What are access specifiers in OOP languages such as Java and C++?
- They are used for exception handling
- They control the visibility of a variable
- They define the access rights for classes, methods, and attributes
- They specify the size of data types
Access specifiers in OOP languages like Java and C++ determine the visibility and access rights of classes, methods, and attributes. The three main access specifiers are public, private, and protected. Public members are accessible from any part of the program, private members are only accessible within the same class, and protected members are accessible within the same class and its subclasses. These specifiers play a crucial role in encapsulation and defining the scope of class members.
_______ is a technique used to optimize database performance by storing frequently accessed data in memory.
- Caching
- Clustering
- Indexing
- Partitioning
Caching is a technique used to optimize database performance by storing frequently accessed data in memory, reducing the need to fetch it from the disk.
How does the concept of abstraction apply in Object-Oriented Programming?
- Abstraction allows hiding implementation details while showing the essential features of a system.
- Abstraction is not applicable in Object-Oriented Programming.
- Abstraction prevents code from being reused.
- Abstraction simplifies code by removing unnecessary details.
Abstraction in Object-Oriented Programming refers to the concept of simplifying complex systems by hiding unnecessary details while showing only the essential features of objects. It allows for managing complexity by focusing on what an object does rather than how it does it.
Implementing _______ encryption helps protect sensitive data in transit.
- Advanced Encryption Standard (AES)
- Data Encryption Standard (DES)
- Public Key Infrastructure (PKI)
- Transport Layer Security (TLS)
Implementing Transport Layer Security (TLS) encryption helps protect sensitive data in transit. TLS is a cryptographic protocol that ensures secure communication over a computer network, commonly used for securing web traffic.

Infrastructure as Code helps in minimizing human errors. By automating the provisioning and management of infrastructure, IaC reduces the risk of manual mistakes in configuration.
How does the Prototype design pattern differ from the Builder design pattern?
- Both patterns serve the same purpose and can be used interchangeably
- Builder focuses on constructing a complex object step by step, abstracting the construction process
- Prototype focuses on creating new objects by copying an existing object, emphasizing cloning
- Prototype is used for creating complex objects with varying representations
The Builder design pattern focuses on constructing a complex object, allowing for step-by-step construction, while the Prototype pattern emphasizes creating new objects by copying an existing one, focusing on cloning.
