• Kubernetes architecture consists of master nodes, which manage the cluster, and worker nodes, where applications run.

• etcd is a distributed key-value store used for storing cluster data.

• kubelet is an agent that runs on each node and ensures containers are running.

• kube-proxy is a network proxy that maintains network ...read more

Agile is iterative and flexible, while waterfall is sequential and rigid.

• Agile focuses on delivering working software in short iterations, while waterfall follows a linear sequential approach.

• Agile allows for changes and adaptations throughout the project, while waterfall requires detailed planning upfront.

• Agile promotes collaboration and communication within the team, while waterfall relies on strict documentation and processes.

• Agile is better suited for projects with evolvi...read more

I would immediately communicate with my supervisor and team to discuss options and prioritize tasks to meet the deadline.

• Notify supervisor and team of potential delay

• Discuss options and prioritize tasks

• Work efficiently and effectively to meet the deadline

• Consider delegating tasks or seeking additional resources if necessary

No, static methods cannot be overridden in Java.

• Static methods belong to the class itself, not to instances of the class.

• Subclasses can define static methods with the same signature as the superclass, but it is not considered overriding.

• Example: Parent class has a static method 'display()', and child class also has a static method 'display()'. These are two separate methods, not overriding.

Outliers can be handled by removing or transforming them. Unbalanced datasets can be handled by resampling techniques.

• For outliers, use statistical methods like z-score or IQR to identify and remove them.

• For unbalanced datasets, use techniques like oversampling, undersampling, or SMOTE to balance the classes.

• For regression problems, use robust regression techniques like Ridge or Lasso to handle outliers.

• For classification problems, use algorithms like Random Forest or SVM tha...read more

JIT compiler stands for Just-In-Time compiler, which dynamically compiles and optimizes code during runtime.

• JIT compiler is used to improve the performance of applications by compiling code at runtime instead of ahead of time.

• It converts bytecode into native machine code on-the-fly, allowing for faster execution.

• Examples of JIT compilers include HotSpot for Java and V8 for JavaScript.

Spring supports five bean scopes: singleton, prototype, request, session, and application.

• Singleton scope creates a single instance per Spring IoC container.

• Prototype scope creates a new instance every time the bean is requested.

• Request scope creates a new instance for each HTTP request.

• Session scope creates a single instance per HTTP session.

• Application scope creates a single instance per ServletContext.

Singleton design pattern ensures a class has only one instance and provides a global point of access to it.

• Ensures a class has only one instance by providing a global access point to it

• Uses a private constructor to restrict instantiation of the class

• Provides a static method to access the single instance

Redux helps manage application state in a predictable way.

• Centralized state management

• Predictable state changes with actions and reducers

• Time-travel debugging with Redux DevTools

• Ecosystem of middleware for additional functionality
