Why additional principles improve quality in LLD - Quick Recap

Recall & Review

beginner

What is the main benefit of applying additional design principles in system design?

Applying additional design principles helps create systems that are easier to maintain, scale, and understand, leading to higher quality and fewer errors.

intermediate

How do additional principles help reduce technical debt?

They encourage writing clean, modular, and well-structured code, which makes future changes easier and reduces the chance of accumulating messy, hard-to-fix problems.

intermediate

Why does following multiple principles improve system scalability?

Multiple principles guide the design to separate concerns and optimize components independently, allowing the system to handle growth smoothly without major rewrites.

beginner

Explain how additional principles improve collaboration among developers.

They provide a common language and structure, making it easier for team members to understand each other's work and reduce misunderstandings.

intermediate

What role do additional principles play in improving system reliability?

They promote practices like error handling, testing, and clear interfaces, which help prevent failures and make the system more dependable.

Why do additional design principles improve system quality?

A They remove all bugs automatically

B They make the system easier to maintain and scale

C They slow down development

D They add more code to the system

Additional principles guide better structure and clarity, making maintenance and scaling easier.

Which of the following is a benefit of applying multiple principles in design?

A Improved collaboration among developers

B Increased technical debt

C More complex and confusing code

D Slower system performance

Principles create a shared understanding, improving teamwork.

How do additional principles help with system scalability?

A By tightly coupling components

B By removing modularity

C By ignoring future growth

D By separating concerns and optimizing parts independently

Separating concerns allows parts to scale without affecting others.

What is a common effect of following more design principles?

A Easier to understand and maintain code

B More bugs in the system

C Longer and more complicated code

D Less reliable systems

Principles encourage clarity and structure, reducing bugs and confusion.

Which practice is encouraged by additional principles to improve reliability?

A Ignoring error handling

B Skipping documentation

C Writing clear interfaces and testing

D Avoiding modular design

Clear interfaces and testing help catch and prevent failures.
