- It rolls back the entire release in case of an error.
The Canary deployment strategy involves releasing changes to a small group of users first. This allows early detection of errors, minimizing the impact and enabling adjustments before a full release.
What considerations should be taken into account when prioritizing patches for deployment?
- Employee preferences
- Patch severity and business impact
- Patch size and download speed
- Vendor's popularity
Prioritizing patches should consider patch severity and its potential impact on the organization's operations. Factors like patch size and download speed are less important than the impact on business operations and data security.
How does monitoring and logging contribute to the incident response and recovery process?
- They cause incidents.
- They do not play a role in incident response.
- They help in identifying and diagnosing incidents.
- They immediately fix incidents.
Monitoring and logging provide real-time data and historical records, helping incident response teams identify, diagnose, and respond to incidents effectively. They are essential for incident management and recovery.
After several meetings with stakeholders, a project manager has gathered a large amount of data regarding a new software system. What should be the next step in terms of documenting these requirements?
- Create a formal requirements document
- Develop a comprehensive test plan
- Prioritize the requirements and create a traceability matrix
- Validate the gathered requirements with stakeholders
The next step should be to validate the gathered requirements with stakeholders. This ensures that the requirements accurately reflect their needs and expectations, reducing the risk of misunderstandings and changes later in the project.
A company wants to develop a software product with minimal risks and a focus on regular improvement and refinement. Which SDLC model would be most suited to this approach?
- Big Bang Model
- Iterative Model
- Scrum Model
- Spiral Model
Scrum is suitable for projects with a focus on regular improvement and refinement. It promotes iterative development and continuous feedback, reducing risks and enabling constant product enhancement.
The _____ principle of User Interface Design states that the design should minimize the user's memory load.
- Affordance
- Consistency
- Feedback
- Visibility
The "Consistency" principle of User Interface Design emphasizes that design should be consistent to minimize the user's memory load, ensuring predictability.
In a CI/CD pipeline, the _______ stage is responsible for ensuring that the code changes do not break the existing functionality.
- Deployment
- Integration
- Testing
- Validation
In a CI/CD pipeline, the "Validation" stage ensures that code changes do not break existing functionality by running tests and checks before deployment.
The _____ approach in prototyping involves building small and incremental portions of a system and expanding upon it based on feedback.
- Agile
- Big Bang
- Incremental
- Spiral
The _____ approach in prototyping involves building small and incremental portions of a system and expanding upon it based on feedback. It is known as the "Incremental" approach and is common in Agile methodologies.
In software maintenance, _____ refers to the practice of regularly checking and updating software to ensure its optimal performance.
- Adaptive
- Corrective
- Perfective
- Preventive
Preventive maintenance involves regular checks and updates to ensure software's optimal performance, preventing issues before they occur.
