Cisco Graduate Apprenticeship Trainee Interview Questions and Answers

OOPs concept stands for Object-Oriented Programming concepts which includes encapsulation, inheritance, polymorphism, and abstraction.

• Encapsulation is the process of hiding the implementation details from the user.

• Inheritance allows a class to inherit properties and methods from another class.

• Polymorphism allows objects to take on multiple forms or behaviors.

• Abstraction is the process of hiding unnecessary details from

Lazy loading is a technique used to defer the loading of non-critical resources until they are needed.

• It improves page load time and performance.

• It is commonly used for images, videos, and other media files.

• It can be implemented using JavaScript libraries like LazyLoad or Intersection Observer API.

• Lazy loading can also be used for modules and components in web applications.

• It helps to reduce the initial load time of th

Eager loading is a technique used in software development to load related data in advance to avoid multiple database queries.

• Eager loading is used to optimize database queries and improve performance.

• It loads all the required data in a single query instead of making multiple queries.

• It is commonly used in Object-Relational Mapping (ORM) frameworks like Hibernate, Entity Framework, etc.

• Eager loading can be used with var...read more

Star delta starter is a type of motor starter used to reduce the starting current of an induction motor.

• It consists of three contactors and a timer.

• During starting, the motor is connected in star configuration to reduce the voltage across each winding.

• After a specified time, the motor is switched to delta configuration for normal operation.

• This reduces the starting current and torque, preventing excessive heating and m...read more

KCL and KVL are fundamental laws in electrical engineering.

• KCL (Kirchhoff's Current Law) states that the sum of currents entering a node is equal to the sum of currents leaving the node.

• KVL (Kirchhoff's Voltage Law) states that the sum of voltages around any closed loop in a circuit is equal to zero.

• KCL and KVL are used to analyze and solve electrical circuits.

• KCL and KVL are based on the principle of conservation of c
