SE UNIT -5 Advanced Software Maintenance Quiz

What is technical debt?

• The cost of legacy systems

• Future costs incurred by shortcuts in software development

• Financial debt of a software company

• Accumulated user feedback

Which of the following best describes "refactoring"?

• Adding new features to software

• Cleaning and restructuring code without changing functionality

• Replacing old code entirely

• Fixing bugs in a legacy system

What is a common challenge in managing legacy systems?

• High system reliability

• Lack of technical documentation

• Easy integration with new technologies

• Modern coding practices

What is the primary goal of code refactoring?

• Increase feature complexity

• Improve code readability and maintainability

• Ensure faster deployment

• Add backward compatibility

A phased approach to legacy system modernization is also called:

• Rip-and-replace

• Greenfield approach

• Incremental modernization

• Code-freezing

Which method integrates old systems with new technologies using a wrapper?

• Code replacement

• System refactoring

• Adapter or façade pattern

• API migration

What is a "Big Bang" approach to legacy system updates?

• Incremental deployment over time

• Complete system overhaul in one step

• Test-driven development

• Isolated sandbox testing

Reverse engineering of codebases helps in:

• Creating updated user manuals

• Analyzing existing architecture

• Speeding up coding time

• Building AI systems

A major risk of legacy system migration includes:

• Increased developer productivity

• Data loss or corruption during transition

• Reduction in technical debt

• Improved system reliability

What does "blue-green deployment" ensure during system updates?

• Simplified debugging

• Seamless and low-risk rollout

• Reduction in test cases

• Minimal cloud resource usage
