Associate Tech Specialist Interview Questions and Answers

Write-behind and write-through are caching schemes used to improve performance and data consistency.

• Write-behind cache scheme delays the write operation to the main storage until it is necessary, improving write performance.

• Write-through cache scheme writes data to both the cache and the main storage simultaneously, ensuring data consistency.

• Write-behind is suitable for scenarios where write performance is critical, but data consistency can be compromised temporarily.

• Write-th...read more

Java OOPs concepts include inheritance, polymorphism, encapsulation, and abstraction.

• Inheritance allows a subclass to inherit properties and methods from a superclass.

• Polymorphism allows objects to take on multiple forms and behave differently based on their context.

• Encapsulation hides the implementation details of an object and only exposes necessary information.

• Abstraction allows for the creation of abstract classes and interfaces that can be implemented by other classes.

Replicated cache stores copies of data on multiple nodes, while distributed cache partitions data across multiple nodes.

• Replicated cache provides high availability and fault tolerance as data is duplicated on multiple nodes.

• Distributed cache improves scalability and performance by distributing data across multiple nodes.

• In replicated cache, all nodes have a complete copy of the data, which can lead to higher memory requirements.

• In distributed cache, data is divided into parti...read more
