Which of the following is a common method to enhance cybersecurity in web applications? A) SQL Injection B) Cross-Site Scripting (XSS) C) Input Validation D) Denial of Service (DoS) attacks II. Practical Coding (Programming Exercises) 1. Write a Python function that takes a list of integers as input and returns the sum of all even numbers in the list. 2. Given a database table named employees with columns id, name, and salary, write an SQL query to retrieve the names of employees whose salary is above $50,000. III. System Design (Essay) 1. Explain the difference between microservices and monolithic architecture. Provide a scenario where each would be preferable. 2. Discuss the advantages and challenges of migrating a traditional on-premise system to a cloud-based infrastructure. 3. Define scalability in the context of software systems. Provide strategies for designing a scalable application.  Answer Key I. Core Concepts (Multiple Choice) 1. B 2. A 3. A 4. A 5. C II. Practical Coding (Programming Exercises) 1. def sum_of_evens(lst): return sum(x for x in lst if x % 2 == 0) 2. SELECT name FROM employees WHERE salary > 50000; III. System Design (Essay) 1. Microservices involve breaking down an application into small, independent services. Monolithic architecture has all components in a single codebase. Microservices are preferable for scalability and flexibility, while monolithic is simpler for small projects. 2. Advantages include scalability and cost-effectiveness. Challenges involve security and potential data transfer costs. 3. Scalability refers to a system's ability to handle increased load. Strategies include load balancing, horizontal scaling, and caching. CHOOSE & DOWNLOAD MORE EXAM TEMPLATE © TEMPLATE.NET
