When choosing a data persistence strategy in Docker, which factor should be considered carefully?
The version of Docker being used.
The color scheme of the Docker logo.
The sensitivity and importance of the data being stored.
The number of containers running on the host.
What is a key benefit of using a private Docker Registry in a continuous integration/continuous deployment (CI/CD) pipeline?
It simplifies the process of building images from source code.
It eliminates the need for image version control.
It enables faster and more controlled image distribution within the pipeline.
It allows for easier public image discovery.
Which command is used to initialize a Docker Swarm?
docker swarm up
docker swarm create
docker swarm start
docker swarm init
What is the primary function of a Docker Registry?
Running Docker containers in production
Storing and distributing Docker images
Managing network traffic between containers
Building Docker images
How can you create a custom network with specific configurations (e.g., IP range, driver) in Docker Compose?
By defining the network within the services section of the docker-compose.yml file
services
docker-compose.yml
By using the docker network create command separately and referencing the network in the docker-compose.yml file
docker network create
Docker Compose does not allow custom network configurations
By specifying the network configurations within the networks section of the docker-compose.yml file
networks
How do you stop a running Docker container named 'mycontainer'?
docker down mycontainer
docker kill mycontainer
docker stop mycontainer
docker halt mycontainer
What information does the 'docker inspect' command provide?
Low-level information about a container, image, or network
Real-time resource usage of a running container
The status (running/stopped) of a container
A list of all environment variables in a container
What is the primary advantage of using multi-stage builds in Docker?
To enable parallel execution of build steps.
To reduce the size of the final Docker image.
To simplify the process of building complex applications.
To improve network performance during the build process.
What is the primary purpose of Docker Swarm?
Building Docker images faster
Deploying and managing containerized applications at scale
Scanning Docker images for vulnerabilities
Storing and versioning Docker images
What is the purpose of volume drivers in Docker?
To improve the performance of volume operations.
To restrict container access to specific volumes.
To manage the lifecycle of bind mounts.
To enable the use of remote storage or cloud-based solutions for volumes.
