The Strategy design pattern defines a family of _______ algorithms and encapsulates each one, making them interchangeable.
- dependent
- interchangeable
- nested
- related
The Strategy design pattern defines a family of interchangeable algorithms. It allows a client to choose from a family of algorithms and gives them the flexibility to interchange algorithms without altering the client code.
What is the primary purpose of responsive web design?
- To ensure a consistent user experience across various devices and screen sizes

Explain the difference between query optimization in relational databases and NoSQL databases.
- NoSQL databases do not require query optimization since they are schema-less.
- Optimization in relational databases focuses on SQL queries and involves techniques like indexing and join strategies. NoSQL optimization varies based on the specific database type (e.g., document, key-value, graph), often emphasizing distributed and horizontal scaling.
- Optimization strategies are similar, emphasizing efficient indexing and join operations in both relational and NoSQL databases.
- Query optimization is irrelevant in NoSQL databases as they are designed to handle unstructured data without optimization.
Query optimization in relational databases involves SQL-specific techniques, while NoSQL optimization is context-dependent on the type of NoSQL database used.
You're working on a project that requires real-time data processing. Which cloud platform service would you recommend, and why?
- AWS Lambda
- Azure Stream Analytics

_______ is the process of creating a new class from an existing class in OOP.
- Abstraction
- Encapsulation
- Inheritance
- Polymorphism
Inheritance is the process of creating a new class from an existing class in OOP. It allows a new class (subclass or derived class) to inherit the properties and behavior of an existing class (superclass or base class).
GitHub Flow emphasizes continuous _______ as a best practice.
- delivery
- deployment
- integration
- testing
GitHub Flow emphasizes continuous delivery as a best practice. This means that changes should be deployable at any time, ensuring a smooth and reliable delivery process.
CAP theorem states that in distributed data stores, it's impossible to simultaneously provide more than two out of three guarantees: _______ consistency, _______ availability, and _______ tolerance.
- Consistent, Available, Partition
- Consistent, Reliable, Partition
- Causal, Available, Persistent
- Consistent, Available, Tolerant
CAP theorem asserts that in a distributed system, it's impossible to achieve all three of Consistency, Availability, and Partition Tolerance simultaneously. The correct options are Consistent, Available, and Partition Tolerance.
