Dockerizing .NET Core Applications

What is Docker primarily used for?

• Virtualizing operating systems

• Creating, deploying, and scaling applications using containers

• Replacing traditional databases

• Running only .NET Core applications

What is a Docker image?

• A running instance of a container

• A lightweight, standalone package that includes application code and dependencies

• A virtual machine instance

• A type of database used in microservices

What is a Docker container?

• A virtual machine

• A file storage system

• A running instance of a Docker image

• A database management system

Which of the following is NOT a benefit of using Docker?

• Portability

• Isolation

• Increased hardware costs

• Resource efficiency

What is the primary role of the Docker Engine?

• Managing and creating virtual machines

• Running containerized applications

• Replacing cloud-based deployment

• Acting as a load balancer

What problem does Docker solve for developers?

• Inconsistent runtime environments across different machines

• Slow network speeds

• Lack of database support

• Incompatibility with Windows

Which component in Docker allows you to manage multi-container applications?

• Docker Hub

• Docker Engine

• Docker Compose

• Kubernetes

Why is containerization useful for microservices?

• It forces all services to use the same technology stack

• It isolates services, allowing independent scaling and deployment

• It eliminates the need for APIs

• It requires fewer servers than traditional applications

What does Docker Hub provide?

• A centralized repository for Docker images

• A tool for managing virtual machines

• A replacement for container orchestration tools

• A logging service for cloud applications

What is the main advantage of using Docker in DevOps?

• It reduces the need for developers to write application code

• It eliminates the need for version control

• It ensures consistency across development, testing, and production environments

• It removes the need for cloud services
