You're working on a project where rapid prototyping is crucial. Which framework would be most suitable and why?

  • Express.js
  • Flask
  • Ruby on Rails
  • Spring Boot
Flask, a lightweight Python web framework, is ideal for rapid prototyping. Its simplicity and flexibility allow developers to quickly build and iterate on prototypes, making it a preferred choice for projects with tight timelines.

What is the difference between BFS (Breadth-First Search) and DFS (Depth-First Search)?

  • BFS always finds the shortest path, while DFS may not
  • BFS explores graph by depth, while DFS explores breadth-wise
  • BFS explores graph level by level, while DFS explores as far as possible along each branch before backtracking
  • BFS is recursive, while DFS is iterative
BFS (Breadth-First Search) explores a graph level by level, while DFS (Depth-First Search) explores as far as possible along each branch before backtracking. Understanding these differences is crucial for choosing the right algorithm for a specific problem.

Which AWS service is used for container orchestration?

  • AWS Lambda
  • Amazon ECS
  • Amazon RDS
  • Amazon S3
Amazon ECS (Elastic Container Service) is the AWS service used for container orchestration. It allows users to run, stop, and manage Docker containers on a cluster, making it easier to deploy and scale containerized applications.

What are the drawbacks of using serializability as the isolation level in database transactions?

  • Enhanced data integrity
  • Improved scalability
  • Increased data consistency
  • Reduced concurrency and performance
Serializability as the isolation level in database transactions comes with drawbacks, including reduced concurrency and performance. While it ensures strong data consistency, it may lead to contention for resources and slower processing times.

_______ is a principle in OOP that promotes the idea of coding to an interface rather than an implementation.
