A company wants to deploy a critical update to its software without causing any downtime. Which deployment strategy would be most suitable?
- Blue-Green Deployment
- Canary Deployment
- Parallel Deployment
- Rolling Deployment
Blue-Green Deployment is suitable for deploying critical updates without downtime. It involves creating an identical environment and switching traffic once the update is validated, ensuring minimal disruption to users.
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.
The _____ phase of incident response involves taking actions to minimize the impact of an incident and prevent further damage.
- Detection
- Mitigation
- Prevention
- Recovery
The mitigation phase in incident response involves taking actions to minimize the impact of an incident and prevent further damage, often by isolating affected systems and applying security measures.
Which scenario is more suitable for manual testing over automated testing?
- Ensuring complete code coverage.
- Load testing to simulate heavy user loads.
- Regression testing on a frequently changing codebase.
- Testing repetitive, time-consuming tasks.
Manual testing is more suitable for scenarios like load testing, which require a human perspective and judgment to simulate real-world usage conditions, something automation may struggle with.
Which coding best practice emphasizes making code understandable for both the computer and human readers?
- Code encryption
- Code obfuscation
- Code optimization
- Code readability
Code readability is a coding best practice that emphasizes making code understandable for both the computer and human readers. Clear and readable code is easier to maintain and debug.
Which of the following best describes the term "software update"?
- Adding new hardware
- Modifying software code
- Updating software to a newer version
- Upgrading the operating system
A "software update" refers to the process of updating software to a newer version. These updates typically include bug fixes, new features, and security improvements, ensuring the software's optimal performance.
