질문 # 90
Ifdocker stackis to be used to run a Docker Compose file on a Docker Swarm, how are the images referenced in the Docker Compose configuration made available on the Swarm nodes?
정답：C
설명：
Explanation
Docker stack is a command that allows users to deploy and manage a stack of services on a Docker Swarm cluster. A stack is a group of interrelated services that share dependencies and can be orchestrated and scaled together. A stack is typically defined by a Compose file, which is a YAML file that describes the services, networks, volumes, and other resources of the stack. To use docker stack to run a Compose file on a Swarm, the user must first create and initialize a Swarm cluster, which is a group of machines (nodes) that are running the Docker Engine and are joined into a single entity. The Swarm cluster has one or more managers, which are responsible for maintaining the cluster state and orchestrating the services, and one or more workers, which are the nodes that run the services.
When the user runs docker stack deploy with a Compose file, the command parses the file and creates the services as specified. However, docker stack does not build or upload the images referenced in the Compose file to any registry. Instead, it instructs the Swarm nodes to pull the images from a registry, which can be the public Docker Hub or a private registry. The user must ensure that the images are available in the registry before deploying the stack, otherwise the deployment will fail. The user can use docker build and docker push commands to create and upload the images to the registry, or use an automated build service such as Docker Hub or GitHub Actions. The user must also make sure that the image names and tags in the Compose file match the ones in the registry, and that the Swarm nodes have access to the registry if it is private. By pulling the images from a registry, docker stack ensures that the Swarm nodes have the same and latest version of the images, and that the images are distributed across the cluster in an efficient way.
The other options are not correct. Docker stack does not build the images locally or on the Swarm nodes, nor does it copy or transfer the images to the Swarm nodes. Dockerstack also does not pass the images to the Swarm master, as this would create a bottleneck and a single point of failure. Docker stack relies on the registry as the source of truth for the images, and delegates the image pulling to the Swarm nodes. References:

Which container orchestration platform is often associated with automated scaling and load balancing?
정답：D
설명：
Kubernetesis the container orchestration platform most strongly associated withautomated scaling and load balancing. According to container orchestration documentation, Kubernetes provides built-in features such as Horizontal Pod Autoscaling, service-based load balancing, self-healing, and declarative deployment models.
Docker Compose and LXC are not orchestration platforms at scale, and while Amazon ECS supports scaling, Kubernetes is the industry-standard platform most commonly referenced for these capabilities.
Therefore, the correct answer isB.
질문 # 92
After creating a new Docker network using the following command:
docker network create --driver bridge isolated_nw
which parameter must be added todocker createin order to attach a container to the network?
정답：A
설명：
To attach a container to a network when creating it, the --network flag must be used with the name of the network as the argument. The --network flag specifies the network mode for the container. By default, the network mode is bridge, which means the container is connected to the default bridge network. However, if a custom network is created, such as isolated_nw in this case, the container must be explicitly attached to it using the --network flag. For example, to create a container named web1 and attach it to the isolated_nw network, the command would be:
docker create --name web1 --network isolated_nw nginx
The other options are not valid parameters for docker create. The --eth0, --ethernet, and --attach flags do not exist. The --alias flag is used to specify an additional network alias for the container on a user-defined network, but it does not attach the container to the network. References:
* docker network create | Docker Documentation1
* docker create | Docker Documentation

Which of the following commands executes a command in a running LXC container?
정답：A
설명：
The command lxc-attach is used to execute a command in a running LXC container. It allows the user to start a process inside the container and attach to its standard input, output, and error streams1. For example, the command lxc-attach -n mycontainer -- ls -lh /home will list all the files and directories in the /home directory of the container named mycontainer1. The other options are not valid LXC commands. The command lxc- batch does not exist. The command lxc-run is an alias for lxc-start, which is used to start a container, not to execute a command in it2. The command lxc-enter is also an alias for lxc-attach, but it is deprecated and should not be used3. The command lxc-eval is also not a valid LXC command. References:

* 2: lxc-start: start a container. - SysTutorials.
* 3: lxc-attach: start a process inside a running container. - SysTutorials.
